Usually, some complex dataset is modeled as a graph and a technique for detecting outliers in graphs is applied. The impact of the graph model on the outlier detection capabilities of any method has been ignored. Here we assess the impact of the graph model on the outlier detection performance and the gains that may be achieved by using multiple graph models and combining the results obtained by these models. We show that assessing the similarity between graphs may be a guidance to determine effective combinations, as less similar graphs are complementary with respect to outlier information they provide and lead to better outlier detection.<\/jats:p>","DOI":"10.2298\/csis181001010c","type":"journal-article","created":{"date-parts":[[2019,6,11]],"date-time":"2019-06-11T11:48:27Z","timestamp":1560253707000},"page":"565-595","source":"Crossref","is-referenced-by-count":6,"title":["Outlier detection in graphs: A study on the impact of multiple graph models"],"prefix":"10.2298","volume":"16","author":[{"suffix":"Oliveira","given":"Guilherme","family":"Campos","sequence":"first","affiliation":[{"name":"Federal University of Minas Gerais Belo Horizonte, Minas Gerais, Brazil + University of Southern Denmark, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edr\u00e9","family":"Moreira","sequence":"additional","affiliation":[{"name":"Federal University of Minas Gerais Belo Horizonte, Minas Gerais, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"Wagner","family":"Meira","sequence":"additional","affiliation":[{"name":"Federal University of Minas Gerais Belo Horizonte, Minas Gerais, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arthur","family":"Zimek","sequence":"additional","affiliation":[{"name":"University of Southern Denmark, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1078","container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:33:48Z","timestamp":1685349228000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02141900010C"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2019]]}},"URL":"https:\/\/doi.org\/10.2298\/csis181001010c","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019]]}}}
