Tommaso Teofili commented on SOLR-2129:
---------------------------------------
Hi Grant, I think it would be great to have Mahout classifiers inside Solr :)
I like your suggestion at point 1.
I can change the current hardcoded mapping mechanism using instead a simple
mapping between UIMA extracted types/features and field names defined inside
solrconfig.xml.
A different option could be to develop a SolrCASConsumer component in UIMA
(similar to Lucas [1], Lucene CAS Consumer) providing full control on how UIMA
annotations and features can be mapped to Solr fields, but on UIMA side ;)
Regarding point 2 the jars are already under contrib/uima/lib so I can modify
the sample solrconfig.xml adding the proper <lib> tag.
Thanks for your comments and suggestions.

> Provide components to enable Apache UIMA automatic metadata extraction to be
> exploited when indexing documents.
> The purpose of this is to get unstructured information "inside" a document
> and create structured metadata (as fields) to enrich each document.
> Basically this can be done with a custom UpdateRequestProcessor which
> triggers UIMA while indexing documents.
> The basic UIMA implementation of UpdateRequestProcessor extracts sentences
> (with a tokenizer and an hidden Markov model tagger), named entities,
> language, suggested category, keywords and concepts (exploiting external
> services from OpenCalais and AlchemyAPI). Such an implementation can be
> easily extended adding or selecting different UIMA analysis engines, both
> from UIMA repositories on the web or creating new ones from scratch.
