A methodology of organizing the search for scientific and technical information and the creation of an appropriate information retrieval system is considered. The methodological basis is the three-level hierarchical structure of ontologies. The first level forms the conceptual apparatus of the subject area, the second level details the terminology of a specific area of scientific knowledge. Ontologies of the third level are focused on a specific scientific direction, they allow one to structure objects and research methods, as well as the scientific result and practical value of a scientific publication. An object data model is used. The basics of the language of information queries are proposed.

考虑了一种组织科学技术信息搜索和创建适当的信息检索系统的方法。方法论的基础是本体的三级层次结构。第一级构成主题领域的概念性设备，第二级详细描述特定科学知识领域的术语。第三层次的本体论集中在一个特定的科学方向上，它们允许人们构造对象和研究方法，以及科学成果和科学出版物的实用价值。使用对象数据模型。提出了信息查询语言的基础。
