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 (generalization) process in the mind. Conceptual models represent human intentions or semantics . Conceptualization from observation of physical existence and conceptual modeling are the necessary means that humans employ to think and solve problems . Concepts are used to convey semantics during natural language based communication . Since a concept might map to multiple semantics by itself, an explicit formalization is usually required for identifying and locating the intended semantic from several candidates to avoid misunderstandings and confusions in conceptual models.
