Modelling domain knowledge using explicit conceptualization

Applications are characterized by the tasks and domains involved. Knowledge modeling can be divided into two conceptual subactivities: modeling the task and modeling the domain knowledge. An explicit conceptualization of the domain knowledge at the heart of its organization is discussed. A conceptualization is the objects presumed to exist and the relationships and functions among them. The annotations and the conceptualization guide the construction of applications and support flexible reasoning during problem solving. It also lets domain knowledge be reused
