CorpusAnalysen

CorpusAnalysen refers to the systematic study of linguistic corpora to investigate language use, structure, and variation. The field combines quantitative measurement with qualitative interpretation and can involve written and spoken corpora, or parallel corpora used for translation studies. It aims to describe actual language use rather than prescriptive norms and often compares genres, registers, or languages.

Methodologically, corpus analyses rely on corpus creation and annotation, including tokenization, lemmatization, part-of-speech tagging, parsing, and semantic tagging. Researchers use frequency analysis, collocations, concordances, distributional semantics, and, increasingly, machine learning. Common tools include AntConc, NLTK, SpaCy, Sketch Engine, and various database platforms.

Data sources include historical and contemporary texts, spoken data, web corpora, and domain-specific collections. Parallel corpora support translation studies; balanced corpora aim for genre and time representativeness.

Applications of corpus analyses span lexicography and dictionary compilation, language teaching, sociolinguistics, natural language processing model development, information retrieval, and forensic linguistics. Findings inform theories of lexical semantics, syntax, and pragmatics and support evaluation tools for language technologies.

Challenges include representativeness and sampling bias, annotation quality and interoperability across tools, handling multilingual data, and addressing privacy and copyright constraints in corpora containing personal material.

Historically, corpus analysis grew from mid-20th century computational linguistics with the advent of machine-readable corpora and has advanced through the development of large-scale resources and standardized annotation schemes, enabling cross-linguistic and cross-domain studies.
