In addition, we need ways
to interpret ontology.

Semantics makes it easier to take advantage of a service that only partially
matches a request. (Lee et al. 2001, p. 37)
Given the importance of the Semantic Web components to achieve processes integration
and automation, we analyze in more detail relevant work in the areas of
ontologies, DLs, and intelligent agents in the next two subsections.
Ontologies and Description Logics
Ontologies provide a shared and common understanding of specific domains that
can be communicated between disparate application systems, and therein provide a
means to integrate the knowledge used by online processes employed by organizations
(Klein, Fensel, Van Harmelen, & Horrocks, 2001).
