Network data mining has a large number of applications in many disciplines including protein-protein interaction networks, social networks, transportation networks, and telecommunication networks. Different empirical studies have shown that it is possible to predict new relationships between elements attending to the topology of the network and the properties of its elements. The problem of predicting new relationships in networks is called link prediction. Link prediction aims to infer the behavior of the network link formation process by predicting missed or future relationships based on currently observed connections. It has become an attractive area of study since it allows us to predict how networks will evolve. In this survey, we will review the general-purpose techniques at the heart of the link prediction problem, which can be complemented by domain-specific heuristic methods in practice.<\/jats:p>","DOI":"10.1145\/3012704","type":"journal-article","created":{"date-parts":[[2016,12,20]],"date-time":"2016-12-20T13:25:27Z","timestamp":1482240327000},"page":"1-33","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":492,"title":["A Survey of Link Prediction in Complex Networks"],"prefix":"10.1145","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0560-8096","authenticated-orcid":false,"given":"V\u00edctor","family":"Mart\u00ednez","sequence":"first","affiliation":[{"name":"University of Granada, Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Berzal","sequence":"additional","affiliation":[{"name":"University of Granada, Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan-Carlos","family":"Cubero","sequence":"additional","affiliation":[{"name":"University of Granada, Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2016,12,20]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-8733(03)00009-1"},{"key":"e_1_2_1_2_1","volume-title":"Proceedings of the Workshop on Link Analysis, Counter-terrorism and Security (SDM\u201906)","author":"Hasan Mohammad Al","year":"2006","unstructured":"Mohammad Al Hasan , Vineet Chaoji , Saeed Salem , and Mohammed Zaki . 2006 .
