Constructor Detail

SimilarityESAlines

public SimilarityESAlines(java.io.File docA,
                  java.io.File docB,
                  java.lang.String indexPath,
                  java.lang.String language,
                  java.lang.Boolean overrideObjects)

Given two files with independent sentences, process line-wise similarities.

Parameters:

docA - first text file

docB - second text file

indexPath - path to the Lucene index

overrideObjects - whether vector similarities should be computed from scratch

analyzer - the analyzer to consider (for various languages)

Method Detail

setDocumentsPath

protected void setDocumentsPath(java.io.File fileA,
                    java.io.File fileB)

Description copied from class: SimilarityESA

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

Specified by:

setDocumentsPath in class SimilarityESA

setObjects

protected void setObjects()

Description copied from class: SimilarityESA

Set the name of the resulting vector objects

Overrides:

setObjects in class SimilarityESA

computeVectors

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

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:

file - 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

processLine

protected java.lang.String processLine(java.lang.String text)

Method used to do some preprocessing to the input text. In this configuration nothing is done, but in others (e.g. in SimilarityESAsent.java), some modifications are carried out

Parameters:

text -

Returns:
