Knowledge engineering: principles and methods

Rudi Studer; V. Richard Benjamins; Dieter Fensel

This paper gives an overview of the development of the field of Knowledge Engineering over the last 15 years. We discuss the paradigm shift from a transfer view to a modeling view and describe two approaches which considerably shaped research in Knowledge Engineering: Role-limiting Methods and Generic Tasks. To illustrate various concepts and methods which evolved in recent years we describe three modeling frameworks: CommonKADS, MIKE and PROTEGE-II. This description is supplemented by discussing some important methodological developments in more detail: specification languages for knowledge-based systems, problem-solving methods and ontologies. We conclude by outlining the relationship of Knowledge Engineering to Software Engineering, Information Integration and Knowledge Management.

Ontologies are becoming increasingly more important in many different areas, including the knowledge management area. In knowledge management, ontologies can be used as an instrument to make knowledge assets intelligently accessible to people in organizations through an Intranet or the Internet. Most enterprises agree that knowledge is an essential asset for success and survival on an increasingly competitive and global market. In this paper, we present an ontology-based approach through a large-scale initiative involving knowledge management for the knowledge-acquisition research community.

Device understanding and modeling for diagnosis

Ameen Abu-Hanna; V. Richard Benjamins; Wouter N. H. Jansweijer

It is argued that a device model must reflect understanding of how the device functions in the real world. The nature of models, the ontology of abstract models, and the role this ontology plays in diagnosis are examined. Organizational principles for (device) diagnosis models are identified. The efficient integration of functional-design models with other diagnosis models is discussed. The implementation of the concepts in the Faulty-II system is briefly described.<<ETX>>

Applications of Ontologies and Problem- Solving Methods

Asunción Gómez-Pérez; V. Richard Benjamins

The Workshop on Applications of Ontologies and Problem-Solving Methods (PSMs), held in conjunction with the Thirteenth Biennial European Conference on Artificial Intelligence (ECAI-98), was held on 24 to 25 August 1998. Twenty-six people participated, and 16 papers were presented. Participants included scientists and practitioners from both the ontology and PSM communities. The first day was devoted to paper presentations and discussions. The second (half) day, a joint session was held with two other workshops: (1) Building, Maintaining, and Using Organizational Memories and (2) Intelligent Information Integration. The reason for the joint session was that in all three workshops, ontologies play a prominent role, and the goal was to bring together researchers working on related issues in different communities. The workshop ended with a discussion about the added value of a combined ontologies-PSM workshop compared to separate workshops.

Supporting newly‐appointed judges: a legal knowledge management case study

Pompeu Casanovas; Marta Poblet; Núria Casellas; Jesús Contreras; V. Richard Benjamins; Mercedes Blázquez

Purpose – In this paper we describe the process of developing and implementing a knowledge management system for the Spanish judicial domain. Spanish judges, especially newly‐recruited ones, hold a solid background of theoretical legal knowledge, but are much less familiar with the judicial knowledge of the more senior judges acquired from everyday practice and case resolution. The aim of this development is to capture and model these two aspects of judicial knowledge – theoretical and practical – for knowledge browsing and retrieving.Design/methodology/approach – Semantic web technologies are applied to feed a question‐answering system based on ontologies of professional legal knowledge (OPLK).Findings – There is a kind of specific legal knowledge, which belongs properly to the expert domain, not being captured by current legal core ontologies, i.e. Judges require clues, hints or well‐grounded practical guidelines that refer to the problem they have before them when they put a question or start the query...

Neptuno: Semantic Web Technologies for a Digital Newspaper Archive

Pablo Castells; Ferran Perdrix; Estrella Pulido; Mariano Rico; V. Richard Benjamins; Jesús Contreras; Jesús Lorés

Newspaper archives are a fundamental working tool for editorial teams. Their exploitation in digital format through the web, and the provision of technology to make this possible, are also important businesses today. The volume of archive contents, and the complexity of human teams that create and maintain them, give rise to diverse management difficulties. We propose the introduction of the emergent semantic-based technologies to improve the processes of creation, maintenance, and exploitation of the digital archive of a newspaper. We describe a platform based on these technologies, that consists of a) a knowledge base associated to the newspaper archive, based on an ontology for the description of journalistic information, b) a semantic search module, and c) a module for content browsing and visualisation based on ontologies.

Next generation knowledge access

John Davies; Alistair Duke; Nick Kings; Dunja Mladenic; Kalina Bontcheva; Miha Grcar; V. Richard Benjamins; Jesús Contreras; Mercedes Blázquez Civico; Tim Glover

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 withi...

Knowledge Engineering: Survey and Future Directions

Rudi Studer; Dieter Fensel; Stefan Decker; V. Richard Benjamins

This paper provides an overview of important developments in the field of Knowledge Engineering. We discuss the paradigm shift from a transfer to a modeling approach and discuss two prominent methodological achievements: problem-solving methods and ontologies. To illustrate these and additional concepts we outline several modeling frameworks: CommonKADS, MIKE, PROTEGE-II, and D3. We also discuss two fields which have emerged in the last few years and are promising areas for applying and further developing concepts and methods from Knowledge Engineering: Intelligent Information Integration and Knowledge Management.

OPJK and DILIGENT: ontology modeling in a distributed environment

Pompeu Casanovas; Núria Casellas; Christoph Tempich; Denny Vrandecic; V. Richard Benjamins

In the legal domain, ontologies enjoy quite some reputation as a way to model normative knowledge about laws and jurisprudence. This paper describes the methodology followed when developing the ontology used by the second version of the prototype Iuriservice, a web-based intelligent FAQ for judicial use. This modeling methodology has had two important requirements: on the one hand, the ontology needed to be extracted from a repository of professional judicial knowledge (containing nearly 800 questions regarding daily practice). Thus, the construction of ontologies of professional judicial knowledge demanded the description of this knowledge as it is perceived by the judge. On the other hand, due to the distributiveness of the environment, there was a need for controlled discussion and traceability of the arguments used in favor or against the introduction of a concept X as part of the domain ontology. This paper presents the Ontology of Professional Judicial Knowledge (OPJK), extracted manually from the selection of relevant terms from judicial practice questions and modeled according to the DILIGENT methodology. We will show that DILIGENT has proved to be a methodology that facilitates the ontology engineering in a distributed environment, although appropriate tool support needs to be developed.
