Constructor Detail

SimilarityESAdocs

public SimilarityESAdocs(java.io.File documentsApath,
                 java.io.File documentsBpath,
                 java.lang.String indexPath,
                 java.lang.String language,
                 boolean overrideObjects)

Includes the path to the documents in A and B. It is assumed that all the documents in the two paths should be considered for the similarities computations.

Parameters:

documentsApath - path to documents A

documentsBpath - path to documents B

indexPath - path to Lucene's index

language - language

overrideObjects - whether objects should be overridden

Method Detail

setDocumentsPath

protected void setDocumentsPath(java.io.File documentsApath,
                    java.io.File documentsBpath)

Description copied from class: SimilarityESA

A method that loads the texts in collections A and B.

Specified by:

setDocumentsPath in class SimilarityESA

computeVectors

protected EsaVectors computeVectors(java.io.File documentsPath,
                        java.lang.String object,
                        java.lang.String set)
                             throws java.lang.ClassNotFoundException,
                                    java.io.IOException

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.io.IOException

java.lang.ClassNotFoundException
