we're not going to do your work for you.
What have you done already, and what specifically do you have problems with?
It's your project, so you'd better start learning about what you're supposed to do.

hello, im not sure if i should post this here...
im trying to work with the GATE system, i want to perform the Named Entity Recognition task with ANNIE, an information extraction system that comes with GATE.
i want to call ANNIE in my code, so i have to use GATE Embedded.
and when i try to call the method Gate.init(), it gives me an exception:
this is the entire command line process, in windows:

C:\Documents and Settings\Administrator\Desktop\example>java StandAloneAnnie "target_text.txt"
Initialising GATE...
GATE home system property ("gate.home") not set.
Attempting to guess...
Using "C:\Program Files\GATE-5.1" as GATE Home.
If this is not correct please set it manually using the -Dgate.home option in your start-up script
Using C:\Program Files\GATE-5.1 as GATE home
Using C:\Program Files\GATE-5.1\plugins as installed plug-ins directory.
Using C:\Program Files\GATE-5.1\gate.xml as site configuration file.
