Korpusperusteinen

Korpusperusteinen is a Finnish adjective meaning "corpus-based" or "based on a corpus." It describes methods, analyses and resources that rely on linguistic corpora—large, structured collections of real-world texts or speech recordings—to inform research, description or practice. The term is used in linguistics, lexicography, language teaching, translation studies and natural language processing.

In a korpusperusteinen approach, empirical evidence from corpus data guides decisions about grammar descriptions, vocabulary lists, frequency analysis and usage patterns. This can involve quantitative techniques (frequency counts, n-gram analysis, collocation measures) and qualitative inspection of concordances and contextual examples. The approach contrasts with intuition-based methods that rely primarily on native-speaker judgments or prescriptive rules.

Applications include the compilation of dictionaries and phrasebooks, syllabus design for language courses, terminology extraction, corpus-informed machine learning models and discourse analysis. Benefits of korpusperusteinen work include grounding claims in authentic usage, uncovering variation and change, and supporting data-driven resource development. Limitations include corpus representativeness, annotation quality, and the need for appropriate tools and expertise to interpret statistical patterns responsibly.

Related concepts include korpusajattelu (corpus thinking), korpuslingvistiikka (corpus linguistics) and korpusperusteinen kieliteknologia (corpus-based language technology). As digital corpora and processing tools proliferate, korpusperusteinen approaches remain central to empirical language study and applied language work.
