The epistemology of the 20th century concentrated mostly on problems of knowledge justification, verification or falsification, putting aside the issues of knowledge creation, even if at the end of the 20th century a few works emerged stressing the necessity of understanding issues related with the creation of knowledge, see e.g. Searle (1992), Motycka (1998). This problem area became more actual and urgent because of the growing civilization change, a turn from the industrial civilization to a new society and civilization based on information and knowledge. Therefore, other disciplines than philosophy (knowledge management and systems science) developed so called micro-models of knowledge creation processes for the needs of today and tomorrow. This chapter presents a review of such models.
