model to design a lightweight ontology.

APPLICABILITY

The semantics of the relation between narrower and broader terms are subClassOf.

A thesaurus represents the knowledge of a domain with a collection of terms and a limited set of relations between them. The record-based data model is a denormalized structure, uses a record for every term with the information about the term, such as synonyms, broader, narrower and related terms.

2. For each one of the above identified thesaurus terms ti:

2.1. Create the corresponding ontology class, Ci class, if it is not created yet.

2.2. Identify the thesaurus term, tj , which are narrower terms of ti. They are referenced in the same record which contains ti.

2.3. For each one of the above identified thesaurus term tj :

2.3.1. Create the corresponding ontology class, Cj class, if it is not created yet.

2.3.2. Set up the subClassOf relation between Cj and Ci

2.3.3. Repeat from step 2.2 for cj as a new ci

2.4. Identify the thesaurus term, tr, which are related terms of ti. They are referenced in the same record which contains ti.

2.5. For each one of the above identified thesaurus term tr:

2.5.1. Create the corresponding ontology class, Cr class, if it is not created yet.

2.5.2. Set up the relatedClass relation between Cr and Ci

2.5.3. Repeat from step 2.4 for cr as a new ci

2.6. Identify the thesaurus term, tq, which are equivalent terms of ti. They are referenced in the same record which contains ti.

2.7. For each one of the above identified thesaurus term tq:

2.7.1. Apply the SynonymOrEquivalence (SOE) pattern.

2. Create the competence class and assert that competence is subClassOf learning.

3. Create the performance class and assert that performance is subClassOf development.

4. Assert that achievement is label of the performance class.

5. Assert that competence is relatedClass of performance.

6. Create the learning class and assert that learning is equivalentClass of competence.

6.1. Create the efficiency class and assert that efficiency is subClassOf performance.

6.2. Create the failure class and assert that failure is subClassOf performance.

6.3. Create the success class and assert that success is subClassOf performance.
