- Abstract
- Traditionally, database indexing and book indexing have been looked upon as being quite distinct and have been kept apart in textbooks and teaching. The traditional borderline between both variations of indexing, however, should not conceal fundamental commonalities of the two approaches. For example, theausurus construction and usage, quite common in databases, has hardly been encountered in book indexing so far. Database indexing, on the other hand, has hardly made use of subheadings of the syntax-displaying type, quite common in book indexing. Most database users also prefer precombining vocabulary units and reject concept analysis. However, insisting on precombining descriptors in a large database vocabulary may, in the long run, well be destructive to the quality, of indexing and of the searches. A complementary approach is conceivable which provides both precombinations and analyzed subjects, both index language syntax and subheadings, and provides access to an information system via precombinations, without jeopardizing the manageability of the vocabulary. Such an approach causes considerable costs in input because it involves a great deal of intellectual work. On the other hand, much time and costs will be saved in the use of the system. In addition, such an approach would endow an information system with survival power

- Abstract
- Contemporary information systems, both the private and the commercially available ones, have often been blamed for their low effectiveness in terms of precision and recall, especially when they have reached considerable size with respect to file volume and use frequency (see, for example, Belkin, 1980; Blair, 1996, p.19; Desai, 1997; Drabenstott, 1996; Knorz, 1998). Saracevic (1989), after having reviewed the contemporary design of online subject access, calls "for radically different design principles and implementation" (p. 107). Van Rijsbergen (1990) writes: "The keywords approach with statistical techniques has reached its theoretical limit and further attempts for improvement are considered a waste of time" (p. 111). Lancaster (1992) deplores that very little really significant literature an subject indexing has been published in the last thirty or so years. In her preface to the Proceedings of the Sixth International Study Conference an Classification Research in 1997, Mcllwaine (1997) writes, "many were surprised to find that the problems with which they wrestle today are not greatly different from those that have been occupying the minds of specialists in the field for over a generation, and probably a great deal longer" (p. v).

- This article introduces a series of 8 papers giving a survey of the decisions to be made in the choice of the most expedient indexing method and presenting a short description of the contents of each of the papers, namely: the definability of the requested information; individual vs. generic concepts; the predictibility of their mode of expression; the fidelity of concept representation: the indexing language vocabulary; the indexing language grammar; the category-controlled interplay between vocabulary and grammar in an indexing language; the practice of information supply: the personal file; the employment of a large indexing language vocabulary; eth employment of an indexing language syntax

- Abstract
- Contemporary research in information science has concentrated on the development of methods for the algorithmic processing of natural language texts. Often, the equivalence of this approach to the intellectual technique of content analysis and indexing is claimed. It is, however, disregarded that contemporary intellectual techniques are far from exploiting their full capabilities. This is largely due to the omission of vocabulary categorisation. It is demonstrated how categorisation can drastically improve the quality of indexing and classification, and, hence, of retrieval

- Abstract
- The comparative evaluation of different mechanized information systems continues to constitute a controversial topic in the literature. Diametrically differemt opinions, seemingly corroborated through empirical evidence, have been presented since the time of the Cranfield experiments. For literally anything an empirical 'proof' can be submitted provided that suitable examples are selected and methods are chosen. substantial advance in Library and Information Science requires abandoning empiricism. Budd's 'hermeneutic phenomenoloy' seems to constitute a promising substitute

- Abstract
- Both classification systems and thesauri have their specific strengths and weaknesses. Through properly combining both approaches one can eliminate the latter and largely preserve the strenghts. 'Classauri' which originate in this well-known way are most effective if they are constructed and applied during computer-aided indexing. A special variety of classaurus is described which is characterized by the employment of simple bur highly effective conceptual and technical devices and by the renunciation of attempts to generate the wording of index entries algorithmically

- Abstract
- The tight adherence to dogmas, created and advocated by authorities and disseminated through hearsay, constitutes an impediment to the progress badly needed in view of the low effectiveness of the vast majority of our bibliographic information systems. The Italian mathematician and physicist Galileo has become famous not only for his discoveries but also for his being exposed to the rejective and even hostile attitude on the part of his contemporaries when he contradicted several dogmas prevailing at that time. This obstructive attitude can be traced throughout the centuries and manifests itself in the field of modern information science, too. An example is the allegedly necessary, inevitable precision/recall relationship, as most recently postulated again by Lancaster (1994). It is believed to be confirmed by emprical evidence, with other empirical evidence to the contrary being neglected. This case even constitutes an example of the suppression of truth in the interest of upholding a dogma

- Abstract
- The human's expressing general concepts in uncontrolled natural language, his information need, and meaning recognition in and essence selection from texts are indeterminate processes and therefore defy any satisfactory formalization and programming. Where the equivalence or even superiority of algorithmic approaches to these golas has been claimed, the authors have worked under artificial, experimental conditions and/or have in their evaluation referred to those approaches that are far from exploiting the capabilities of intellectual content analysis, representation and query phrasing

- Abstract
- The contents of scientific and technical handbooks often needs fast, reliable and precise subject access, even if the searcher is not familiar with the terminology of the book and has not read it beforehand. This requires careful and expert subject indexing in a highly specific indexing vocabulary, as well as the presentation of the resulting index in a lucid, conceptually transparent manner in print and on disk. Index users, when looking up a general subject heading, often ignore the necessity of looking up the appertaining hierarchically subordinate, more specific subject headings, too. They are either not made aware of these subject headings or their use is felt to be too cumbersome. A classifies approach to computerized subject indexing is described which resembles Ranganathan's Classified Catalogue. Through a variety of peculiarities it leads the searcher rapidly and easily to all subject headings related to a primarily chosen one, and to the postings under all these headings
