Overview of Open Dataset Sessions and Benchmarking Competitions in 2023–2024 - Part 2 (MDRE at MMM 2023 and MMM 2024)

As already started in the previous Datasets column, we are reviewing some of the most notable events related to open datasets and benchmarking competitions in the field of multimedia in the years 2023 and 2024. This 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. This year's review follows similar efforts from the previous year (https://records.sigmm.org/records-issues/acm-sigmm-records-issue-1-2023/), highlighting the ongoing importance of open datasets and benchmarking competitions in advancing research and development in multimedia. This second part of the column focuses on the last two editions of MDRE at MMM 2023 and MMM 2024: • Multimedia Datasets for Repeatable Experimentation at 29th International Conference on Multimedia Modeling (MDRE at MMM 2023). We summarize the seven datasets presented during the MDRE in 2023, namely NCKU-VTF (thermal-to-visible face recognition benchmark), Link-Rot (web dataset decay and reproducibility study), People@Places and ToDY (scene classification for media production), ScopeSense (lifelogging dataset for health analysis), OceanFish (high-resolution fish species recognition), GIGO (urban garbage classification and demographics), and Marine Video Kit (underwater video retrieval and analysis). • Multimedia Datasets for Repeatable Experimentation at 30th International Conference on Multimedia Modeling (MDRE at MMM 2024 - https://mmm2024.org/). We summarize the eight datasets presented during the MDRE in 2024, namely RESET (video similarity annotations for embeddings), DocCT (content-aware document image classification), Rach3 (multimodal data for piano rehearsal analysis), WikiMuTe (semantic music descriptions from Wikipedia), PDTW150K (large-scale patent drawing retrieval dataset), Lifelog QA (question answering for lifelog retrieval), Laparoscopic Events (event recognition in surgery videos), and GreenScreen (social media dataset for greenwashing detection).
