Automated search for contradictions in concrete-historical information

The article continues the series of works devoted to the technology of concrete historical research support. The technology is based on the principles of co-creation and crowdsourcing and is designed for a wide range of users which are not professional historians and biographers. The article is devoted to the further development of the technology by integrating the mechanism of automated search for contradictions in concrete-historical information. The impossibility of using existing approaches to this problem was substantiated by the specificity of concrete-historical research and the processed in its context information which is presented in the form of historical-biographical fact. The goals of searching for contradictions in concrete-historical information which follow from this specificity and consist not in reducing of available to the researcher information but in discovery of new lines of research are formulated. The classification of types of contradictions in concrete-historical information is carried out and the usage of the mechanism of normals supporting regulating the dependencies between facts is justified. The necessary changes to the technology object model are described and justified, the algorithm is described in detail, and the procedures for processing search results are defined.
