Mate tools is a toolkit of statistical NLP tools comprising a lemmatizer, part-of-speech tagger, morphological tagger, dependency parser, and semantic role labeler. It includes two different dependency parsers, a graph-based parser [1], and a joint tagger and transition-based parser [2]. The semantic role labeler is described in [3]. The complete pipeline and its web interface is described in [4]. Sources, binaries, and pre-trained models for several languages are available at
