One approach for sentiment extraction is using a sentiment lexicon. A sentiment lexicon is a set of words associated with the sentiment orientation that they express. In this paper, we describe the process of generating a general purpose sentiment lexicon for Persian. A new graph-based method is introduced for seed selection and expansion based on an ontology. Sentiment lexicon generation is then mapped to a document classification problem. We used the K-nearest neighbors and nearest centroid methods for classification. These classifiers have been evaluated based on a set of hand labeled synsets. The final sentiment lexicon has been generated by the best classifier. The results show an acceptable performance in terms of accuracy and F-measure in the generated sentiment lexicon.<\/jats:p>","DOI":"10.29007\/f4j4","type":"proceedings-article","created":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T18:04:22Z","timestamp":1516730662000},"page":"329-317","source":"Crossref","is-referenced-by-count":9,"title":["LexiPers: An ontology based sentiment lexicon for Persian"],"prefix":"10.29007","volume":"41","author":[{"given":"Behnam","family":"Sabeti","sequence":"first","affiliation":[]},{"given":"Pedram","family":"Hosseini","sequence":"additional","affiliation":[]},{"given":"Gholamreza","family":"Ghassem-Sani","sequence":"additional","affiliation":[]},{"given":"S\u064eeyed Abolghasem","family":"Mirroshandel","sequence":"additional","affiliation":[]}],"member":"11545","event":{"name":"GCAI 2016. 2nd Global Conference on Artificial Intelligence"},"container-title":["EPiC Series in Computing"],"original-title":[],"deposited":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T18:04:23Z","timestamp":1516730663000},"score":1,"resource":{"primary":{"URL":"https:\/\/easychair.org\/publications\/paper\/q2F"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[null]]},"references-count":0,"URL":"https:\/\/doi.org\/10.29007\/f4j4","relation":{},"ISSN":["2398-7340"],"issn-type":[{"value":"2398-7340","type":"print"}],"subject":[]}}
