Définition

La norme KIF pour l'échange de connaissances est un langage informatique formel conçu pour permettre aux systèmes à base de connaissances de partager et de réutiliser leurs connaissances. KIF est similaire aux langages comme Cycl, Flogic, KL-One, LOOM, et Ontolingua mais contrairement à ces langages, son rôle principal n'est pas l'expression ou l'utilisation des connaissances, mais simplement l'échange des connaissances entre systèmes. KIF a été créé par Michael Genesereth et Richard Fikes pour le DARPA.

Knowledge Interchange Format

Knowledge Interchange Format (KIF) is a computer language designed to enable systems to share and re-use information from knowledge-based systems. KIF is similar to frame languages such as KL-One and LOOM but unlike such language its primary role is not intended as a framework for the expression or use of knowledge but rather for the interchange of knowledge between systems. The designers of KIF likened it to PostScript. PostScript was not designed primarily as a language to store and manipulate documents but rather as an interchange format for systems and devices to share documents. In the same way KIF is meant to facilitate sharing of knowledge across different systems that use different languages, formalisms, platforms, etc.

KIF has a declarative semantics. It is meant to describe facts about the world rather than processes or procedures. Knowledge can be described as objects, functions, relations, and rules. It is a formal language, i.e., it can express arbitrary statements in first order logic and can support reasoners that can prove the consistency of a set of KIF statements. KIF also supports non-monotonic reasoning. KIF was created by Michael Genesereth, Richard Fikes and others participating in the DARPA knowledge Sharing Effort.[1]
