WUML: A Web Usage Manipulation Language for Querying Web Log Data
In this paper, we develop a novel Web Usage Manipulation Language (WUML) which is a declarative language for manipulating Web log data. We assume that a set of trails formed by users during the navigation process can be identified from Web log files. The trails are dually modelled as a transition graph and a navigation matrix with respect to the underlying Web topology. A WUML expression is executed by transforming it into Navigation Log Algebra (NLA), which consists of the sum, union, difference, intersection, projection, selection, power and grouping operators. As real navigation matrices are sparse, we perform a range of experiments to study the impact of using different matrix storage schemes on the performance of the NLA.
