This book contains a collection of thoroughly revised tutorial papers based on lectures given by leading researchers at the 5th International Summer School on the Reasoning Web, held in Brixen - Bressanone, Italy, in August 30 - September 4, 2009. The objective of the book is to provide a coherent introduction to semantic web methods and research issues with a particular focus on reasoning.The seven tutorial papers presented provide competent coverage of methods and major application areas such as social networks, semantic multimedia indexing and retrieval, bioinformatics, and semantic web services. This year edition focused on the use of semantic technologies to enhance data access on the web. Topics of the lectures where design and analysis of reasoning procedures for Description Logics, Answer Set Programming basics, its modeling methodology and its principal extensions tailored for Semantic Web applications, languages for constraining and querying XML data, RDF databases theory and efficient and scalable support for RDF/OWL data storage, loading, inferencing and querying, tractable Description Logics and their use for Ontology-Based Data Access, the Social Semantic Desktop, which defines a user's personal information environment as a source and end-point of the Semantic Web.

Description Logics.- Answer Set Programming: A Primer.- Logical Foundations of XML and XQuery.- Foundations of RDF Databases.- Database Technologies for RDF.- Technologies for the Social Semantic Desktop.- Ontologies and Databases: The DL-Lite Approach.
