- 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 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.

- Abstract
- The development of a given discipline in science and technology often depends on the availability of theorie capable of describing the processes which control the field and of modelling the interactions between the processes. The absence of an accepted theory of information retrieval has benn blamed for the relative disorder and the lack of technical advances in the area. The main mathematical approaches to information retrieval are examined in this study, including both algebraic and probabilistic models, and the difficulties which impede the formalization of information retrieval processes are described. A number of developments are covered where new theoretical understandings have directly led to the improvemenet of retrieval techniques and operations

- Abstract
- A summary of a survey of the use of the DDC in libraries of the United States and Canada is presented. (5% of alle libraries in the United States and Canada use DDC; of these are at least 75% use the most recent full or abridges edition. Librarians wish to have DDC revised continuously, but they do not want the meanings of numbers changed. Any assistance that can be provided in the application of DDC is welcome. Most of the larger libraries do not believe zhat the current index provides sufficient assistance. Divisions needing revision are listed with an index number reflecting priority. DDC is seen to be warmly regarded by librarians in general and by public service librarians in particular

- 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
