WebDec 21, 2014 · 1 I am trying to build an inference engine in prolog. For example, here are some rules R1 : A and B -> C R2 : E and F -> D R3 : G and T -> H I wanted to do it like this c : … WebProlog is a weakly typed language with dynamic type checking and static scope rules. Prolog is typically used in artificial intelligence applications such as natural language interfaces, automated reasoning systems and expert systems. Expert systems usually consist of a data base of facts and rules and an inference engine, the run time system of
Type and mode checking in prolog (part 1): type_check
http://galois.com/wp-content/uploads/2014/07/pub_AT_AutomaticTypeInference.pdf WebThe Inference mechanism of the Prolog is based on Robinson’s Resolution Principle, that was proposed in 1965, and Answer extracting mechanism by Green (1968). These ideas came together forcefully with the advent of linear resolution procedures. michael stern phd
2 Using Prolog
WebJan 1, 2015 · Robin Milner, Roger Hindley, and Luis Damas all contributed to this powerful polymorphic type inference system. This chapter develops a polymorphic type inference system for the Small language using Prolog as the implementation language. A typical way to describe type inference is with type inference rules. WebProlog has a built-in backward chaining inference engine which can be used to partially implement some expert systems. Prolog rules are used for the knowledge representation, and the Prolog inference engine is used to derive conclusions. Other portions of the system, such as the user interface, must be coded using Prolog as a programming language.
