A number of electronic documents grows much faster than a human is able to deal with. Though inormation retrieval methods help to identify documents likely containing a given information based on keywords, text mining approaches deal with the interpretation of information hidden in the documents. This difficult task is related to the semantics of a natural language that is difficult to interpret unequivocally even for trained experts. Text mining adopts various statistical and information retrieval methods, approaches of a computational linguistics and artificial intelligence classification methods. In text mining, following tasks are solved: Informatin extraction - the identification of key text components and of relationships between them, Topic tracking - an intelligent text filtering based on the user profile, Summarization - the summariozation of text content, Sentence extraction - the identification of sentences that are important for text understanding, Categorization, classification, clustering - text categorization based on content similarity, Concept linkage - the identification of relationships between texts with common concepts.
