An important aspect of knowledge acquisition is the use of knowledge modelling as a way of structuring projects, acquiring and validating knowledge and storing knowledge for future use.
Knowledge models are structured representations of knowledge using symbols to represent pieces of knowledge and relationships between them. Knowledge models include:
- Symbolic character-based languages, such as logic
- Diagrammatic representations, such as networks and ladders
- Tabular representations, such as matrices
- Structured text, such as hypertext.
Uses of Knowledge Models
The generation and modification of a knowledge model is an essential aspect of knowledge acquisition, as the model helps to clarify the language being used and quickly convey information for validation and modification where necessary. Thus, the use of knowledge models is of great benefit during:
- knowledge elicitation (from an expert)
- validation (with the same expert)
- cross-validation (with another expert)
- knowledge publication
- maintenance and updating of the knowledge system or publication
Most forms of knowledge models are composed of primitive elements called knowledge objects.
