Abstract

The typical content-based recommendation systems make use of textual similarity between items. Based on the knowledge about historical user behaviours extracted from the web logs, the content recommendation lists can be verified and filtered: some items are reinforced whereas some other are weakened. Four different usage patterns are used in the filtering process: positive and negative association rules, positive sequential patterns and negative sequential patterns. The last ones are the new pattern concept introduced in the paper.
