Abstract:

Bipartite graph of queries and concept is insufficient in concept grabbing and calculating weight of the query words, which cause the user interest model construction not reasonable. The improved bipartite graph of queries and concept will represent the users query intent more accurate by using tf×idf grasping concepts and calculating the weight of query query words through user's browsing time. A user interest modeling algorithm based on improved bipartite graph of queries and concept was proposed. And experiments verified that user interest model constructed by this algorithm is more reasonable.

Key words: bipartite graph of queries and concept, browsing time, user interest model (UIM)
