Also typical areas of application are mentioned. As literature on knowledge representation formalisms [Frost 1986] can be recommended. Finally the realisation of formalisms is discussed. 7.1 Logic formalisms A logic formalism contains (cf. Frost 1986] 1. A well defined language for representing knowledge. 2.

....Future Work 11 7.1 Phase II of PEST : 11 7. 2 Explanation Facilities : 12 KBSI ES 93 3 1 Introduction In this paper we address the issues involved in developing a knowledge based system (KBS) Jac90] [Fro86] for constructing promotions of various kinds of produce within supermarkets [R.J89] We are currently working with a large retail company which supplies both expertise and sample data. Specifically, the system under development is to be used to determine the promotional layout and worth of ....

....that can be explicitly deduced from the knowledge base. Consequently, both assumptions yield different answers that have to be interpreted differently. Types of Queries With the above notations we are now able to define the two principle types of queries, i.e. closed query and open query, cf [Fro86] Closed queries are queries whose contents are either sentences or closed concepts. Vice versa, open queries are queries whose contents are formulas or open concepts. If jjCjj KBS x where x 2 fOWA;CWAg is a query and C is the content of a closed query we can define the according answers as ....

....in AI and database literature where knowledge base system is used synonymously with expert system. It is not our intention to engage in a detailed discussion of the nature of knowledge base systems in this section. There have been a number of attempts to address specifically this issue (e.g. Fro86, Ull88, Wie84, Wie86] In [ Ozs89] we give the following working definition which we will adopt here as well. A knowledge base is a structured collection of ffl data representing facts about some aspects of a domain of discourse that is being modeled (sometimes called the extensional database ....
....secret can be processed by the KBMS using its reasoning capabilities to produce the answer Yes. The clear separation of the intensional and the extensional databases is, of course, the more difficult problem. We avoid that discussion in this chapter and, instead, refer the reader to [Wie86, Fro86] 2.2 Object Oriented KBMS Organization The architecture of a KBMS that provides the features mentioned above has been discussed for some time. There have been attempts at coupling expert systems with a traditional DBMS. In such designs, the extensional database is maintained by a traditional ....
