He co-chaired the SWS Challenge initiative for several years, served in the steering committee and as a track chair for the S3 Contest initiative and has held tutorials about the evaluation of semantic technologies.</p><p>David Martin is a Software Engineering Manager in the Siri team at Apple (Cupertino, California, USA), and previously was a Senior Computer Scientist in the Artificial Intelligence Center of SRI International. His research areas include agent-based systems, Semantic Web and Semantic Web Services, intelligent assistance, and knowledge-based systems engineering. David was a Principal Investigator for DARPA's DAML program that created the Semantic Web initiative, and had a leading role in the development of OWL for Services (OWL-S) and the Semantic Web Services Language (SWSL). He has served as an organizer of many workshops related to Web Services, including the combined Service Matching and Resource Retrieval and Semantic Service Selection (SMR2 / S3) series of workshops and the first SWS Challenge workshop.</p>

<p>Over the last decade, a great amount of effort and resources have been invested in the development of Semantic Web Service (SWS) frameworks. Numerous description languages, frameworks, tools, and matchmaking and composition algorithms have been proposed. Nevertheless, when faced with a real-world problem, it is still very hard to decide which of these different approaches to use.</p><p>In this book, the editors present an overall overview and comparison of the main current evaluation initiatives for SWS. The presentation is divided into four parts, each referring to one of the evaluation initiatives. Part I covers the long-established first two tracks of the Semantic Service Selection (S3) Contest – the OWL-S matchmaker evaluation and the SAWSDL matchmaker evaluation. Part II introduces the new S3 Jena Geography Dataset (JGD) cross evaluation contest. Part III presents the Semantic Web Service Challenge. Lastly, Part IV reports on the semantic aspects of the Web Service Challenge. The introduction to each part provides an overview of the evaluation initiative and overall results for its latest evaluation workshops. The following chapters in each part, written by the participants, detail their approaches, solutions and lessons learned.</p>This book is aimed at two different types of readers. Researchers on SWS technology receive an overview of existing approaches in SWS with a particular focus on evaluation approaches; potential users of SWS technologies receive a comprehensive summary of the respective strengths and weaknesses of current systems and thus guidance on factors that play a role in evaluation.

<p>Reports on the results, experiences and lessons learned from various evaluation initiatives for Semantic Web Services (SWS)</p><p>Provides an overview of the state of the art with respect to implemented SWS technologies</p><p>Details the variety of current Semantic service approaches for users and tool providers</p><p>Provides valuable information to enhance future evaluation methodologies and techniques for SWS</p><p>Includes supplementary material: sn.pub/extras</p>
