SemEval-2010 Shared Task #14: Word Sense Induction
The primary aim of this shared task is to allow comparison of
unsupervised word sense induction and disambiguation systems.
Despite recent progress in unsupervised word sense induction (WSI) much
remains to be done before unsupervised word sense induction systems
approach the quality of manually constructed thesauri such as WordNet.
The ultimate goal of WSI systems is fully automated thesaurus
construction from unannotated data.
Previous evaluations of WSI systems has been problematic as these were
too sensitive to sense granularity. In addition, past evaluations
allowed external resources such as use of web for additional data
collection making like-for-like comparison between different WSI systems
Participants will be given a list of nouns and verbs for which word
senses need to be learnt.
For each word (noun or verb), participants will be given a training set
consisting of a collection of sentences/paragraphs.
Participating systems will be required to learn the senses of each word
(noun or verb) using the training set.
After the training phase is completed, participants will be sent a
The testing set will consist, for the same noun (and verb) given during
training, a set of sentence/paragraphs.
Participants are required to tag each sentence/paragraph containing the
target noun (and verb) with one of its induced senses.
The evaluation setting for this task is described in:
