The paper presents an approach to extraction of facts from texts of documents. This approach is based
on using knowledge about the subject domain, specialized dictionary and the schemes of facts that describe fact
structures taking into consideration both semantic and syntactic compatibility of elements of facts. Actually
extracted facts combine into one structure the dictionary lexical objects found in the text and match them against
concepts of subject domain ontology.
