to the user\u2019s personalized characteristics. Most of the characteristics are presented in the form of high-level context. But it often lacks methods to obtain high-level context information directly in the Internet of Things. In this paper, so as to achieve the corresponding high-level context information using the specific low-level multidomain context directly obtained by different sensors in the Internet of Things, we present a machine learning method to construct a context fusion model based on the feature selection algorithm and the multiclassification algorithm. First, we propose a wrapper feature selection method based on the genetic algorithm to obtain a simpler and more important subset of the context features from the low-level multidomain context, by defining a suitable fitness function and a convergence condition. Then, we use the decision tree algorithm which is a multiclassification algorithm, based on the rules obtained by training the subset of context features, to determine which high-level context the record set of the low-level context information belongs to. Experiments confirm that the model can be used to achieve higher classification accuracy without more significant time consumption.<\/jats:p>","DOI":"10.1155\/2017\/6274824","type":"journal-article","created":{"date-parts":[[2017,11,13]],"date-time":"2017-11-13T18:35:31Z","timestamp":1510598131000},"page":"1-8","source":"Crossref","is-referenced-by-count":8,"title":["The Fusion Model of Multidomain Context Information for the Internet of Things"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3294-6303","authenticated-orcid":true,"given":"Bing","family":"Jia","sequence":"first","affiliation":[{"name":"College of Computer Science, Inner Mongolia University, Hohhot, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9909-0664","authenticated-orcid":true,"given":"Shuai","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Computer Science, Inner Mongolia University, Hohhot, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yushuai","family":"Guan","sequence":"additional","affiliation":[{"name":"College of Computer Science, Inner Mongolia University, Hohhot, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2489-3651","authenticated-orcid":true,"given":"Wuyungerile","family":"Li","sequence":"additional","affiliation":[{"name":"College of Computer Science, Inner Mongolia University, Hohhot, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiwu","family":"Ren","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Changchun University of Science and Technology, Changchun, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2015.11.024"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s12652-015-0262-2"},{"key":"3","year":"2013"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/65.313011"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-34980-0"},{"key":"12","year":"2011"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2017.1601185"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2017.04.042"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2010.05.010"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2011.5741144"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/mprv.2010.87"},{"issue":"4","key":"20","first-page":"24","volume":"71","year":"2004","journal-title":"Oki Technical Review"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.3166\/ria.19.439-458"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1016\/s0097-8493(99)00120-x"},{"issue":"8","key":"24","first-page":"1542","volume":"25","year":"2004","journal-title":"Journal of Chinese Mini-Micro Computer Systems"},{"issue":"4","key":"25","first-page":"356","volume":"2","year":"2008","journal-title":"Journal of Frontiers of Computer Science and Technology"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1109\/JSYST.2015.2460747"},{"issue":"5","key":"27","first-page":"1648","volume":"27","year":"2010","journal-title":"Application Research of Computers"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.22385\/jctecs.v8i0.96"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.22436\/jnsa.010.03.24"},{"issue":"10","key":"33","first-page":"80","volume":"16","year":"2006","journal-title":"Computer Technology and Development"},{"key":"34","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2014.09.057"},{"key":"36","first-page":"25","year":"2017","journal-title":"Journal of Marine Science Technology"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2017\/6274824.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2017\/6274824.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2017\/6274824.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,11,13]],"date-time":"2017-11-13T18:35:36Z","timestamp":1510598136000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2017\/6274824\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":23,"alternative-id":["6274824","6274824"],"URL":"https:\/\/doi.org\/10.1155\/2017\/6274824","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"value":"1530-8669","type":"print"},{"value":"1530-8677","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
