TwitIE is a named entity recognition pipeline specially tuned for use with Twitter data. It performs

• tokenisation, sentence splitting and part-of-speech tagging using a model trained specifically for Tweets
• normalisation of abbreviations and shortened word forms frequently found in Tweets ("brb", "ttyl", "gr8", "2day", etc.)
• tagging of Twitter-specific entities such as hashtags and @mentions, as well as URLs and emoticons
• general named-entity recognition, to identify basic entity types such as Person, Location, Organization, Money amounts, Time and Date expressions.
