In this paper, we extend two different Dirichlet multinomial topic models by incorporating latent feature vector representations of words trained on very large corpora to improve the word-topic mapping learnt on a smaller corpus. Experimental results show that by using information from the external corpora, our new models produce significant improvements on topic coherence, document clustering and document classification tasks, especially on datasets with few or short documents. <\/jats:p>","DOI":"10.1162\/tacl_a_00140","type":"journal-article","created":{"date-parts":[[2018,12,28]],"date-time":"2018-12-28T15:44:35Z","timestamp":1546011875000},"page":"299-313","source":"Crossref","is-referenced-by-count":214,"title":["Improving Topic Models with Latent Feature Word                     Representations"],"prefix":"10.1162","volume":"3","author":[{"given":"Dat Quoc","family":"Nguyen","sequence":"first","affiliation":[{"name":"Department of Computing, Macquarie University, Sydney, Australia,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Billingsley","sequence":"additional","affiliation":[{"name":"Department of Computing, Macquarie University, Sydney, Australia,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lan","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Computing, Macquarie University, Sydney, Australia,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Johnson","sequence":"additional","affiliation":[{"name":"Department of Computing, Macquarie University, Sydney,                         Australia"},{"name":"Santa Fe Institute, Santa Fe, New Mexico, USA,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"key":"p_2","first-page":"993","volume":"3","author":"Blei David M.","year":"2003","journal-title":"Journal of Machine Learning Research"},{"issue":"4","key":"p_3","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1145\/2133806.2133826","volume":"55","author":"Blei David M.","year":"2012","journal-title":"Communications of the ACM"},{"issue":"3","key":"p_4","doi-asserted-by":"crossref","first-page":"510","DOI":"10.3758\/BF03193020","volume":"39","author":"Bullinaria John A.","year":"2007","journal-title":"Behavior Research Methods"},{"key":"p_8","first-page":"288","author":"Chang Jonathan","year":"2009","journal-title":"Advances in Neural Information Processing Systems 22, pages"},{"issue":"6","key":"p_10","doi-asserted-by":"crossref","first-page":"391","DOI":"10.1002\/(SICI)1097-4571(199009)41:6<391::AID-ASI1>3.0.CO;2-9","volume":"41","author":"Deerwester Scott","year":"1990","journal-title":"Journal of the American Society for Information Science"},{"key":"p_13","doi-asserted-by":"crossref","first-page":"5228","DOI":"10.1073\/pnas.0307752101","volume":"101","author":"Griffiths Thomas L.","year":"2004","journal-title":"Proceedings of the National Academy of Sciences of the United States of America"},{"issue":"1","key":"p_14","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1145\/1656274.1656278","volume":"11","author":"Hall Mark","year":"2009","journal-title":"ACM SIGKDD Explorations Newsletter"},{"issue":"2","key":"p_20","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1023\/A:1007665907178","volume":"37","author":"Jordan Michael I.","year":"1999","journal-title":"Machine Learning"},{"key":"p_21","first-page":"897","author":"Lacoste-Julien Simon","year":"2009","journal-title":"Advances in Neural Information Processing Systems 21, pages"},{"issue":"3","key":"p_23","doi-asserted-by":"crossref","first-page":"503","DOI":"10.1007\/BF01589116","volume":"45","author":"Liu D.
