To describe how semantic knowledge technology can be used to enhance a digital library.

The paper examines the main research challenges in the field of digital libraries and identifies the extent to which semantic knowledge technology can be used to respond to these challenges. Functionality developed within the SEKT project (http://sekt.semanticweb.org) is used to enhance an existing digital library. The development of a good ontology is central to such an application, and the paper describes the particular ontology engineering approach adopted.

Four broad challenges were identified: achieving interoperability; describing objects and repositories; managing multimedia collections; and improving user interfaces and human‐computer interaction. The SEKT digital library case study is using semantic knowledge technology to respond to the first two and the last of these. The paper describes how this is being done and the kind of enhanced functionality being developed.

The paper is of value in understanding how semantic knowledge technology can enhance information management in general and a digital library in particular.

This paper describes the application of semantic knowledge technology to a case study in intelligent content management, specifically the BT digital library. The intention is to test the technology being developed within semantically‐enabled knowledge technology (SEKT) and provide feedback to the development process. This will verify the viability of our technology and verify that we are using semantic knowledge technology to satisfy the real requirements of users. The case study will also serve as a shop window for the technology.

During the initial stage of the project, user requirements were collected by means of a questionnaire and also an in‐depth focus group. Combined with a study of the existing literature on digital libraries, this enabled an enhanced digital library system to be designed using SEKT technologies.

Work so far has verified that semantic knowledge technologies can be used to enhance the value of digital libraries. During the later stages of the SEKT project detailed trials will enable the SEKT functionality to be fine‐tuned for the precise needs of users.

To be of value, semantic knowledge technologies must take into account the needs and behaviour of users. For example, a strong lesson from our focus group was that users wish to feel in control of the technology.

The paper illustrates how semantic knowledge technology can be used in a specific application. This application is valuable in itself, and will provide feedback to help understand how semantic knowledge technology can be used to provide user benefit in general.

The archives of François Perroux deposited at IMEC bear witness to the fact that he has devoted, beyond his scientific production, great energy to the most material aspects of research: setting up and maintaining networks to publicize his work and that of other economists, either directly or through the institutes and the journals he headed; organize seminars and symposiums; take care of relations with colleagues and the press; create collections and journals; and so on.

In this chapter, we concentrate our attention on the archives relating to the management of the institutes, those attesting to the lines and themes of the producer’s research, and those concerning his important correspondence.

Thanks to the archives deposited at IMEC, it is possible to follow the development of the theoretical work of François Perroux by contextualizing it. They also show the itinerary of a Christian intellectual, whose attachment to social Catholicism constitutes a guiding thread and is reflected in all his activities. Finally, the archives illuminate his substantial role in the institutionalization of research in economics in the France of the twentieth century.

The aim of this paper is to introduce the special issue on the Semantic Web. Intensive research has been undertaken worldwide in research centres and several achievements have been accomplished towards the ultimate objective: the expression and the exploitation of humanity's collective knowledge.

A multi‐fold strategy for the preparation of this special issue was deployed. Given the special characteristics, a balanced mix of introductory papers to the topic, and also advanced research papers at the leading edge of Semantic Web evolution, were selected.

The paper summarizes the articles of the issue and also provides help in understanding the Semantic Web Roadmap of Digital Libraries.

Introduces the papers in the special issue.

Since the 1950s four distinct inductive research traditions developed in California, following the migrations of Herbert Blumer, Erving Goffman, Anselm Strauss, Harold Garfinkel, Jack Douglas, and others. Each of these traditions has made intellectual, organizational, service, pedagogical, financial, and personal contributions to the growth and development of symbolic interaction.

To investigate the nature of investment expertise and factors affecting the information processing and performance of investment experts, this paper hypothesizes normative characteristics of investment expertise and compares such characteristics with actual characteristics documented in prior literature on the investment expert. Based on collective evidence from these sources, a model of investment expertise is proposed.

Results support the existence of investment expertise in (1) the nature of knowledge, (2) problem solving and information search, and (3) performance. A variety of factors that could influence the information processing and performance of the investment expert, including personal, cognitive, and contextual elements, are also discussed in the paper and included in the proposed model of investment expertise.
