Patent ID: 7904443

Claim:
A method of computer-based detecting of guidance performance of an information driven web site for a user seeking a desired content, comprising: assigning a transition value to each click based on an effectiveness and efficiency of transition between web pages of the web site; and determining an indicator value by combining the transition values into a metric that reflects guidance performance of the web site; wherein the effectiveness of transition is measured based on web page categories that comprise navigation and content pages and transitions between the web page categories are evaluated for qualifying successful guidance of the user; wherein web page categories are determined by a web author manually or via a Hits-algorithm both assigning category values to a web page reflecting web page functionality for delivering content and allowing navigation; wherein effectiveness of transition is measured based on web page topics of content pages and transitions between the web page topics are evaluated for quantifying successful guidance of the user; wherein a degree of topic change is performed by regarding all occurring topic transitions of a currently evaluated user session and comparing them with topic transitions in focus; wherein keywords are extracted from visited web pages and clustered to identify content group building topics, a probability is calculated for each web page belonging to a content group building topic, resulting in a content group building topic vector for each web page, and a distance is calculated between all web pages based on content similarity; and wherein hierarchical clustering, k-means clustering or probabilistic latent semantic indexing by maximization of likelihood by EM-algorithm is performed.
