Tekstrelevans
Tekstrelevans is a measure of how relevant a text is to a given query or information need. In information retrieval, tekstrelevans describes the degree to which document content addresses the user's intent. Relevance depends on topical alignment, specificity, and usefulness, and can be evaluated with user feedback or relevance judgments.
Common approaches quantify tekstrelevans with lexical and semantic signals. Lexical methods include bag-of-words representations and scoring
A typical retrieval pipeline includes preprocessing of text, building an inverted index for fast lexical matching,
Evaluation of tekstrelevans relies on labeled relevance judgments and metrics such as precision, recall, mean average
Challenges include handling ambiguity, synonymy, negation, and polysemy; domain-specific language; noisy queries; and multilingual or cross-lingual
