----------------------------------------------------------------
NIST - TREC - Video Track - GS tasks partial Recall, precision@20 
and partial average precision calculation program
----------------------------------------------------------------

---------
0-Purpose
---------
This program is design to calculate some additional measures 
to the GS evaluated submission files.
The files are evaluated which means that they have the additional 
judgment and multishot Xml attributes. As a consequence this program
is only useful if you add 'evaluate' your system's output.
If you want to change the way the measure are calculated, please
download the sources.
If you want to get the same results has provided by NIST, please
find the archive submissions of all participating groups.

---------------------
1-System Requirements
---------------------
This small program requires :
	- JDK 1.1.8 or later (including any version of Java 2 : http://java.sun.com/j2se/1.3/)

--------------
2-Installation
--------------
1. Download the tar file
2. Untar the file

The content of tar file should be (all untar in a GSSoft folder) :

-Readme.txt, 
-GS_Prog.jar,
-SbRef directory with 2 DTD and 44 Xml files,
-GsResults directory with 2 DTD and 2 example of GS evaluated files,
-Output directory containing 2 directories RecallResults and RecallSet,
the first will contain the results of calculation of partial recall and other
measures and the second will contain the SB reference shots (one file by topic)
that matches with the original GS evaluated submission files.
-xerces-1_4_4 directory (Xml parser).

-------------
3. Running it
-------------
java -jar GS_Prog.jar

-The output will be in directories within Output directory.
