Efficient mining of traversal patterns
A new problem of mining traversal patterns from Web access logs is introduced. The traversal patterns are defined to keep duplicates as well as consecutive ordering in the sessions. Then an efficient algorithm is proposed. The algorithm is online, which allows the user to see the incremental results with respect to the scanned part of the database. The algorithm also adapts to large databases through dynamic compressions and effective pruning. Finally the algorithm is evaluated through experiments with real Web logs.
