Abstract

The selection and representation of concepts in indexing of the same documents in 2 databases of library and information studies are considered. the authors compare the indexing of 49 documents in KINF and LISA. They focus on the types of concepts presented in indexing, the degree of concept consistency in indexing, and similarities and differences in the indexing of concepts. The largest group of indexed concepts in both databases was the category of entities while concepts belonging to the category of properties were almost missing in both databases. The second largest group of indexed concepts in KINF was the category of activities and in LISA the category of dimensions. Although the concept consistency between KINF and LISA remained rather low and was only 34%, there were approximately 2,2 concepts per document which were indexed from the same documents in both databses. These common concepts belonged mostly to the category of entities
