    Abstract
    Concept systems are not only used in the sciences, but also in secondary supporting fields, e.g. in libraries, in documentation, in terminology and increasingly also in knowledge representation. It is suggested that the development of concept systems be based on semantic analysis. Methodical steps are described. The principle of morpho-syntactic composition in semantics will serve as a theoretical basis for the suggested method. The implications and limitations of this principle will be demonstrated

    Abstract
    The information retrieval problem is described starting from an analysis of the concepts 'user's information request' and 'information offerings of texts'. It is shown that natural language phrases are a more adequate medium for expressing information requests and information offerings than character string based query and indexing languages complemented by Boolean oprators. The phrases must be represented as concepts to reach a language invariant level for rule based relevance analysis. The special type of representation called advanced thesaurus is used for the semantic representation of natural language phrases and for relevance processing. The analysis of the retrieval problem leads to a symmetric system structure
