Subject [jira] [Commented] (SOLR-8542) Integrate Learning to Rank into Solr
Date Fri, 13 Jan 2017 10:36:27 GMT

Christine Poerschke commented on SOLR-8542:
-------------------------------------------

bq. How about "Learning To Rank" as a sub-page of the "Query Re-Ranking" ... +1 ... I like
that idea.

[Learning To Rank|https://cwiki.apache.org/confluence/display/solr/Learning+To+Rank] is now
the documentation page. I renamed and relocated the page and updated 'code' and 'ref guide'
references to it. http://git-wip-us.apache.org/repos/asf/lucene-solr/commit/987e2650 and http://git-wip-us.apache.org/repos/asf/lucene-solr/commit/9b03e384
are the 'code' commits.

bq. Regarding the alternative of "Machine Learned Ranking", how about reserving that for future
use ...

Tentative page name and draft content now at https://cwiki.apache.org/confluence/display/solr/Machine+Learning+and+Solr
because I think there's actually already enough functionality (Learning To Rank from SOLR-8542
here and [~joel.bernstein]'s Logistic Regression Text Classification) to bring the "future
use" into the present - what do you think?

> This is a ticket to integrate learning to rank machine learning models into Solr. Solr
Learning to Rank (LTR) provides a way for you to extract features directly inside Solr for
use in training a machine learned model. You can then deploy that model to Solr and use it
to rerank your top X search results. This concept was previously [presented by the authors
at Lucene/Solr Revolution 2015|http://www.slideshare.net/lucidworks/learning-to-rank-in-solr-presented-by-michael-nilsson-diego-ceccarelli-bloomberg-lp].
