| Because of the rapid development of E-commerce, more and more enterprises build up their websites, some websites are used for showing their information, and some websites are used for trading. Navigation structure is an important factor that influence website. How to improve and optimize the navigation structure becomes a very concerned research topic.On the basic analysis of many literatures in navigation structures optimize method, this research compared previous navigation optimize method and model using a framework which combined factors about website navigation structures, objective of users, navigation strategy. User navigation model is comprised by the value of factors about objective of users and user strategy which can predict users'navigation activity. In order to find the best user navigation model, the model is divided into three sub model that are navigation path model, navigation time model, and objective model. We can find best navigation path model through compare the real path in website log files with the path predicted by path model, find best navigation time model and objective model through compare the real navigation time with the time predicted by the other two models. Now that we find the 3 sub models, then we can get best user navigation model. Meanwhile, based on the idea of Ant Colony System (ACS), a preliminary algorithm of website structure optimization model is given. At the end of this paper, we indicates the shortcomings of the study and research topic that can study in future. |
