Semi-automatic support may reduce the time needed for the detection of such situations, generating early warnings that can prevent accidents or provide time to prepare countermeasures. In order to provide adequate cognitive support for operators and guide the design of more efficient surveillance systems, this paper investigates the human analytical reasoning process of detecting anomalous behavior through a case study, the surveillance of sea areas. The analysis of data gathered during interviews and participant observations at three maritime control centers and the inspection of video recordings of real incidents lead to a characterization of operators' analytical processes. We suggest how to support these processes using data mining and visualization, and we derive recommendations for designers and developers of future maritime control systems.<\/jats:p>","DOI":"10.1142\/s021962201450045x","type":"journal-article","created":{"date-parts":[[2014,1,8]],"date-time":"2014-01-08T07:41:37Z","timestamp":1389166897000},"page":"317-360","source":"Crossref","is-referenced-by-count":3,"title":["Detecting anomalous behavior in sea traffic: A study of analytical strategies and their implications for surveillance systems"],"prefix":"10.1142","volume":"13","author":[{"given":"Maria","family":"Riveiro","sequence":"first","affiliation":[{"name":"Informatics Research Centre, University of Sk\u00f6vde, Box 408, SE-541 31, Sk\u00f6vde, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00f6ran","family":"Falkman","sequence":"additional","affiliation":[{"name":"Informatics Research Centre, University of Sk\u00f6vde, Box 408, SE-541 31, Sk\u00f6vde, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2014,3,31]]},"reference":[{"key":"rf2","first-page":"119","volume":"11","author":"Cai Y.","journal-title":"Journal of Knowledge and Information Systems"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1142\/S0219622006002258"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1142\/S0219622008003204"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1201\/9781420043426"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1007\/s12198-007-0007-3"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1016\/j.apergo.2006.10.004"},{"key":"rf11","doi-asserted-by":"publisher","DOI":"10.1016\/j.apm.2005.12.009"},{"key":"rf13","doi-asserted-by":"publisher","DOI":"10.1142\/S0219622004001057"},{"key":"rf14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2008.10.025"},{"key":"rf15","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-1286(98)00017-6"},{"key":"rf16","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2007.02.001"},{"key":"rf17","doi-asserted-by":"publisher","DOI":"10.1145\/1541880.1541882"},{"key":"rf22","doi-asserted-by":"crossref","first-page":"2137","DOI":"10.1093\/clinchem\/47.12.2137","volume":"47","author":"Horn P.
