Title A Dependency Parser for Tweets
Venue Conference on Empirical Methods in Natural Language Processing
Session Main Conference
Year 2014

We describe a new dependency parser for English tweets, TWEEBOPARSER. The parser builds on several contributions: new syntactic annotations for a corpus of tweets (TWEEBANK), with conventions informed by the domain; adaptations to a statistical parsing algorithm; and a new approach to exploiting out-of-domain Penn Treebank data. Our experiments show that the parser achieves over 80% unlabeled attachment accuracy on our new, high-quality test set and measure the benefit of our contribu- tions. Our dataset and parser can be found at
