    Abstract
    The suggestion that classifications for retrieval should be constructed automatically raises some serious problems concerning the sorts of classification which are required, and the way in which formal classification theories should be exploited, given that a retrieval classification is required for a purpose. These difficulties have not been sufficiently considered, and the paper therefore attempts an analysis of them, though no solution of immediate application can be suggested. Starting with the illustrative proposition that a polythetic, multiple, unordered classification is required in automatic thesaurus construction, this is considered in the context of classification in general, where eight sorts of classification can be distinguished, each covering a range of class definitions and class-finding algorithms. The problem which follows is that since there is generally no natural or best classification of a set of objects as such, the evaluation of alternative classifications requires either formal criteria of goodness of fit, or, if a classification is required for a purpose, a precises statement of that purpose. In any case a substantive theory of classification is needed, which does not exist; and since sufficiently precise specifications of retrieval requirements are also lacking, the only currently available approach to automatic classification experiments for information retrieval is to do enough of them

    Abstract
    Any classification describes some structure of taxons on a subject field. Thus, one of the natural aspects of a classification theory is the study of possible taxon structure types. In particular, two classifications generating isomorphic taxon structures (regardless of size or how filled they are) could quite rightly be said to be of the same type. Let us formulate this situation in precise terms. Assume M is the subject field of the classification (the class of all objects to be classified). We use T to denote the set of taxon subclasses identified by the classificational features. On taxon set T the is a natural order of inclusion

    Abstract
    What is interesting in natural language semantics is not so much the class of referents of a term at any particular point in time but rather the dynamics by which this set is changed. In particular, linguists today are intrigued by the interaction of speakers - the mechanism of dialogue. The interesting thing about classification is not that it yields a precise way of using terms derived from a natural language but that it is essentially a different thing than a natural language. The fact that artificially constructed classes may - and should - have names rather than code symbols as identifiers may confuse this issue
