Tommaso Teofili commented on LUCENE-4345:
-----------------------------------------
bq. Can we remove the ClassificationException? It only seems to box
IOException... we can just throw IOException directly instead?
sure, we can keep IOException for now
bq. What is the scale that you expect this bayesian classifier to handle? How
many training documents does it need?
I'm doing some benchmarking in these days therefore I should be able to say
something about this shortly.

> Lucene/Solr can host huge sets of documents containing lots of information in
> fields so that these can be used as training examples (w/ features) in order
> to very quickly create classifiers algorithms to use on new documents and /
> or to provide an additional service.
> So the idea is to create a contrib module (called 'classification') to host a
> ClassificationComponent that will use already seen data (the indexed
> documents / fields) to classify new documents / text fragments.
> The first version will contain a (simplistic) Lucene based Naive Bayes
> classifier but more implementations should be added in the future.
