PersianLG

By Jon Dehdari, Brigham Young University Linguistics Department, 2003-2007

This README is for 'persianlg', a Persian (Farsi) implementation of the Link Grammar (LG) syntactic
parser.  The LG Parser is a new approach to parsing sentences, and was developed at Carnegie Melon
University.  The parser works by simply linking words together.  Directionality and distance are the
constraints given, and are found in the 4.0.dict file.


ABOUT PERSIANLG:

The Persian PersianLG implementation works a little differently than the English version, due to the
more complex word structure.  Morphological pre-parsing is required, either by using Perstem or the 
Persian-pckimmo morphology engine.  The LG-Soar framework, developed in the BYU Soar research group, 
has tied both the LG parser and the PC-Kimmo engine together, to provide seamless integration of 
morphology and syntax.  Thus manual morphology pre-parsing is not necessary, nor is cutting and 
pasting pckimmo output to the lgparser input.

For example, an unvoweled text like 'mn midAnm kh tu mi-rui.' (I know that you are going), should go
into the LG parser as 'mn mi dAn m kh tu mi ru i.'   See the orthography.txt file for the romanization
scheme used.


USAGE:

PersianLG may be used from the command line or from a web server.  A simple sentence may be parsed by
running the command:
echo 'dust-hAi mn ktAb rA didnd' | ./persianlg.sh
which will result in output like:
[...]
    +----------------------------Wi----------------------------+
    |        +-----------------------Spln----------------------+
    |        +-----EZm----+           +-----On-----+----VMP----+
    |        +-NMSp-+     +--M-+      +--PA--+     +-VMT+      |
    |        |      |     |    |      |      |     |    |      |
