Evaluation of thematic structure of multidisciplinary documents and document flows

The classification of documents of complex interdisciplinary character with a high level of informational noise is considered. The set of classification domains is supposed to be fixed; a domain is defined by a keyword list. The thematic structure of individual documents and document flow are discussed. The technology was implemented in a system document recognizer that solves the following tasks: evaluation of contribution of each domain to a document; distribution of document flow by the domains; and selection of a possible leader (most representative document) in each group.
