This folder contains some scripts to execute the system. They all need
to be edited slightly before use with proper paths to corpora and/or
models. They are meant to be executed from the parent directory, e.g.
cd $DIST_ROOT
sh scripts/learn.sh
There are some comments in the script on switches etc. The amount of
memory used is typically whats required for the English CoNLL 2009
corpora. It might be possible to push it down a bit.
Since the system grew out of the CoNLL 2009 ST, there are a couple of
different ways to parse a corpus:
(i) parse_full.sh - parses a complete corpus using all steps of the
pipeline except tokenization. It pretty much
assumes that that the file contains tokens in the
second column and disregards the rest.
If the -nopi switch is used, it needs to have the
IsPred column from the CoNLL 2009 data format.
(ii) parse_srl_only.sh - parses semantic roles only. The input is
expected to be the CoNLL 2009 data format
with proper dependency trees (ie. the
SRLonly evaluation corpus).
In order to replicate the setting of the 2009
ST, one can use the -nopi switch to skip the
predicate identification step.
Then there is also the HTTP interface. This is started by the
run_http_server.sh script. Again, edit the file with proper paths
before executing it.
NOTE: the http server depends on the java package
com.sun.net.httpserver (cf.
http://download.oracle.com/javase/6/docs/jre/api/net/httpserver
/spec/com/sun/net/httpserver/package-summary.html
and
http://blogs.sun.com/michaelmcm/entry/http_server_api_in_java
), which is not part of the real Java specification, but comes with
most (or at least some) JRE distributions. From my own experience,
it is included in the Sun Java 6 distribution* as well as the OpenJDK
Java 6**.

The graphical dependency graph output of the HTTP interface relies on
having Chinese fonts install properly locally. On Linux I had some issues
with this, but resolved them according to
http://blog.lizhao.net/2007/03/java-chinese-fonts-on-ubuntu.html
The graphcical dependency graph output also seems to work less good
when using OpenJDK. The images get strange lines through them. The Sun
JRE seems to work fine though.
