In this Dataset Column, we present a review of some of the notable events related to open datasets and benchmarking competitions in the field of multimedia. This year’s selection highlights the wide range of topics and datasets currently of interest to the community. Some of the events covered in this review include special sessions on open datasets and competitions featuring multimedia data. While this list is not exhaustive and contains an overview of about 40 datasets, it is meant to showcase the diversity of subjects and datasets explored in the field. This year’s review follows similar efforts from the previous year (https://records.sigmm.org/2022/01/12/overview-of-open-dataset-sessions-and-benchmarking-competitions-in-2021/), highlighting the ongoing importance of open datasets and benchmarking competitions in advancing research and development in multimedia. The column is divided into three parts, in this one we focus on MDRE at MMM 2022 and ACM MM 2022:

ACM MM 2022

Numerous dataset-related papers have been presented at the 30th ACM International Conference on Multimedia (MM’ 22), organized in Lisbon, Portugal, October 10 – 14, 2022 (https://2022.acmmm.org/). The complete MM ’22: Proceedings of the 30th ACM International Conference on Multimedia are available in the ACM Digital Library (https://dl.acm.org/doi/proceedings/10.1145/3503161).

There was not a specifically dedicated Dataset session among roughly 35 sessions at the MM ’22 symposium. However, the importance of datasets can be illustrated in the following statistics, quantifying how often the term “dataset” appears in MM ’22 Proceedings. The term appears in the title of 9 papers (7 last year), the keywords of 35 papers (66 last year), and the abstracts of 438 papers (339 last year). As a small example, nine selected papers focused primarily on new datasets with publicly available data are listed below. There are contributions focused on various multimedia applications, e.g., understanding multimedia content, multimodal fusion and embeddings, media interpretation, vision and language, engaging users with multimedia, emotional and social signals, interactions and Quality of Experience, and multimedia search and recommendation.

We summarize three datasets included in this conference, that address QoE studies on audiovisual 360° video, storytelling for quality perception and energy consumption while streaming video QoE.
• Open Dataset and Software Track at 13th ACM Multimedia Systems Conference (ODS at MMSys ’22 – https://mmsys2022.ie/). We summarize nine datasets presented at the ODS track, targeting several topics, including surveillance videos from a fishing vessel (Njord), multi-codec 8K UHD videos (8K MPEG-DASH dataset), light-field (LF) synthetic immersive large-volume plenoptic dataset (SILVR), a dataset of online news items and the related task of rematching (NewsImages), video sequences, characterized by various complexity categories (VCD), QoE dataset of realistic video clips for real networks, dataset of 360° videos with subjective emotional ratings (PEM360), free-viewpoint video dataset, and cloud gaming dataset (CGD).

For the overview of datasets related to MDRE at MMM 2022 and ACM MM 2022 please check the second part (http://records.sigmm.org/?p=12360), while ImageCLEF 2022 and MediaEval 2022 are addressed in the third part (http://records.sigmm.org/?p=12362).

QoMEX 2022

Three dataset papers were presented at the International Conference on Quality of Multimedia Experience (QoMEX 2022), organized in Lippstadt, Germany, September 5 – 7, 2022 (https://qomex2022.itec.aau.at/). The complete QoMEX ’22 Proceeding is available in the IEEE Digital Library (https://ieeexplore.ieee.org/xpl/conhome/9900491/proceeding).

These datasets were presented within the Databases session, chaired by Professor Oliver Hohlfeld. These three papers present contributions focused on audiovisual 360-degree videos, storytelling for quality perception and modelling of energy consumption and streaming of video QoE.

Dataset available at: https://qoevave.github.io/database/

This publicly available database provides audiovisual 360° content with high-order Ambisonics audio. It consists of twelve scenes capturing real-life nature and urban environments with a video resolution of 7680×3840 at 60 frames-per-second and with 4th-order Ambisonics audio. These 360° video sequences, with an average duration of 60 seconds, represent real-life settings for systematically evaluating various dimensions of uni-/multi-modal perception, cognition, behavior, and QoE. It provides high-quality reference material with a balanced focus on auditory and visual sensory information.

Dataset available at: https://osf.io/cyb8w/

This is a dataset of simulated videotelephony clips to act as stimuli in quality perception research. It consists of four different stories in the German language that are told through ten consecutive parts, each about 10 seconds long. Each of these parts is available in four different quality levels, ranging from perfect to stalling. All clips (FullHD, H.264 / AAC) are actual recordings from end-user video-conference software to ensure ecological validity and realism of quality degradation. Apart from a detailed description of the methodological approach, we contribute the entire stimuli dataset containing 160 videos and all rating scores for each file.

Dataset available at: On request

This paper performs a first analysis of end-user power efficiency and Quality of Experience of a video streaming service. A crowdsourced dataset comprising 447,000 streaming events from YouTube is used to estimate both the power consumption and perceived quality. The power consumption is modelled based on previous work, which extends toward predicting the power usage of different devices and codecs. The user-perceived QoE is estimated using a standardized model.
