Nicolas D. Georganas Best Paper Award

The ACM Transactions on Multimedia Computing, Communications and Applications (TOMM), 2014

The 2014 ACM Transactions on Multimedia Computing, Communications and Applications (TOMM) Nicolas D. Georganas Best Paper Award is presented to the paper “A framework for network aware caching for video on demand systems” (TOMM vol. 9, Issue 4) by Bogdan Carbunar, Rahul Potharaju, Michael Pearce, Venugopal Vasudevan and Michael Needham.

The purpose of the named award is to recognize the most significant work in ACM TOMM (formerly TOMCCAP) in a given calendar year. The whole readership of ACM TOMM was invited to nominate articles which were published in Volume 9 (2013). Based on the nominations the winner has been chosen by the TOMM Editorial Board. The main assessment criteria have been quality, novelty, timeliness, clarity of presentation, in addition to relevance to multimedia computing, communications, and applications.

The winning paper examines caching strategies for video-on-demand solutions using log traces collected from Motorola equipment deployed within several Comcast sites. The authors propose several fundamental metrics for characterizing video-on-demand CDN architectures and contribute several caching strategies based on observations extracted from real-world data. The superior performance of the proposed solutions make the work highly relevant for both video-on-demand providers (e.g., to improve caching strategies) and academics (e.g., designing realistic simulators using the characterizations outlined in the paper).

The award honors the founding Editor-in-Chief of TOMM, Nicolas D. Georganas, for his outstanding contributions to the field of multimedia computing and his significant contributions to ACM.  He exceedingly influenced the research and the whole multimedia community.

The Editor-in-Chief Prof. Dr.-Ing. Ralf Steinmetz and the Editorial Board of ACM TOMM cordially congratulate the winner. The award will be presented on November 4th 2014 at the ACM Multimedia 2014 in Orlando, Florida.

SIGMM Award for Outstanding Technical Contributions to Multimedia Computing, Communications and Applications

The 2014 winner of the prestigious ACM Special Interest Group on Multimedia (SIGMM) award for Outstanding Technical Contributions to Multimedia Computing, Communications and Applications is Prof. Dr. Klara Nahrstedt.

Klara Nahrstedt is a leading researcher in multimedia systems. She has made seminal contributions in QoS management for distributed multimedia systems. Her pioneering work on QoS brokerage with QoS translation, QoS negotiation and QoS adaptation services set between application and transport layers to enable end-to-end QoS contract changed the way multimedia end-system architectures are designed and built. This result was published as the “QoS Broker” in 1995. Her novel QoS adaptation extended this work by modeling the end-to-end QoS problem based on a control-theoretical approach. This work gained wide recognition as the first usage of control theory in multimedia systems and received the Leonard C. Abraham Paper Award from the IEEE Communication Society.

Addressing the end-to-end QoS management problem, she made fundamental contributions to QoS routing. In her 1999 JSAC paper “Distributed Quality of Service Routing in Ad-hoc Networks” she derived a  distributed time and  bandwidth  sensitive  routing  scheme  for a dynamic multi-hop mobile environment. Her IEEE Network Magazine paper, “An Overview of Quality-of-Service Routing for the Next Generation High-Speed Networks: Problems and Solutions” received the “Best Tutorial Paper” Award from the IEEE Communication Society in 1999 and is still highly relevant today.

She has made seminal contributions to multimedia wireless networks.  Her novel  pricing  scheme  for  ad  hoc  networks using pricing for a clique of nodes that interfere with each other, as opposed to the per connection pricing as it was done in wired networks, as well as her results on cross-layer QoS approaches, including bandwidth and delay management, found a wide acceptance and acknowledgement in industry.

She has made seminal contributions in the area of multimedia scheduling for mobile devices. Her fundamental work on energy-efficient dynamic soft-real-time CPU scheduling for mobile multimedia devices, and development of first energy-efficient OS for mobile multimedia devices, GRACE-OS, has been widely recognized in academia and industry.

She leads the 3D tele-immersive systems and networking field. She was the first one to develop a multi-view 3D video adaptation framework for bandwidth management and view-casting protocols for multi-view 3D video. She has developed new metrics for 3D immersive video and the first comprehensive framework based on sound theoretical underpinnings for Quality of Experience in Distributed Interactive Multimedia Environments. This work was awarded Best Student Paper Award at the premier SIGMM conference, ACM Multimedia 2011, and her PhD student received the SIGMM 2012 Best PhD Thesis Award as a result.

Her two textbooks Multimedia Systems (with R. Steinmetz, Springer-Verlag, 2004) and Multimedia Computing, Communications and Applications (with R. Steinmetz, Prentice Hall, 1995) are among the world’s most widely used text-books on multimedia technology. They present the entire field of multimedia technology in a comprehensive manner.

Prof. Nahrstedt’s research leadership has translated into several awards including the 2009 Humboldt Fellow Research Award, the 2012 IEEE Computer Society Technical Achievement Award, the 2013 ACM Fellow recognition and the 2014 induction into the German National Academy of Sciences.

In summary, Prof. Nahrstedt’s accomplishments include her pioneering and extraordinary contributions in quality of service for multimedia systems and networking and her visionary leadership of the computing community.

The award will be presented on November 5th 2014 at the ACM Multimedia Conference in Orlando, Florida.

ImproveMyCity – An open source platform for direct citizen-government communication

Motivation & Overview

In modern societies there is a growing requirement for public administrations to directly communicate with their citizens, view the existing problems from their perspective and re-act to their needs. In meeting this requirement, modern technologies have become a particularly valuable instrument that, apart from being a rich source of information, is also an integral part of our daily activities. Web and mobile civic engagement apps are able to transform citizens into the living sensors of their city and, in this way, help them to actively participate in the improvement of their neighborhood. Fulfilling this goal, ImproveMyCity is a platform that, on the one hand, enables citizens to directly report issues about their neighborhood (e.g. potholes, illegal trash dumping, faulty street lights, broken tiles on sidewalks, and illegal advertising boards), and, on the other hand, provides the necessary back-end infrastructure and interfaces for public servants to keep track of the reported issues, schedule their settlement and provide feedback to the citizen about the progress status. The reported cases go directly into the city’s work order queue for resolution, and users are informed how quickly the case will be closed. When cases are resolved the date and time of the resolution is listed, providing users with the sense that the city is on the job. In this way, ImproveMyCity helps Municipalities to enlist new segments of the population —people who had not previously participated in government—and bring their concerns, insight, energy, and commitment to reinvigorate not only the city but also the government.

 

Video 1:Core concept of ImproveMyCity.

The ImproveMyCity platform is structured as a client-server application and is implemented as an extension of the Joomla framework. The platform consists of a web- based portal for allowing citizens to report issues from their desktop PC, a smartphone application for android devices that allows citizens to do the same process through their mobile phone and a back-end infrastructure for allowing the governmental agencies to easily handle the reported issues. The source code is available in GitHub both for the web-based front-end and the back-end infrastructure, as well as for the mobile front-end. All source codes are provided with detailed user guides explaining how to download and install the applications and are licensed under the under the GNU Affero General Public License. The web-based front-end and back-end infrastructure are also available through the official Joomla Extension Directory (JED).

Service model & Key features

The service model of ImproveMyCity is based on three main pillars: Report – Administer – Analyze. City residents are urged to directly report to their public administration local issues about their neighborhood. Subsequently, the reported issues are automatically transmitted to the appropriate office in public administration so as to schedule their settlement. The administration (i.e. management and routing) of incoming issues is performed through a back-end infrastructure that serves as an integrated management system, allowing the governmental agencies to easily handle the reported issues. Finally, data analysis is performed through a visual analytics tool that employs heatmap-based visualizations and spatio-temporal filters with the aim to offer decision makers valuable insights for improving the city operation. The key features can be summarized as follows:  

Report – Citizens requests, complaints & suggestions
  • Submitted via web or mobile: By allowing citizens to report issues from their home using the web version, or while on the street using the mobile app (iOS &Android)
  • Easily composed but descriptive: By asking citizens to provide only the information necessary to locate and resolve the issue, such as title, description, location and category.
  • Accurately positioned: By offering a map to facilitate citizens in determining the exact location of their issue.
  • Picture enabled: By allowing to attach an image on the spot for describing the issue.
  • Categorized based on their nature: By urging citizens to select one of the pre-specified categories reflecting the municipality departments.
  • Commented and voted: By offering the mechanisms to post comments or vote for issues that have been submitted by other citizens.
Administer – Citizens issues through an integrated management system
  • Browse effectively: Issues are presented on the city map, as an ordered list but also in a single-issue page displaying the full set of submitted details.
  • Distribute responsibilities: Assign one or more officers per category and split the administration effort across the municipality departments.
  • Track pending issues: Issues are automatically routed not only to the appropriate department but also to the inbox of the responsible officer.
  • Monitor progress and update citizens: Resolve issues and inform citizens by email or through a progress indication bar (Open->Acknowledged->Closed).
  • Provide direct feedback: Provide written feedback to the citizens giving non-standard explanations for each specific case.
  • Customize easily: Fully customize the system in terms of user rights, number and nature of categories, notification rules and localization settings.

 

Analyse – Citizens data to gain city insights
  • Filter and explore: Combine temporal filters with free keyword-based search and dynamically explore citizens’ data through interactive visualizations.
  • Aggregate and visualize: Aggregate data based on their spatial density or statistical frequency and visualize them using heatmaps, tag-clouds, color codes and pie charts.
  • Discover hidden patterns: Observe spatio-temporal tendencies, unexpected periodicities, significant outliers, popular issues and prevailing terms.
  • Translate patterns into insights: Identify areas with dissatisfied citizens, under-performing departments due to heavy workload, seasonal burden on city infrastructures, etc.

 

Interface & Installation

The ImproveMyCity platform consists of four main interaction components: a) The web-based front-end for reporting issues through a desktop PC, b) The smartphone-based front-end for reporting issues through a mobile phone, c) the back-end infrastructure and related interfaces for administering the incoming issues, and d) the analyics component for visualizing the reported issues in an interactive manner.

Figure 2: Web-based front-end for issue reporting.

Figure 3: Mobile apps for issue reporting.

Figure 4: Integrated system for managing incoming issues.

Figure 5: Visual analytics for dynamic data exploration.

Since the web-based front-end and the back-end infrastructure and interfaces are developed as standard Joomla components, their installation and running is a plain process. Indeed after a few simple steps the ImproveMyCity back-end infrastructure and the web-based front-end are ready to be used and administered. Similarly, the mobile front-end requires a few extra steps, so as to connect with the server and get synchronized with the web-based front-end. Moreover, due to its nature, ImproveMyCity has been specifically designed to make fully customizable all parameters needed to localize the platform for a certain city. In this respect all language-related menus, geo-positioning related parameters and layout options, are accessible through external files that can be easily edited. Moreover, particular attention has been placed on language-based localization by initiating and maintaining a crowdsourcing project in Transifex.

User-centered design

ImproveMyCity has been developed in close cooperation with the end-users in a co-design process with successive innovation cycles. More specifically, particular attention has been paid in engaging the end-users during the functional and aesthetic design of the application. After identifying the end-user groups (i.e. city stakeholders, citizens, service providers and city visitors), the development team of ImproveMyCity has followed a systematic approach for bringing these groups into the application design loop, including: a) Users’ briefing through informative events focused on specific topics / user groups – including their follow-ups, informative media (demos / videos / newsletters / posters / text messages / forums) to communicate information to users, b) Gathering user’s feedback, by asking users to provide information about their opinion or specific ideas or initiatives, as part of the application optimization process, c) Lead users’ engagement in testing, which encouraged the involvement of users in planning specific actions and influencing decisions. This included one-off, specifically focused events, working groups, focus groups, workshops, questionnaires and interviews. In implementing the aforementioned approach the team of ImproveMyCity has developed a number of early demos that were communicated to the end-users (together with a survey questionnaire) through the official portal of the Municipality. Subsequently, the end users were asked to get familiarized with the version.0 of the application, interact with the demos and complete the questionnaire. At the end of the procedure, all end user groups were familiarized with the demos and they were able to proceed to the evaluation of the applications via the questionnaire. At this point, the development team of ImproveMyCity, taking into consideration the results of the questionnaire, the observations and remarks from lead users and their own experience and opinion; proceeded to the addition of new features and improved the functionality of the initial version, leading to version.1 of the application. This marked the completion of the first innovation cycle. Successive innovation cycles continued to take place as initially designed, until the ImproveMyCity platform reached its final form.

Figure 1: User involvement strategy for successive open innovation cycles.

 

Showcase

A demo installation of ImproveMyCity has been setup to lively demonstrate the features of the application. You can navigate through a set of fictionary issues in order to get in touch with the application workflow and functionality. See the application running, submit issues through the Android or the iPhone App and watch them appear in the demo installation.

Figure 5: Demo installation.

Highlights & Future Plans

The ImproveMyCity platform was originally deployed in the Municipality of Thermi, Greece in April 2012. One year later more than 500 users were registered, generating more than 585 issues and 1350 comments. Since its official release as an open source software, ImproveMyCity has been viewed more than 15000 times and downloaded more than 3800 times. Based on our current records (June 2014) there are more than 35 intallations (active & pilot) around the globe. Although the idea of engaging citizens into a two-way dialogue with their administration for improving their urban space has been around for some time, e.g. FixMyStreetSeeClickFix, BuitenBeter, ImproveMyCity is the first integrated solution that is made available as open source and covers the full-chain of information flow, ranging from the desktop user that reports issues from the leisure of his home and the mobile citizen that reports issues while on the move, all the way to the back-end management system for administering the incoming issues and the reports with aggregated statistics for performance assessment and future planning of resources. Moreover, characterized by its simple installation process, its extensive customization options and its minimum requirements in terms of additional hardware or external software libraries, ImproveMyCity is ideal for municipalities that don’t want to invest many resources until they are convinced about the benefits of citizen-government collaboration for urban maintenance and improvement. Our future plans include the extension of the existing back-end infrastructure for administering the incoming issues, with a sophisticated ticketing system that will allow for dynamic responsibility allocation and close progress monitoring. On the mobile side, our next step will be towards becoming more integrated with social media by allowing users to login with their social accounts and share their ImproveMyCity-related activity with their friends.

This acronym change is the result of a discussion within the journal’s Editorial Board, within SIGMM and between the ACM SIGMM Executive Committee and the Editorial Board. It is a process which started already in the year 2011.

Two reasons have led to the final decision: 1.) Many scientists, authors and readers have been telling us that the acronym “TOMCCAP” is somehow strange; it does not imply the journal’s focus on Multimedia research, it is too long and complicated; it sounds too specialized for a leading journal which highlights all aspects of Multimedia research. 2.) With this name change we want to emphasize the strong and long lasting collaboration with the ACM Multimedia conference (ACM MM) which we plan to further increase in the future.
