CHEU-lex is a parallel and comparable corpus of Swiss and European Union (EU) legislation published in the three official languages of the Swiss Confederation (French, German and Italian). It comprises: 1) bilateral agreements entered between Switzerland and the EU from 1972 to 2017; and 2) Swiss federal legislation representing the reception of these agreements. The corpus aims at providing a richly annotated multilingual resource to investigate the influence of EU drafting and translation practices on Swiss legislation. Its development is led by Prof. Annarita FELICI as part of a project funded by a grant of the Ernest Boninchi Foundation.

Owing to its structure, CHEU-lex datasets can be explored from a monolingual (e.g. bilateral agreements in a single language), parallel (e.g. bilateral agreements in the three languages), cross-textual (e.g. bilateral agreements and Swiss legislation in the same language), intratextual (e.g. by text subsections) or diachronic perspective to obtain information on frequency, concordance, parts-of-speech (POS) or syntactic features.
