- 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
- 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
