=====
Code for grounded SMT on geoquery data or Free917 data.
(N.b. This has nothing to do with the programming language REBOL [0]!)
Dependencies
------------
###Geoquery:
_WASP_-1.0 includes the geoquery knowledge base and scripts for querying it.
The evaluation scripts were slightly modified to produce full outputs.
These scripts can be found in data/geoquery/wasp/, and they go into wasp-1.0/data/geo-funql/eval/.
WASP-1.0 can be downloaded from here [1].
You'll also need a _Prolog_ environment for geoquery, e.g. SWI-Prolog [2].
We use the a slightly modified implementation of _smt-semparse_,
as described in *Semantic parsing as machine translation* (Andreas et al, ACL 2013).
Our fork can be found here [3]. This software depends on more stuff, e.g. the Moses decoder
and SRILM.
###Free917:
The parser used for Free917 is _sempre_,
as described in *Semantic Parsing on Freebase from Question-Answer Pairs* (Berant et al, EMNLP 2013).
It can be downloaded here [4] and further dependencies can be found in QUICKSTART.md.
###Both:
For translation we use the _cdec_ toolkit, [5].
As semantic parsing is quite slow and rebol does it quite often,
results are cached with _memcached_ [6].
You'll need the following _ruby gems_:
* https://rubygems.org/gems/memcached
* http://rubygems.org/gems/zipf
* http://trollop.rubyforge.org/
