Abstract Models and algorithms of information retrieval in the global and local computer networks on the basis of thematic and dynamic text corpora are proposed in this article. The developed algorithms provide the effectiveness of documents information retrieval and notable for universality, i. e., for the independence from topics. Information system adjustment to a particular data domain can be fully automated, it adds up to the creation of a respective thematic text corpus and an actualization of dictionaries of the knowledge database.

Although use statistics are often used in the assessment of library collections and services, they are of limited value in evaluating the library’s effectiveness as an information system. This essay highlights three concepts from the information retrieval literature—recall, precision, and relevance—and describes a standard of relevance that accounts for the learning goals of the academic community as well as the performance goals of students. It also demonstrates how the academic mission of the university can be incorporated into the assessment and management of the library as an information retrieval system. The discussion concludes with guidelines for the assessment of recall and precision as well as suggestions for the integration of these concepts into library collection development, cataloging/access, reference, and instruction.

The information system “Scientific Heritage of Russia” has been created in stages since 2007. Currently, the existing software does not meet the needs of the system and complicates its further development. It was decided to implement the new version of the software in the asp.net core crossplatform environment. The article describes the decisions made in the implementation of software and modernization of the data structure. Particular attention is paid to the development of information retrieval tools.
