F.A. Grootjen, and Th.P. van der Weide. Conceptual Relevance Feedback. In: Proceedings of the 2002 IEEE International Conference on Systems, Man and Cybernetics, (NLPKE 2002), October, 2002.

Capturing the user's information need may be seen as a major challenge search engines are confronted with. This paper proposes a way to interpret the results of a user's initial query. This is done by positioning this preliminary result into a semantical structure called concept lattice. The resulting substructure is used for relevance feedback.

Reports

H. Bosma. Requirements. Technical report: ArchiMate/D4.1, December, 2002.

his document contains the general requirements for the ArchiMate project set by the participating organisations ABP, ABN AMRO and the Belastingdienst. This document is assembled from the ArchiMate deliverables D4.1.1 to D4.1.3 containing the partner-specific requirements. The requirements are prioritised and related to the partner-specific requirements.

F.A. Grootjen, and Th.P. van der Weide. Conceptual Query Reformulation. Technical report: NIII-R0202, Computing Science Institute, University of Nijmegen, 2002.

One of the biggest challenges of search engines is to capture the user's information need. This paper proposes a way to interpret the results of a user's initial query. This is done by positioning the preliminary result into a semantical structure called concept lattice. The gathered conceptual information can be used for relevance feedback in subsequent searches.

H.A. (Erik) Proper. PRONIR proposal. Technical report, Nijmegen Institute for Information and Computing Sciences, University of Nijmegen, Nijmegen, The Netherlands, EU, 2002, NWO Project Proposal.

The knowledge and information resources we need to conduct our activities in daily life, be it at work or at home, are increasingly available in some electronic form by way of the Internet. Some examples of such resources are: documents, people (by their e-mail or chat addresses), document collections, objects and facts in databases and even entire applications. People in search of knowledge turn to the Internet with the aim of finding relevant knowledge or information that will support them in executing their tasks. This research project aims to develop a theory, and demonstrate its validity by means of a prototype system, for profile based retrieval of heterogeneous networked resources.

H.A. (Erik) Proper, and S.J.B.A. (Stijn) Hoppenbrouwers. Information System Evolution as Language Evolution. Technical report: NIII-R0205, Nijmegen Institute for Information and Computing Sciences, University of Nijmegen, 2002.

In this article we look at the evolution of information systems from the perspective of the evolution of domain languages, and provide a report on some of our ongoing research activities.

Many if not all analysis and design approaches for information systems base themselves on techniques involving some sort of natural language analysis. However, the view on language underlying these approaches ignores several issues concerning the nature of language.

This article primarily aims to create awareness for the issues at play, and argues that current approaches ignore most of them. We finish by presenting an overview of our research efforts concerning the tackling of the matters discussed.

W.-J. van den Heuvel, and H.A. (Erik) Proper. De pragmatiek van Architectuur. In: Informatie, Nr: 11, Vol: 44, Pages: 12-14, 2002, In Dutch.

Modelleermethoden, representatietalen en standaardisatie droegen de laatste jaren bij aan de betekenis van het concept architectuur. De pragmatiek van architectuur is tot nu toe onvoldoende belicht gebleven. In dit artikel wordt vanuit een pragmatisch perspectief naar architectuur gekeken.

De IEEE-standaard 1471 bevat drie concepten waarmee orde wordt geschapen in de jungle van architectuurraamwerken. De auteurs doen een voorzet voor een contingentiemodel, voor het consistent en effectief toepassen van een raamwerk. Hiervoor dragen zij een aantal aspecten aan: scope, tijdhorizon, levenscyclusfase, abstractieniveau en domein.
