EcoLexicon: English corpus of the Environment domain

The EcoLexicon English Corpus (EEC) is a text corpus of contemporary environmental texts. It consists of 23.1 million words and was prepared by the LexiCon Research Group at the University of Granada for the purpose of the development of EcoLexicon, a terminological knowledge base on the environment. This corpus is available with POS tags, lemmas and lempos.

Word sketches

A word sketch is a tool enabling users to explore word’s grammatical and collocational behaviour. The EEC employs word sketches based on the Sketch Grammar for English developed by León Araúz, San Martín and Faber (2016).

Text types

Text types contain information about corpus texts, e.g. domain (zoology, ecology) or language variety (British English). Thanks to these parameters, users can narrow their search:

  • Domain: the EEC encompasses all the domains and subdomains of environmental studies (e.g. biology, meteorology, ecology, environmental engineering, environmental law, etc.).
  • User: the EEC includes texts for three different types of user (depending on their level of expertise): expert, semi-expert, general public.
  • Geographical variant: the EEC comprises American, British, and Euro English.
  • Genre: the EEC covers a wide variety of text genres: journal articles, books, websites, lexicographical material, etc.
  • Editor: the EEC distinguishes texts edited by scholars/researchers, businesses, government bodies, etc.
  • Year: the EEC includes texts from 1973 to 2016.
  • Country: the EEC texts are tagged according to the country of publication.

Part-of-speech tagset

The EcoLexicon were tagged by TreeTagger using the Penn TreeBank tagset with Sketch Engine modifications.
