Super Sense Tagging (SST)

Super-sense tagging (SST) is a Natural Language Processing task that consists of annotating each significant entity in a text, like nouns, verbs, adjectives and adverbs, within a general semantic taxonomy defined by the WordNet lexicographer classes (called super-senses). SST can be considered as a task half-way between Named-Entity Recognition (NER) and Word Sense Disambiguation (WSD): it is an extension of NER, since it uses a larger set of semantic categories, and it is an easier and more practical task with respect to WSD, that deals with very specific senses.

Closed subtask In the closed subtask, we want to measure the accuracy in SS tagging, when only the corpus provided for training is used.

Open subtask In the open subtask participants will be free to use any external resource in addition to the corpus provided for training; for example, instances of WordNet as well as other lexical or semantic resources.

Task materials A corpus for Super-sense tagging was created starting from the Italian Syntactic-Semantic Treebank (ISST) by a semi-automatic correction and conversion process, followed by manual revision [LREC 2010]. ISST-SST (~320,000 tokens ) is freely available for the task and for research purposes. It will be used for training and development. The test will be performed on a smaller corpus obtained from the Italian Wikipedia.
