- Abstract
- In this lecture I intend to challenge those who uphold a monist or even a dualist view of the universe; and I will propose, instead, a pluralist view. I will propose a view of the universe that recognizes at least three different but interacting sub-universes.

- Abstract
- The complexity explosion has led to ever-increasing difficulties in subject specification, especially in the use of notations in classified arrangement. Two recent developments, the use of DC18 and PRECIS in the BNB, form a substantial contribution towards the solution of these difficulties, particularly in view of the increased pressure for standardization arising from the use of computers

- Abstract
- Different kinds of syntactic tools of information languages (IL) in use, considered as meaning-distinguished tools, are described as simplified forms of some initial IL grammar tools called 'standard phrases' which are n-place relational predicates of a special kind. A quantitative evaluation is attempted of the effects which the idiosyncracies of the syntactic tools of IL's have on their semantic power

- Abstract
- This paper describes a method for automatically segmenting words into their stems and affixes. The process uses certain statistical properties of corpus (successor and predecessor letter variety counts) to indicate where words should be divided. Consequently, this process is less reliant on human intervention than are other methods for automated stemming. The segmentation system is used to construct stem dictionariesfor documnet classification. Information retrieval experiments are then performed using documents and queries so classified. Results show not only that this method is capable of high quality word segmentation, but also that its use in information retrieval produce results that are at least as good as thosse obtained using the more traditional stemming process.

- Abstract
- An automatic classification technique has been developed, based on the character structure of words. Dice's similarity coefficient is computed from the number of matching diagrams in pairs of character strings, and used to cluster sets of character strings. A sample of words from a chemical data base was chosen to contain certain stems derived from the names of chemical elements. They were successfully clusterd into groups of semantically related words. Each cluster is characterised by the root word from which all its members are derived. A second example of titles from Mathematical Reviews was clustered into well-defined classes, which compare favourably with the subject groupings of Mathematical Reviews

- Abstract
- Previously, documentation systems have suffered from the use of descriptors insufficiently keyed to colloquial language ot from the seemingly insoluble problem of automatically processing original texts. The aim is to combine interlinguistic cooperation in literature documentation with special conditions of non-numeric data processing, without having to develop a special standardised documentation language. In 1975 work began on abstracting some American and European journal articles on educational technology using the constructed language Esperanto. The resulting collection of abstracts is being used by the FEoLL Institut für Kybernetische Pädagogik, Paderborn, to develop a conversational system for the retrieval of answers and references

- Abstract
- The use of weights to denote a query representation and/or the indexing of a document is analysed as a generalization of a Boolean retrieval system. Criteria are given for the functions used to evaluate the relevance of the records to a specific query, including self-consistency. Various mechnaisms suggested in the literature for evaluating the relevance of records with regard to a given query are tested and found to be less than satisfactory. A new approach is suggested to avoid some of the perils of a weighted Boolean retrieval system

- Abstract
- Many retrievalexperiments are intended to discover ways of improving performance, taking the results obtained with some particular technique as a baseline. The fact that substantial alterations to a system often have little or no effect on particular collections is puzzling. This may be due to the initially poor seperation of relevant and non-relevant documents. The paper presents a procedure for characterizing this seperation for a collection, which can be used to show whether proposed modifications of the base system are likely to be useful.
