Questions are posted and answered by community members. These users, who can help other users answer questions, can be considered experts. To facilitate finding a suitable expert and alleviate information overload, in this paper, expert yellow pages (EYP) for community question answering (CQA) are constructed. Considering the various lengths of texts, the biterm topic model (BTM) is used to model questions and fields of expertise. Then, two\u2010dimensional EYP (2DEYP), which are composed of expertise field dimensions and question dimensions, are constructed. The intersections represent the cluster of experts. The proposed 2DEYP can be expanded both laterally and vertically for a more in\u2010depth understanding and a more precise location. As the closer neurons represent similar topics, a novel labelling method is proposed to identify topic words for navigation. The method uses the distance between neurons as the differentiation capability. To further distinguish experts, a ranking mechanism is proposed. The experts can be ranked by integrating their expertise and activity levels. The expertise level is novel and characterized by both breadth and depth aspects. The proposed approach is evaluated via a real dataset, and the experimental results show that the proposed algorithm is feasible and performs well.<\/jats:p>","DOI":"10.1111\/exsy.12684","type":"journal-article","created":{"date-parts":[[2021,4,14]],"date-time":"2021-04-14T02:47:19Z","timestamp":1618368439000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An approach for constructing expert yellow pages for community question answering sites"],"prefix":"10.1111","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3966-255X","authenticated-orcid":false,"given":"Ming","family":"Li","sequence":"first","affiliation":[{"name":"School of Economics and Management China University of Petroleum\u2010Beijing  Beijing China"}]},{"given":"Xiaoyu","family":"Qi","sequence":"additional","affiliation":[{"name":"School of Economics and Management China University of Petroleum\u2010Beijing  Beijing China"}]},{"given":"Ying","family":"Li","sequence":"additional","affiliation":[{"name":"School of Economics and Management China University of Petroleum\u2010Beijing  Beijing China"}]},{"given":"Xiuzhi","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Economics and Management China University of Petroleum\u2010Beijing  Beijing China"}]},{"given":"Li","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Economics and Management Beihang University  Beijing China"}]}],"member":"311","published-online":{"date-parts":[[2021,4,13]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"Abdi H.(n.d.).The Kendall rank correlation coefficient."},{"key":"e_1_2_9_3_1","first-page":"34","article-title":"The impact of knowledge behavioural factors on tacit knowledge retention: Empirical study in oil and gas industry","volume":"2019","author":"Abdullah Gaghman A.","year":"2020","journal-title":"KnE Social Sciences"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0306-4573(02)00021-3"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jom.2009.10.003"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.respol.2013.10.009"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijdrr.2018.10.005"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.im.2018.03.011"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.respol.2007.08.005"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02332159"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.analchem.0c00986"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dss.2014.02.001"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/2971565"},{"volume-title":"IOP conference series: Materials science and engineering","year":"2020","author":"Ilham A.
