Abstract

The main research focus toward the Semantic Web vision has been so far on conceptualization, while little concern was spent on the efficiency aspect. In this paper we present practical experiences gained with the implementation of a use case from the geospatial domain, in particular a semi-automatic semantic composition of the functionality provided by 7 geospatial web services. Although we obtained the desired results with our initial approach, the performance aspect was unsatisfactory. For this reason we started the investigation into how significant performance improvements could be obtained. We identified rule engines as a solution that would easily fit into our framework and also were mature enough in terms of complexity and execution speed. We provide a new execution solution based on JBoss Rules and compare it with previous implementations.
