Sample text

There is a mapping between the proposed service ontology and the OWL-S definition. A service data can be mapped to the property of hasInput, hasOuput, hasLocal. A service operation can be mapped to the definition of an atomic process. The relationship between two operations can be defined by a composite process in an OWL-S ontology. Suppose that an airline service provides a flight ticket reservation functionality. It has the service data as follows: (I)={user information, departure date, arrival date, departure city, arrival city}.

3) It should be disciplined to ensure that sufficient information is provided. In this chapter, we present a formal language, the Service Change Management Language (SCML), to specify top-down changes. Since a change introduces new requirements on the LCS’s features, we first present a taxonomy that classifies top-down changes based on their requirements. The taxonomy is built on top of the proposed LCS schema. Based on the change taxonomy, we then present the SCML that enables the formal specification of changes.

Formal specification refers to the fact that knowledge should be specified in a machine-processible language. Explicit specification refers to the fact that concepts and their relationships should be defined explicitly. An ontology should avoid of containing implicit information to decrease confusion in knowledge specification. g. people, stuff, courses) in a given domain. These terms can be presented in an ontology in form of classes (concepts). The relationships between these terms can be shaped as a lattice or taxonomy of classes and subclasses.
