The purpose of WSD is to make computers automatically determine the specific meaning of a word in a specific context. In this regard, state-of-art studies have focussed on the co-occurrences of words to measure context similarity. However, a problem with these approaches is that they consider all the words within a certain range to have equal influence on the ambiguous word. In this paper, we propose a position-based algorithm for measuring context similarity. By assigning positional weights to context words, we compared the context similarity between a new instance and pre-labelled instances to determine the appropriate sense of the ambiguous word. Experiments on the Senseval-2 English lexical sample task showed that our algorithm can achieve good precision and recall. Even in a minimally supervised state, it performs well with few training instances.<\/jats:p>","DOI":"10.1177\/0165551512459919","type":"journal-article","created":{"date-parts":[[2012,11,20]],"date-time":"2012-11-20T22:10:20Z","timestamp":1353449420000},"page":"225-237","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Word sense disambiguation based on positional weighted context"],"prefix":"10.1177","volume":"39","author":[{"given":"Shilin","family":"Huang","sequence":"first","affiliation":[{"name":"Zhejiang University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaolin","family":"Zheng","sequence":"additional","affiliation":[{"name":"Zhejiang University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haixiao","family":"Kang","sequence":"additional","affiliation":[{"name":"Zhejiang University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deren","family":"Chen","sequence":"additional","affiliation":[{"name":"Zhejiang University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,11,20]]},"reference":[{"key":"bibr1-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1145\/1459352.1459355"},{"key":"bibr2-0165551512459919","volume-title":"1988 annual meeting of the International Studies Association","author":"John CM","year":"1988"},{"key":"bibr3-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-27660-6_10"},{"key":"bibr4-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1145\/1571941.1571994"},{"key":"bibr5-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-10291-2_20"},{"key":"bibr6-0165551512459919","first-page":"111","author":"Azzini A","year":"2010","journal-title":"Artif Life Evol Comput"},{"issue":"5","key":"bibr7-0165551512459919","first-page":"2345","volume":"7","author":"Yu JP","year":"2011","journal-title":"Int J Innov Comput Inform Control"},{"key":"bibr8-0165551512459919","doi-asserted-by":"publisher","DOI":"10.3115\/981658.981684"},{"key":"bibr9-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1016\/j.ipm.2008.07.002"},{"key":"bibr10-0165551512459919","doi-asserted-by":"publisher","DOI":"10.3115\/1621474.1621528"},{"key":"bibr11-0165551512459919","first-page":"1616","volume-title":"Proceedings of 21st international joint conference on artificial intelligence (IJCAI-09)","author":"Zhong Z","year":"2009"},{"key":"bibr12-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1177\/0165551509103599"},{"key":"bibr13-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1007\/s11390-010-9385-2"},{"key":"bibr14-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1145\/318723.318728"},{"key":"bibr15-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1109\/MICAI.2009.41"},{"key":"bibr16-0165551512459919","first-page":"75","volume-title":"Proceedings of the second international workshop on evaluating word sense disambiguation systems (SENSEVAL)","author":"Fernandez-Amoros D","year":"2001"},{"key":"bibr17-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-13881-2_6"},{"key":"bibr18-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1145\/219717.219748"},{"key":"bibr19-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-15992-3_37"},{"key":"bibr20-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1109\/ICSC.2009.7"},{"key":"bibr21-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1134\/S0361768810010032"},{"key":"bibr22-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-20161-5_65"},{"key":"bibr23-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-12842-4_32"},{"key":"bibr24-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1145\/321439.321441"},{"key":"bibr25-0165551512459919","doi-asserted-by":"publisher","DOI":"10.1145\/361219.361220"},{"key":"bibr26-0165551512459919","unstructured":"Tanimoto T.
