Although manual information extraction often produces the best results, it is harder to manage biomedical data extraction manually because of the exponential increase in data size. Thus, there is a need for automatic tools and techniques for information extraction in biomedical text mining. Relation extraction is a significant area under biomedical information extraction that has gained much importance in the last two decades. A lot of work has been done on biomedical relation extraction focusing on rule-based and machine learning techniques. In the last decade, the focus has changed to hybrid approaches showing better results. This research presents a hybrid feature set for classification of relations between biomedical entities. The main contribution of this research is done in the semantic feature set where verb phrases are ranked using Unified Medical Language System (UMLS) and a ranking algorithm. Support Vector Machine and Na\u00efve Bayes, the two effective machine learning techniques, are used to classify these relations. Our approach has been validated on the standard biomedical text corpus obtained from MEDLINE 2001. Conclusively, it can be articulated that our framework outperforms all state-of-the-art approaches used for relation extraction on the same corpus.<\/jats:p>","DOI":"10.1155\/2015\/910423","type":"journal-article","created":{"date-parts":[[2015,8,10]],"date-time":"2015-08-10T17:08:43Z","timestamp":1439226523000},"page":"1-12","source":"Crossref","is-referenced-by-count":34,"title":["A Relation Extraction Framework for Biomedical Text Using Hybrid Feature Set"],"prefix":"10.1155","volume":"2015","author":[{"given":"Abdul Wahab","family":"Muzaffar","sequence":"first","affiliation":[{"name":"National University of Sciences and Technology (NUST), H-12, Islamabad 44000, Pakistan"}]},{"given":"Farooque","family":"Azam","sequence":"additional","affiliation":[{"name":"National University of Sciences and Technology (NUST), H-12, Islamabad 44000, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2361-2061","authenticated-orcid":true,"given":"Usman","family":"Qamar","sequence":"additional","affiliation":[{"name":"National University of Sciences and Technology (NUST), H-12, Islamabad 44000, Pakistan"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1038\/nrg1768"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tibtech.2006.10.002"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2009.09.001"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1093\/bib\/bbm045"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth.1284"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.drudis.2006.02.011"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2007.11.008"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2105-9-52"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1186\/1747-5333-3-1"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.2217\/pgs.10.136"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/btr155"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/btl203"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/17.2.155"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/btk016"},{"key":"18","first-page":"401","volume":"18","year":"2006","journal-title":"EACL"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmedinf.2005.06.010"},{"key":"22","series-title":"Lecture Notes in Computer Science","doi-asserted-by":"crossref","first-page":"139","DOI":"10.1007\/978-3-642-19437-5_11","volume-title":"A hybrid approach for the extraction of semantic relations from medline abstracts","volume":"6609","year":"2011"},{"key":"23","first-page":"S4","volume":"2","year":"2011","journal-title":"Journal of Biomedical Semantics"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-22913-8_10"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.12720\/jiii.1.3.169-173"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pcbi.1002854"},{"key":"28","year":"2011"},{"key":"33","series-title":"Technical Report CS\u201400\u201410","year":"2000"},{"key":"37","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2105-11-107"},{"key":"38","doi-asserted-by":"publisher","DOI":"10.1007\/BFb0026683"},{"key":"39","doi-asserted-by":"publisher","DOI":"10.1145\/1961189.1961199"},{"key":"41","doi-asserted-by":"publisher","DOI":"10.1109\/72.991427"},{"issue":"9","key":"43","doi-asserted-by":"crossref","first-page":"1264","DOI":"10.1109\/TKDE.2008.76","volume":"20","year":"2008","journal-title":"IEEE Transactions on Knowledge and Data Engineering"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2015\/910423.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2015\/910423.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2015\/910423.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,23]],"date-time":"2017-06-23T13:21:27Z","timestamp":1498224087000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2015\/910423\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":28,"alternative-id":["910423","910423"],"URL":"https:\/\/doi.org\/10.1155\/2015\/910423","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"value":"1748-670X","type":"print"},{"value":"1748-6718","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
