This volume constitutes the thoroughly refereed proceedings of 11 international workshops held as part of the 8th Extended Semantic Web Conference, ESWC 2011, in Heraklion, Crete, Greece, in May 2010. The 22 revised full papers presented were carefully reviewed and selected from a total of 75 submissions to the workshops during two rounds of reviewing and improvement. The papers are organized in topical sections on the following workshops: 1st International Workshop on eLearning Approaches for the Linked Data Age, 1st Workshop on High-Performance Computing for the Semantic Web, 3rd International Workshop on Inductive Reasoning and Machine Learning for the Semantic Web, 1st Workshop on Making Sense of Microposts, 1st Workshop on Ontology and Semantic Web for Manufacturing, 1st Workshop on Question Answering over Linked Data, 4th International Workshop on REsource Discovery, 6th International Workshop on Semantic Business Process Management, 1st Workshop on Semantic Publication, 1st Workshop on Semantics in Governance and Policy Modelling, and 1st International Workshop on User Profile Data on the Social Semantic Web.

These proceedings contain the papers accepted for presentation at the Second International Semantic Web Conference (ISWC 2003) held on Sanibel Island, Florida, U. S. A. , October 20-23, 2003. Following the success of ISWC 2002 that washeldinSardiniainJune2002,ISWC2003enjoyedagreatlyincreasedinterest in the conference themes. The number of submitted papers more than doubled compared with ISWC 2002 to 283. Of those, 262 were submitted to the research track and 21 to the industrial track. With rare exceptions, each submission was evaluated by three program committee members whose reviews were coordinated by members of the senior program committee. This year 49 papers in the research track and 9 papers in the industrial track were accepted. The high quality of ISWC 2003 was the result of the joint e?ort of many people. First of all we would like to thank the authors for their high-quality submissions and the members of the program committee for their reviewing and review coordination e?orts. We would like to extend special thanks to Christoph Bussler for chairing the industrial track, to Mike Dean for his help with the conference management software, the web site, and conference publicity, and to Massimo Paolucci for helping with the organization of the proceedings and arranging sponsorships.

Researchers in Artificial Intelligence have traditionally been classified into two categories: the "neaties" and the "scruffies". According to the scruffies, the neaties concentrate on building elegant formal frameworks, whose properties are beautifully expressed by means of definitions, lemmas, and theorems, but which are of little or no use when tackling real-world problems. The scruffies are described (by the neaties) as those researchers who build superficially impressive systems that may perform extremely well on one particular case study, but whose properties and underlying theories are hidden in their implementation, if they exist at all. As a life-long, non-card-carrying scruffy, I was naturally a bit suspicious when I first started collaborating with Dieter Fensel, whose work bears all the formal hallmarks of a true neaty. Even more alarming, his primary research goal was to provide sound, formal foundations to the area of knowledge-based systems, a traditional stronghold of the scruffies - one of whom had famously declared it "an art", thus attempting to place it outside the range of the neaties (and to a large extent succeeding in doing so).

This thorough book on semantically enabled Web service technology includes an overview of significant technological achievements, accompanied by examples from real-world settings, definitions, techniques and potential directions of research and development.

This book lays the foundations for understanding the requirements that shape the description of the various aspects related to Semantic Web services. The authors introduce the Web Service Modeling Language (WSML) in the form of ontologies.

Intelligent Information Integration in B2B Electronic Commerce discusses the main problems of information integration in this area and sketches several technological solution paths.

This book offers a practical introduction to Web Service Modeling Ontology (WSMO), from the fundamentals to applications in e-commerce, e-government and e-banking, also describing its relation to related technology like OWL-S and WSDL-S. Also offers pointers to future research.

This second edition systematically introduces the notion of ontologies to the non-expert reader and demonstrates in detail how to apply this conceptual framework for improved intranet retrieval of corporate information and knowledge and for enhanced Internet-based electronic commerce.
