Abstract
We tackled the task of SuperSense tagging by means of the Tanl Tagger, a generic, flexible and customizable sequence labeler, developed as part of the Tanl linguistic pipeline. The tagger can be configured to use different classifiers and to extract features according to feature templates expressed through patterns, so that it can be adapted to different tagging tasks, including PoS and Named Entity tagging. The tagger operates in a Markov chain, using a statistical classifier to infer state transitions and dynamic programming to select the best overall sequence of tags. We exploited the extensive customization capabilities of the tagger in order to tune it for the task of SuperSense tagging, by performing an extensive process of feature selection. The resulting configuration achieved the best scores in the closed subtask.
