This paper describes the design of the information retrieval facilities of an integrated information system called EUROMATH. EUROMATH is an example of a Knowledge Worker Support System: it has been designed specifically to support mathematicians in their research work. EUROMATH is required to provide uniform retrieval facilities for searching in a user's personal data, in a shared database of structured documents and in public, bibliographic databases. The design of information retrieval facilities that satisfy these and other requirements posed several interesting design issues regarding the integration of various retrieval techniques. As well as a uniform query language, designed to be highly usable by the target user group, the retrieval facilities provide expert intermediary functions, i.e. sophisticated support for the retrieval of bibliographic data. This support is achieved using a model of the user, a model of the user's information need and a set of search strategies based on those used by human intermediaries. The expert intermediary facilities include extensive help facilities, automatic query reformulation and browsing of a variety of sources of query terms.

CAD Based - Manufacture of Parts is the application of math models or CAD techniques to Computer Aided Manufacturing. This paper will discuss the application and considerations for such a system, and the presentation will show examples of how this technique is used currently in several large companies and as it expands into the supplier and/or manufactured part market. The discussion will emphasize the importance of a single data base and the capability of tracing this information from engineering concept to finished part. The prime examples will be those used in the Automotive industries and will cover some historical background in Computer Aided Manufacturing and Numerical Control.
