Prolog type inference
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 Web•Prolog (PROgramming in LOGic) represents programs as logical Horn clauses and treats execution as answering queries with backward chaining. •Production system languages (OPS5, CLIPS) represent programs as rules that add and/or delete elements from working memory and treat execution as forward chaining inference. 3 Prolog

WebThe goal of this assignment is to write a type inference algorithm similar (but simpler) than the one in OCaml/Haskell in SWI prolog. In particular, this program figures out the types of inputs and outputs of functions and type of variables used much like OCaml/Haskell inferes types when it compiles code.
