- Abstract
- At Rotterdam Ports Authority in the Netherlands the Habour information database includes a press cuttings service and various online databases. To enable research staff to have direct access to information the POINT (Point Information Net) was begun in 1993. Using Verity software POINT provides simultaneously full text searching on a range of databases. The software uses current Web indexing technqiues to overcome the problems of excessive recall and low precision. A key element is the system's ability to recognise word combinations

- Abstract
- A study of new information systems and databases shows that insufficient help is provided to enable users to exploit these resources adequately. Despite surveys which show that users rarely employ Boolean logic appropriately in formulating search strategies database producers continue to use it as an indexing tool. Moreover, although much effort has been devoted to developing navigation techniques to search databases, problems still arise with insufficient entry points and links between systems. Resources are currently being channelled into the development of virtual reality systems to help users

- Abstract
- At Rotterdam Port Authority an information database has been created with approx. 100.000 full text documents online. Topic software has been used to identify word groups and refine search strategies to optimize precision and recall. The software guides users from selected terms to other relevant word combinations. Although the system would benefit from further refinement, users are generally satisfied. The database includes a number of foreign language documents but lacks a thesaurus of foreign terms

- Abstract
- Modern online information systems have been criticized as being too complicated for the average information seeker. To overcome this problem interfaces have been developed to assist users at all stages of the information transfer process from searching to analysis and evaluation of retrieval data. However, the effectiveness of an interface will depend on the skills of the user. Further development of interfaces will be aided by the use of Windows and mouse controlled systems

- Abstract
- A recent survey at the Royal Library in the Netherlands showed that subject headings are more efficient than title keywords for retrieval purposes. 475 Dutch publications were selected at random and assigned subject headings. The study showed that subject headings provided additional useful information in 56% of titles. Subsequent searching of the library's online catalogue showed that 88% of titles were retrieved via subject headings against 57% through title keywords. Further precision may be achieved with the help of indexing staff, but at considerable cost

- Abstract
- In the Netherlands the Gemeenschappelijke Onderwerps Ontsluiting (Standard Subject Indexing) schedules were developed for libraries using the national online catalogue. At Leiden University's Institute voor Oost-Europees Recht en Ruslandkunde use of both UDC and GOO schedules enabled a comparison to be made of the systems. A study of approx. 1.400 titles showed that GOO was more effective in retrieving relevant documents, whereas UDC was more suited for compiling subject bibliographies. The best of both schemes should be combined for optimal retrieval

- Abstract
- Existing classification systems require constant expansion to accomodate new subject fields, while subject indexing techniques fail to display the relationship of subjects. Relational databases are currently being developed which will guide users through the differing levels of subjects, using the 'cartography of science'. Such developments will enable librarians to play a more interactive role in information retrieval and will have far-reaching consequences on the design of subject-indexing systems

- Abstract
- 1st in a series or reports by the IRT (Internet Retrieval Tools) Working Party in the Netherlands. The group was formed at the start of 1997 to attempt to identify which search engines were most suitable for different ypes of enquiries. Compilers of search engines frequently give little information about the data covered by their service and how their service deals with metadata. Preliminary tests show considerable variations in approach; future tests will examine the use of ranking and currency of systems

- Abstract
- Many companies now recognise the importance of knowledge as a factor in ensuring the organisation's success. Such organisations will create a knowledge infrastructure linking all aspects of the process, such as knowledge creation, dissemination, storage and application. This infrastructure will involve staff, processes and systems from a range of areas within the organisation. Trained information professionals can expect to play an important role in such services. The limitations of indexing services for online databases will require the input of information specialists in undertaking specialised searches

- Abstract
- On 19 Aug 94 a group of readers' advisers met to discuss their problems in Utrecht Provincial Central Library in the Netherlands. The panel felt that too much emphasis had been placed on libraries' information role and that more effort should be devoted to recreational reading through organising lectures and reading groups. It was felt that training sessions should be organised and a network created for the exchange of ideas

- Abstract
- The proliferation of electronic databases and reduced library collections require researchers to be familiar with an increasing range of bibliographical resources. To assist users in searching multiple databases the PICA network in the Netherlands has developed PiCarta as a single information source. The servie enables users to access bibliographical databases and electronic journals using Boolean logic, fuzzy operators, and subject weighting. The system is, however, dependent upon indexing methods used in original sources

- Abstract
- At Limburg Provincial Central Library and Information Service in the Netherlands the online public catalogue has been replaced by a new system, Foundation. The OPAC network was an automated version of the card catalogue, whereas Foundation has been developed entirely from scratch. The system runs on Windows software and assists even inexperienced users to formulate suitable search strategies. The system accepts online catalogue records from other sources and has attracted considerable intersts from several areas, including the publishing industry

- Abstract
- Although the librarian in an industrial concern is ideally located at the forefront of information technology, many industrial librarians view their collections as mere warehouse of information. Information is a primary resource and information management must be recognised as an important element within the company. The information manager is responsible for identifying the company's information needs and the implementation of an information strategy. The information manager should follow 6 basic concepts: actuality, availability, accessibility, retrievability, deliverabiblity and usability
