In this respect, the Twitter search functionality is not a practical tool when we want to poll messages dealing with a given set of general topics. This article presents an approach to classify Twitter messages into various topics. We tackle the problem from a linguistic angle, taking into account part-of-speech, syntactic and semantic information, showing how language processing techniques should be adapted to deal with the informal language present in Twitter messages. The TASS 2013 General corpus, a collection of tweets that has been specifically annotated to perform text analytics tasks, is used as the dataset in our evaluation framework. We carry out a wide range of experiments to determine which kinds of linguistic information have the greatest impact on this task and how they should be combined in order to obtain the best-performing system. The results lead us to conclude that relating features by means of contextual information adds complementary knowledge over pure lexical models, making it possible to outperform them on standard metrics for multilabel classification tasks.<\/jats:p>","DOI":"10.1177\/0165551514561652","type":"journal-article","created":{"date-parts":[[2014,12,12]],"date-time":"2014-12-12T23:22:27Z","timestamp":1418426547000},"page":"127-145","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["A linguistic approach for determining the topics of Spanish Twitter messages"],"prefix":"10.1177","volume":"41","author":[{"given":"David","family":"Vilares","sequence":"first","affiliation":[{"name":"Universidade da Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel A.","family":"Alonso","sequence":"additional","affiliation":[{"name":"Universidade da Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"G\u00f3mez-Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Universidade da Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,12,12]]},"reference":[{"key":"bibr1-0165551514561652","unstructured":"Twitter Inc.
