Requirements, Design and Applications to Semantic Integration and Knowledge Discovery
Practical Ontologies: Requirements, Design and Applications to Semantic Integration and Knowledge Discovery by Daniela Rosu A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Computer Science University of Toronto © Copyright by Daniela Rosu 2013 Practical Ontologies: Requirements, Design and Applications to Semantic Integration and Knowledge Discovery Daniela Rosu Doctor of Philosophy Graduate Department of Computer Science University of Toronto 2013 Abstract Due to their role in describing the semantics of information, knowledge representations, from formal ontologies to informal representations such as folksonomies, are becoming increasingly important in facilitating the exchange of information, as well as the semantic integration of information systems and knowledge discovery in a large number of areas, from e-commerce to bioinformatics. In this thesis we present several studies related to the development and application of knowledge representations, in the form of practical ontologies. In Chapter 2, we examine representational challenges and requirements for describing practical domain knowledge. We present representational requirements we collected by surveying current and potential ontology users, discuss current approaches to codifying knowledge and give formal representation solutions to some of the issues we identified. In Chapter 3 we introduce a practical ontology for representing data exchanges, discuss its relationship with existing standards and its role in facilitating the interoperability between information producing and consuming services. ii We also consider the problem of assessing similarity between ontological concepts and propose three novel measures of similarity, detailed in Chapter 4. Two of our proposals estimate semantic similarity between concepts in the same ontology, while the third measures similarity between concepts belonging to different ontologies. -

List of Different Digital Practices 3
Categories of Digital Poetics Practices (from the Electronic Literature Collection) http://collection.eliterature.org/1/ (Electronic Literature Collection, Vol 1) http://collection.eliterature.org/2/ (Electronic Literature Collection, Vol 2) Ambient: Work that plays by itself, meant to evoke or engage intermittent attention, as a painting or scrolling feed would; in John Cayley’s words, “a dynamic linguistic wall- hanging.” Such work does not require or particularly invite a focused reading session. Kinetic (Animated): Kinetic work is composed with moving images and/or text but is rarely an actual animated cartoon. Transclusion, Mash-Up, or Appropriation: When the supply text for a piece is not composed by the authors, but rather collected or mined from online or print sources, it is appropriated. The result of appropriation may be a “mashup,” a website or other piece of digital media that uses content from more than one source in a new configuration. Audio: Any work with an audio component, including speech, music, or sound effects. CAVE: An immersive, shared virtual reality environment created using goggles and several pairs of projectors, each pair pointing to the wall of a small room. Chatterbot/Conversational Character: A chatterbot is a computer program designed to simulate a conversation with one or more human users, usually in text. Chatterbots sometimes seem to offer intelligent responses by matching keywords in input, using statistical methods, or building models of conversation topic and emotional state. Early systems such as Eliza and Parry demonstrated that simple programs could be effective in many ways. Chatterbots may also be referred to as talk bots, chat bots, simply “bots,” or chatterboxes. -

A Method to Analyze Multiple Social Identities in Twitter Bios
A Method to Analyze Multiple Social Identities in Twitter Bios ARJUNIL PATHAK, University at Buffalo, USA NAVID MADANI, University at Buffalo, USA KENNETH JOSEPH, University at Buffalo, USA Twitter users signal social identity in their profile descriptions, or bios, in a number of important but complex ways that are not well-captured by existing characterizations of how identity is expressed in language. Better ways of defining and measuring these expressions may therefore be useful both in understanding howsocial identity is expressed in text, and how the self is presented on Twitter. To this end, the present work makes three contributions. First, using qualitative methods, we identify and define the concept of a personal identifier, which is more representative of the ways in which identity is signaled in Twitter bios. Second, we propose a method to extract all personal identifiers expressed in a given bio. Finally, we present a series of validation analyses that explore the strengths and limitations of our proposed method. Our work opens up exciting new opportunities at the intersection between the social psychological study of social identity and the study of how we compose the self through markers of identity on Twitter and in social media more generally.

Where Is the Semantic Web? – an Overview of the Use of Embeddable Semantics in Austria
Where Is The Semantic Web? – An Overview of the Use of Embeddable Semantics in Austria Wilhelm Loibl Institute for Service Marketing and Tourism Vienna University of Economics and Business, Austria [email protected] Abstract Improving the results of search engines and enabling new online applications are two of the main aims of the Semantic Web. For a machine to be able to read and interpret semantic information, this content has to be offered online first. With several technologies available the question arises which one to use. Those who want to build the software necessary to interpret the offered data have to know what information is available and in which format. In order to answer these questions, the author analysed the business websites of different Austrian industry sectors as to what semantic information is embedded. Preliminary results show that, although overall usage numbers are still small, certain differences between individual sectors exist. Keywords: semantic web, RDFa, microformats, Austria, industry sectors 1 Introduction As tourism is a very information-intense industry (Werthner & Klein, 1999), especially novel users resort to well-known generic search engines like Google to find travel related information (Mitsche, 2005). Often, these machines do not provide satisfactory search results as their algorithms match a user’s query against the (weighted) terms found in online documents (Berry and Browne, 1999). One solution to this problem lies in “Semantic Searches” (Maedche & Staab, 2002). In order for them to work, web resources must first be annotated with additional metadata describing the content (Davies, Studer & Warren., 2006). Therefore, anyone who wants to provide data online must decide on which technology to use. -
Autonomous Agents on the Web
Report from Dagstuhl Seminar 21072 Autonomous Agents on the Web Edited by Olivier Boissier1, Andrei Ciortea2, Andreas Harth3, and Alessandro Ricci4 1 Ecole des Mines – St. Etienne, FR, [email protected] 2 Universität St. Gallen, CH, [email protected] 3 Fraunhofer IIS – Nürnberg, DE, [email protected] 4 Università di Bologna, IT, [email protected] Abstract The World Wide Web has emerged as the middleware of choice for most distributed systems. Recent standardization efforts for the Web of Things and Linked Data are now turning hypermedia into a homogeneous information fabric that interconnects everything – devices, information resources, abstract concepts, etc. The latest standards allow clients not only to browse and query, but also to observe and act on this hypermedia fabric. Researchers and practitioners are already looking for means to build more sophisticated clients able to meet their design objectives through flexible autonomous use of this hypermedia fabric. Such autonomous agents have been studied to large extent in research on distributed artificial intelligence and, in particular, multi-agent systems. These recent developments thus motivate the need for a broader perspective that can only be achieved through a concerted effort of the research communities on the Web Architecture and the Web of Things, Semantic Web and Linked Data, and Autonomous Agents and Multi-Agent Systems. The Dagstuhl Seminar 21072 on “Autonomous Agents on the Web” brought together leading scholars and practitioners across these research areas in order to support the transfer of knowledge and results – and to discuss new opportunities for research on Web-based autonomous systems. This report documents the seminar’s program and outcomes. -
