This paper presents the work done in designing a Support Vector Machine (SVM) based Paraphrase Recognizer and then improving its performance using feature selection strategy. Wrapper method of feature selection has been adopted by combining Genetic Algorithms with Support Vector Machine Classifiers. Experimental results show that applying Feature selection improves the accuracy besides reducing the number of features. The developed paraphrase recognizer has been applied for the Student Answer Evaluation task. The results obtained show that the performance of Answer Evaluation systems which use only half the number of features is comparable to systems using the original feature set. <\/jats:p>","DOI":"10.1142\/s0218213013500073","type":"journal-article","created":{"date-parts":[[2013,1,18]],"date-time":"2013-01-18T06:06:11Z","timestamp":1358489171000},"page":"1350007","source":"Crossref","is-referenced-by-count":4,"title":["GENETIC ALGORITHM BASED FEATURE SELECTION FOR PARAPHRASE RECOGNITION"],"prefix":"10.1142","volume":"22","author":[{"given":"A.","family":"CHITRA","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, PSG College of Technology, Coimbatore, Tamil Nadu, 641004, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ANUPRIYA","family":"RAJKUMAR","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Dr. Mahalingam College of Engineering and Technology, Pollachi, Tamil Nadu, 642003, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2013,4,18]]},"reference":[{"key":"p_4","doi-asserted-by":"crossref","first-page":"135","DOI":"10.1613\/jair.2985","volume":"38","author":"Androutsopoulos I.","year":"2010","journal-title":"J. of Artificial Intelligence Research"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.1016\/j.tcs.2004.12.030"},{"issue":"9","key":"p_8","first-page":"12","volume":"33","author":"Chitra A.","year":"2009","journal-title":"CSI Communications"},{"key":"p_10","first-page":"468","author":"Das D.","year":"2009","journal-title":"Singapore"},{"key":"p_11","first-page":"9","author":"Dolan A.","year":"2005","journal-title":"Korea"},{"key":"p_12","first-page":"350","author":"Dolan A.","year":"2004","journal-title":"Switzerland"},{"key":"p_14","first-page":"17","author":"Finch A.","year":"2005","journal-title":"Korea"},{"key":"p_15","first-page":"1222","author":"Guthrie A.","year":"2006","journal-title":"Italy"},{"key":"p_16","first-page":"1011","author":"Heilman M.","year":"2010","journal-title":"California"},{"key":"p_17","first-page":"419","volume":"4177","author":"Herrera J.","year":"2006","journal-title":"Lecture Notes in Artificial Intelligence"},{"key":"p_18","first-page":"28","author":"Jarmulak J.","year":"1999","journal-title":"Sweden"},{"key":"p_19","first-page":"19","author":"Jiang J.","year":"1997","journal-title":"Taiwan"},{"key":"p_20","first-page":"53","author":"Kanejiya A.","year":"2003","journal-title":"Canada"},{"key":"p_22","first-page":"524","author":"Kozareva Z.","year":"2006","journal-title":"Finland"},{"key":"p_24","first-page":"27","author":"Malakasiotis P.","year":"2009","journal-title":"Singapore"},{"key":"p_26","first-page":"775","author":"Mihalcea R.","year":"2006","journal-title":"Boston"},{"key":"p_27","first-page":"567","author":"Mohler M.","year":"2009","journal-title":"Greece"},{"key":"p_28","first-page":"752","author":"Mohler M.","year":"2011","journal-title":"Portland"},{"key":"p_29","doi-asserted-by":"publisher","DOI":"10.1017\/S135132490999012X"},{"key":"p_31","first-page":"18","author":"Qiu L.","year":"2006","journal-title":"Australia"},{"key":"p_33","first-page":"44","author":"Schmid H.","year":"1994","journal-title":"UK"},{"key":"p_35","first-page":"290","author":"Sukkarieh J.
