Using Sequential and Non-Sequential Patterns in Predictive Web Usage Mining Tasks

We describe an efficient framework for Web personalization based on sequential and non-sequential pattern discovery from usage data. Our experimental results performed on real usage data indicate that more restrictive patterns, such as contiguous sequential patterns (e.g., frequent navigational paths) are more suitable for predictive tasks, such as Web prefetching, which involve predicting which item is accessed next by a user), while less constrained patterns, such as frequent itemsets or general sequential patterns are more effective alternatives in the context of Web personalization and recommender systems.
