Tekstikorpusten

Tekstikorpusten is a term used in Estonian-language corpus linguistics to describe a collective set of text corpora used for research and language technology. The concept emphasizes the aggregation of multiple corpora, spanning genres, domains, and languages, to enable large-scale linguistic analysis, comparative studies, and robust language models.

A typical tekstikorpusten includes newspaper, literary, and web-derived texts, as well as spoken or transcribed material and specialized domains (for example legal or technical texts). Each component is usually annotated to varying levels, such as tokenization, part-of-speech tagging, lemmas, and syntax, and is accompanied by metadata describing source, date, and license.

Researchers use tekstikorpusten to estimate word frequencies, study collocations, develop linguistic resources, improve machine translation, and train statistical or neural language models. When combining corpora, practitioners tackle issues of representativeness, domain bias, date range, and annotation interoperability.

Access is typically governed by research institutions and data licenses. Some components are publicly available, with standard formats (for example TEI-annotated XML or CoNLL-style tags) and documented metadata to facilitate interoperability.

The concept is closely related to corpus linguistics, language resources, and natural language processing. Ongoing efforts focus on expanding coverage, enhancing annotations, and ensuring ethical use, including privacy considerations and copyright compliance.
