_DESCRIPTION = """\
|
18 |
-
The ActivityNet Captions dataset connects videos to a series of temporally annotated sentence descriptions.
|
19 |
-
Each sentence covers an unique segment of the video, describing multiple events that occur. These events
|
20 |
-
may occur over very long or short periods of time and are not limited in any capacity, allowing them to
|
21 |
-
co-occur. On average, each of the 20k videos contains 3.65 temporally localized sentences, resulting in
|
22 |
-
a total of 100k sentences. We find that the number of sentences per video follows a relatively normal
|
23 |
-
distribution. Furthermore, as the video duration increases, the number of sentences also increases.
|
24 |
-
Each sentence has an average length of 13.48 words, which is also normally distributed. You can find more
|
25 |
-
details of the dataset under the ActivityNet Captions Dataset section, and under supplementary materials
|
26 |
-
in the paper.
