Abstract: The invention belongs to the field of information system technology and more specifically in the area of electronic content management. The invention concerns method producing filtering systems of electronic documents that contain text in different languages, e.g. English, French, etc., as well as multimedia elements, e.g. digital images and/or digital video and/or digital excerpts of audio/speech. These documents can be semi-structured, i.e., they can exhibit structural features that are not to be found in non-digital documents, e.g. hyperlinks, or not. The method can be applied in the same way and provides the same results either to the filtering of electronic content in the Internet (World Wide Web, electronic mail, etc.) or in organizational computer networks (e.g. intranets), as well as in any other network that allows the transfer of multimedia and/or multilingual electronic content.
