A unique method
Knowledge modelling or knowledge mapping is a formal or semi-formal method of seizing knowledge held by experts.
By bringing together the benefits of linguistics, artificial intelligence, cognitive sciences and logic, Onomia offers an innovative method for knowledge mapping:
- The experts are at the core of the approach
- The conceptualizations produced are consensual while supporting several points of view: different fields and different workplace communities
- The method is supported by knowledge mapping tools ensuring all that is required for capitalization and development
Implementing the method
Onomia’s method of ontoterminology building puts the emphasis on the conceptualization of the field and the role of the experts. It is also based on the fact that there is a difference between this conceptualization and the scientific and technical discussion it could give rise to.
The method has 5 stages and relies on Onomia’s tools for the management and building of ontoterminology:
1- Constructing a unified conceptual network: the aim is to build an initial conceptualization of the field, with the help of experts and existing mapping. This phase is independent of any specific representation languages (OWL, RDF, KIF) and is based on epistemological principles. Based on the 3 language levels: Natural Language, Intellection Language and Representation Languages.
2- Defining the formal ontology: a formal ontology is extracted from the conceptual network based on epistemological principles and relying mainly on definition through specific differentiation. The goal is to obtain a consensual, coherent and shareable ontology.
3- Extracting potential terms: if an ontology cannot be extracted from the texts (the lexical structure does not overlap with the field’s conceptual structure), text mining is a source of much linguistic information concerning the terms in use.
4- Selecting terms: the experts identify the terms in use and the standardized terms, proposing new terms (neologisms) where necessary.
5- Defining the ontoterminology: the final phase links concepts and terms (standardized and in use) by differentiating formal definitions from concepts from linguistic explanations from terms. The ontoterminology is exported following various formats: RDF, OWL, SKOS, etc.
Note: During the implementation of the method, tasks are cyclical and interconnected and the method proceeds in a more iterative manner.
