==== Description: ====
                    
                        GPoSTTL 

(Brill's Parts-of-Speech Tagger, with built-in Tokenizer and Lemmatizer)

GPoSTTL is an enhanced version of Brill's rule-based Parts-of-Speech Tagger
for English, with built-in Tokenizer and Lemmatizer. It reads from FILE or
STDIN and writes to STDOUT. It is based on LPost package by Jimmy Lin
(jimmylin at umd.edu). LPost itself is based on Benjamin Han's ePost package,
which is a cleaned-up version of Eric Brill's original code. The primary lemma
list was taken from e_lemma.txt (Ver.1), complied by Prof. Yasumasa Someya
(someya at someya-net.com), with permission. Later it has been and being
enhanced by hundreds of additional entries. 

Motivations:

    * GPoSTTL has been developed as a free software alternative for
TreeTagger [1], a non-free Penn Treebank tagger developed by Prof. Helmut
Schmid. GPoSTTL can be used as a drop-in substitute for TreeTagger.

As an explicit case, GPoSTTL is used as a crucial component of Anubadok[2], a
GPL'ed machine translator for English to Bengali. 


The default mode of GPoSTTL uses enhanced Penn tagset to make its output
compatible with the output of TreeTagger. In particular, second letter of the
verb tags distinguishes between "be" verbs (B), "have" verbs (H) and other
verbs (V). The enhancement is done at last step of tagging procedure as its
lexicon contains the original Penn tagset.


GPoSTTL is written in C and the source code is available
from http://www.imsc.res.in/~golam/gposttl/

==== Other Software Required: ====
The program doesn't have any external dependency apart from
those available in a free operating system.


==== Other Comments: ====
The project is currently hosted in my personal webpage at IMSc[1].
Recently, I have left IMSc after completing my PhD. So the current
web space will expire withing few months.
