Task: Class Definition Understanding (ontology: Legal/LKIF_Core_Ontology)

Which of the following definitions best describes 'Document'?

A. A the concept bears some (and only) expression(s) stated by some statement in writing.
B. A the concept connects a person (the holder of the attitude) to some proposition, in fact it expresses some qualification over the proposition. Distinguishing a proposition from the propositional content expressed by it is necessary when properties relating to the thing expressed and properties of the expression itself must be distinguished. For LKIF the distinction between Belief, Intention, Qualification, and Observation is relevant. The distinction between belief/expectation, intention, and observation is relevant for i.a. establishing mens rea (guilty mind). The distinction between beliefs (expressing the content of the mind of an agent) and statements (expressing the content of an act of communication by an agent) is classical.
C. Metaphor of physical concepts, i.e. the things we mentally manipulate, either in thought or memory
D. We made the assumption that our views of the mental world have been developed in analogy with physical processes. Mental objects like thoughts are made of elementary parts: concepts. The contents (substance) of these objects are representations. The conceptual content of thoughts are intended by propositional attitudes, like belief, desire, norm etc. Mental objects are processed or stored in containers like a mind which has parts like various memories. Mental processes like thinking, memorizing, imaging, etc. are operations on mental objects. The energy equivalent of mental processing are emotions: the forces that make us focus our mental energies. 

There is an important difference between the mental world and the physical. Where physical processes occur causally, mental processes are controlled by an intentional stance. The outcome of mental processes can be the intention to act. The intention to act may consist of a structure of primary actions: a plan. The actions can be aimed at bringing about physical changes, but they may also be aimed at changing the mental state of another agent: these intended actions are communication actions. Like direct actions, communication actions have a physical appearance. They also need some physical medium to transfer the intended mental state. Speech act is the common term for these actions. 

Whether this notion of intended control over mental processes and actions is an illusion or not is besides the point in modeling common-sense. The intentional stance implies a kind of backward, teleological reasoning over causally related processes. A mental object like a  plan consists of a goal state (intention) and is produced by reasoning from goal to means (actions): this is what rational agency behavior is about. 

The mental world is not only a reflective one based in our minds eye. We may observe the stream of conscious mental processes, but the role of the mental conceptualizations is of even more important in understanding and communicating with other people. Mental processes and attitudes (sources of intention) are in the first place the building stones for modeling the minds of other people. The intentional stance means in the first place that we attribute to others and to some extent also to many animals intentions and intention directed mental processing and belief.

Answer: A the concept bears some (and only) expression(s) stated by some statement in writing.
