    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

    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
    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 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 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
    The low effectiveness of most current information systems has often been pointed out and deplored. A number of misconceptions and experiments under unrealistic conditions have contributed to the faulty design and evaluation of information systems. The postulate of representational predictibility can help to clarify some of the still pending issues as there are the strenghts and limitations of uncontrolled natural language text in retrieval systems, factors for their evaluation, the reliability, consistency, and exhaustivity of indexing, the postulated 'inverse precision-recall relationship', and the usefulness of syntactical evices. The performance of information systems can be imporved if representational predictibility is aimed at in their design and operational use

    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
    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 second Cranfield experiment (Cranfield II) in the mid-1960s challenged assumptions held by librarians for nearly a century, namely, that the objective of providing subject access was to bring together all materials an a given topic and that the achieving of this objective required vocabulary control in the form of an index language. The results of Cranfield II were replicated by other retrieval experiments quick to follow its lead and increasing support was given to the opinion that natural language information systems could perform at least as effectively, and certainly more economically, than those employing index languages. When the results of empirical research dramatically counter conventional wisdom, an obvious course is to question the validity of the research and, in the case of retrieval experiments, this eventually happened. Retrieval experiments were criticized for their artificiality, their unrepresentative sampies, and their problematic definitions-particularly the definition of relevance. In the minds of some, at least, the relative merits of natural languages vs. indexing languages continued to be an unresolved issue. As with many eitherlor options, a seemingly safe course to follow is to opt for "both," and indeed there seems to be an increasing amount of counsel advising a combination of natural language and index language search capabilities. One strong voice offering such counsel is that of Robert Fugmann, a chemist by training, a theoretician by predilection, and, currently, a practicing information scientist at Hoechst AG, Frankfurt/Main. This selection from his writings sheds light an the capabilities and limitations of both kinds of indexing. Its special significance lies in the fact that its arguments are based not an empirical but an rational grounds. Fugmann's major argument starts from the observation that in natural language there are essentially two different kinds of concepts: 1) individual concepts, repre sented by names of individual things (e.g., the name of the town Augsburg), and 2) general concepts represented by names of classes of things (e.g., pesticides). Individual concepts can be represented in language simply and succinctly, often by a single string of alphanumeric characters; general concepts, an the other hand, can be expressed in a multiplicity of ways. The word pesticides refers to the concept of pesticides, but also referring to this concept are numerous circumlocutions, such as "Substance X was effective against pests." Because natural language is capable of infinite variety, we cannot predict a priori the manifold ways a general concept, like pesticides, will be represented by any given author. It is this lack of predictability that limits natural language retrieval and causes poor precision and recall. Thus, the essential and defining characteristic of an index language ls that it is a tool for representational predictability.
