Next generation knowledge access

Abstract

Purpose-The paper shows how access to knowledge can be enhanced by using a set of innovative approaches and technologies based on the semantic web. Design/methodology/approach-Emerging trends in knowledge access are considered followed by a description of how ontologies and semantics can contribute. A set of tools is then presented which is based on semantic web technology. For each of these tools a detailed description of the approach is given together with an analysis of related and future work as appropriate. Findings-The tools presented are at the prototype stage but can already show how knowledge access can be improved by allowing users to more precisely express what they are looking for and by presenting to them in a form that is appropriate to their current context. Research limitations/implications-The tools show promising results in improving access to knowledge which will be further evaluated within a practical setting. The tools will be integrated and trialled as part of case studies within the SEKT project. This will allow their usability and practical applicability to be measured. Practical implications-Ontologies as a form of knowledge representation are increasing in importance. Knowledge management, and in particular knowledge access, will benefit from their widespread acceptance. The use of open standards and compatible tools in this area will be important to support interoperability and widespread access to disparate knowledge repositories. Originality/value-The paper presents research in an emerging but increasingly important field, i.e. semantic web-based knowledge technology. It describes how this technology can satisfy the demand for improved knowledge access, including providing knowledge delivery to users at the right time and in the correct form.

Adaptive hypermedia for the semantic web

“…Alternative is, like with domain ontologies, to apply ontology mapping techniques in order to map between two different user model ontologies [35]. Furthermore, it is also possible to learn user profiles and automatically construct user model ontologies for a specific system or a class of systems [12].…”

An analysis of knowledge management mechanisms in healthcare portals

“…Specifically, users can access knowledge through searching, browsing, personalization, accessibility options, multimedia and multilingual support. The mechanism highlights the importance of tools that are able to integrate capabilities for searching information with greater precision and tools that are able to personalize the content and presentation of the interface (Davies et al, 2005).…”

Ontology-based Collaborative Inter-organizational Knowledge Management Network

“…In this approach, explicit knowledge of the KMS is annotated in a form that is machineprocessable metadata based on the domain or topic-specific ontology (Davies et al, 2005;Mentzas et al, 2001). Using the ontology, one KMS can communicate with others in spite of the underlying system, syntax, and structure heterogeneities, thus allowing the involved systems to understand incoming requests and return the required knowledge as they are using the same set of vocabularies.…”
