Inference Engine
The processing portion of an expert system. With information from the knowledge-base, the inference engine provides the reasoning ability that derive inferences (conclusions) on which the expert system acts.
Inference Engine
The part of an expert system responsible for drawing new conclusions from the current data and rules.
The Inference Engine and the Rule Base:
The rule base is in fact a big database of rules, each in the form of: IF x1 is A1 and x2 is A2 and … And xn is An THEN y1 is B1 and y2 is B2 and… yn is Bn.
(Equation 1.5) ...
Inference engine
The 'reasoning' part of a computer program which interprets knowledge and data to determine logical conclusions.
Integrated Care Pathways ...
The inference engine that deals with reasoning is a completely separate module from the knowledge base and allows the easy modification and addition of rules that are immediately implemented through an English like language.
[edit] Shells or Inference Engine
A shell is a complete development environment for building and maintaining knowledge-based applications.
[86] However, a naive implementation of the algorithm quickly leads to a combinatorial explosion or an infinite loop, so sophisticated search methods are used to implement the inference engine that is at the core of a logical agent or logic ...
An expert system consists of a knowledge base, database and an inference engine for interpreting the database using the knowledge supplied in the knowledge base. The reasoning process of a typical illustrative expert system is described in Fig.
Typically, an expert system consists of two parts, an inference engine and a knowledge base. The inference engine is generic. It handles the user interface, external files, program access, and scheduling.
An expert system is comprised of a knowledge base and an inference engine. The knowledge base contains the accumulated knowledge of specialists in a narrowly defined area.
There are various expert systems in which a "rulebase" and an "inference engine" cooperate to simulate the reasoning process that a human expert pursues in analyzing a problem and arriving at a conclusion.
The second part of an expert system, the inference engine, is a logic program that interprets the instructions and evaluates the facts to make a decision.
In the last article, we left off with the inference engine producing fuzzy output response magnitudes for each of the effective rules. These must be processed and combined in some manner to produce a single, crisp (defuzzified) output.

s-expression a symbolic expression in Lisp, consisting of a symbol or a list structure whose components are s-expressions.
SAT Boolean satisifiability.
An expert system has a knowledge base (composed of rules describing the domain) and an inference engine integrating a set of reasoning mechanisms.
A common class of AI computer system that applies the logic and domain knowledge it has acquired from a human 'expert'. A typical expert system has three main parts - a knowledge base (that contains the rules), an inference engine (that interprets ...
about given facts) for which the processing sequences are not defined by the engineer. In short, the statements provide information regarding the association between several objects, or entities, and the system decides, through its inference engine, ...
