How should I cite TCSE?

Please cite Hasebe (2015) and/or Hasebe (2018), and take the corpus size and version from the figures shown on the documentation home rather than from the published articles, which describe the system as it was at the time of writing. See How to Cite TCSE for the full references and guidance.
