Study on user preferences modelling based on web mining
Hongwei Wang, Yu Liu, Pei Yin - · International Journal of Information Technology and Management · 2012
In view of the needs of e-commerce website for recommendation system, user interest is divided into long-term interest and short-term interest, furthermore, based on long-term interest and short-term interest, a way to describe user’s preferences is proposed. Utilising the data from the web server database, using unsupervised learning, user’s registration information can be fully mined to abstract user’s long-term interest. Based on vector mapping, both the records data and content data on the server log is analysed to abstract user’s short-term interest. Moreover, the rough profile presenting user’s preferences can be modified by dealing with user’s feedback, making updating user’s preferences profile possible. Case analysis illustrates that to a certain extent this method is reasonable and feasible.
