Fig. 2 Process of data analysis
The data analysis process is supplemented with the cognitive analysis, which
consists in selecting consistent pairs and non-consistent pairs of elements from the
generated set of features characteristic for the analysed set and from the set of
expectations as to the analysed data generated using the expert knowledge base
kept in the system. The comparison leads to cognitive resonance, which identifies
consistent pairs and non-consistent pairs, where the latter not material in the
further analysis process. In cognitive analysis, the consistent pairs are used to
understand the meaning (semantics) of the analysed data sets (Fig. 3).
