The data is structured and
generally located in databases
The information is implicit in
the input –data i.e. unknown
and not possible to extract
without automatic techniques
Patterns are extracted from
unstructured data in documents and
text files
the information is clearly stated in the
input text but it not implied in a manner
that is open to automatic processing.
Text Mining strives to bring out the
text in a form that is suitable for
computer processing directly without
human intervention
