Indekseerija

Indekseerija is a person or software component responsible for creating indexes of documents to improve search and retrieval. In library science, indexing involves selecting representative terms, assigning them to documents, and organizing them in a way that supports finding information. In digital environments, indekseerija can refer to automated indexers that use natural language processing, statistical methods, and topic modeling to extract keywords and metadata.

Indexing typically includes choosing keywords, applying controlled vocabularies or classification schemes, tagging metadata elements such as subject, author, and date, and linking terms to the document content. The resulting index or metadata record enables search systems to match queries with relevant documents, often helping to handle synonyms and word variants.

Manual indexing relies on human expertise in a subject area; automatic indexing relies on algorithms. Many information systems use a combination of both to balance precision and recall, and to accommodate evolving terminology and new content.

Contexts and applications include libraries, archives, publishers, and digital repositories, as well as search engines and content management systems. Indekseerija workflows may involve quality control, consistency checks, and alignment with metadata standards and controlled vocabularies to ensure discoverability across collections and platforms.
