    Abstract
    The convertibility of ordering systems such as thesauri and classification schemes have been investigated for many years. The focus has so far been more on thesauri than on classification schemes. Classification schemes too could differ from one another in several ways: in their structural, semantic, lexical and notational features. These incompatibilities make multiple catalog search difficult for the users. The DDC is one of the widely used schemes worldwide that encompasses all of knowledge whereas the Mathematics Subject Classification schem published by the American Mathematical Society is a special classification scheme that is used in several AMS publications, notably the Mathematical Review. An interface that enables mathematicians to access library collections organized with the DDC, using the AMS scheme as an interface will certainly by useful. This paper suggests a prototype expert system interface to map the MSC scheme on to the mathematics (510 schedule of DDC20) and presents the work done so far towards this end. Compares the 2 schemes and discusses the mapping strategies/rules developed and the features of the prototype expert system design

    Abstract
    Reports on an exploratory study of the semantic interpretation of conjuncts and their translation into Boolean search statements, using dictionary definitions. Rules were formulated based on syntactic and semantic analysis of the conjunctive phrases occuring in 160 natural language statements (NLS) of users information needs. This includes a set of transformational rules to accomodate variations in natural language expressions. Evaluation of the rules to accomodate variations in natural language expressions. Evaluation of the rules was performed by matching the output of the algorithm with the search formulation done by an expert online searcher. It resulted in an 81% match rate
