We used topic modelling based on latent Dirichlet allocation analysis to identify underlying topics in sub-areas in the field. We also used social network analysis to measure the centrality indices of publication keywords to detect important and influential sub-areas and used co-occurrence analysis of keywords to visualise relationships among subfields. The research result is useful to identify evolving topics and areas of current focus in the field of humanoid technology. The results contribute to identify valuable research patterns from publications and to increase understanding of the hidden knowledge themes that are revealed by patents.<\/jats:p>","DOI":"10.1177\/0165551519887878","type":"journal-article","created":{"date-parts":[[2019,12,9]],"date-time":"2019-12-09T07:43:50Z","timestamp":1575877430000},"page":"658-676","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":38,"title":["Topic modelling and social network analysis of publications and patents in humanoid robot technology"],"prefix":"10.1177","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9074-0595","authenticated-orcid":false,"given":"Richa","family":"Kumari","sequence":"first","affiliation":[{"name":"Department of Science and Technology Management Policy, University of Science and Technology, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Yun","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Science and Technology Management Policy, University of Science and Technology, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byeong-Hee","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Science and Technology Management Policy, University of Science and Technology, South Korea; NTIS Center, Korea Institute of Science and Technology Information, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kwang-Nam","family":"Choi","sequence":"additional","affiliation":[{"name":"NTIS Center, Korea Institute of Science and Technology Information, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiseok","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Science and Technology Management Policy, University of Science and Technology, South Korea; NTIS Center, Korea Institute of Science and Technology Information, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,12,9]]},"reference":[{"key":"bibr1-0165551519887878","doi-asserted-by":"crossref","unstructured":"Asada M, MacDorman KF, Ishiguro H et al.
