Semantic web-based document: editing and browsing in AktiveDoc

This paper presents a tool for supporting sharing and reuse of knowledge in document creation (writing) and use (reading). Semantic Web technologies are used to support the production of ontology based annotations while the document is written. Free text annotations (comments) can be added to integrate the knowledge in the document. In addition the tool uses external services (e.g. a Semantic Web harvester) to propose relevant content to writing user, enabling easy knowledge reuse. Similar facilities are provided for readers when their task does not coincide with the author’s one. The tool is specifically designed for Knowledge Management in organisations. In this paper we present and discuss how Semantic Web technologies are designed and integrated in the system

Collaborative semantic web browsing with Magpie

Web browsing is often a collaborative activity. Users involved in a joint information gathering exercise will wish to share knowledge about the web pages visited and the contents found. Magpie is a suite of tools supporting the interpretation of web pages and semantically enriched web browsing. By automatically associating an ontology-based semantic layer to web resources, Magpie allows relevant services to be invoked as well as remotely triggered within a standard web browser. In this paper we describe how Magpie trigger services can provide semantic support to collaborative browsing activities

Designing a Personalized Semantic Web Browser

Web browsing is a complex activity and in general, users are not guided during browsing. Our hypothesis is that by using Semantic Web technologies and personalization methods, browsing can be supported better. However, existing personalization mechanisms on the Web are obstructive; users need to log in to multiple websites and enter their personal information and preferences, and the profiles are different for each site. There is a need for generic user profiles, which can also support the user’s browsing. In this paper, we propose a novel Semantic Web browser using an ontology-driven user modeling architecture to enable semantic and adaptive links. We also introduce a new behavior-based user model. With our approach, users need to log in to their Web browser only and personalization is achieved on different websites

Study on integrating semantic applications with Magpie

This paper describes two approaches to integrating standalone information processing techniques into a semantic application capable of acquiring and maintaining knowledge, which we conducted using our open Semantic Web framework of Magpie. We distinguish between integration through aggregation and through choreographing, and argue that the latter is not only simpler to realize but also provides greater benefits. The benefits were, in our experiment, related to developing a capability of maintaining and validating knowledge through an integration of down- and upstream knowledge processing tools. We describe the principles of integration and relate them to pragmatic challenges for the semantic web and to strategic directions of its evolution

Knowledge Management In A Distributed Organisation

this paper we introduce the research in scope of KnowWeb (EC funded project). We focus our attention on two important issues -- (i) how to capture tacit, contextual knowledge that is connected to the documents and (ii) how to support knowledge management in geographically distributed organisations through up-to-date communication and AI technologie

Integrating External Sources in a Corporate Semantic Web Managed by a Multi-agent System

We first describe a multi-agent system managing a corporate memory in the form of a corporate semantic web. We then focus on a newly introduced society of agents in charge of wrapping external HTML documents that are relevant to the activities of the organization, by extracting semantic Web annotations using tailored XSLT templates. Agents and corporate semantic webs Organizations are entities living in a world with a past, a culture and inhabited by other actors; the pool of knowledge they mobilize for their activities is not bounded neither by their walls nor by their organizational structures: organizational memories may include or refer to resources external to the company (catalogs of norms, stock-markets quotations, digital libraries, etc.). Our research team currently studies the materialization of a corporate memory as a corporate semantic web; this follows the general trend to deploy organizational information systems using internet and web technologies to build intranets and intrawebs (internal webs, corporate webs). The semantic intraweb that we shall consider here, comprises an ontology (O'CoMMA [Gandon, 2001]) encoded in RDFS, descriptions of the organizational reality encoded as RDF annotations about the groups (corporate model) and the persons (user profiles), and RDF annotations about the documentary resources. The result of this approach is a heterogeneous and distributed information landscape, semantically annotated using the conceptual primitives provided by the ontology. To manage this corporate knowledge, it is interesting to rely on a software architecture that is itself heterogeneous and distributed, and the adequacy of multi-agent systems have been acknowledged in a range of projects proposing multi-agent systems addressing different aspects of knowledge management inside organizations. CASMIR [Berney and Ferneley, 1999] and Ricochet [Bothorel and Thomas, 1999] focus on the gathering of information an
