FIELD: information technology.
SUBSTANCE: result is achieved by using a method of positioning text in knowledge space. In the disclosed method, elements are selected from input data, which correspond to patterns included in taxa which form taxonomia merged into ontology. Significant taxa are determined, which are weighed based on conditions assigned to patterns. A set of weighed vectors which position the input document in the knowledge space is constructed. An ontology set is used for positioning. When constructing sets of vectors, only those elements which correspond to patterns included in one taxon or in taxa having common parent taxa are considered.
EFFECT: high efficiency of search engines, contextual advertisement systems and systems for behavioural targeting on the Internet.
