A Comprehensive Review of Similarity Based Link Prediction Methods for Complex Networks including Computational Biology

Abstract

Information retrieval is one of the most challenging tasks for the mankind and to retrieve information interaction is required, which ultimately leads to the formation of networks. Universe is packed with different type of networks. Networks with complex topological properties are called complex network. Such types of networks are major tools for learning the connection between the organizations and finding the purpose of complex systems. The link prediction problems in complex networks facilitate predictions about the future organization of the network. Network is represented as a graph. The data in the network is signified by nodes, and the relations are represented by links. The future of non-connected links amid node pairs is predicted. This paper reviews the methods used to predict links for complex networks using similarity-based heuristics. Previous reviews, despite having a clear outline of the link prediction study, only described the prediction approaches. Research gaps between the similarity-based link prediction techniques, however, were not explicitly stated. With the help of chronological findings and a research gaps approach, this review seeks to give a continuing review and introduce the link prediction.
