TNT Parser: Performance (4/4)

• More detailed information on filtering

  • CFG filtering
    • The time for filtering occupies 3.0% of total parsing time.
  • CFG filtering with vector unification
    • The time for filtering occupies 62.0% of total parsing time.

• This result suggests that drastic performance improvement may not be achieved by optimizing unification.

  • Pruning?　(POS taggers or other statistical metods)
  • Smarter filtering techinique?
  • Modifying grammars? (see SLUNG)
