Abstract: While it is agreed that semantic enrichment of resources would lead to better search results, at present the low coverage of resources on the web with semantic information presents a major hurdle in realizing the vision of search on the Semantic Web. To address this problem we investigate how to improve retrieval performance in a setting where resources are sparsely annotated with semantic information. We suggest employing techniques from associative information retrieval to find relevant material, which was not originally annotated with the concepts used in a query. We present an associative retrieval system for the Semantic Desktop and show how the use of associative retrieval increased retrieval performance. Key Words: semantic desktop, associative information retrieval Category: H.3.3, I.2.4, I.2.6, I.2.11

While it is agreed that semantic enrichment of resources would lead to better search results, at present the low coverage of resources on the web with semantic information presents a major hurdle in realizing the vision of search on the Semantic Web. To address this problem, we investigate how to improve retrieval performance in settings where resources are sparsely annotated with semantic information. Techniques from soft computing are employed to find relevant material which was not originally annotated with the concepts used in a query. We present an associative retrieval model for the Semantic Web and evaluate if and to which extent the use of associative retrieval techniques increases retrieval performance. The evaluation of new retrieval paradigms- such as retrieval based on technology for the Semantic Web- presents an additional challenge since no off-the-shelf test corpora exist. Hence we give a detailed description of the approach taken to evaluate the information retrieval service we have built.

This paper is a critical analysis of the concept of ontology thus as it is used in computing science. It identifies three main problems with such a concept, two of which are intrinsic to it and one of which is extrinsic, so to speak, being related to the use of ontology in applications. The first problem with ontology is that the only accepted definition of its main artifact is teleological rather than structural as it would be proper in computing science. The second problem is that claiming that ontology is in any way a semantic discipline requires such a limited and outdated notion of semantic to be to all practical purposes useless. The third and final problem is that the limitations and misconceptions of ontology might make it a limiting factor, rather than a help, for many of the applications for which it is sought. The article concludes that a profound reconsideration of the relation between computers and semantics might be overdue. 1

tributions. A continuity of goals between Gofai and the SW hasn’t meant continuity of research traditions; this is both a gain and a loss. We’ve gained simpler representation schemes that are probably computable. The loss is due to the lack of sophistication in current schemes of the DAML+OIL (www. w3.org/TR/daml+oil-reference) family and whether they now have the representational power to handle the complexity of the commonsense or scientific world, a point I return to later. There have been at least two other traditions of input to what we now call the SW, and I’ll discuss one in some detail: the way

What will it be like to admit Artificial Companions into our society? How will they change our relations with each other? How important will they be in the emotional and practical lives of their owners---since we know that people became emotionally dependent even on simple devices like the Tamagotchi? How much social life might they have in contacting each other? The contributors to this book assume that some form of long-term computer Companions are now a certainty in the coming years, and that it is a good moment to consider from a set of wide interdisciplinary perspectives, both how we shall construct them technically as well as their personal and social consequences. By Companions we mean conversationalists or confidants----not robots--- but rather computer software agents whose function will be to get to know their owners, who may well be elderly or lonely, and focusing not only on assistance via the internet (contacts, travel, doctors etc.) that many still find hard to use, but also on providing company and Companionship, by offering aspects of personalization. The human-Companion relationship could also be used to build a life narrative of the owner, eliciting over a long period a structure of the owner's life, perhaps in a level of detail that even their relatives might not recognize, or know about. You could call that autobiography

The Semantic Web is a vision of a web of linked data, allowing querying, integration and sharing of data from distributed sources in heterogeneous formats, using ontologies to provide an associated and explicit semantic interpretation. The article describes the series of layered formalisms and standards that underlie this vision, and chronicles their historical and ongoing development. A number of applications, scientific and otherwise, academic and commercial, are reviewed. The Semantic Web has often been a controversial enterprise, and some of the controversies are reviewed, and misconceptions defused.

Abstract. This paper looks at the issue of privacy and anonymity through the prism of Scott’s concept of legibility i.e. the desire of the state to obtain an ever more accurate mapping of its domain and the actors in its domain. We argue that privacy was absent in village life in the past, and it has arisen as a temporary phenomenon arising from the lack of appropriate technology to make all life in the city legible. Cities have been the loci of creativity for the major part of human civilisation. There is something specific about the illegibility of cities which facilitates creativity and innovation. By providing the technology to catalogue and classify all objects and ideas around us, this leads to a consideration of semantic web technologies, Linked Data and the Internet of Things as unwittingly furthering this ever greater legibility. There is a danger that the over description of a domain will lead to a loss in creativity and innovation. We conclude by arguing that our prime concern must be to preserve illegibility because the survival of some form, any form, of civilisation depends upon it.
