GVSM

Sinopsis

Generalized Vector Space Model (GVSM).

Description

Usage

The best way to start is of course copying the Makefile in your working directory.

init

index

matrics

svd

lsi

eval Wrappers are in moscow:/usr9/xliu/gvsm.
If you want to see the source code for LSI and GVSM, they are at moscow:/usr3/xliu/work/lsi.

Example

Repeating part of Xin's work on the UNICEF corpus is a good example.
His documentation is complete and I'll review just a small part of it.
Goal: estimate the 11-avgp on the monolingual and translingual data sets of the UNICEF corpus.

Copy the Makefile in your gvsm directory .

Try "make init". It should create a source directory with a bunch of data files. Modify the SV value and "make all" will generate the corresponding evaluation files (look in the eval directory). For the UNICEF corpus, using ntc weighting.

Example
	500
MIR 11-avgp	0.3791
TIR 11-avgp	0.3674

DON'T FORGET TO CLEAN AND TIDY ('gmake clean tidy') AS SOON AS YOU GET THE DESIRED RESULTS. DATA AND TEMPORARY FILES USE LOTS OF RESOURCES.
