From the reviews: "Ouzzani and Bouguettaya present an efficient and novel query structure based on the concept of quality of Web service (QoWS). They describe this as a contribution to the semantic Web, where software agents formulate queries on behalf of humans. ... For those who work with Web databases, optimization, and Web services, this book provides good background in ontology, the semantic Web, and Web databases. ... The book delivers a very good overview of the process of developing strategies for working with ontologies, queries, and optimization." (Alyx Macfadyen, ACM Computing Reviews, June, 2012)
