Domain knowledge
Encyclopedia
Domain knowledge is that valid knowledge
used to refer to an area of human endeavour, an autonomous computer activity, or other specialized discipline.
Specialists and experts use and develop their own domain knowledge. If the concept domain knowledge or domain expert is used, we emphasize a specific domain which is an object of the discourse/interest/problem.
, domain knowledge is knowledge about the environment in which the target system operates, for example, software agent
s. Domain knowledge is important, because it usually must be learned from software users in the domain (as domain specialists/experts), rather than from software developers. Expert’s domain knowledge (frequently informal and ill structured) is transformed in computer programs and active data, for example in a set of rules in knowledge bases, by knowledge engineers.
Communicating between end-users and software developers is often difficult. They must find a common language to communicate in. Developing enough shared vocabulary to communicate can often take a while.
The same knowledge can be included in different domain knowledge.
Knowledge which may be efficient in every domain is called domain-independent knowledge, for example logic
s and mathematics.
Operations on domain knowledge are performed by meta-knowledge.

Knowledge is a familiarity with someone or something unknown, which can include information, facts, descriptions, or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject...

Software agent
In computer science, a software agent is a piece of software that acts for a user or other program in a relationship of agency, which derives from the Latin agere : an agreement to act on one's behalf...

Logic
In philosophy, Logic is the formal systematic study of the principles of valid inference and correct reasoning. Logic is used in most intellectual activities, but is studied primarily in the disciplines of philosophy, mathematics, semantics, and computer science...

It is a key concept in systematic software reuse. A key idea in systematic software reuse is the application domain, a software area that contains...
