[jira] [Commented] (LUCENE-7116) Document Classifiers to handle
numeric fields
[ https://issues.apache.org/jira/browse/LUCENE-7116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15201712#comment-15201712 ]
Alessandro Benedetti commented on LUCENE-7116:
----------------------------------------------
relates to past classification issues
> Document Classifiers to handle numeric fields
> ---------------------------------------------
>
> Key: LUCENE-7116
> URL: https://issues.apache.org/jira/browse/LUCENE-7116
> Project: Lucene - Core
> Issue Type: Improvement
> Components: modules/classification
> Affects Versions: 5.5
> Reporter: Alessandro Benedetti
> Priority: Minor
> Labels: classification, classifier
>
> DocumentClassifiers should handle numeric fields.
> Knn Document Classifier should be able to handle function queries( like the distance from the numeric value in input) as boost factors on top of the MLT boolean query.
> Investigations will follow with tentative design and patch
> e.g.
> input document has price:5
> We can classify the document based on all the ones in the index, close to 5 as the price value.
