Social network is a web-based platform which enables people to share information, make new connections and explore various events that occur in society. In social networks, link prediction techniques are widely used to discover new indirect relationships that may occur in the future. These techniques are also utilized to effectively detect missing links in any monitored network. This study presents a concise review of the similarity measures, techniques employed in predicting future links and application of link prediction with emphasis on dynamic networks. An analysis of available models for link prediction and their suitability for heterogeneous, large, static or dynamic networks is also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
