incomparably faster than a machine can. However, machine understanding techniques
are also improving, so in time they will be able to execute more complex reasoning by
referring to the meaning of the collected data, and not just executer simple analyses of
this data. Advanced artificial intelligence techniques are used to make information
systems capable of such semantic reasoning about data. Apart from the simple analy-
sis of information and the possible classification (recognition) of data identified for
analysing, these techniques also enable extracting significant semantic information
from this data, which indicates the interpretation of its meaning. At the present stage,
the semantic analysis of data is always rooted in some context assumed up front, as
the computer cannot at the same time discover the purpose of the analysis and its
result. This means that the cognitive systems being constructed are trying to under-
stand data and reason about it having the purpose of this reasoning specified. This
must be contrasted with a human, who encounters a specific novel situation, analyses
its many facets, and as a result can draw completely unexpected conclusions which
bear witness to the deep mental exploration of this situation, in other words to under-
standing it fully.
