### Dataset Summary

The Something-Something dataset (version 2) is a collection of 220,847 labeled video clips of humans performing pre-defined, basic actions with everyday objects. It is designed to train machine learning models in fine-grained understanding of human hand gestures like putting something into something, turning something upside down and covering something with something.

### Supported Tasks and Leaderboards

- `action-recognition`: The goal of this task is to classify actions happening in a video. This is a multilabel classification. The leaderboard is available [here](https://paperswithcode.com/sota/action-recognition-in-videos-on-something)


### Languages

The annotations in the dataset are in English.

## Dataset Creation

### Curation Rationale

From the paper:
> Neural networks trained on datasets such as ImageNet have led to major advances 
in visual object classification. One obstacle that prevents networks from reasoning more 
deeply about complex scenes and situations, and from integrating visual knowledge with natural language, 
like humans do, is their lack of common sense knowledge about the physical world. 
Videos, unlike still images, contain a wealth of detailed information about the physical world. 
However, most labelled video datasets represent high-level concepts rather than detailed physical aspects 
about actions and scenes. In this work, we describe our ongoing collection of the 
“something-something” database of video prediction tasks whose solutions require a common sense 
understanding of the depicted situation


### Source Data

#### Initial Data Collection and Normalization
From the paper:
> As outlined is Section 3 videos available online are largely unsuitable for the goal of learning 
simple (but finegrained) visual concepts. We therefore ask crowd-workers to provide videos 
given labels instead of the other way around.

#### Who are the source language producers?

The dataset authors

### Annotations

#### Annotation process

The label is given first and then the video is collected by an AMT worker. More fine-grained details on the process are in the Section 4 of the work.

#### Who are the annotators?
AMT workers

### Personal and Sensitive Information
Nothing specifically discussed in the paper.

## Considerations for Using the Data

### Social Impact of Dataset

The dataset is useful for action recognition pretraining due to diverse set of actions that happen in it.
