indekseerimisele

Indekseerimisele is a term used in Estonian information science to refer to the process of indexing—creating and applying index terms to documents to improve their discoverability. In library and information science, indexing involves analyzing a document’s content to identify its key concepts, topics, and entities, and then assigning descriptors such as subject headings and keywords that reflect those contents. The result is metadata that supports retrieval in catalogs, repositories, and search systems.

Indexing can be performed manually by trained indexers or automatically by software. Hybrid methods combine both approaches. The use of controlled vocabularies and thesauri helps standardize terms, reduces ambiguity, and enhances cross-language and cross-collection retrieval. Common metadata standards guide how indexing terms are stored, such as MARC, Dublin Core, and other bibliographic schemas, and facilitate interoperability between systems.

Indexing supports different retrieval modes: traditional subject-based search in catalogs, author and title indexing, and, in digital environments, full-text and semantic indexing. Full-text indexing allows keyword searches across the entire text, while semantic indexing aims to capture relationships between concepts and improve query expansion.

Challenges include language-specific terminology in Estonian, multilingual materials, evolving vocabularies, and maintaining consistency across large collections. The quality of indexing affects precision and recall in information retrieval, making ongoing training, quality control, and periodic reevaluation important.

Indekseerimisele remains central to libraries, archives, and digital repositories seeking to improve findability and user satisfaction.
