- Abstract
- Formal Concept Analysis (FCA) is a well founded mathematical framework used for conceptual classication and knowledge management. Given a binary table describing a relation between objects and attributes, FCA consists in building a set of concepts organized by a subsumption relation within a concept lattice. Accordingly, FCA requires to transform complex data, e.g. numbers, intervals, graphs, into binary data leading to loss of information and poor interpretability of object classes. In this paper, we propose a pre-processing method producing binary data from complex data taking advantage of similarity between objects. As a result, the concept lattice is composed of classes being maximal sets of pairwise similar objects. This method is based on FCA and on a formalization of similarity as a tolerance relation (reexive and symmetric). It applies to complex object descriptions and especially here to interval data. Moreover, it can be applied to any kind of structured data for which a similarity can be dened (sequences, graphs, etc.). Finally, an application highlights that the resulting concept lattice plays an important role in information fusion problem, as illustrated with a real-world example in agronomy.

- Abstract
- Reports results of a study of the needs of management researchers in relation to their consumption and use of information. A profile of the management researcher was drawn up based on a questionnaire survey of the views of 404 researchers, mostly at PhD level, studying at 53 different institutions in the UK. Results highlighted the importance of periodicals and the English language orientation of researchers, who appear to place little significance on continental European literature as a contribution to the resolution of their research problems

- Abstract
- Reports a study of undergraduate students' use of computer-based information retrieval services in relation to their cognitive and learning styles. Includes a survey of staff at Sheffield University, UK on their use of computer databases and the extend to which undergraduates are made aware of these services. Results show that undergraduate use is low and varies greatly between students of differnt faculties. Student searching behaviour was found to be basic and their performance inadequate. Significant correlation's between cognitive and learning styles and search behaviour were found. Computer-assisted learning (CAL) packages were developed and customised for 3 departments. Guidelines were drawn up based on the project's findings for introducing a computerised information sources programme into the undergraduate curriculum and preparing CAL teaching packages on information skills

- Abstract
- Policy paper prepared by the Centre for Communication and Information Studies, Westminster University, London, for the British Library Board. Reports the results of a study of changes in the provision of electronic information to end users in UK academic libraries, conducted by the Centre for Communication and Information Studies, Westminster University, during the period 1988 to 1992. The period has seen a shift in expenditure from external online information services to CD-ROM, with over 70% of universities either planning or running local CD-ROM networks. There is some evidence of a modest amount of media substitution from printed information services to electronic, including a decline in online expenditure. The Bath Information and Data Service end user service has had a similar impact on alternative access media. The commercial online host market has eluded the end user market, being the most exclusive reserve of librarian mediators. Questions arising from the study include: how appropriate to the users' needs are the new networked services; what feedback and evaluation procedures are required; what is the nature of the support role of libraries in these changing circumstances; what additional resources; how and by whom are end user services to be financed; and how is wider access to database services impacting on ancillary services such as document delivery? In response, CCIS has formulated a research programme to extend the current quantitative work in the area of evaluating end user needs, activities and preferences in relation to information sources

- Abstract
- SummIt-BMT (Summarize It in Bone Marrow Transplantation) - das Zielsystem des Projektes - soll Ärzten in der Knochenmarktransplantation durch kognitiv fundiertes Zusammenfassen (Endres-Niggemeyer, 1998) aus dem WWW eine schnelle Informationsaufnahme ermöglichen. Im bmbffinanzierten Teilprojekt, über das hier zu berichten ist, liegt der Schwerpunkt auf den klinischen Fragestellungen. SummIt-BMT hat als zentrale Komponente eine KMT-Ontologie. Den Systemablauf veranschaulicht Abb. 1: Benutzer geben ihren Informationsbedarf in ein strukturiertes Szenario ein. Sie ziehen dazu Begriffe aus der Ontologie heran. Aus dem Szenario werden Fragen an Suchmaschinen abgeleitet. Die Summit-BMT-Metasuchmaschine stößt Google an und sucht in Medline, der zentralen Literaturdatenbank der Medizin. Das Suchergebnis wird aufbereitet. Dabei werden Links zu Volltexten verfolgt und die Volltexte besorgt. Die beschafften Dokumente werden mit einem Schlüsselwortretrieval auf Passagen untersucht, in denen sich Suchkonzepte aus der Frage / Ontologie häufen. Diese Passagen werden zum Zusammenfassen vorgeschlagen. In ihnen werden die Aussagen syntaktisch analysiert. Die Systemagenten untersuchen sie. Lassen Aussagen sich mit einer semantischen Relation an die Frage anbinden, tragen also zur deren Beantwortung bei, werden sie in die Zusammenfassung aufgenommen, es sei denn, andere Agenten machen Hinderungsgründe geltend, z.B. Redundanz. Das Ergebnis der Zusammenfassung wird in das Frage/Antwort-Szenario integriert. Präsentiert werden Exzerpte aus den Quelldokumenten. Mit einem Link vermitteln sie einen sofortigen Rückgriff auf die Quelle. SummIt-BMT ist zum nächsten Durchgang von Informationssuche und Zusammenfassung bereit, sobald der Benutzer dies wünscht.

- Abstract
- After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.
