Description copied from class: SimilarityESA

Computes the vectors for the texts in the given set. If a previously computed object exists (and overrideObjects==False), it just loads the previously computed vectors.

Specified by:

computeVectors in class SimilarityESA

Parameters:

documentsPath - path to the documents

object - name of the (previously generated object)

set - whether we are processing A or B

Returns:

Throws:

java.lang.ClassNotFoundException

java.io.IOException
