Recent advances in Internet and Web technologies and the advent of Web 2.0 have made it possible to share information and knowledge surrounding human activities. These activities can be captured through the intensive deployment of sensors and the Web resources. Experiential Knowledge Mining provides a comprehensive overview of mining experiential knowledge bearing on human activities, with an emphasis on the use of the Web. Starting with definitions of activities and experiences, it elaborates on various views of human activities in cognitive science, including knowledge representation schemes. It then describes two activity detection techniques arising from different types of information sources: (1) sensor-driven approaches for the physical space and (2) text-driven approaches for the cyberspace. With a focus on experiential knowledge of human activities that can be discovered from unstructured text, Experiential Knowledge Mining reviews and summarizes the existing body of literature on experiential knowledge filtering, context identification for knowledge, and knowledge distillation. There is no doubt that the vast amount of information about human experience that includes activities is going to help detecting, recognizing, and understanding human activities of various sorts. This monograph illustrates the various potential applications of experiential knowledge in different domains like information retrieval, service recommendation, and semantic web. Experiential Knowledge Mining is the first to take a comprehensive look at this fascinating topic and acts as an ideal primer for anyone who wants to delve deeper into this subject.

This book deals with different theories, methods and implementations combining Web 2.0 paradigms and Semantic Web technologies in Enterprise environments. After introducing those terms, the current shortcomings of tools such as blogs and wikis are presented as well as tagging practices in an Enterprise 2.0 context. A definition of the SemSLATES methodology is given, as well as the global vision of a middleware architecture based on Semantic Web technologies and Linked Data principles (languages, models, tools and protocols) to solve these issues. Then, the various ontologies that we build to achieve this goal are detailed. On the one hand the models dedicated to socio-structural metadata, especially SIOC - Semantically-Interlinked Online Communities -, are presented and on the other hands models extending public ontologies for representing domain knowledge. Moreover, the MOAT - Meaning Of A Tag - ontology is discussed, providing a way to combine the flexibility of tagging and the power of ontology-based indexing. The book also describes several software implementations related to these models, done in the industrial context of EDF R&D, and dedicated to easily produce and use semantic annotations to enrich original tools: semantic wikis, advanced visualization interfaces (faceted browsing, semantic mash-ups, etc.) combined with a semantic search engine. Several contributions described in this publication have been published as public ontologies or open-source software, contributing more generally to this convergence between Web 2.0 and the Semantic Web, not only in enterprise but on the Web as a whole.

Provenance, i.e., the origin or source of something, is becoming an important concern, since it offers the means to verify data products, to infer their quality, and to decide whether they can be trusted. For instance, provenance enables the reproducibility of scientific results; provenance is necessary to track attribution and credit in curated databases; and, it is essential for reasoners to make trust judgements about the information they use over the Semantic Web. As the Web allows information sharing, discovery, aggregation, filtering and flow in an unprecedented manner, it also becomes difficult to identify the original source that produced information on the Web. This survey contends that provenance can and should reliably be tracked and exploited on the Web, and investigates the necessary foundations to achieve such a vision.

The Annual Asian Semantic Web Conference is one of the largest regional events in Asia with focused topics related to the Semantic Web. With the decade-round endeavor of Semantic Web believers, researchers and practitioners, the Semantic Web has made remarkable progress recently. It has raised significant attention from US and UK governments, as well as the European Commission who are willing to deploy Semantic Web technologies to enhance the transparency of eGovernment. The Linked Open Data initiative is on its way to convert the current document Web into a data Web and to further enabling various data and service mashups. The fast adoption of Semantic Web technologies in medical and life sciences has created impressive showcases to the world. All these efforts are a crucial step toward enabling the take-off and the success of the Semantic Web. The First Asian Semantic Web Conference was successfully held in China in 2006. With the following editions in Korea in 2007 and Thailand in 2008, it fostered a regional forum for connecting researchers and triggering innovations. This year, the 4th Asian Semantic Web Conference was held in Shanghai, China. We received 63 submissions from Asia, Europe, and North America, and 25 papers were accepted (the acceptance rate is around 40%). Each submission was reviewed by at least three members of the Program Committee. The Chairs moderated the discussion of conflict reviews or invited external reviewers to reach the final decisions.

While other books focus on special internet registers, like tweets or texting, no previous study describes the full range of everyday registers found on the searchable web. These are the documents that readers encounter every time they do a Google search, from registers like news reports, product reviews, travel blogs, discussion forums, FAQs, etc. Based on analysis of a large, near-random corpus of web documents, this monograph provides comprehensive situational, lexical, and grammatical descriptions of those registers. Beginning with a coding of each document in the corpus, the description identifies the registers that are especially common on the searchable web versus those that are less commonly found. Multi-dimensional analysis is used to describe the overall patterns of linguistic variation among web registers, while the second half of the book provides an in-depth description of each individual register, including analyses of situational contexts and communicative purposes, together with the typical lexical and grammatical characteristics associated with those contexts.

Modernity is a social, cultural, or historical descriptor for a certain type of society or set of social arrangements. It is a contentious and disputed term, often understood implicitly. It is a way of describing and classifying highly complex, dynamic, and emergent aggregate social phenomena, and so dramatically simplifies such contexts. However, the language of modernity remains attractive to commentators, academics, and policymakers. In this monograph, the author reviews the literature that characterises what is called digital modernity. Digital modernity narratives focus on the possibilities of the data gathered by an ambient data infrastructure, enabled by ubiquitous devices such as the smartphone, and activities such as social networking and e-commerce. It is characterised by (1) a subjunctive outlook where people's choices can be anticipated and improved upon, (2) the valorisation of disruptive innovation on demand, and (3) control provided by data analysis within a virtual realm that can be extended and applied to the physical world. The author explored the synergies and tensions between these three aspects as well as the opportunities for and dilemmas posed by misinformation. The author identifies five principles that emerge from the study of relevant texts and business models and concludes by contrasting digital modernity with other theories of the 21st century information society. Narratives of digital modernity are useful because they help explain the development of technology. It matters because many influential people accept, and often generate, the digital modernity narrative. Given digital modernity's strong association with the Web, it is a central topic for Web Science as the interdisciplinary study of the World Wide Web from the technological, social, and individual points of view.

With almost every business application process being linked with a web portal, the website has become an integral part of any organization. Satisfying the end user's needs is one of the key principles of designing an effective website. Because there are different users for any given website, there are different criteria that users want. Thus, evaluating a website is a multi-criteria decision-making problem in which the decision maker's opinion should be considered for ranking the website. Multi-Criteria Decision-Making Models for Website Evaluation is a critical scholarly resource that covers the strategies needed to evaluate the navigability and efficacy of websites as promotional platforms for their companies. Featuring a wide range of topics including linguistic modelling, e-services, and site quality, this book is ideal for managers, executives, website designers, graphic artists, specialists, consultants, educationalists, researchers, and students.

Knowledge in its pure state is tacit in natureOCoedifficult to formalize and communicateOCoebut can be converted into codified form and shared through both social interactions and the use of IT-based applications and systems.

Big Data and Knowledge Sharing in Virtual Organizations provides innovative insights into the influence of big data analytics and artificial intelligence and the tools, methods, and techniques for knowledge-sharing processes in virtual organizations. The content within this publication examines cloud computing, machine learning, and knowledge sharing. It is designed for government officials and organizations, policymakers, academicians, researchers, technology developers, and students.

This book addresses the problem of benchmarking semantic web technologies; first, from a methodological point of view, proposing a general methodology to follow in benchmarking activities over semantic web technologies and, second, from a practical point of view, presenting two international benchmarking activities that involved benchmarking the interoperability of semantic web technologies using RDF(S) as the interchange language in one activity and OWL in the other. The book presents in detail how the different resources needed for these interoperability benchmarking activities were defined: the experiments, the benchmark suites and the software that support the process. Furthermore, the book invites practitioners to reach a continuous improvement of semantic technologies by means of their continuous evaluation and presents future lines of research.

The Semantic Web has been a very important development in how knowledge is disseminated and manipulated on the Web, but it has been of particular importance to the flow of scientific knowledge, and will continue to shape how data is stored and accessed in a broad range of disciplines, including life sciences, earth science, materials science, and the social sciences. After first presenting papers on the foundations of semantic e-science, including papers on scientific knowledge acquisition, data integration, and workflow, this volume looks at the state of the art in each of the above-mentioned disciplines, presenting research on semantic web applications in the life, earth, materials, and social sciences. Drawing papers from three semantic web workshops, as well as papers from several invited contributors, this volume illustrates how far semantic web applications have come in helping to manage scientific information flow.
