. .. . The Optique Project 2 / 6 Optique Architecture

. .. . The Optique Project 2 / 6 Optique Architecture: WP6

. .. . What: development, implementation, and evaluation of the Optique query transformation system. How: Make use of optimized ontology and mapping layers: 1. Design of optimized ontology and mappings. 2. Adaptation based on requirement changes. 3. Tuning based on execution feedback. Who: FUB (66 PMs), UNIROMA1 (16 PMs), UOXF.BL (12 PMs), U.o.A (12 PMs) The Optique Project 3 / 6 WP6 : Query Transformation

. .. . Design, implementation, and testing of a collection of techniques for: query transformation system. over the data sources. system in response to changes in The Optique Project 4 / 6 WP6 : Objectives . (Semi-)automatic configuration of the various levels of the . Automatic efficient rewriting of end-user queries into queries . Tuning the different components of the query transformation . the ontology and mapping layers, . the query load, and . the data source configuration.
