Современное состояние нормативной базы поискового индексирования информационных ресурсов издательств и библиотек

The author analyzes the key principles of developing search thesauri and indexing methods used in the library and publishing industry. The basic concepts of building information retrieval thesauri, specialized dictionaries used for indexing resources in dictionary information retrieval systems, are based on the use of metadata, search indexes, to determine the thematic relevance between indexed information resources and search queries. The author shows that in the field of information search in recent years, keyword search languages based on specialized dictionaries with controlled vocabulary, information retrieval thesauri, have become widespread. The author examines the main stages of the development of thesauri – from the construction of the structure of search terms and the concepts expressed by them, to the formation of a systematic structure of knowledge expressed by terms. The author discusses the reflection of the development of concepts for building information retrieval thesauri and search indexing in the regulatory knowledge organization framework adopted on the Internet and developed by the World Wide Web Consortium (W3C), as well as at the level of international (ISO) and Russian national (GOST) standardization organizations. The author concludes that it is necessary to update the Russian national regulatory framework for search indexing by harmonizing Russian and international standards in this area.
