What TweeboParser does

Given a tweet, TweeboParser predicts its syntactic structure, represented by unlabeled dependencies.Since a tweet often contains more than one utterance, the output of TweeboParser will often be a multi-rooted graph over the tweet. Also, many elements in tweets have no syntactic function. These include, in many cases, hashtags, URLs, and emoticons. TweeboParser tries to exclude thesetokens from the parse tree (grayed out in the example below).

Please refer to the paper for more information.
