TL;DR
EventNet v1.1 is an improved large-scale video dataset with verified labels, reduced user bias, and expanded videos per event, supporting advanced event classification research.
Contribution
This paper introduces EventNet version 1.1 with verified labels, bias reduction, and expanded data, along with a CNN-based event classification model.
Findings
EventNet v1.1 contains 67,641 videos, 500 events, and 5,028 concepts.
A CNN model fine-tuned on EventNet achieves effective event classification.
EventNet v1.1 will be publicly available for research use.
Abstract
EventNet is a large-scale video corpus and event ontology consisting of 500 events associated with event-specific concepts. In order to improve the quality of the current EventNet, we conduct the following steps and introduce EventNet version 1.1: (1) manually verify the correctness of event labels for all videos; (2) remove the YouTube user bias by limiting the maximum number of videos in each event from the same YouTube user as 3; (3) remove the videos which are currently not accessible online; (4) remove the video belonging to multiple event categories. After the above procedure, some events may contain only a small number of videos, and therefore we crawl more videos for those events to ensure every event will contain more than 50 videos. Finally, EventNet version 1.1 contains 67,641 videos, 500 events, and 5,028 event-specific concepts. In addition, we train a Convolutional Neural…
