Processing and analysis of scientific bibliographic bilingual documents
In this paper we consider advantages and disadvantages of using bibliographic descriptions instead of the full texts for text categorization. We draw a conclusion that the most appropriate is to apply bibliographic descriptions for scientific documents analysis (papers, patents, reports on the conferences). We describe procedures for extracting informative terms and profile classification methods, form samples of the bilingual (Russian-English) scientific papers. We develop a new combined profile method, that reduces error (we measure it on examine samples). The weight of the terms in the combined profile is calculated on the basis of the normalized Chi-square criterion application, the normalized mutual information criterion and the Jaccard coefficient application. Also we analyze the directions of the further researches.
