Assuming that the linguistic data of a polysemous word is classified to equivalent classes according to the number of its senses, we try to disambiguate them by using a hierarchical mixture of experts' probabilistic model \u2014 a soft version of neural networks that permits overlapping between classes and which is successfully applied in classification tasks. The model is used in combination with an effective feature selection strategy based on a Chi-square test that enhances disambiguation performance. Due to the absence of previous similar work on Greek linguistic data, for comparison we also implement and apply the very popular na\u00efve Bayes classifier to the same data. Comparing the two systems, we find that the Hierarchical Mixtures-of-Experts (HME) model is superior to the na\u00efve Bayes classifier, mainly because of its ability to permit overlapping and the capture of non-linearity among the data. We believe that the system can be successfully applied on real linguistic data after training on a small amount of data. <\/jats:p>","DOI":"10.1142\/s0218213008004102","type":"journal-article","created":{"date-parts":[[2008,9,2]],"date-time":"2008-09-02T07:01:05Z","timestamp":1220338865000},"page":"687-701","source":"Crossref","is-referenced-by-count":1,"title":["DISAMBIGUATION OF GREEK POLYSEMOUS WORDS USING HIERARCHICAL PROBABILISTIC NETWORKS AND A CHI-SQUARE FEATURE SELECTION STRATEGY"],"prefix":"10.1142","volume":"17","author":[{"given":"KOSTAS","family":"FRAGOS","sequence":"first","affiliation":[{"name":"Department of Electrical Computer Engineering, NTUA, Zografou, Athens, 15780, Greece"}]},{"given":"SPIROS","family":"PANETSOS","sequence":"additional","affiliation":[{"name":"Higher School of Pedagogical &amp; Technological Education, Athens 12141, Neo Iraklio, Greece"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","volume":"26","author":"Gale W.","journal-title":"Computers and Humanities"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1991.3.1.79"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1994.6.2.181"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1991.3.1.79"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1142\/S0129065795000251"},{"key":"rf11","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-76153-9_28"},{"key":"rf13","doi-asserted-by":"publisher","DOI":"10.1007\/BF00136984"},{"key":"rf18","volume":"26","author":"Gale W.","journal-title":"Computers and Humanities"},{"key":"rf27","author":"Karov Y.","journal-title":"Association for Computational Linguistics"},{"key":"rf28","volume-title":"Wordnet: An Electronic Lexical Database","author":"Leacock C.","year":"1998"},{"key":"rf31","author":"Mihalcea R.","journal-title":"American Association for Artificial Intelligence"},{"key":"rf37","first-page":"249","volume":"22","author":"Carletta J.","journal-title":"Computational Linguistics"}],"container-title":["International Journal on Artificial Intelligence Tools"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218213008004102","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T22:28:35Z","timestamp":1565130515000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218213008004102"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,8]]},"references-count":12,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[2008,8]]}},"alternative-id":["10.1142\/S0218213008004102"],"URL":"https:\/\/doi.org\/10.1142\/s0218213008004102","relation":{},"ISSN":["0218-2130","1793-6349"],"issn-type":[{"value":"0218-2130","type":"print"},{"value":"1793-6349","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,8]]}}}
