Most NMF-based community detection methods only utilize the first-order proximity information in the adjacency matrix, which has some limitations. Besides, many NMF-based community detection methods involve sparse regularizations to promote clearer community memberships. However, in most of these regularizations, different nodes are treated equally, which seems unreasonable. To dismiss the above limitations, this article proposes a community detection method based on node centrality under the framework of NMF. Specifically, we design a new similarity measure which considers the proximity of higher-order neighbors to form a more informative graph regularization mechanism, so as to better refine the detected communities. Besides, we introduce the node centrality and\n            <jats:italic>Gini<\/jats:italic>\n            impurity to measure the importance of nodes and sparseness of the community memberships, respectively. Then, we propose a novel sparse regularization mechanism which forces nodes with higher node centrality to have smaller\n            <jats:italic>Gini<\/jats:italic>\n            impurity. Extensive experimental results on a variety of real-world networks show the superior performance of the proposed method over thirteen state-of-the-art methods.\n          <\/jats:p>","DOI":"10.1145\/3578520","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T12:09:49Z","timestamp":1672142989000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["Nonnegative Matrix Factorization Based on Node Centrality for Community Detection"],"prefix":"10.1145","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6140-447X","authenticated-orcid":false,"given":"Sixing","family":"Su","sequence":"first","affiliation":[{"name":"Department of Automation, Xiamen University, China and Xiamen Key Laboratory of Big Data Intelligent Analysis and Decision-Making, Xiamen, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2765-9302","authenticated-orcid":false,"given":"Jiewen","family":"Guan","sequence":"additional","affiliation":[{"name":"Department of Automation, Xiamen University, China and Xiamen Key Laboratory of Big Data Intelligent Analysis and Decision-Making, Xiamen, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5805-072X","authenticated-orcid":false,"given":"Bilian","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Automation, Xiamen University, China and Xiamen Key Laboratory of Big Data Intelligent Analysis and Decision-Making, Xiamen, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3650-0301","authenticated-orcid":false,"given":"Xin","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Hong Kong Baptist University, Hong Kong, China"}]}],"member":"320","published-online":{"date-parts":[[2023,2,28]]},"reference":[{"issue":"3","key":"e_1_3_2_2_2","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1016\/S0378-8733(03)00009-1","article-title":"Friends and neighbors on the web","volume":"25","author":"Adamic Lada A.","year":"2003","unstructured":"Lada A.
