COMPUTER AND ECONOMIC MODELS OF NEW KNOWLEDGE GENERATION: A COMPARATIVE ANALYSIS
Two models of generating new knowledge are compared. The first, the spiral model, describes the processes of generating new knowledge in the economic sphere. The second model is used in computational linguistics and medical informatics. This model focuses on the design of information technologies and automated systems that ensure the generation of new knowledge during the semantic analysis of texts (referred to as the information technology-oriented model, or ITO model). The comparison of the two models is presented as a step- by-step transformation of the spiral model into the ITO model. The primary purpose of the paper is to describe four stages of transformation. At the first stage, mental and informational media are separated in the spiral model. Then, at the second stage, a digital medium is added to them with potential sources of new knowledge in the form of a database of text data corresponding to the goal of knowledge discovery from texts. The reference sample of the novelty of the discovered knowledge is being set. At the third stage, a list of eight processes of generating new knowledge is formed. A knowledge base is being added for storing forms of representation of concepts of newly discovered knowledge. The transformation of the spiral model into the ITO model is completed at the fourth stage by integrating eight processes of generating new knowledge. The stages of transformation are illustrated by an example of discovering new knowledge about the meanings of German modal verbs.
