- For our research, we are looking for a large grammar for natural language;
- this grammar should be a context-free grammar possibly extended with
- parameters and features of any form. The parameters and features are not
- important to us, nor is the language generated by the grammar or the
- declarative "meaning".
-
- Our purpose is to measure the size of different (variants of) LR parsers
- for natural language grammars. In particular, the influence of epsilon
- rules (which sometimes make normal LR parsers or Tomita parsers loop) on
- the size of LR tables is of great interest to us. The ``nastier'' the
- grammar is for computational reasons the better it is for us. (We would
- prefer a grammar which has been written without any regard for its
- computational properties.)
-
- We are looking for an appropriate grammar for a long time now. If you
- have one, then we would be extremely grateful if you would make it
- available to us. If you would like to ``encode'' the grammar first such
- that it can no longer be used for language recognition (e.g. by deleting
- the parameters/features or giving the nonterminals dummy names) then it
- would be fine with us.

- [I thought people gave up trying to parse natural language using LR methods
- in about 1966. Does anyone still use transformational grammars, a la COMIT?
