The authors propose a synthetic method for the extraction of contextual knowledge as an integrated approach that focuses on the problem of explication of context knowledge in Russian texts of Humanities and social orientation and subsequent typology of contextual knowledge in individual disciplines and interdisciplinary relations, as well as on General scientific and General cultural term-concepts, combining different disciplines. The problem has scientific and cultural significance, as contextual knowledge is an important part of the explicit and implicit knowledge that a person operates in the scientific, educational and cultural activities. The proposed approach to solving the problem of the explication of contextual knowledge is empowering technology thematizing flexible full-text and multi-modal search, implemented and tested in the framework of the virtual resource and service center, established in 2014-2016 on the basis of the ITMO University in the framework of the project RFH № 14-03-12017 (project "Humanitariana").
