In this paper, we investigate the conditions under which link analysis algorithms prevent minority groups from reaching high ranking slots. We find that the most common link-based algorithms using centrality metrics, such as PageRank and HITS, can ...

Social networks can represent many different types of relationships between actors, some explicit and some implicit. For example, email communications between users may be represented explicitly in a network, while managerial relationships may not. In ...

Several assistive applications exhibit a network structure. Characterizing the structure of such networks is critical in many assistive applications. Existing methods in the of social network analysis aim to detect, analyze, and summarize interesting or ...

Link analysis ranking methods are widely used for summarizing the connectivity structure of large networks. We explore a weighted version of two common link analysis ranking algorithms, PageRank and HITS, and study their applicability to assistive ...

Relevance is a numerical score assigned to a search result, representing how well the results meet the information needs of the user that issued the search query. Several mathematical tools and techniques have been used in research for improving the ...
