The mining methods are classified as the methods of data analysis and
the knowledge acquisition and they are derived from the methods of
"Knowledge Discovery". Within the scope of these methods, there are two
main variants associated with a form of data,
i.e.: "data" and
"text mining". The author of the paper tries to find an answer to
a question about helpfulness and usefulness of these methods for the
purpose of knowledge acquisition in the construction industry. The very
process of knowledge acquisition is essential in terms of the systems
and tools operating based on knowledge. Nowadays, they are the basis for
the tools which support the decision-making processes. The paper
presents three cases studies. The mining methods have been applied to
practical problems – the selection of an adhesive mortar coupled with
alternative solutions, analysis of residential real estate locations
under construction by a developer company as well as support of
technical management of a building facility with a large floor area.
