1Mettrop, W. ; Nieuwenhuysen, P.: Internet search engines : fluctuations in document accessibility.
In: Journal of documentation. 57(2001) no.5, S.623-651.
Abstract: An empirical investigation of the consistency of retrieval through Internet search engines is reported. Thirteen engines are evaluated: AltaVista, EuroFerret, Excite, HotBot, InfoSeek, Lycos, MSN, NorthernLight, Snap, WebCrawler and three national Dutch engines: Ilse, Search.nl and Vindex. The focus is on a characteristics related to size: the degree of consistency to which an engine retrieves documents. Does an engine always present the same relevant documents that are, or were, available in its databases? We observed and identified three types of fluctuations in the result sets of several kinds of searches, many of them significant. These should be taken into account by users who apply an Internet search engine, for instance to retrieve as many relevant documents as possible, or to retrieve a document that was already found in a previous search, or to perform scientometric/bibliometric measurements. The fluctuations should also be considered as a complication of other research on the behaviour and performance of Internet search engines. In conclusion: in view of the increasing importance of the Internet as a publication/communication medium, the fluctuations in the result sets of Internet search engines can no longer be neglected.

2Nieuwenhuysen, P. ; Vanouplines, P.: Document plus program hybrids on the Internet and their impact on information transfer.
In: Online and CD-ROM review. 22(1998) no.2, S.55-72.
Abstract: Examines some of the advanced tools, techniques, methods and standards related to the Internet and WWW which consist of hybrids of documents and software, called 'document program hybrids'. Early Internet systems were based on having documents on one side and software on the other, neatly separated, apart from one another and without much interaction, so that the static document can also exist without computers and networks. Documentation program hybrids blur this classical distinction and all components are integrated, interwoven and exist in synergy with each other. Illustrates the techniques with particular reference to practical examples, including: dara collections and dedicated software; advanced HTML features on the WWW, multimedia viewer and plug in software for Internet and WWW browsers; VRML; interaction through a Web server with other servers and with instruments; adaptive hypertext provided by the server; 'webbots' or 'knowbots' or 'searchbots' or 'metasearch engines' or intelligent software agents; Sun's Java; Microsoft's ActiveX; program scripts for HTML and Web browsers; cookies; and Internet push technology with Webcasting channels
3Nieuwenhuysen, P. ; Vanouplines, P.: International training courses on the retrieval and management of information in science and technology.
In: Information development. 13(1997) no.1, S.23-26.
Abstract: Details the training courses on information retrieval in science and technology for information professionals from developing countries, offered by the Free University of Brussels, Belgium. The course was slanted towards the subject area of water and the environment as well as the application of computers and networks. Discusses the aims of the courses, subjects treated, teachers and contributors, participants, costs and financial aspects, sponsors, methods used to announce the courses, problems encountered and lessons learned. Mentions possible future programmes
4Tegenbos, J. ; Nieuwenhuysen, P.: My kingdom for an agent? : Evaluation of Autonomy, an intelligent search agent for the Internet.
In: Online and CD-ROM review. 21(1997) no.3, S.139-148.
Abstract: Evaluates a range of commercially available software designed to act as intelligent search agents to assist users find materials of interest on the Internet and WWW or selects for them without asking. Notes that existing search engines can be useful in finding information but their different features and sometimes unfriendly interfaces can be confusing and intelligent search agents may be able to overcome these difficulties. Singles out one package: Autonomy; from Autonomy Corporation, describes its specific features and reports results of a test conducted with the software. Concludes that, from the test results, Autonomy is not yet ready to challenge the existing Internet search engines, which in the tests performed better than Autonomy with regard to recall and precision of information retrieval. Autonomy did not give enough feedback to control the search action
5Smet, E.d. ; Nieuwenhuysen, P.: ¬The DANIS database system : integrating bibliographic and factual information using CDS/ISIS software and the Common Communication Format.
In: Journal of information science. 23(1997) no.4, S.327-337.
Abstract: Presents the Danube Information System (DANIS): a database containing records on documents, persons, organizations, projects, events and standrads relevant to the management of the Environmental Programme on the Danube River Basin. Describes briefly the background ideas for an integrated bibliographic / factual system based on the CDS/ISIS software and the Common Communication Format (CCF), along with the development activities of the system, such as training workshops and expert meetings. Includes a brief account of the present state of the art of the project, including the actual management set up and Internet and WWW presence. Technical aspects of DANIS are highlighted, such as the enrichment of the system by the data entry and searching interfaces and the technical solutions introduced to cope with the integrated approach in both indexing and display formats

8Nieuwenhuysen, P.: Computerised storage and retrieval of structured text information : CDS/ISIS version 2.3.
In: Program. 25(1991) no.1, S.1-18.
Abstract: The computer software package CDS/ISIS is suitable for the storage and retrieval of structured, text-oriented information, such as bibliographic descriptions. Versions exist for various hardware including IBM microcomputers and compatibles. The software is very attractive, mainly because it is powerful and because the producer, Unesco, normally fulfils requests to use it for free. Micro CDS/ISIS is reviewed in this paper which includes recent experience with version 2.3
