Datasets
  • Interestingness10K - The dataset is designed for the task of predicting multimedia interestingness in images and videos, corresponding with the different editions of the MediaEval Predicting Media Interestingness task. Data consists of movie excerpts and key-frames and their corresponding ground-truth files based on the classification into interesting and non-interesting samples, along with a set of pre-processed descriptors. A thourough analysis of this dataset, MediaEval participant methods and feature performance analysis, performance enhancement suggestions and much more can be found in this IJCV paper.
  • VSD96 - The dataset is designed for the task of detecting violent events in movies and web videos, and is delivered in several packages, corresponding with the different editions of the MediaEval Affect Task - Violent Scenes Detection benchmarking campaign. Each video comes with ground-truth annotations, pre-extracted visual features and concept annotations. A thorough analysis of this dataset, MediaEval participant methods and features performance analysis and much more can be found in this TAffC paper.
  • Predicting Media Memorability 2019 - The dataset is designed for the task of predicting media memorability, and it was validated during the 2019 Predicting Media Memorability Tasks at the MediaEval Benchmarking Initiative for Multimedia Evaluation. It consists of 10000 short videos, split between a 8000-video devset and a 2000-video testset. Each video comes with a set of visual features and titles than can be interpreted as textual features.
  • MMTF-14K - The MMTF-14K dataset provides a stable and extensive source for devising and evaluating movie recommender systems. MMTF-14K contains audio and visual descriptors in addition to ratings and metadata for 13,623 Hollywood-type movie trailers. The dataset therefore facilitates research on content-based recommender systems, where content refers not only to metadata, but specifically to visual and auditory characteristics of movies. The data comes also with several baselines benchmarking results for uni-modal and multi-modal recommendation systems.
