A Knowledge-Based News Server Supporting Ontology-Driven Story Enrichment and Knowledge Retrieval

Abstract

Abstract. We consider a knowledge management scenario in which members of an academic community collaboratively construct and share a common archive of news items. Given this scenario, a number of knowledge management challenges arise: how to organize a speedy, low overhead publication process which can nevertheless yield high quality results; how to provide semantic search and knowledge retrieval facilities in an effective and sustainable way; how best to provide individualized presentations and news alerts. To address these questions we have drawn on a number of technologies, including knowledge modelling, autonomous agents, software visualization, knowledge acquisition and distributed computing. In the paper we describe the resulting Planet-Onto architecture, which provides an integrated set of tools to support news publishing, ontology-driven document formalization, story identification and personalized news feeds and alerts.

An Architecture for Semantic Navigation and Reasoning with Patient Data - Experiences of the Health-e-Child Project

“…temporally); to display a data schema or to inform navigation through the data [22]. In particular cases, ontology-based visualization has been used to support queries based on temporal abstractions [23]; to enrich maps with additional geographic information [24]; to reveal multiple levels of abstraction in decision-tree generation [25] and to assist in information mining [26]; very popularly, to map social networks and communities of common interest [27], [28], [29]. Ontologies have also been used for knowledge discovery without visualization, especially in the integration of heterogeneous scientific repositories ( [30]).…”

An agent-mediated approach to the support of knowledge sharing in organizations

“…The first steps towards the realization of these objectives concerned the development of a Community of Practice, the KennisNet, incorporating the facilitation of direct contacts between members and an intranet-based knowledge-sharing server using existing technical infrastructure, a Lotus Notes network, are depicted in Figure 2. The development of the knowledge repository was inspired on work by [16], [25] and [20]. Its functionality enables direct access to contents, publishing and browsing of knowledge items, and allows the implementation of facilities for discussion and broadcast of questions and requests.…”

Uma visão geral sobre ontologias: pesquisa sobre definições, tipos, aplicações, métodos de avaliação e de construção

“…Ontologias são utilizadas hoje em diversas áreas para organizar a informação (Bateman, 1996;Borgo et alii, 1997;Aguado et alii,, 1998;Domingue, 1998;Hasman et alii, 1999;Shum;Motta & Domingue, 2000;Leger et alii, 2000;Kalfoglou, 2001;Vázquez, Valera & Bellido, 2001;Gandon, 2001;Martin & Eklund, 2001;Alexaki et alii, 2002). São encontradas na literatura diversas definições para as ontologias, diversos tipos, propostas para aplicação em diferentes áreas de conhecimento e propostas para a construção de ontologias (metodologias, ferramentas e linguagens).…”
