To make accurate recommendations, recommendation systems currently require more data about a customer than is usually available. We conjecture that the weaknesses are due to a lack of inductive bias in the learning methods used to build the prediction models.

Clustering may be partition-based or hierarchical to reveal further structure. All three forms use background knowledge / semantics to enable the clustering algorithm to form groups, but also in all three forms semantics are learned in the sense that actually existing instantiations of a particular template (here defined by the graph structure) are discovered. In Web usage mining, this learning identifies composite application events—behavioural patterns in the data [3]. 4 Time and Space Requirements Theoretical evaluation.
