Improved PageRank Algorithm Based on User Interest Degree
Huang Xian-yin · 2014
Traditional PageRank algorithm had such drawbacks as theme drifting,history pages being emphasized and the user's interests in results being ignored. Facing the above defects described,an improved ranking algorithm called PRUI was proposed,which was based on user interest degree. It mainly re-estimated PR value of web page integrating objective characteristics of web page with subjective characteristics of user's interests,and ranked the web page according to the calculated PR value again. The experimental results show that PRUI algorithm has acquired higher retrieval accuracy as well as first page hit ratio,compared with traditional PageRank algorithm.
