Language is one of the universal cognitive tools of our mind, a communication tool reflecting our visible and inner life. The semantic aspect of a word – its real meaning – is becoming one of the most fascinating issues in contemporary computational linguistics and artificial intelligence science [1]. One of the most important fields in the area of artificial intelligence (AI) is knowledge representation (KR). Knowledge can be stored in different ways [2], [3], [4], for example by using: semantic networks [5], [6], frames [7] and ontologies [8]. The Node of knowledge method (NOK method), which belongs to a group of semantic networks, can be used for knowledge representation. The NOK method is a method for modelling nodes of knowledge and it is used to graphically express knowledge in a form of a diagram, called Diagram of Node of knowledge (DNOK). The method is based on research and analysis of natural human languages, which is important for approaching the topic of human intelligence. NOK method analyses sentences, words and their meaning, as well as the sequence of connecting words into more complex forms [9]. The entity-relationship method, as prescribed by MIRIS - Methodology for Information Systems Development [10], [11] presents a business organization, its parts, relationships between parts and part attributes. A database is a non-redundant set of data on all occurrences of entities, all relationships and all their attributes described in database scheme [10]. Since the database structure is described by the relational model, we analysed the art of transforming database knowledge into NOK model. In this paper we will show how to present database content and database structure using the NOK method. The relational model is based on the entity-relationship diagram (ER diagram). Tables are used for the presentation of database content.
