Disaster Tweet Corpus 2020

This dataset consists of tweets collected during 48 disasters over 10 disaster types with human annotations denoting if a tweet is related to this disaster or not. This collection is intended as a benchmarking dataset for filtering algorithms. 

Dataset Specification

Tweets are separated into files based on individual disasters, where each file contains a balanced number of positive and negative examples. The naming scheme is as follows:

<disaster type>-<name or region>[-<sub-type>]-<year>.ndjson

Each line in the data files is a complete json-object, containing the tweet-id, the text, and the annotations as:

{"id": "12345", "text": "let's all pray for nepal!", "relevance": 1}
