Web Service Quality Composition Determination Using Genetic Algorithm in Sematic Web

Ranking and optimization of web service compositions represent challenging areas of research with significant implications for the realization of the "Web of Services" vision. "Semantic web services" use formal semantic descriptions of web service functionality and interface to enable automated reasoning over web service compositions. To judge the quality of the overall composition, for example, the authors can start by calculating the semantic similarities between outputs and inputs of connected constituent services, and aggregate these values into a measure of semantic quality for the composition.
