käänatäpsusega

Käänatäpsusega is an Estonian term used in linguistics and natural language processing to describe the accuracy with which inflectional morphology is applied in text. The word is a compound formed from käänata (to inflect), täpsus (accuracy), and the instrumental suffix -ga, meaning “with” or “along with.” In practice, käänatäpsusega refers to how correctly a system handles inflection across case, number, possessive endings, and other grammatical markers in context.

In linguistic research, käänatäpsusega serves as a descriptor for how precisely a resource or model implements Estonian morphology. It is applicable to human- or machine-generated data, including corpora annotations, grammar checkers, morphological analyzers, and machine translation outputs. The concept is often used as a measurement criterion alongside other syntactic or semantic accuracy indicators.

Measurement typically involves comparing produced inflected forms against a gold standard or manually annotated reference. Metrics may be reported as overall inflection accuracy, per-category accuracy (such as case or possessive suffixes), and error analysis that categorizes frequent failure modes (for example, mismatched cases, incorrect possessives, or improper noun class agreement).

Challenges in assessing käänatäpsusega include the richness and irregularities of Estonian inflection, productive compounding, adopted vocabulary, and context-dependent choices. Differences in domain, register, and dialect can also affect inflection behavior, making consistent evaluation a nuanced task.

Related concepts include morphological tagging, lemmatization, and evaluation metrics for natural language processing.
