The Web facilitates qualitative and quantitative comparisons via online debates, discussion forums, product comparison sites, etc., and<jats:italic>comparison analysis<\/jats:italic>is becoming increasingly useful in many application areas. This study develops a method for classifying sentences in Korean text documents into several different comparative types to facilitate their analysis. We divide our study into two tasks: (1) extracting comparative sentences from text documents and (2) classifying comparative sentences into seven types. In the first task, we investigate many actual comparative sentences by referring to previous studies and construct a lexicon of comparisons. Sentences that contain elements from the lexicon are regarded as comparative sentence candidates. Next, we use machine learning techniques to eliminate non-comparative sentences from the candidates. In the second task, we roughly classify the comparative sentences using keywords and use a transformation-based learning method to correct initial classification errors. Experimental results show that our method could be suitable for practical use. We obtained an F1-score of 90.23% in the first task, an accuracy of 81.67% in the second task, and an overall accuracy of 88.59% for the integrated system with both tasks.<\/jats:p>","DOI":"10.1017\/s1351324913000211","type":"journal-article","created":{"date-parts":[[2013,9,6]],"date-time":"2013-09-06T12:54:47Z","timestamp":1378472087000},"page":"557-581","source":"Crossref","is-referenced-by-count":3,"title":["Classifying Korean comparative sentences for comparison analysis"],"prefix":"10.1017","volume":"20","author":[{"given":"SEON","family":"YANG","sequence":"first","affiliation":[]},{"given":"YOUNGJOONG","family":"KO","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2013,9,9]]},"reference":[{"key":"S1351324913000211_ref024","doi-asserted-by":"publisher","DOI":"10.3115\/1119176.1119180"},{"key":"S1351324913000211_ref021","first-page":"271","volume-title":"Proceedings of the 42nd Annual Meeting of the Association for Computational Linguistics (ACL 2004)","author":"Pang","year":"2004"},{"key":"S1351324913000211_ref001","first-page":"39","article-title":"A maximum entropy approach to natural language processing","volume":"22","author":"Berger","year":"1996","journal-title":"Computational Linguistics"},{"key":"S1351324913000211_ref015","first-page":"1075","volume-title":"Proceedings of the Joint Conference on Empirical Methods in Natural Language Processing and Computational Natural Language Learning (EMNLP-CoNLL 2007)","author":"Kaji","year":"2007"},{"key":"S1351324913000211_ref020","first-page":"197","article-title":"The difference between \u2018Man-kum\u2019 comparative and \u2018Cheo-rum\u2019 comparative","volume":"14","author":"Oh","year":"2004","journal-title":"Society of Korean Semantics"},{"key":"S1351324913000211_ref008","volume-title":"Korean Modern Comparative Syntax","author":"Ha","year":"1999"},{"key":"S1351324913000211_ref017","doi-asserted-by":"publisher","DOI":"10.3115\/1220835.1220861"},{"key":"S1351324913000211_ref016","doi-asserted-by":"crossref","first-page":"355","DOI":"10.3115\/1610075.1610125","volume-title":"Proceedings of the Conference on Empirical Methods in Natural Language Processing (EMNLP 2006)","author":"Kanayama","year":"2006"},{"key":"S1351324913000211_ref002","first-page":"1","volume-title":"Proceedings of the Sixth Conference on Natural Language Learning (CoNLL-2002)","author":"Black","year":"2002"},{"key":"S1351324913000211_ref003","doi-asserted-by":"publisher","DOI":"10.3115\/974499.974526"},{"key":"S1351324913000211_ref004","first-page":"543","article-title":"Transformation-based error-driven learning and natural language processing: a case study in part-of-speech tagging","volume":"21","author":"Brill","year":"1995","journal-title":"Computational Linguistics"},{"key":"S1351324913000211_ref006","first-page":"193","volume-title":"Proceedings of","author":"Esuli","year":"2006"},{"key":"S1351324913000211_ref029","doi-asserted-by":"publisher","DOI":"10.1007\/s10579-005-7880-9"},{"key":"S1351324913000211_ref007","unstructured":"Esuli A. , and Sebastiani F. 2006b.
