ELS functionality in the field of information retrieval: results of comparative analysis

The results of the study “The potential of electronic library systems for a university of culture” are presented. The objects of the study are the electronic library systems “Urayt”, “Lan”, “Rukont”, “Universitetskaya biblioteka online”, “IPR Smart”. The analysis was carried out during the frontal training of first year students at the Moscow State Institute of Culture in information search algorithms in the ELS for typical information requests. The main drawback of ELS in the field of information search has been identified the presence of a significant proportion of irrelevant documents in search results. The low quality of local linguistic means (rubricators and classifiers) used in ELS has been established, as well as a violation of the logical requirements for the classification of objects. Recommendations for improving search tools in ELS based on the development of linguistic support tools and eliminating such shortcomings as: the presence of a large number of irrelevant publications in search results, the inoperability of advanced search fields, and the lack of necessary filters to cut off search noise are formulated.
