-This toolkit contains tools to extract conversational features and analyze social phenomena in conversations, using a [single unified interface](https://convokit.cornell.edu/documentation/architecture.html) inspired by (and compatible with) scikit-learn.  Several large [conversational datasets](https://github.com/CornellNLP/Cornell-Conversational-Analysis-Toolkit#datasets) are included together with scripts exemplifying the use of the toolkit on these datasets. The latest version is [2.5.3](https://github.com/CornellNLP/Cornell-Conversational-Analysis-Toolkit/releases/tag/v2.5.3) (released 16 Jan 2022); follow the [project on GitHub](https://github.com/CornellNLP/Cornell-Conversational-Analysis-Toolkit) to keep track of updates.
