# ActivityNet Entities dataset | |||
This repo hosts the dataset used in our paper [Grounded Video Description](https://arxiv.org/abs/1812.06587). | |||
|
|||
ActivityNet-Entities, is based on the video description dataset [ActivityNet Captions](https://cs.stanford.edu/people/ranjaykrishna/densevid/) and augments it with 158k bounding box annotations, each grounding a noun phrase (NP). Here we release the complete set of NP-based annotations as well as the pre-processed object-based annotations. | |||
|
|||
<img src='demo/dataset_teaser.png' alt="dataset teaser" width="80%"/> | |||
|
|||
### Data | |||
We have the following dataset files under the `data` directory: | |||
|
|||
- `anet_entities_trainval.json`: The raw dataset file with noun phrase and bounding box annotations. We only release the training and the validation splits for now. | |||
|
|||
- `anet_entities_cleaned_class_thresh50_trainval.json`: Pre-processed dataset file with object class and bounding box annotations. For training and validation splits only. | |||
|
|||
- `anet_entities_skeleton.txt`: Specify the expected structure of the JSON annotation files. | |||
|
|||
- `split_ids_anet_entities.json`: Video IDs included in the training/validation/testing splits. | |||
|
|||
- `anet_entities_cleaned_class_thresh50_test_skeleton.json`: Object class annotation for the testing split. This file is for evaluation server purpose and the bounding box annotation is not given. See below for more details. | |||
|
|||
Note: Both the raw dataset file and the pre-processed dataset file contains all the 12469 videos in the original training and validation splits (as in ActivityNet Captions, which is based on [ActivityNet 1.3](http://activity-net.org/download.html)). This includes 626 videos without box annotations. | |||
|
|||
### Evaluation | |||
Under the `scripts` directory, we include: | |||
- `attr_prep_tag_NP.py`: The preprocessing scripts to obtain the NP/object annotation files. | |||
- The scripts that print the dataset stats. | |||
- The evaluation script for object grounding. [PyTorch](https://pytorch.org/get-started/locally/) is required. To evaluate your results, run: | |||
``` | |||
python scripts/eval_grd_anet_entities.py -s YOUR_SUBMISSION_FILE.JSON | |||
``` | |||
Please follow the example in `data/anet_entities_skeleton.txt` to format your submission file. | |||
|
|||
|
|||
### Others | |||
Please contact <luozhou@umich.edu> if you have any trouble running the code. Please cite the following paper if you use the dataset. | |||
``` | |||

The noun phrases in these annotations are based on [ActivityNet Captions](https://cs.stanford.edu/people/ranjaykrishna/densevid/), which are linked to videos in [ActivityNet 1.3](http://activity-net.org/download.html) |
