2.7. SUMMARY 29<br />
• Creation or import. The contents need to be created or converted so that they<br />
fit the conventions <strong>of</strong> the company.<br />
• Capture. Knowledge items have to be captured in order to determine their importance<br />
and how they mesh with the company’s vocabulary conventions.<br />
• Retrieval and access. This step satisfies the searches and queries <strong>for</strong> knowledge<br />
by the knowledge worker.<br />
• Use. The knowledge worker will not only recall knowledge items, but will process<br />
them <strong>for</strong> further use.<br />
The steps are illustrated in Figure 2.6. In this thesis, the scope <strong>of</strong> the knowledge<br />
management is only limited on type level process knowledge – enterprise/business process<br />
models. There<strong>for</strong>e, in the context <strong>of</strong> our process knowledge management, process<br />
modeling in knowledge representation language is concerned as knowledge creation.<br />
Importing knowledge can be the trans<strong>for</strong>mation <strong>of</strong> conventional process models in the<br />
knowledge representations. Knowledge capture is to capture the essential contents in<br />
process models through annotation techniques by creating metadata con<strong>for</strong>ming to<br />
ontologies. <strong>Process</strong> knowledge retrieval and access can be conducted through a conventional<br />
query or search tools, or by applying the ontology and the inference mechanism<br />
to derive further views <strong>of</strong> process knowledge. The possible uses <strong>of</strong> process knowledge<br />
include analysis <strong>of</strong> existing process models, reusing the legacy models to create new<br />
process models, integrating systems based on the process descriptions, etc.<br />
2.7 Summary<br />
This chapter has outlined the context <strong>of</strong> this research work. We have introduced the<br />
theoretical and technical setting relevant to our research topic, such as modeling theories<br />
and methodologies, the <strong>Semantic</strong> Web, ontology, semantic annotation, business<br />
process model and knowledge management. Main points are summarized as follows.<br />
• From the discussion <strong>of</strong> modeling theory and methodology, we has scoped that our<br />
research area is at conceptual modeling level.<br />
• Ontology as the key enabling technology <strong>for</strong> the <strong>Semantic</strong> Web provides an explicit<br />
representation <strong>of</strong> a shared conceptualization.<br />
• Ontology and conceptual model share certain common grounds, which indicates<br />
the potential links between them, e.g. usage combination and technology benefits<br />
from each other.<br />
• In this work, a concept modeling language – RML is used to analyze meta-models<br />
and ontologies with graphical notations; while, an ontology modeling language –<br />
OWL is applied to enable ontology machine-interpretable.<br />
• <strong>Semantic</strong> annotation is an approach to achieve semantic interoperability <strong>of</strong> heterogeneous<br />
in<strong>for</strong>mation resources making use <strong>of</strong> ontology.
