Basics of the semantic portal of nuclear knowledge BelNET functioning

Object ives. The possibility of using semantic technologies for the development and improvement of the content management system of the scientific and educational portal eLab-Science and the Belarusian nuclear knowledge portal BelNET (Belarusian Nuclear Education and Training Portal, https://belnet.by/) created on its basis is being considered.
Methods. Original algorithms for automatic systematization have been developed, such as placing content records in the portal taxonomy based on semantic technologies and generating a list of keywords. The following concepts of semantic technologies are used: taxonomy (hierarchical structure of the portal), thesaurus, glossary. Resul t s. The developed algorithms were implemented and tested using a full-text search tool and the original Belarusian glossary on nuclear and radiation safety.
Conclusion. The described basic principles of organization and algorithms based on semantic technologies, which underlie the functioning of the content management system of the scientific and educational portal eLab-Science and the Belarusian nuclear knowledge portal BelNET, created on its basis, make it possible to effectively implement the placement of content records in the portal taxonomy, as well as automatically generate a set of keywords for the resource being created
