This short case study will show on the basis of a simple example taken from the Food Safety area, how ontologies differ from thesauri. The example will start with showing an extract from the AGROVOC1 thesaurus and exploring the information that can be extracted from here. We will then develop...
This paper focuses on the AGRIS Application Profile (AGRIS AP), a standard created specifically to enhance description, exchange and subsequent retrieval of agricultural Document-Like Information Objects (DLIOs). The AGRIS AP provides a minimum interoperability layer through which agricultural information can be described and exchanged. The standard, developed in light of...
This paper presents an approach to automatically subject index fulltext documents with multiple labels based on binary support vector machines(SVM). The aim was to test the applicability of SVMs with a real world dataset. We have also explored the feasibility of incorporating multilingual background knowledge, as represented in thesauri or...
We present a novel approach of extracting a domain ontology from large-scale thesauri. Concepts are identified to be relevant for a domain based on their frequent occurrence in domain texts. The approach allows to bootstrap the ontology engineering process from given legacy thesauri and identifies an initial domain ontology that...
This paper proposes that for scientific and technical information resources, a well-structured and high-quality metadata record contains enough information to find that resource on the Internet, and as a consequence, no additional human labour is needed to create or maintain any links. Research was performed by creating a control group...
In order to provide thematic access to the large scale web site of the Food and Agriculture Organization (FAO), we have adapted a scheme used in bibliographical databases to allow subject browsing on FAO’s web site. This requires categorizing existing database records across the organizations web sites into the new...
This brief speech introduces the seminar Information management nel settore aerospaziale, outlining the strength and the weakness of the sector in a changing environment. New approaches of the information specialists and expected outputs of the AIM-EU Study are described.

The aim of the round table...
A team of information specialists based at Cranfield University Information and Library Service is currently undertaking a study of information management in the European aerospace sector on behalf of the British Library and the European Space Agency (ESA). This article provides a brief overview of the context of the study...
This paper outlines a project (involving FAO, SIFAR, and CNR) aiming at building a formal ontology in the fishery domain. The ontology will support semantic interoperability among existing fishery information systems and will enhance information extraction and text marking, envisaging a fishery semantic web. The ontology is being built through...
