Title IMSTrans
Author Anders Björkelund

Description

IMSTrans is a transition-based dependency parser. The parser implements the (labeled) ArcStandard system including a swap transition allowing for non-projective structures following Nivre (2009). It can be used to train both greedy parsers and globally optimized beam-search parsers. The parser was developed for the paper Björkelund & Nivre (2015) and implements all the non-deterministic oracles discussed in that paper. The parser was also used in the paper by Falenská et al. (2015).

The parser was further developed for the Björkelund et al. (2016) paper on joint sentence splitting and parsing.
