- 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

- 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).

- Abstract
- Natural text phrasing is an indeterminate process and, thus, inherently lacks representational predictability. This holds true in particular in the Gase of general concepts and of their syntactical connectivity. Hence, natural language query phrasing and searching is an unending adventure of trial and error and, in most Gases, has an unsatisfactory outcome with respect to the recall and precision ratlos of the responses. Human indexing is based an knowledgeable document interpretation and aims - among other things - at introducing predictability into the representation of documents. Due to the indeterminacy of natural language text phrasing and image construction, any adequate indexing is also indeterminate in nature and therefore inherently defies any satisfactory algorithmization. But human indexing suffers from a different Set of deficiencies which are absent in the processing of non-interpreted natural language. An optimally effective information System combines both types of language in such a manner that their specific strengths are preserved and their weaknesses are avoided. lf the goal is a large and enduring information system for more than merely known-item searches, the expenditure for an advanced index language and its knowledgeable and careful employment is unavoidable.

- Abstract
- 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
