Apertium Python Wrapper
Takes an Apertium language pair, a source-language sentence S, and a target-language sentence T, and outputs the set of all possible pairs of subsegments (s,t) such that s is a subsegment of S, t a subsegment of T and t is the Apertium translation of s or vice-versa (a subsegment is a sequence of whole words).
See http://wiki.apertium.org/wiki/User:Pankajksharma/Application#Proposal for more detail.
On the fly patching (repair.py)
usage: repair.py [-h] [-d D] [--min-fms MIN_FMS] [--min-len MIN_LEN]
[--max-len MAX_LEN]
S T S1 LP
On the fly repairing of sentence.
positional arguments:
S Second Sentence
T First Sentence Translation
S1 Second Sentence
LP Language Pair
optional arguments:
-h, --help show this help message and exit
-d D Specify the lanuguage-pair installation directory
--min-fms MIN_FMS Minimum value of fuzzy match score of S and S1.
--min-len MIN_LEN Minimum length of sub-segment allowed.
--max-len MAX_LEN Maximum length of sub-segment allowed.
fms.py
usage: fms.py [-h] S S1
Provides FMS of strings S and S1 using Wagner-Fischer algorithm.
positional arguments:
S First Sentence
S1 Second Sentence
optional arguments:
-h, --help show this help message and exit
reg_test.py
Regression test for our patcher
usage: reg_test.py [-h] [-d D] [-v] [--mode MODE] [--min-fms MIN_FMS]
[--min-len MIN_LEN] [--max-len MAX_LEN]
out LP
positional arguments:
out Output file generated from preprocess.py (en-es.pairs and en-es.pairs.s are included)
LP Language Pair (sl-tl)
optional arguments:
-h, --help show this help message and exit
-d D Specify the lanuguage-pair installation directory
