A set of 28,000 combinations of 6 Word2Vec and support vector machine parameters were considered in order to evaluate how positively would affect the inclusion of a RAE's dictionary definitions classification performance. We found that such a corpus extension significantly improve the classification accuracy. Therefore, we conclude that the inclusion of a RAE's dictionary increases the semantic relations learned by Word2Vec allowing a better classification accuracy.<\/jats:p>","DOI":"10.4114\/intartif.vol21iss62pp1-12","type":"journal-article","created":{"date-parts":[[2018,9,7]],"date-time":"2018-09-07T12:21:53Z","timestamp":1536322913000},"page":"1-12","source":"Crossref","is-referenced-by-count":4,"title":["Sentiment polarity classification of tweets using a extended dictionary"],"prefix":"10.4114","volume":"21","author":[{"given":"Jorge E.","family":"Camargo","sequence":"first","affiliation":[]},{"given":"Vladimir","family":"Vargas-Calderon","sequence":"additional","affiliation":[]},{"given":"Nelson","family":"Vargas","sequence":"additional","affiliation":[]},{"given":"Liliana","family":"Calder\u00f3n-Benavides","sequence":"additional","affiliation":[]}],"member":"2598","published-online":{"date-parts":[[2018,9,7]]},"container-title":["Inteligencia Artificial"],"original-title":[],"link":[{"URL":"http:\/\/journal.iberamia.org\/index.php\/intartif\/article\/download\/116\/67","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journal.iberamia.org\/index.php\/intartif\/article\/download\/116\/67","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,4,12]],"date-time":"2021-04-12T17:19:02Z","timestamp":1618247942000},"score":1,"resource":{"primary":{"URL":"http:\/\/journal.iberamia.org\/index.php\/intartif\/article\/view\/116"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,7]]},"references-count":0,"journal-issue":{"issue":"62","published-online":{"date-parts":[[2018,12,31]]}},"URL":"https:\/\/doi.org\/10.4114\/intartif.vol21iss62pp1-12","relation":{},"ISSN":["1988-3064","1137-3601"],"issn-type":[{"value":"1988-3064","type":"electronic"},{"value":"1137-3601","type":"print"}],"subject":[],"published":{"date-parts":[[2018,9,7]]}}}
