TVR: A Large-Scale Dataset for Video-Subtitle Moment Retrieval
Table 14: TVC split info.
['Split', '#desc.', '#moments', '#videos', '#desc./moment']
To promote better coverage of the video (subtitle) content, we encourage annotators to write descriptions that are of different types from existing ones, e.g., we encourage annotators to write video-only and video-text type descriptions if there already exists a text-only description. For each moment in the TVR training set, we collect one extra description, together with the original description forms the TVC training set with 2 descriptions for each moment. For each moment in TVR val/test sets, we collect 4 extra descriptions as the TVC val/test sets. The original val/test descriptions in TVR are not used to ensure data integrity. TVC follows the same data split as the TVR, but with different number of descriptions per moment, i.e., the training moments are paired with 2 descriptions while the moments in other splits are paired with 4 descriptions. The rules on split usage are also the same as the TVR.
