- 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.

- Abstract
- Discusses articles in which indexing of image collections receives virtually no mention and continues with comments about articles in which indexing receives special attention. Describes four major indexing systems: Library of Congress, AAT, ICONCLASS and TELCLASS. Discusses new indexing approaches where the use of descriptive words is being replaced by other methods of retrieval. Describes indexing by content (attempting to match an input image to a database collection) and by using a visual thesaurus. Raises questions about indexing for various kinds of collections and discusses indexing philosophy

- Abstract
- The study of subject access to UK academic library catalogues was based on a questionnaires end out during Summer 1991. 86 out of a possible 110 questionnaires were returned. All universities and polytechniques now have OPACs which are progressing well towards comprehensive bibliographical coverage of their libraries' stocks. The MARC format is now widely used. Subject access strategies are usually based on either Library of Congress Subject Headings or inhouse indexing systems but almost half the OPACs studies have no separate subject searching option based on subject indexing is expensive and future subject indexing strategies are best based on pre-existing controlled vocabularies. Strategies authority control is essential. A limited range of software strategies is recommended including the need to limit search results

- Abstract
- This technical report provides guidelines for the content, organization, and presentation of indexes used for the retrieval of documents and parts of documents. It deals with the principles of indexing, regardless of the type of material indexed, the indexing method used (intellectual analysis, machine algorithm, or both), the medium of the index, or the method of presentation for searching. It emphasizes 4 processes essential for all indexes: comprehensive design, vocabulary management, and the provision of systax. It includes definitions of indexes and of their parts, attributes, and aspects; a uniform vocabulary; treatment of the nature and variety of indexes; and recommendations regarding the design, organization, and presentation of indexes. It does not suggest guidelines for every detail or technique of indexing. These can be determined for each index on the basis of factors covered in the technical report

- Abstract
- Addresses the problems of content retrieval in the construction of pictorial database management systems. Presents a generalisable architecture for the effective identification of specific pictures from a large collection and describes prototype system based on this architecture successfully implemented. The architecture consists of 3 main components: picture description; picture indexing and filing, and picture retrieval. The description of pictures is facilitated by using the main semantic concepts employed in the entity-attribute-relationship model. The chief function of the picture indexing and filing component is to convert the logical representations into a relational data format to prepare for subsequent processing initiated by picture queries

- Abstract
- Report results of a survey of abstracting and indexing services, published in CD-ROM format, by a sample of 109 secondary service publishers. One of the main aims of the survey was to determine the impact that provision of secondary services as CD-ROM databases has had on other product printed and online formats, especially in terms of the generation of income. Confidential information regarding income from the 3 specific product formats was obtained from UK and US publishers of CD-ROM databases, for the years 1987 to 1992, with 1992 figures provided as an estimate. Presents a detailed breakdown, expressed as percentages of total income derived from each of the 3 formats, for 18 specific databases, grouped according to perceived migration characteristics. Other information includes: price comparison of the 3 product formats; use of third parties for CD-ROM production; lease and licensing agreements; and the implication for the UK research associations

- Content
- Backgrund to the study: The question of multilingual access to bibliographic databases affects not only searchers in countries in which several languages are spoken such as Switzerland, but also all those who search material in databases containing material in more than one language, which is the case in the majority of scientific or research databases. he growth of networks means that we can easily access catalogues outside our own immediate circle - in another town, another country, another continent. In doing so we encounter problems concerning not only search interfaces, but also concerning subject access or even author access in another language. In France for example, each document, independently of the language in which it has been written, is indexed using a French-language subject heading language. Thus, in order to search by subject headings for documents written in English or German, held in the Bibliothèque nationale de France, the researcher from abroad has to master the French language. In theory, the indexer should be able to analyse a document and assign headings in his/her native language, while the user should be able to search in his/her native language. The language of the document itself should have no influence on the language of the subject heading language used for indexing nor on the language used for searching. (Practically speaking of course, there are restrictions, since there is a limit to the number of languages in which subject headings languages could be maintained and thus in which the user may search.) In the example below, we are concerned with three languages: German, French and English. If we can imagine a system in which there are equivalents among subject headings in these three languages, the following scenario may be envisaged: a German-speaking indexer will use German-language subject headings to index all the documents received, regardless of the language in which they are written. The user may search for these documents by entering subject headings in German, but also in French or in English, thanks to the equivalents that have been established, in French or in English without the necessity to know the other languages or the structure of the other SHLs. Ideally, this approach should not be confined to one database, but would allow the different databases to be brought together in virtual system: an English-speaking user in London should be able to search the database of the Deutsche Bibliothek in Frankfurt using English-language headings, and retrieving documents which have been indexed using the German subject headings' list.
