CrisisLex (http://CrisisLex.org/) is a repository of crisis-related social media data and tools. Currently it includes collections of crisis data and a lexicon of crisis terms. It also includes tools to help you create these collections and lexicons.

This repository contains the following sub-directories:

The directory data/ contains tweets, annotated data, and keywords used or produced during the construction of the lexicon or other analyses.

The directory src-collect/ contains scripts that can be used to collect tweets using this lexicon.

The directory src-create/ contains the scripts that can be used to create a new lexicon based on labeled tweets.
