WP6: Query Transformation

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)

WP6: Objectives

Design, implementation, and testing of a collection of techniques for: . (Semi-)automatic configuration of the various levels of the query transformation system. . Automatic efficient rewriting of end-user queries into queries

• ver the data sources.

. Tuning the different components of the query transformation system in response to changes in

. the ontology and mapping layers, . the query load, and . the data source configuration.
