WikiMwe is a large resource of English multiword expressions mined from Wikipedia. It contains over 350,000 multiword units of size 2-4, including

  • technical terminology,
  • non-compositional multiword expressions, and
  • collocations.

For each entry, POS and frequency information and pointwise mutual information (PMI) scores are included. Additionally, we provide definitional and category information for many entries, to facilitate the application of the resource in theoretical (semantic similarity, domain disambiguation) and applied (terminology extraction) NLP research.

Coming Soon

We are currently working on WikiMwe resources for other languages (starting with German) and on the development of a software package for the language-independent extraction of multiword expressions from Wikipedia. We will make these resources available in the future.

Please contact me if you have any questions regarding the resource: Silvana Hartmann.
