Corpora @ SketchEngine.eu
The SketchEngine is a commercial corpus interface which was primarily developed with the needs of lexicographers in mind. What's unique about SE is that it features some (sadly rather opaque) algorithms for investigating how words are used in context. The functions are similar to the collocations function in CQPweb, but more intuitive. You can use SE to access a wide range of corpora (including the BNC and parallel corpora such as OPUS). EU-wide access is financed via the ELEXIS project until April 2022.
