Abstract: Natural Expert is a product that allows users to build knowledge based systems. It uses a lazy functional language, Natural Expert Language, to implement backward chaining and provide a reliable knowledge processing environment in which development can take place. Customers from all over the world buy the system and have used it to handle a variety of problems, including applications such as airplane servicing and bank loan assessment. Some of these are used 10,000 times or more per month. 1... (Update)

.... embedded in a system of unique types as in Clean [NSvP91, Ach96] In the commercial non strict functional programming language Natural EL [HNSSH97] these interactions were implemented as direct calls. The intention of this paper is twofold: On the one hand a non deterministic...

...was a trade secret. Natural Expert is an expert system shell marketed by Software AG, which interfaces to a database system called Natural [3]. Users write shell programs in a language similar to Haskell. Lazy evaluation is essential to manage interaction with the database,...
