A Web Document Personalization User Model and System
نویسندگان
چکیده
In this paper, we present PVA, an adaptive personal view information agent system to track, learn and manage user interests in the Internet documents. PVA consists of three parts: proxy, personal view constructor and personal view maintainer. Proxy logs user’s activities and extracts user interests without user intervention. Personal view constructor mines user interests and maps them to a class hierarchy (i.e. personal view). Personal view maintainer synchronizes user interests and personal view periodically. When user interests change, PVA, not only the contents but also the structure of user profile, is modified to adapt the changes. Experimental results show that modulating the structure of user profile does increase the accuracy of personalization systems.

RRLUFF: Ranking function based on Reinforcement Learning using User Feedback and Web Document Features
Principal aim of a search engine is to provide the sorted results according to user’s requirements. To achieve this aim, it employs ranking methods to rank the web documents based on their significance and relevance to user query. The novelty of this paper is to provide user feedback-based ranking algorithm using reinforcement learning. The proposed algorithm is called RRLUFF, in which the rank...
متن کاملWeb pages ranking algorithm based on reinforcement learning and user feedback
The main challenge of a search engine is ranking web documents to provide the best response to a user`s query. Despite the huge number of the extracted results for user`s query, only a small number of the first results are examined by users; therefore, the insertion of the related results in the first ranks is of great importance. In this paper, a ranking algorithm based on the reinforcement le...

متن کاملA personalized search using a semantic distance measure in a graph-based ranking model
The goal of search personalization is to tailor search results to individual users by taking into account their profiles, which include their particular interests and preferences. As these latter are multiple and changing over time, personalization becomes effective when the search process takes into account the current user interest. This paper presents a search personalization approach that m...
