In the system, a social network among e-learning learners is dynamically constructed on the basis of the location information of learners using GPS sensors for collaborative learning. In addition, user modeling for semantic social network and adaptive e-learning is supported. For these, a mechanism that supports the construction of a dynamic social network using the location information of smart phones is provided. The user modeling for the construction of a semantic social network and the support of adaptive e-learning considers the information such as the users' achievement, preference, and learning goal. Through this system, e-learners can find mentors who are able to facilitate their learning and create communities for collaborative learning offline and online. The support of a location-based social network service and semantic user model in our system would increase interactions among e-learners and improve satisfaction regarding their mobile learning environment. <\/jats:p>","DOI":"10.1155\/2012\/506810","type":"journal-article","created":{"date-parts":[[2012,3,22]],"date-time":"2012-03-22T15:10:34Z","timestamp":1332429034000},"page":"506810","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["An Adaptive System Supporting Collaborative Learning Based on a Location-Based Social Network and Semantic User Modeling"],"prefix":"10.1177","volume":"8","author":[{"given":"Sook-Young","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Computer Education, Woosuk University, Jeollabukdo 565-701, Republic of Korea"}]},{"given":"Jang-Mook","family":"Kang","sequence":"additional","affiliation":[{"name":"Electronic Commerce Research Institute of Dongguk University, Gyeongsangbuk-do 780-714, Republic of Korea"}]}],"member":"179","published-online":{"date-parts":[[2012,3,20]]},"reference":[{"issue":"2","key":"B2-2012-506810","first-page":"7","volume":"4","author":"Fredericksen E.","year":"2000","journal-title":"Journal of Asynchronous Learning Network"},{"key":"B9-2012-506810","doi-asserted-by":"publisher","DOI":"10.1080\/01587910500081269"},{"issue":"1","key":"B4-2012-506810","first-page":"48","volume":"9","author":"Tinto V.","year":"2000","journal-title":"Journal of Institutional Research"},{"issue":"23","key":"B1-2012-506810","first-page":"39","volume":"46","author":"Carr S.","year":"2000","journal-title":"Chronicle of Higher Education"},{"key":"B3-2012-506810","doi-asserted-by":"publisher","DOI":"10.1002\/nha3.10184"},{"key":"B11-2012-506810","first-page":"224","author":"Liccard I.","year":"2010","journal-title":"SIGCSE Bulletin"},{"key":"B6-2012-506810","doi-asserted-by":"publisher","DOI":"10.1109\/ICALT.2010.11"},{"key":"B16-2012-506810","doi-asserted-by":"publisher","DOI":"10.1109\/MDM.2009.50"},{"key":"B5-2012-506810","doi-asserted-by":"publisher","DOI":"10.1109\/IHMSC.2009.45"},{"key":"B7-2012-506810","doi-asserted-by":"publisher","DOI":"10.1109\/ESIAT.2009.484"},{"key":"B15-2012-506810","doi-asserted-by":"publisher","DOI":"10.15388\/infedu.2005.11"},{"issue":"1","key":"B14-2012-506810","first-page":"34","volume":"2","author":"Wegerif R.","year":"1998","journal-title":"Journal of ALN"},{"issue":"1","key":"B12-2012-506810","first-page":"21","volume":"5","author":"Curtis D.
