Conceptual system
Encyclopedia
A conceptual system is a system that is composed of non-physical
object
s, i.e. ideas or concepts. In this context a system
is taken to mean "an interrelated, interworking set of objects".
. There are no limitations on this kind of model whatsoever except those of human imagination
. If there is an experimentally verified correspondence between a conceptual system and a physical system
then that conceptual system models the physical system. "values, ideas, and beliefs that make up every persons view of the world": that is a model of the world; a conceptual system that is a model of a physical system (the world). The person who has that model is a physical system.
In psychology
and social work
, when they talk about a conceptual system, they are referring to some person's model of the world, but if they try to understand that model, they end up making a model of that model, which is just a model of the person's behavior. In any case, this is exactly the purpose of the general term "conceptual systems".
idea
or a mental symbol, typically associated with a corresponding representation in and language
or symbology
, that denotes all of the objects in a given category
or class
of entities, interaction
s, phenomena, or relationships between them. Concepts are abstract in that they omit the difference
s of the things in their extension
, treating them as if they were identical. They are universal in that they apply equally to every thing in their extension. Concepts are also the basic elements of proposition
s, much the same way a word
is the basic semantic
element of a sentence
. Unlike perception
s, which are particular images of individual objects, concepts cannot be visualized. Because they are not, themselves, individual perceptions, concepts are discursive and result from reason
. They can only be thought about, or designated, by means of a name
. Words are not concepts. Words are signs for concepts.
s, relation
s, tables, stochastic process
es, formulas, axiom systems, rules of inference etc. A conceptual model has an ontology
, that is the set of expressions in the model which are intended to denote some aspect of the modeled object. Here we are deliberately vague as to how expressions are constructed in a model and particularly what the logical structure of formulas in a model actually is. In fact, we have made no assumption that models are encoded in any formal logical system at all, although we briefly address this issue below. Moreover, the definition given here is oblivious about whether two expressions really should denote the same thing. Note that this notion of ontology is different from (and weaker than) ontology as is sometimes understood in philosophy; in our sense there is no claim that the expressions actually denote anything which exists physically or spatio-temporally (to use W. Quine's formulation).
For example, a stochastic model of stock prices includes in its ontology a sample space, random variables, the mean and variance of stock prices, various regression coefficients etc. Models of quantum mechanics
in which pure states are represented as unit vectors in a Hilbert space include in their ontologies observable
s, dynamics
, measurement
operators etc. It is possible that observables and states of quantum mechanics are as physically real as the electrons they model, but by adopting this purely formal notion of ontology we avoid altogether this question.
project. The framework is built from a set of concept
s linked to a planned or existing system
of methods, behavior
s, functions, relationships, and object
s. A conceptual framework might, in computing terms, be thought of as a relational model
.
For example a conceptual framework of accounting "seeks to identify the nature, subject, purpose and broad content of general-purpose financial reporting and the qualitative characteristics that financial information should possess".
Physical system

Overview
A conceptual system is simply a conceptual modelConceptual model
In the most general sense, a model is anything used in any way to represent anything else. Some models are physical objects, for instance, a toy model which may be assembled, and may even be made to work like the object it represents. They are used to help us know and understand the subject matter...
