Aletheia - Semantic Federation of Comprehensive Product Information

  • internet information retrieval
  • federated search
  • web information extraction
  • resource selection
  • meta-data based information management


In all areas of the product life cycle, significant product-specific data are created. Not only conventional sources of such information, but also internet forums, blogs, wikis, e-mail and electronic documents have to be considered. Existing product life cycle management systems do not incorporate such information sources and focus the development, production and sales life cycle. Yet they disregard the upstream stages customer requirement analysis and product portfolio management, as well as the successive operation, maintenance and recycling stages. The goal of Aletheia is to develop an overall system support architecture for such product information management. In particular, semantic techniques, highly distributed data management, and seamless internet integration are crucial issues. Based on the lifecyle- and delivery-chain-spanning management, a new dimension of global product database is created. This is of extreme value for consumers, service providers, and producers. The particular domain of TU Dresden is the design and implementation of the global system architecture. Major partners include SAP, BMW, ABB and Otto. The project is funded by BMBF and runs from March 2008 until June 2011.
Besides taking part of the development of the integrated prototype for the use cases ABB, BMW and SAP, TU Dresden develops the Fedseeko prototype for as a showcase for further innovative applications to be realized using the idea of semantic federation of product information. Fedseeko is a Ruby-on-Rails-based Web application offering the consumer a central point of truth for retrieving product information. Fedseeko aims at creating an all-embracing view on the product of desire using product information from all three mentioned information source types. Different technologies being located in the backend like Web services, information extraction (especially Web scraping), natural language processing, ontology matching or ontology learning are used for retrieving and preprocessing the information. The frontend is designed using technologies like AJAX, Javascript frameworks and RHTML. The application is based on JRuby and thus offers the possibility to include Java classes. Eventually, browser plugins are employed for displacing extraction tasks on the clients’ side.
