conceptual model
A conceptual model is a model made of the composition of concepts, which are used to help people know, understand, or simulate a subject the model represents. Some models are physical objects; for example, a toy model which may be assembled, and may be made to work like the object it represents.
The term ''conceptual model'' may be used to refer to models which are formed after a conceptualization or generalization process. Conceptual models are often abstractions of things in the real world whether physical or social. Semantics studies are relevant to various stages of concept formation and use as Semantics is basically about concepts, the meaning that thinking beings give to various elements of their experience.
== Models of concepts and models that are conceptual ==
The term ''conceptual model'' is normal. It could mean "a model of concept" or it could mean "a model that is conceptual." A distinction can be made between ''what models are'' and ''what models are models of''. With the exception of iconic models, such as a scale model of Winchester Cathedral, most models are concepts. But they are, mostly, intended to be models of real world states of affairs. The value of a model is usually directly proportional to how well it corresponds to a past, present, future, actual or potential state of affairs. A model of a concept is quite different because in order to be a good model it need not have this real world correspondence.〔Gregory, Frank Hutson (1992) (Cause, Effect, Efficiency & Soft Systems Models ) Warwick Business School Research Paper No. 42 (ISSN 0265-5976) in January 1992. With revisions and additions it was published as Cause, Effect, Efficiency and Soft Systems Models in Journal of the Operational Research Society (1993) 44 (4), pp 149-168.〕 In artificial intelligence conceptual models and conceptual graphs are used for building expert systems and knowledge-based systems, here the analysts are concerned to represent expert opinion on what is true not their own ideas on what is true.
