Abstract: TOPHITS algorithm is the development of HITS algorithm, it shows the link structure with a 3-dimensional vector. In citation graph, people usually needs to consider the type of link, and classify different link types, and then find the community structure in the graph. This research combine the literature citation graph with the collaboration graph, constitute a new citation graph which contains relationship of collaboration, and then apply TOPHITS algorithm to detect the community structure in the new citation graph. We have carried on the experimental demonstration based on PubMed database, and proved that TOPHITS algorithm has a certain role in identifying the community structure in typed link.
