1.1.1.4.2 The Knowledge Meta Process<br />

The Knowledge Meta Process consists of five main steps. Each step requires a decision to be<br />

taken at its end <strong>and</strong> results in a specific outcome. The most important aspects of the process are:<br />

• The main process indicates phases finally leading to an ontology based KM application: feasibility<br />

study, kickoff, refinement, evaluation <strong>and</strong> application & evolution.<br />

• Below each phase, its most important sub-steps are listed, e.g. kickoff comprises the sub-steps<br />

capture requirements <strong>and</strong> analyze sources (not integrated here).<br />

• Above each phase, the document flag indicates major outcomes of the step, e.g. results of the<br />

refinement in the target ontology.<br />

• The nodes on top of the flags represent the major decisions to be taken at the end of the phase<br />

in order to proceed. The outcomes serve as decision support.<br />

• The cyclic flashes connecting the phases refinement, evaluation <strong>and</strong> application & evolution indicate<br />

that these phases may need to be performed in iterative cycles.<br />

The feasibility study is the starting point of the Knowledge Meta Process. It helps to identify related<br />

stakeholders which are split into users <strong>and</strong> supporters of the system, as well as to use cases<br />

describing <strong>and</strong>/ or supporting the usage scenarios. If the feasibility study results in a ‘Go’<br />

decision, the results of the modeling serve as an input for kickoff (Studer et al., 2001; Sure, Staab<br />

& Studer, 2004; Sure, 2005).<br />

The actual development of the ontology begins with the kickoff phase. Similar to software<br />

engineering <strong>and</strong> as proposed by (Fernández-López et al., 1999) an ontology requirements specification<br />

document (ORSD) is the result of the first step. The ORSD should guide an ontology engineer in<br />

his development work. The requirements specification encompasses domain <strong>and</strong> objective of the<br />

ontology, design guidelines, knowledge sources (especially reusable ontologies <strong>and</strong> domain<br />

experts), (potential) users <strong>and</strong> usage scenarios, competency questions, <strong>and</strong> supported<br />

applications.
