Nouns in the Conceptual Framework "Node of Knowledge"

The "Node of Knowledge" method is one of the elements of the conceptual framework "Node of Knowledge (NOK)". It enables knowledge representation in graphical and formalized (textual) form and makes it possible to store formalized records of natural language sentences in a relational database. To enable correct transformation of all words from natural language sentences to formalized records, it is necessary to design a metamodel of a language, i.e. to analyse all word types of each particular natural language and define rules for transformation of sentences in natural language into formalized records. This paper analyses nouns in Croatian and English language. It presents rules for transformation of nouns and noun phrase structures into formalized records, with examples in both languages. The system is preliminary tested with a small set of sentences (used as input knowledge) and questions. Testing results are presented and discussed
