    Abstract
    Most systems for term associations are statistically based. In general they exploit term co-occurrences. A critical overview about statistical approaches in this field is given. A new approach on the basis of a linguistic analysis for large amounts of textual data is outlined

    Abstract
    REALIST (Retrieval Aids by Linguistics and Statistics) is a tool which supplies the user of free text information retrieval systems with information about the terms in the databases. The resulting tables of terms show term relations according to their meaning in the database and form a kind of 'road map' of the database to give the user orientation help

    Abstract
    Problems of indexing and searching free-text data bases are discussed in detail. The possibilities and limitations of Boolean searching are shown. An experimental system COPSY (Context operator syntax) that was built in order to avoid common errors connected with Boolean search is outlined. This system permits, as input, any natural language search question formulation and yields, as output, documents ranked on the basis of an automatically calculated correspondence between natural language search questions and content-based analysis of documents. COPSY is part of a text processing project at Siemens AG called TINA (Text-Inhalts-Analyse...). Software from TINA is actually being applied and evaluated by the US Department of Commerce for patent searching and indexing.
