This booklet constitutes the completely refereed post-proceedings of the sixth foreign Workshop on Mining net facts, WEBKDD 2004, held in Seattle, WA, united states in August 2004 at the side of the tenth ACM SIGKDD overseas convention on wisdom Discovery and information Mining, KDD 2004.

The eleven revised complete papers provided including a close preface went via rounds of reviewing and development and have been carfully chosen for inclusion within the booklet. The prolonged papers are subdivided into four common teams: internet utilization research and consumer modeling, internet personalization and recommender structures, seek personalization, and semantic internet mining. The latter comprises additionally papers from the joint KDD workshop on Mining for and from the Semantic internet, MSW 2004.

Am , p be a dimension, which is to be filled during the ETL process. ,A is referred to as valid semantic basis for D). ,Ak be another semantic basis that fulfills {A1 , . . , A } ⊆ {A1 , . . , Ak }. ,A . The mapping T ◦ Π is denoted as ETL basis transformation for dimension D. Analogously, an ETL coordinate transformation t ◦ π can be defined. 4 Modeling the LOORDSM in UML Eventually we introduce the LOORDSM as it has been realized in WUSAN. The different classes have been modeled with respect to the Web usage analysis domain.

34 T. Maier An ETL process can be started separately for each mart provided that appropriate data sources are available. ,A , we may start an ETL process to populate the CustomerMart separately from SessionMart and TransactionMart. ,A . 6 Conclusions In this contribution we addressed the issue of modeling and deploying an ETL process in the Web usage analysis domain by introducing a logical object-oriented relational data storage model (LOORDSM). This model has been deployed within our WUSAN system, which has also been briefly summarized.

Am maps any vector a ∈ D(A1 , . . , Am ) to a one-dimensional user-defined domain P. p is called primary key mapping, since it assigns a unique primary key to any given vector in D(A1 , . . , Am ). e. ,Am (ai ), i = 1, . . , n. ,Am , p as dimension. If m = 1, D is called degenerated dimension. A dimension is based on a data matrix (for example a database table), the primary keys of which are calculated by the primary key mapping for every vector, which is inserted into the data matrix. As we will see in the next section, the primary key mapping can be used to determine a dimension’s behavior in terms of permitting or impeding vector insertions into the underlying data matrix.
