Previous research mainly focuses on network characteristics measurement and community evolution, but it remains largely understudied on how to uncover research topics of each community. This paper proposes a nonjoint approach, consisting of three simple steps: (1) to detect overlapping academic communities in SCN with the clique percolation method, (2) to discover underlying topics and research interests of each researcher with author-topic (AT) model, and (3) to label research topics of each community with top N most frequent collaborative topics between members belonging to the community. Extensive experimental results on NIPS (neural information processing systems) dataset show that our simple procedure is feasible and efficient. <\/jats:p>","DOI":"10.1155\/2014\/529842","type":"journal-article","created":{"date-parts":[[2014,4,27]],"date-time":"2014-04-27T21:02:32Z","timestamp":1398632552000},"page":"529842","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Uncovering Research Topics of Academic Communities of Scientific Collaboration Network"],"prefix":"10.1177","volume":"10","author":[{"given":"Hongqi","family":"Han","sequence":"first","affiliation":[{"name":"Institute of Scientific and Technical Information of China, Beijing 100038, China"}]},{"given":"Shuo","family":"Xu","sequence":"additional","affiliation":[{"name":"Institute of Scientific and Technical Information of China, Beijing 100038, China"}]},{"given":"Jie","family":"Gui","sequence":"additional","affiliation":[{"name":"Institute of Scientific and Technical Information of China, Beijing 100038, China"}]},{"given":"Xiaodong","family":"Qiao","sequence":"additional","affiliation":[{"name":"Institute of Scientific and Technical Information of China, Beijing 100038, China"}]},{"given":"Lijun","family":"Zhu","sequence":"additional","affiliation":[{"name":"Institute of Scientific and Technical Information of China, Beijing 100038, China"}]},{"given":"Han","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Scientific and Technical Information of China, Beijing 100038, China"}]}],"member":"179","published-online":{"date-parts":[[2014,4,27]]},"reference":[{"key":"B1-2014-529842","doi-asserted-by":"publisher","DOI":"10.1016\/j.dss.2012.09.012"},{"key":"B2-2014-529842","doi-asserted-by":"publisher","DOI":"10.1016\/j.joi.2012.09.005"},{"key":"B3-2014-529842","author":"Brunson J.
