Paper Abstract:
|
In the context of the personalized web, the structure of user profiles remains a challenge due to its effect on information
retrieval efficiency. In creating a user profile, how to extract collections of metadata of documents is a significant point.
Although the efficiency of the structures such as keyword-based has proven, there is not research on key phrase based user
profiles in the process of personalization. Previous methods to create user profiles emphasize keyword extraction while
ignoring the existence of key phrases in the documents. This article proposes the use of keyphrase-based user profiles in
personalized web search. We investigate the state of the art keyphrase extraction algorithms by considering different models
of supervised and unsupervised methods. This can overcome the problems of missing keyphrases in user profiles and
increase the accuracy of information retrieval. Finally, we evaluate keyphrase-based user profiles using a re-ranking
algorithm to complete the process of personalization using different datasets. Personalized models based on supervised
keyphrase extraction approaches obtained more accuracy by 7% than unsupervised approaches. |
