Class RelatedKeywordProcessor

java.lang.Object
  com.raritantechnologies.concept.RelatedKeywordProcessor

All Implemented Interfaces:: IConfigurable, IGatewayOutputProcessor, IResultSetProcessor

public class RelatedKeywordProcessor
extends java.lang.Object
implements IGatewayOutputProcessor, IResultSetProcessor

Uses clustering to compute related keywords based on co-occurrence of keywords within IResult text fields. Uses a nested IDocumentKeywordProcessor to handle related keyword extraction. The related keywords can be determined by proximity within the document text, and a threshold of minimum number of associations can be set.

Creates an output IResultSet with one result per keyword from the input result sets. Each output result contains a nested result set with the set of related keywords as well as metrics on the strength of the association.

XML Configuration Template:

  <OutputProcessor class="com.raritantechnologies.concept.RelatedKeywordProcessor"
                      keywordField="[ result field that gets main keyword ]"
                      associatedKeywordsField="[ result field that gets list of associated keywords ]"
                      minAssociationDistance="[ minimum word distance for association ]"
                      minNumberAssociations="[ minimum number of associations needed ]" >

    <DocumentProcessor class="[ class of com.raritantechnologies.concept.IDocumentKeywordProcessor ]" >

    </DocumentProcessor>

    <!-- Gateway Output Processor to handle related document results -->
    <OutputProcessor class="[ class of com.raritantechnologies.searchApp.dataCollection.IGatewayOutputProcessor ]" >

    </OutputProcessor>

  </OutputProcessor>
