Abstract

Knowledge is the most precious asset of humankind. People extract the experience from the data that provide for us the reality through the feelings. Generally speaking, it is possible to see the analogy of knowledge elaboration between humankind's way and the artificial system's way. Digital data are the "feelings" of an artificial system, and it needs to invent a method of extraction of knowledge from the Universe of data. The cognitive computing paradigm implies that a system should be able to extract the knowledge from raw data without any human-made algorithm. The first step of the paradigm is analysis of raw data streams through the discovery of repeatable patterns of data. The knowledge of relationships among the patterns provides a way to see the structures and to generalize the concepts with the goal to synthesize new statements. The cognitive computing paradigm is capable of mimicking the human's ability to generalize the notions. It is possible to say that the generalization step provides the basis for discovering the abstract notions, revealing the abstract relations of patterns and general rules of structure synthesis. If anyone continues the process of structure generalization, then it is possible to build the multi-level hierarchy of abstract notions. Moreover, discovering the generalized classes of notions is the first step towards a paradigm of artificial analytical thinking. The most critical possible responsibility of cognitive computing could be the classification of data and recognition of input data stream's states. The synthesis of new statements creates the foundation for the foreseeing the possible data states and elaboration of knowledge about new data classes by employing synthesis and checking the hypothesis.
