We study an important network feature called node popularity, which is closely associated with community structure. Neither the classical stochastic block model nor its degree-corrected extension can satisfactorily capture the dynamics of node popularity as observed in empirical networks. We propose a popularity-adjusted block model for flexible and realistic modelling of node popularity. We establish consistency of likelihood modularity for community detection as well as estimation of node popularities and model parameters, and demonstrate the advantages of the new modularity over the degree-corrected block model modularity in simulations. By analysing the political blogs network, the British Members of Parliament network and the \u2018Digital bibliography and library project\u2019 bibliographical network, we illustrate that improved empirical insights can be gained through this methodology.<\/jats:p>","DOI":"10.1111\/rssb.12245","type":"journal-article","created":{"date-parts":[[2017,8,24]],"date-time":"2017-08-24T06:14:03Z","timestamp":1503555243000},"page":"365-386","source":"Crossref","is-referenced-by-count":50,"title":["A Block Model for Node Popularity in Networks with Community Structure"],"prefix":"10.1093","volume":"80","author":[{"given":"Srijan","family":"Sengupta","sequence":"first","affiliation":[{"name":"Virginia Tech , Blacksburg , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuguo","family":"Chen","sequence":"additional","affiliation":[{"name":"University of Illinois , Urbana\u2013Champaign , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2017,8,24]]},"reference":[{"key":"2023022101105178400_","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1145\/1134271.1134277","article-title":"The political blogosphere and the 2004 US election: divided they blog","volume-title":"Proc. 3rd Int.
