Indexing web access-logs for pattern queries Alexandros Nanopoulos, Yannis Manolopoulos, Maciej Zakrzewicz, and Tadeusz Morzy   View Paper (PDF)   Return to Web services and performance evaluation Abstract search for access sequences that contain certain query patterns. This kind of queries find applications in processing web-log mining results (e.g., finding typical/atypical access-sequences). The proposed method focuses on scalability to web-logs' sizes. For this reason, we examine the gains due to signature-trees, which can further improve the scalability to very large web-logs. Experimental results illustrate the superiority of the proposed method.
