ACM SIGMM Executive Committee Newsletter – 1, 2022

The Special Interest Group in Multimedia of ACM, ACM SIGMM, provides a forum for researchers, engineers, and practitioners in all aspects of multimedia computing, communication, storage, and applications. We do this through our sponsorship and organization of conferences and workshops, supporting student travel to such events, discounted registrations, two regional chapters, recognition of excellence and achievement through an awards scheme, and we inform the Multimedia community of our activities through the SIGMM Records, social media and through mailing lists. Information on joining SIGMM can be found at

The SIGMM Executive Committee Newsletter in SIGMM Records periodically reports on the topics discussed and the decisions assumed in the Executive Committee meetings to improve transparency and sense of community. 

SIGMM Executive Committee Meeting 2022-03-16

Attended: Alberto Del Bimbo (Chair); Phoebe Chen (Vice-Chair); Miriam Redi (Conference Director); Changsheng Xu, Ketan Mayer-Patel, Kiyoharu Aizawa, Pablo Cesar, Prabhakaran, Balakrishnan, Qi Tian, Susanne Boll, Tao Mei, Abdulmotaleb El Saddik, Alan Smeaton (SIGMM Executive Committee members); Xavier Alameda Pineda (Invited guest)

Sent justification and comments: Lexing Xie (SIGMM Executive Committee member). 

We discussed the 2022 SIGMM budget. The SIGMM budget is in a good shape, and we foresee room for new initiatives to strengthen and expand the SIGMM community and improve our communication via existing and new channels.  

We approved a revision of SIGMM bylaws (proposed by Susanne Boll) to improve diversity: the chair and vice-chair will run for the offices in pairs; a way to encourage diversity without necessarily having to put quota. The proposal has been sent to ACM for approval. 

We approved three proposals for special initiatives that will improve inclusion. In late 2021, the SIGMM Executive invited SIGMM Members to apply for funding for new initiatives building on SIGMM’s excellence and strengths, nurturing new talent in the SIGMM community, and addressing weaknesses in the SIGMM community and in SIGMM activities. The fund can support auditable expenses incurred and necessary for the completion of the initiative. The proposals received were evaluated based on impact and contribution to the SIGMM community, and cost-effectiveness of the proposed budget. The three special initiatives approved so far are:

  • Multi-City PhD-School (proposed by the Steering Committee Co-Chairs of MM Asia)
    This is a two-half day program which is planned to be implemented in ACM MM Asia and eventually applied to other conferences in the future. The program is hosted in 3-5 satellite sites located in different Asian cities. Each site will physically gather 30-50 PhD students plus 1-2 senior researchers in a local venue. Different sites are virtually connected by online meetings. Invited student speakers will deliver a 3-minute lightning talk in turn followed by QA talks with mentors. The program allows students to physically attend the event, talk to senior researchers, while increasing the impact of satellite events among young researchers. Students are encouraged to register for the satellite events and attend virtually. This could involve more students and minority attendees with satellite events bringing students from multiple cities for idea exchange and research training
  • MMSys inclusion initiative (proposed by the MMSys’22 General Chairs & Diversity Chairs)
    The goal of this initiative is to improve diversity and inclusion in the MMSys community. The proposal includes 1) Travel support for non-student participants who self-identify as marginalized and/or underrepresented, lacking other funding opportunities; 2) an EDI (Equality, Diversity and Inclusion) panel aiming at increasing visibility and recognition of minorities and under-represented researchers in SIGMM fields, stimulating new collaborations; and promoting networking and mentoring between junior and senior researchers.
  • IMX Inclusion initiative (proposed by the IMX’22 Diversity Chairs)
    The goal of this initiative is to promote the participation of groups of students and researchers that have historically been underrepresented in the IMX’s community. The proposal includes funding for 1) a panel discussion on diversity in the metaverse; 2) travel support for individuals who self-identify as marginalized and/or underrepresented in terms of gender, race, and geographical location and who lack the financial resources to attend an international conference.

The SIGMM Executive also discussed two other initiatives, namely the opportunity of using Open Review in the SIGMM flagship conference ACM Multimedia (this year it is adopted on an experimental basis in ACMMM 2022), and the project of a reproducibility platform for open streaming evaluation and benchmarking (proposed by Ali Begen) eventually extendible beyond streaming media.  They both will be further discussed and evaluated in the next future.

The Chairs of the SIGMM Executive Committee

Introducing the new role of the Director of Diversity and Outreach


Over the last few decades SIGMM has grown with regard to the number and size of conferences and workshops we organize and sponsor, and we have grown with regard to our international outreach. Researchers from all over the world now participate in SIGMM and its many activities. In the same way in which we grow internationally with regard to members, with regard to the participants attending our conferences and their different backgrounds, the diversity of SIGMM is also growing. However, we can observe that diversity and all the aspects it brings to a society is not necessarily “just something” but needs to be supported and embraced by a cultural change of the organization and all its members.

Introducing the new role of SIGMM Director of Diversity and Outreach

In 2019, SIGMM created the new role of SIGMM Director of Diversity and Outreach with a variety of roles and responsibilities, for an initial 3-year period. Creation of this position is a sign and an action to establish future activities and an invitation on a more formal level to move our work in this area beyond anecdotal activities and personal engagement. The Director of Diversity and Outreach will be a voting member of the SIGMM Executive Committee. The EC Chair has drafted and circulated a role specification for this and sent a call to the community for expressions of interest in the role in Spring 2019. The confirmation of an appointment was made by the EC in May 2019. For the inaugural appointment 2019-2021, Susanne Boll has has been elected unanimously for this role. With this new director of diversity and outreach, SIGMM is supporting and developing diversity on an institutional level as a voting member of the SIGMM Executive Committee.

First Initiative

As a first initiative, the SIGMM EC has decided on a “25 in 25’’ strategy to strategically increase the participation of women in SIGMM and all its activities. This strategy aims at increasing the participation of women in all activities and committees of SIGMM to at least 25% by 2025. 

It can be observed that female participation in SIGMM has been low over many years. Even though there were good initiatives over the last decades, we have failed to include a proportionate number of women researchers into the SIG and into our executive structures and event organization. As we observe that about 25% of all CS degrees in computer science are held by women, we may well expect that ACM find these numbers reflected in the number of women active within their Special Interest Groups –  which is not the case in SIGMM. We strongly believe that it will only change if we as SIGMM take action. This action will take place on three levels. 

With the SIGMM Executive Actions we aim at an obligatory inclusion of women in the steering committees of SIGMM. For the coming elections in 2021, we will implement a voting scheme by which the two leading chair positions, SIGMM Chair and SIGMM Vice Chair, will be filled by a man and a woman. For the forthcoming SIGMM officer elections, SIGMM will also fill other candidate roles with two individuals, one man and one woman to ensure gender equality on the level of the different roles. 

With the SIGMM Conference Steering Actions for all forthcoming appointments to the individual Steering Committees, the Steering Committees will invite female candidates in order to reach at least a 25% share of their memberships. All Steering Committees will have their members online and maintain a history of their SC and the different positions on the organizing committee of their related conferences online.

With the SIGMM Conference Actions we request that all SIGMM-sponsored conferences have at least 25% representation of women in all roles of their organizing committee which will be observed for all forthcoming bids for conferences.  We aim at organising committees in which the many volunteer roles for our conferences, such as general chair, workshop chair, tutorial chair, panel chair, web chair, local chair, or proceedings chair could be filled by two individuals, one woman and one man.  

The SIGMM Director of Diversity and Outreach will observe the implementation of these rules and report on the state and progress annually within the EC, at the annual SIGMM business meeting at ACM Multimedia and publish a report in SIGMM Records.

What’s next?

The creation of the role of the  SIGMM Director of Diversity and Outreach was a first step. The initiative “25 in 25” is the first set of initiatives and further initiatives will follow. Currently, we are already in discussion about actions across SIGMM events such as travel support, childcare, mentoring support, support for speakers and targeted meetings. We will regularly inform you through our regular newsletter, website, and meetings. 

SIGMM understands the new role as actively pushing and developing diversity and outreach within SIGMM. The new director is here to listen and to act for a better diversity of our Special Interest Group MM, our activities and our outreach to the multimedia community.  All SIGMM members are strongly invited to support the activities of the director of outreach and the different initiatives. The director will also seek and actively exchange with and learn from other Special Interest Groups within ACM and other societies. If you want to get involved please join us (contact: Susanne Boll

Gender Diversity in SIGMM: We’ll Just Leave This Here As Well


1. Introduction and Background

SIGMM is the Association for Computing Machinery’s (ACM) Special Interest Group (SIG) in Multimedia, one of 36 SIGs in the ACM family.  ACM itself was founded in 1947 and is the world’s largest educational and scientific society for computing, uniting computing educators, researchers and professionals. With almost 100,000 members worldwide, ACM is a strong force in the computing world and is dedicated to advancing the art, science, engineering, and application of information technology.

SIGMM has been operating for nearly 30 years and sponsors 5, soon to be 6, major international conferences each year as well as dozens of workshops and an ACM Transactions Journal.  SIGMM sponsors several Excellence and Achievement Awards each year, including awards for Technical Achievement, Rising Star, Outstanding PhD Thesis, TOMM best paper, and Best TOMM Associate Editor award. SIGMM funds student travel scholarships to almost all our conferences with nearly 50 such student travel grants at the flagship MULTIMEDIA conference in Seoul, Korea, in 2018.  SIGMM has two active chapters, one in the Bay Area of San Francisco and one in China. It has a very active online activity with social media reporters at our conferences, a regular SIGMM Records newsletter, and a weekly news digest.  At our flagship conference, SIGMM sponsors Women and diversity lunches, Doctoral Symposiums, and a newcomers’ welcome breakfast.  SIGMM also funds special initiatives based on suggestions/proposals from the community as well as a newly-launched conference ambassador program to reach out to other ACM SIGs for collaborations across our conferences.

It is generally accepted that SIGMM has a diversity and inclusion problem which exists at all levels, but we have now realized this and have started to take action.  In September 2017 ACM SIGARCH produced the first of a series of articles on gender diversity in the field of Computer Architecture. SIGARCH members looked at their numbers of representation of women in SIGARCH conferences over the previous 2 years and produced the first of a set of reports entitled “Gender Diversity in Computer Architecture: We’re Just Going to Leave This Here”.


This report generated much online debate and commentary, including at the ACM SIG Governing Board (SGB) meetings in 2017 and in 2018.

At a SIGMM Executive Committee meeting in Mountain View, California in October 2017, SIGMM agreed to replicate the SIGARCH study to examine and measure, the (lack of) gender diversity at SIGMM-sponsored Conferences.  We issued a call offering funding support to do this, but there were no takers, so I did this myself, from within my own research lab.

2. Baselines for Performance Comparison

Before jumping into the numbers it is worth establishing a baseline to measure against. As an industry-wide figure, 17-24% of Computer Science undergrads at US R1 institutions are female as are 17% of those with technical roles at large high-tech companies that report diversity. I also looked at the female representation within some of the other ACM SIGs. While we must accept that inclusiveness and diversity is not just about gender but also about race, ethnicity, nationality, even about institution, we don’t have data on these other aspects so I focus just on gender diversity.

So how does SIGMM compare to other SIGs? Let’s look at SIG memberships using data provided by ACM.

The best (most balanced or least imbalanced) SIGs are CSE (Computer Science Education) with 25% female, Computer Human Interaction (CHI) also with 25% female from among those declaring a gender, though CHI is probably better because it has a greater percentage of undeclared gender, thus a lower proportion of males. The worst SIGs (most imbalanced or least balanced) are PLAN (Programming Languages) with 4% female, and OPS (operating systems) with 5% female.


The figures for SIGMM show 9% female membership with 17% unknown or not declaring which means that among the declared members it is just below 11%. Among the other SIGs this makes us closest to AI (Artificial Intelligence) and to IR (Information Retrieval), though SIGIR has a larger number of members with gender undeclared.


Measuring this against overall ACM memberships we find that ACM members are 68% male, 12% female and 20% undeclared. This makes SIGMM quite mid-table compared to other SIGs, but we’re all doing badly and we all have an imbalance. Interestingly, the MULTMEDIA Conference in 2018 in Seoul, Korea had 81% male, 18% female and 1% other/undeclared attendees, slightly better than our memberships ratio but still not good.

3. Gender Balance at SIGMM Conferences

We [1] carried out a desk study for the 3 major SIGMM conferences, namely MULTIMEDIA with an average attendance of almost 800, the International Conference on Multimedia Retrieval (ICMR) with 230 attendees at the last conference and Multimedia Systems (MMSys) with about 130 attendees. For each of the last 5 years we trawled through the conference websites, extracting the names/affiliations of the organizing committees, the technical program committees and the invited keynote speakers.  We did likewise for the SIGMM award winners. This required us determining gender for over 2,700 people and although there were duplicates as the same people can recur on the program committees for multiple years and over multiple conferences. Some of these were easy like “John” and “Susanne”, but these were few so for the others we searched for them on the web. If we were still searching after 5 minutes, we gave up. [2]

[1] This work was carried out by Agata Wolski, a Summer intern student, and I, during Summer 2018.

[2] The data gathered from this activity is available on request from

The figures for each of these annual conferences for a 5-year period for MULTIMEDIA, for a 4-year period for ICMR and for a 3-year period for MMSys, are shown in the following sequence of charts, first showing the percentages and then the raw numbers, for each conference.







So what do the figures mean in comparison to each other and to our baseline?

The results tell us the following:

  • Almost all the percentages for female participation in the organisation of all SIGMM conferences are above the SIGMM membership figure of 9% which is really closer to 11% when discounting those SIGMM members with gender unassigned yet we know the number of female SIGMM members is much already smaller compared to the 17% female in technology companies and the almost 18% female ACM members when discounting unassigned genders.
  • Even if we were to use 17% to 18% figures as our baseline, our female participation in SIGMM conference organisation is less than that baseline, meaning our female SIGMM members are not appearing in organisational and committee roles as per our membership pro rates would indicate they should.
  • While each of our conferences fall below these pro rata figures, none of the three conferences are particularly worse than the others.

4. Initiatives Elsewhere to Redress Gender Imbalance

I then examined some of the actions that are carried out elsewhere and that SIGMM could implement, and started by looking at other ACM SIGs.  There I found that some of the other SIGs do some of the following:

  • women and diversity events at conferences (breakfasts or lunches, like SIGMM does)
  • Women-only networking pre-conference meals at conferences
  • Women-only technical programme events like N2Women
  • Formation of mentoring group (using Slack) for informal mentoring
  • Highlighting the roles and achievements of women on social media and in newsletters
  • Childcare and companion travel grants for conference attendance

I then looked more broadly at other initiatives and found the following:

  • gender quotas
  • accelerator programs like Athena Swan
  • female-only events like workshops
  • reports like this which act as spotlights

When we put these all together there are three recurring themes which appear across various initiatives:

  1. Networking .. encouraging us to be part of a smaller group within a larger group. This is a natural human trait of us being tribal, we like to belong to groups starting with our family but also the people we have lunch with, go to yoga classes with, go on holidays with, we each have multiple sometimes non-overlapping groups or tribes that we like to be part of. One such group is the network of minority/women that gets formed as a result of some of the activities.
  2. Peer-to-peer buddying .. again there is a natural human trait whereby older siblings (sisters) tend to help younger ones throughout life, from when we are very young and right throughout life.  The buddying activity reflects this and gives a form of satisfaction to the older or senior buddy, as well as practical benefit to the younger or more junior buddy.
  3. Role models .. there are several initiatives which try to promote role models as those kinds of people that we ourselves can try to aspire to be.  More often that not, it is the very successful people and the high flyers who are put into these positions of role models whereas in practice not everyone actually wants to aspire to be a high flyer.  For many people success in their lives means something different, something less lofty and aspirational and when we see high flying successful people promoted as role models our reaction can be the opposite. We can reject them because we don’t want to be in their league and as a result we can feel depressed and regard ourselves as under-achievers, thus defeating the purpose of having role models in the first place.

5. SIGMM Women’s / Diversity Lunch at MULTIMEDIA 2018

At the ACM MULTIMEDIA Conference in Seoul, Korea in October 2018 SIGMM once again organised a women’s / diversity lunch and about 60 people attended, mostly women.


At the event I gave a high level overview of the statistics presented earlier in this report, and then in order to gather feedback from the audience we held a moderated discussion with PadLet used to gather feedback. PadLet is an online bulletin board used to display information (text, images or links) which can be contributed anonymously from an audience. Attendees at the lunch scanned a QR code on their smartphones which opened a browser and allowed them to post comments on the big screen in response to a topic being discussed during the meeting.

The first topic discussed was “What brings you to the MULTMEDIA Conference?

  • The answers (anonymous comments) posted included that many are here because they are presenting papers or posters, many want to do networking and to share ideas, to help build the community of like-minded researchers, some are attending in order to meet old friends .. and these are the usual reasons for attending a conference.

For the second topic we asked “What excites you about multimedia as a topic, how did you get into the area?

  • The answers included the interaction between computer vision and language, the novel applications around multimodality, the multidisciplinary nature and the practical nature of the subject, and the diversity of topics and the people attending.

The third topic was “What is more/less important for you … networking, role models or peer buddies?

  • From the answers to this, networking was almost universally identified as the most important, and as a follow-on from that, interacting with peers

Finally we asked “Do you know of an initiative that works, or that you would like to see at SIGMM event(s)?

  • A variety of suggestions were put forward including holding hackathons, funding undergraduate students from local schools to attend the conference, an ACM award for women only, ring-fenced funding for supporting women only, training for reviewing, and a lot of people wanted mentoring and mentor matching.

6. SIGMM Initiatives

So what will we do in SIGMM?

  • We will continue to encourage networking at SIGMM sponsored conferences. We will fund lunches like the ones at the MULTIMEDIA Conference. We also started a newcomers breakfast at the MULTIMEDIA Conference in 2018 and we will continue with this.
  • We will ensure that all our conference delegates can attend all conference events at all SIGMM conferences without extra fees. This was a SIGMM policy identified in a review of SIGMM conference some years ago but it has slipped.
  • We will not force but we will facilitate peer-to-peer buddying through the networking events at our conferences and through this we will indirectly help you identify your own role models.
  • We will appoint a diversity coordinator to oversee the women / diversity activities across our SIGMM events and this appointee will be a full member of the SIGMM Executive Committee.
  • We will offer an opportunity for all members of our SIGMM community attending our sponsored conferences, as part of their conference registration, to indicate their availability and interest in taking on an organisational role in SIGMM activities, including conference organisation and/or reviewing. This will provide for us a reserve of people from whom we can draw on their expertise and their services and we can do so in a way which promotes diversity.

These may appear to be small-scale and relatively minor because we are not getting to the roots of what causes the bias and we are not inducing change to counter the causes of the bias. However these are positive steps, steps in the right direction, and we will now have the gender and other bias issues permanently on our radars.

SIGMM Records: News, Statistics, and Call for Contributions & Suggestions


A new editorial team has committed to lead the ACM SIGMM Records since the issue of January 2017. The goal is to consolidate the Records as a primary source of information and a communication vehicle for the multimedia community. With these objectives in mind, the Records were re-organized around three main categories (Open Science, Information, and Opinion), for which specific sections and columns were created (more details in

statistics october 2018

Since then, all sections and columns have provided relevant and high-quality contributions, with a higher impact than anticipated. Since the new epoch of the Records, apart from new columns, two additional initiatives have been incorporated:

  • Best social media reporter: It was decided to award the SIGMM members with the most intense and valuable posts on Social Media during the SIGMM conferences. The selected Best Social Media Reporters are asked to provide a post-conference report to be published in the Records, and get a free registration to one of the upcoming SIGMM conferences. Up to now, the awardees have been: Miriam Redi (ICMR 2017), Christian Timmerer (MMSYS 2017), Benoit Huet and Conor Keighrey (MM 2017), Cathal Gurrin (ICMR 2018) and Gwendal Simon (MMSYS 2018). The criteria for the awards are specified here:
  • Section on QoE: Starting in the third issue of 2018 (September 2018), the Records include a new section on QoE, edited by Tobias Hoßfeld and Christian Timmerer. You can find here the introduction column: 

Apart from the recurrent sections, the community has as well contributed with relevant feature articles. Some examples include the article about the flow of ideas around SIGMM conferences by Lexing Xie, the article about ACM Fellows in SIGMM by Alan Smeaton, the SIGMM Annual Report (2018) by the Chairs, and an article about data driven statistics and trends in SIGMM conferences by David Ayman Shamma.

Finally, the editorial team is also working on infrastructural aspects together with ACM. First, an effective communication protocol with the ACM Digital Library has been established, enabling the publication of the issues and individual contributions in HTML format. SIGMM has indeed been pioneering in adopting the HTML format in the publication of articles. Second, the process for migrating the Records website to an ACM server and domain has started, and should be completed before the end of the year.

Pablo Cesar, the editor-in-chief, presented the new team, structure and impact at ACM MM 2017 and will update the community during ACM MM2018.

Reach of the SIGMM Records

Since August 2018, we have been collecting statistics about visitors and visits to the Records website, and making use of Social Media for disseminating the contributions and news. In these 13 months, the daily number of visitors have ranged approximately between 100 and 400, being this variation strongly influenced by the publication of Social Media posts promoting published contents. In these last 13 months, more than 80000 visitors and nearly 500000 visits (i.e. clicks) have been registered.

The top 3 countries with highest number of visitors are US (>19000), China (>10000) and Germany (nearly 7000), and the top 10 all surpass 2000 visitors. Likewise, the top 3 posts with highest impact, in terms of number of visits are listed in Table 1.

Table 1. Top 3 posts on the Records website with highest impact

Post Publication Date Number of Visits
Impact of the New @sigmm Records September 2017 3051 visits
Standards Column: JPEG and MPEG May 2017 1374 visits
Practical Guide to Using the YFCC100M and MMCOMMONS on a Budget October 2017 786 visits

Finally, the top 3 referring sites (i.e., external websites from which visitors have clicked an URL to access the Records website) are Facebook (around 2500 references), Google (around 2500 references) and Twitter (>700 references). According to this, it seems clear that the social media strategy implemented by the editorial team is positively impacting the Records.

Regarding Social Media, two @sigmm channels are being used: a Facebook page and a Twitter account (@sigmm). The number of followers is still not high in Facebook (47), but it has significantly increased in Twitter (247) compared to the previous report. However, the impact of the posts on these platforms, in terms of reach, likes and shares is noteworthy. In Facebook, there are posts that have reached more than 1000 users, and in Twitter there are many tweets with tens of re-tweets and likes.


Our mission is to keep improving and consolidate the Records, and we are very open to getting extra help and feedback. So, if you would like to become member of our team, or simply have suggestions or ideas, please drop us a line!

We hope you are enjoying every new edition of the Records.

The Editorial team

Impact of the New @sigmm Records

The SIGMM Records have renewed, with the ambition of continue being a useful resource for the multimedia community. The intention is to provide a forum for (open) discussion and to become a primary source of information (and of inspiration!).

The new team ( has committed to lead the Records in the coming years, gathering relevant contributions in the following main clusters:

The team has also revitalized the presence of SIGMM on Social Media. SIGMM accounts on Facebook and Twitter have been created for disseminating relevant news, events and contributions for the SIGMM community. Moreover, a new award has been approved: the Best Social Media Reporters from each SIGMM conference will get a free registration to one of the SIGMM conferences within a period of one year. The award criteria are specified at

The following paragraphs detail the impact of all these new activities in terms of increased number of visitors and visits to the Records website (Figure 1), and broaden reach. All the statistics presented below started to be collected since the publication of the June issue (July 29th 2017).

Figure 1. Number of visitors and visits since the publication of the June issue

Figure 1. Number of visitors and visits since the publication of the June issue

Visitors and Visits to the Records website

The daily number of visitors ranges approximately between 100 and 400. It has been noticed that this variation is strongly influenced by the publication of Social Media posts promoting contents published on the website. In the first month (since July 29th, one day after the publication of the issue), more than 13000 visitors were registered, and more than 20000 visitors have been registered until now (see Table 1 for detailed statistics). The number of visits to the different posts and pages of the website accumulates up to more than 100000. The top 5 countries with highest number of visitors are also listed in Table 2. Likewise, the top 3 posts with highest impact, in terms of number of visits and of Social Media shares (via the Social Media icons recently added in the posts and pages of the website) are listed in Table 3. As an example, the daily number of visits to the main page of the June issue is provided in Figure 2, with a total number of 224 visits since its publication.

Finally, the top 3 referring sites (i.e., external websites from which visitors have clicked an URL to access the Records website) are Facebook (>700 references), Google (>300 references) and Twitter (>100 references). So, it seems that Social Media is helping to increase the impact of the Records. More than 30 users have accessed the Records website through the SIGMM website ( as well.

Impact of the Social Media channels

The use of Social Media includes a Facebook page and a Twitter account (@sigmm). The number of followers is still not high (27 followers in Facebook, 88 followers in Twitter), which is natural with recently created channels. However, the impact of the posts on these platforms, in terms of reach, likes and shares is noteworthy. Tables 4 and 5 lists the top 3 Facebook posts and tweets, respectively, with highest impact up to now.

Awarded Social Media Reporters

The Social Media co-chairs, with the approval of the SIGMM Executive Committee, have already started the processes of selecting the Best Social Media Reporters from the latest SIGMM conferences. In particular, the winners have been Miriam Redi  from ICMR 2017 (her post-summary of the conference is available at: and Christian Timmerer for MMSYS 2017 (his post-summary of the conference is available at: Congratulations!

The Editorial Team would like to take this opportunity to thank all the SIGMM members who use Social Media channels to share relevant news and information from the SIGMM community. We are convinced it is a very important service for the community.

We will keep pushing to improve the Records and extend their impact!

The Editorial Team.

@sigmm Records: serving the community

The SIGMM Records are renewing, with the continued ambition of being a useful resource for the multimedia community. We want to provide a forum for (open) discussion, but also to become the primary source of information for our community.

Firstly, I would like to thank Carsten who was run, single-handed, the whole records for many many years. We all agree that he has done an amazing job, and that his service deserves our gratitude, and possibly some beers, when you meet him at conferences and meetings.

As you are probably aware, a number of changes in the records are underway. We want your opinions and suggestions to make this resource the best it can be. Hence, we need your help to make this a success, so please drop us a line if you want to join the team.

The two main visible changes are:

We have a new amazing team to lead the records in the coming years. I am so glad to have their help:

We have reorganized the records and its structure, in three main clusters:

More changes to come. Stay tuned!

Dear Member of the SIGMM Community, welcome to the last issue of the SIGMM Records in 2013.

The editors of the Records have taken to a classical reporting approach, and you can read here the first of series of interviews. In this issue, Cynthia Liem is interview by Mathias Lux, and explains about the Phenicx project.

We have received a report from the first international competition on game-based learning applications, and also our regular column reporting from the 106th MPEG meeting that was held in Geneva. Our open source column presents libraries and tools for threading and visualizing a large video collection in this issue, a set of tools that will be useful for many in the community. Beyond that, you also read about two PhD thesis.

Among the announcements are several open positions, and a long list of calls for paper. The long list of calls is achieved by a policy change in SIGMM. After several years that have seen our two public mailing lists, and, flooded by calls for papers, the board and online services editors have decided to change the posting policy. Both lists are now closed for public submissions of calls for paper and participation. Instead, calls must be submitted through the SIGMM Records web page, and will be distributed on the mailing list in a weekly digest. We hope that the members of the SIG appreciate this service, and that those of us who have filtered emails for years feel that this is a more appropriate policy.

With those news, we invite you to read on in this issue of the Records.

Dear Member of the SIGMM Community, welcome to the third issue of the SIGMM Records in 2013.

On the verge of ACM Multimedia 2013, we can already present the receivers of SIGMM’s yearly awards, the SIGMM Technical Achievement Award, the SIGMM Best Ph.D. Thesis Award, the TOMCCAP Nicolas D. Georganas Best Paper Award, and the TOMCCAP Best Associate Editor Award.

The TOMCCAP Special Issue on the 20th anniversary of ACM Multimedia is out in October, and you can read both the announcement, and find each of the contributions directly through the TOMCCAP Issue 9(1S) table of contents.

That SIGMM has established a strong foothold in the scientific community can also be seen by the Chinese Computing Federation’s rankings of SIGMM’s venues. Read the article to get even more motivation for submitting your papers to SIGMM’s conferences and journal.

We are also reporting from SLAM, the international workshop on Speech, Language and Audio in Multimedia. Not a SIGMM event, but certainly of interest to many SIGMMers who care about audio technology.

You find also two PhD thesis summaries, and last but most certainly not least, you find pointers to the latest issues of TOMCCAP and MMSJ, and several job announcements.

We hope that you enjoy this issue of the Records.

Dear Member of the SIGMM Community, welcome to the second issue of the SIGMM Records in 2013.

SIGMM has elected a new board, to guide the SIG through the next couple of years and develop it further. The new board, under the chairmanship of Professor Shih-Fu Chang introduces itself in this issue of the Records.

Among the first acts of the new board was the call for bids for ACM Multimedia 2016, announced also in this issue.

Of course, we have also several other contributions: the OpenSource column introduces  OpenIMAJ, while the MPEG column brings the press release for the 104th MPEG meeting. We can also reveal a change of leadership in FXPal, a research company with many SIGMM members in its ranks and a former SIGMM chair as departing president.

We put also a spotlight on the ongoing season for MediaEval, the multimedia benchmarking initiative, and we include four PhD thesis summaries in this issue.

Of course, we include also a variety of calls for contribution. Please give attention to two particular ones: TOMCCAP has chosen its special issue topic for 2014 and includes a call for papers in this issue of the Records. And also MTAP has issued a special issue call for paper.

Last but most certainly not least, you find pointers to the latest issues of TOMCCAP and MMSJ, and several job announcements.

We hope that you enjoy this issue of the Records.

Dear Member of the SIGMM Community, welcome to the first issue of the SIGMM Records in 2013.

This issue is full of opportunities that SIGMM gives you in 2013. Inside you find the calls for nominations for SIGMM’s three main awards: The SIGMM Technical Achievement Award, awarded for lasting contributions in our field, the SIGMM Award for Outstanding PhD Thesis, awarded for the best thesis in our field that was defended in the 12 months of 2012, and the Nicolas D. Georganas Best Paper Award for the best paper that was published in an issue of TOMCCAP in 2012.

One of the major changes in SIG life is upcoming: SIGMM elects new chairs, and we want to remind you to cast your vote. Our current chair, Klara Nahrstedt, gave an interview for the Records on the issue of ACM Fellowships.

Three PhD thesis summaries are included in this issue, and in our regular columns, you can read news from the 103rd MPEG meeting, in the education column you can learn about a practice book on visual information retrieval, and a toolset for DASH is presented in the open source column.

Of course, we include also a variety of calls for contribution. Please give attention to two particular ones: TOMCCAP is calling for special issue proposals, a major opportunity because TOMCCAP publishes only one special issue per year; and details about the ACM Multimedia Grand Challenges of 2013 are described in some detail. A lot of the other included calls refer to tracks and workshops of ACM Multimedia 2013, but also included are calls for some other events, and open positions.

Last but most certainly not least, you find pointers to the latest issues of TOMCCAP and MMSJ, and several job announcements.

We hope that you enjoy this issue of the Records.
