基于序列模式的网站导航系统

互联网已经成为公众获取信息的重要来源.然而,随着网站规模扩大和日趋复杂,获取相关信息越来越难.解决这些问题的途径之一,就是采用网站导航系统,利用以往访问者留下的信息给新访问者推荐网页.从系统设计的角度,综合考虑了导航系统的效果和效率,提出了一个离线-在线的系统结构,并设计了带有推荐表单的树形数据结构来提高系统的可扩展性.使用来源于互联网上真实网站的数据,实验结果表明,该系统能为网站的早期访问者提供较满意的推荐.

Website Navigation Support Systems based on Sequential Patterns

Websites become important sources of information.However,with the scale growing larger and structure getting more complicated,it is even harder to get relevant information.One way dealing with the issue is to use website navigation system,which leverages the access information of past visits to help new visits.From system design perspective,this paper proposes an offline-online system architecture that takes into account both efficiency and effectiveness of website navigation system.A tree structure with recommendation lists is proposed to improve system extendibility.The experimental results on an Internet website prove that the system can offer satisfied service for new visits to the hosting sites.
