摘要
Trajectory similarity of moving objects resembles path similarity of user click-streams in web usage mining. By analyzing the URL path of each user, we are able to determine paths that are very similar and therefore effective caching strategies can be applied. In recent years, World Wide Web has been increasingly used by terrorists to spread their ideologies and web mining techniques have been used in cyber crime and terrorism research. Analysis of space and time of click stream data to establish web session similarity from historical web access log of dark web will give insights into access pattern of terrorism sites. This paper deals with the variations in applying spatio-temporal similarity measure of moving objects proposed by the authors in PAISI 2010, to web user session trajectories treating spatial similarity as a combination of structural and sequence similarity of web pages. A similarity set formation tool is proposed for web user session trajectories which has applications in mining click stream data for security related matters in dark web environment. The validity of the findings is illustrated by experimental evaluation using a web access log publically available.
