Semantic analysis stages
Data is analysed by identifying the characteristic features of the given data set,
which then determine the decision. This decision is the result of the completed da-
ta analysis (Fig. 2.14).

Data analysis process
The data analysis process is complemented 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 ex-
pectations as to the analysed data generated using the expert knowledge base kept
in the system. The comparison leads to cognitive resonance aimed at identifying
consistent pairs and non-consistent pairs, where the latter are immaterial in the
further analysis. In cognitive analysis, the consistent pairs are used to understand
the meaning (semantics) of the analysed data sets (Fig. 2.15).
