2. g. [16]), under variation of the number of transactions/sessions, the branching factor b of the concepts in a one-level taxonomy (and thus the number of patterns found in a total of 100 “URLs”), the diversity of patterns (each node had a parameterized transition probability pS to one other, randomly chosen node and an equal distribution of transition probabilities to all other nodes), and the length of patterns (the transition probability pL to “exit”—average session length becomes 1/pL, and pattern length increases with it).

Results of graph clustering. Figure 3 reveals a very high number of individual patterns, an observation that was commonly made in these data: Individual patterns with frequency = 1 constituted 99% of all patterns. The reasons are the very large database behind the Web site and the highly idiosyncratic information needs of its users; they make the request for each data record (and for each set of data records) very infrequent. com) top-level group it referred to. Query mining that based the feature-space representation of patterns on URLs was used for two reasons that also apply in many other Web-server log analyses: First, to understand what visitors were looking for rather than what they obtained (often, empty result sets), and second, because URLs were much more amenable to semantic analysis than their corresponding Web pages, which often consisted of pictorial material with very heterogeneous characteristics.
