This document evaluates the effectiveness of CKR queries through a benchmark of 32 queries on a FIFA World Cup knowledge base. A first set of queries has been chosen by the authors, with the goal of stressing the contexts structure and the context dependent knowledge, while the remaining queries have been taken from a generic website of quizzes about the FIFA World Cup. Queries are formulated against both the CKR and the ‘flat’ OWL versions of the knowledge base. The document compares the different formulations and reports their corresponding query evaluation times.

Abstract
This document evaluates the effectiveness of CKR queries through a benchmark of 32 queries on a FIFA World Cup knowledge base. A first set of queries has been chosen by the authors, with the goal of stressing the contexts structure and the context dependent knowledge, while the remaining queries have been taken from a generic website of quizzes about the FIFA World Cup. Queries are formulated against both the CKR and the ‘flat’ OWL versions of the knowledge base. The document compares the different formulations and reports their corresponding query evaluation times.
