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</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ядерные знания</kwd><kwd>управление ядерными знаниями</kwd><kwd>информационная система</kwd><kwd>свободное программное обеспечение</kwd><kwd>тезаурус</kwd><kwd>глоссарий</kwd><kwd>таксономия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nuclear knowledge</kwd><kwd>nuclear knowledge management</kwd><kwd>information system</kwd><kwd>free software</kwd><kwd>thesaurus</kwd><kwd>glossary</kwd><kwd>taxonomy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполняется в рамках мероприятия 13 «Выполнение работ по оказанию научно- технической поддержки Министерству по чрезвычайным ситуациям Республики Беларусь в области обеспечения ядерной и радиационной безопасности» подпрограммы 3 «Научное обеспечение эффектив- ной и безопасной работы Белорусской атомной электростанции и перспективных направлений развития атомной энергетики» Государственной программы «Наукоемкие технологии и техника» на 2021–2025 гг.</funding-statement><funding-statement xml:lang="en">The work is carried out within the framework of the activity 13 "Performing work to provide scientific and technical support to the Ministry of Emergency Situations of the Republic of Belarus in the field of ensuring nuclear and radiation safety" of Subprogram 3 "Scientific support for the effective and safe operation of the Belarusian nuclear power plant and promising directions for the development of nuclear energy" of the State Program "High-tech technologies and equipment" for 2021–2025</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Maintaining Knowledge, Training and Infrastructure for Research and Development in Nuclear Safety: INSAG-16. – Vienna : IAEA, 2003. – 19 p.</mixed-citation><mixed-citation xml:lang="en">Maintaining Knowledge, Training and Infrastructure for Research and Development in Nuclear Safety: INSAG-16.
