SINAI at Robust WSD Task @ CLEF 2008: When WSD is a Good Idea for Information Retrieval tasks?

Fernando Javier Martínez Santiago, José M. Perea-Ortega, Miguel A. García-Cumbreras
2008 Conference and Labs of the Evaluation Forum  
This year we have participated in the first edition of Robust WSD task with the aim of investigating the performance of disambiguation tools applied to Information Retrieval (IR).  ...  The main interest of our experimentation is the characterization of queries where WSD is a useful tool. That is, which issues must be fulfilled by a query in order to apply an state-of-art WSD tool?  ...  Introduction Word Sense Disambiguation (WSD) is a traditional task into the discipline of Natural Language Processing (NLP).  ...

2010 Italian Information Retrieval Workshop  
We provide an in vivo evaluation in an Information Retrieval scenario and we compare the proposed method with another one which exploits Word Sense Disambiguation (WSD).  ...  Contrary to sense discrimination, which is the task of discriminating among different meanings (not necessarily known a priori), WSD is the task of selecting a sense for a word from a set of predefined  ...  EVALUATION The goal of the evaluation was to establish how Semantic Vectors influence the retrieval performance. The system is evaluated into the context of an Information Retrieval (IR) task.  ...

Enriched Page Rank for Multilingual Word Sense Disambiguation

Diego De Cao, Roberto Basili, Matteo Luciani, Francesco Mesiano, Riccardo Rossi
2011 Italian Information Retrieval Workshop  
Word Sense Disambiguation (WSD) is an hard challenge especially for language different from english.  ...  In this paper an adaptation of the PageRank algorithm proposed for WSD using distributional information is presented.  ...  In this approach we used a policy of "one sense per discourse". The Evalita '07 all-words task 3 consists of about 4700 words to disambiguate.  ...
