Ontologies evolve continuously during their life cycle to adapt to new requirements and needs, especially in the biomedical field, where the number of ontologies and their complexity have increased during the last years. On the other hand, a vast amount of clinical knowledge resides in natural language texts. For these reasons, building and maintaining biomedical ontologies from natural language texts is a relevant and challenging issue. In order to provide a general solution and to minimize the experts' participation during the ontology enriching process, a methodology for extracting terms and relations from natural language texts is proposed in this work. This framework is based on linguistic and statistical methods and semantic role labeling technologies, having been validated in the domain of diabetes, where they have obtained encouraging results with an F-measure of 82.1% and 79.9% for concepts and relations, respectively.<\/jats:p>","DOI":"10.4018\/jitr.2017100104","type":"journal-article","created":{"date-parts":[[2017,8,23]],"date-time":"2017-08-23T08:51:39Z","timestamp":1503478299000},"page":"56-69","source":"Crossref","is-referenced-by-count":3,"title":["Knowledge Acquisition Through Ontologies from Medical Natural Language Texts"],"prefix":"10.4018","volume":"10","author":[{"given":"Jos\u00e9","family":"Medina-Moreira","sequence":"first","affiliation":[{"name":"University of Guayaquil, Guayaquil, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katty","family":"Lagos-Ortiz","sequence":"additional","affiliation":[{"name":"University of Guayaquil, Guayaquil, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harry","family":"Luna-Aveiga","sequence":"additional","affiliation":[{"name":"University of Guayaquil, Guayaquil, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar","family":"Apolinario-Arzube","sequence":"additional","affiliation":[{"name":"University of Guayaquil, Guayaquil, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda del Pilar","family":"Salas-Z\u00e1rate","sequence":"additional","affiliation":[{"name":"University of Murcia, Department of Informatics and Systems, Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael","family":"Valencia-Garc\u00eda","sequence":"additional","affiliation":[{"name":"University of Murcia, Department of Informatics and Systems, Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"JITR.2017100104-0","doi-asserted-by":"publisher","DOI":"10.1007\/3-7908-1624-8_68"},{"key":"JITR.2017100104-1","author":"S.Ananiadou","year":"2006","journal-title":"Text Mining for Biology and Biomedicine"},{"key":"JITR.2017100104-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aei.2016.05.002"},{"key":"JITR.2017100104-3","doi-asserted-by":"publisher","DOI":"10.1007\/s00170-012-4496-2"},{"key":"JITR.2017100104-4","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2014.09.016"},{"issue":"4","key":"JITR.2017100104-5","first-page":"329","article-title":"How to manage spatio-temporal events in relational databases.","volume":"43","author":"D.Cuadra","year":"2011","journal-title":"Journal of Research and Practice in Information Technology"},{"key":"JITR.2017100104-6","unstructured":"Cunningham, et al.
