The program to do logic extraction. Written in python and simply running it with one perl script. This program is the implementation of the following paper:

http://www.cs.utexas.edu/~ml/papers/wasp-logic-acl-07.pdf

This software was built upon Python 2.7.3. Using the same version of python (or higher) is recommended for best compatibility.

This software uses additional alignment software https://github.com/neubig/pialign to do word alignment. You need to install it first so it can be referenced from letrac.

You can download the data that is used for this software by clicking this link:

ftp://ftp.cs.utexas.edu/pub/mooney/nl-ilp-data/geosystem/geoqueries880

There is also smaller version of the data (only 250 lines):

To run the program, simply run the run-extraction.pl with some necessary options. Given now you are in your working directory, the sample of running the extraction is:

[LETRAC_DIR]/run-extraction.pl -pialign-dir [PIALIGN_DIR] -working-dir [OUTPUT_FOLDER] -input [GEOQUERY_INPUT] -letrac-dir [LETRAC_DIR]
