A Framework for Warehousing the Web Contents
نویسنده
چکیده
This paper presents a framework for warehousing selected Web contents. In this framework, a hybrid (partially materialized) approach and extended ontologies are used to achieve Web data integration. This hybrid approach makes it possible to integrate DW data with Web-based information resources as they are needed. The Ontologies are used to represent domain knowledge related to Web sources and the logic model of data warehouses. Moreover, we define the mapping rules between Web data and attributes of data warehouses in the ontologies to facilitate the construction and maintenance requirements of data warehouses.
