> Have a naive bayes classifier which uses plain BM25 scores instead of plain
> frequencies

> Project: Lucene - Core
> Issue Type: Improvement
> Components: modules/classification
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
> Fix For: master (7.0)
>
>
> {{SimpleNaiveBayesClassifier}} users term frequencies with add one smoothing
> to calculate likelihood and just tf for prior. Given Lucene has switched to
> BM25 it would be better to have a different impl which uses BM25
> scoring as a probability measure of both prior and likelihood.
