Knowledge modeling

<h2 id="explicitation-of-document-content">Explicitation of document content</h2>
Knowledge modeling includes the explicitation of knowledge and requirements that is available in documents, such as design manuals, (international) standard specifications and standard data sheets. 
In order to make such knowledge computer interpretable it needs to be expressed in a formal knowledge representation language and thus transformed into a computer interpretable form. 
For example, in the form of an expressions Gellish English. This enables that the knowledge and requirements are related to the objects in the knowledge model, whereas the whole model is again stored in a Database.The knowledge that is contained in documents can be modeled at various levels of explicitation. 
A low level of explicitation keeps large parts of the specifications in the form of natural language text. This means that the text is only human interpretable, but is nevertheless related to the objects in the knowledge model. 
Thus software can still present the information to users when knowledge about that object is requested. The other extreme is that the content of each sentence in a documents is converted in the formal knowledge representation language and thus the objects that are mentioned in those sentences become an integral part of the computer interpretable knowledge model. 
For example, the knowledge that the API 617 standard contains a standard specification for compressors can be linked to the concept compressor in the knowledge model of a compressor system. 
This can be expressed in a knowledge representation language (using the relation type ⟨is specified in⟩ as follows:

<ul><li>compressor ⟨is specified in⟩ API 617</li></ul>
A higher level of explicitation means that paragraphs or sentences in natural language are related to components in the knowledge model. A full explicit model means that the natural language sentences are completely transformed into data in a database structure.
For example, a specification of a minimum shaft diameter might be included in the knowledge model as follows:

<ul><li>shaft diameter 	⟨shall have on scale a value greater than⟩ 	20 	mm</li></ul>
The above described explicitation process results in Knowledge Models and Standard Specifications Models that enable their use for computer supported knowledge-aided design as well as for automated verification of designs.
