To address this gap, this article aims to (1) develop a measurement model for physicians\u2019 knowledge contribution performance; (2) use BP neural network to assign reasonable weight to each indicator of the model; and (3) explore the status and differences of knowledge contribution performance among a group of physicians. Based on the sample of 5407 infectious disease physicians in a Chinese OHC, we propose the measurement model by integrating physicians\u2019 active knowledge contribution (AKC) and responsive knowledge contribution (RKC), covering 11 dimensions of contribution quantity and quality. We employ the BP neural network to optimise the model weights using the initial weight of the model obtained by the entropy method. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method is used to evaluate the performance of physicians\u2019 knowledge contribution in the OHC. The results show that it is feasible to use BP neural network to assign model weights. The distribution of physicians\u2019 knowledge contribution performance is uneven; only a few have a high-level knowledge contribution performance. Meanwhile, a significant positive correlation exists between a physician\u2019s title and respective knowledge contribution performance. Our research may contribute to related literature and practices by offering a fine-grained understanding of the performance of physicians\u2019 knowledge contribution.<\/jats:p>","DOI":"10.1177\/01655515221121946","type":"journal-article","created":{"date-parts":[[2022,9,6]],"date-time":"2022-09-06T05:37:47Z","timestamp":1662442667000},"page":"1382-1399","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Measuring knowledge contribution performance of physicians in online health communities: A BP neural network approach"],"prefix":"10.1177","volume":"50","author":[{"given":"Sudi","family":"Xia","sequence":"first","affiliation":[{"name":"School of Information Management, Wuhan University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijian","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information Management, Wuhan University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5166-3141","authenticated-orcid":false,"given":"Shaoxiong","family":"Fu","sequence":"additional","affiliation":[{"name":"College of Information Management, Nanjing Agricultural University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1741-0674","authenticated-orcid":false,"given":"Xiaoyu","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Cultural Heritage and Information Management, Shanghai University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,9,6]]},"reference":[{"key":"bibr1-01655515221121946","doi-asserted-by":"publisher","DOI":"10.2196\/16704"},{"key":"bibr2-01655515221121946","doi-asserted-by":"publisher","DOI":"10.1016\/j.elerap.2015.04.001"},{"key":"bibr3-01655515221121946","doi-asserted-by":"publisher","DOI":"10.1016\/j.ipm.2020.102253"},{"key":"bibr4-01655515221121946","unstructured":"China Council for the Promotion of International Trade.
