Detailed Description

Compute and store the LSA Index.

This class is used to compute the Latent Semantic Analysis (PLSA) values from the document index, and then store the values in a compressed index. This class makes use of the FloatIndex base class.

Note:

Requires the use of arpack++ to compute the SVD.
