Tommaso Teofili updated SOLR-2129:
----------------------------------
Attachment: SOLR-2129-version-5.patch
Changes are:
# drop StringBuffer for StringBuilder in UIMAUpdateRequestProcessor
# make the getAE method in OverridingParamAEProvider synchronized to support
concurrent requests to the provider
# make the getAEProvider method in AEProviderFactory synchronized and make the
cache "core aware", each core has now an AEProvider for each analysis engine's
path
# the UIMAUpdateRequestProcessor constructor accepts SolrCore as a parameter
instead of a SolrConfig object
I tested it with multiple cores and concurrent updates for each core.
> Provide a Solr module for dynamic metadata extraction/indexing with Apache
> UIMA

> 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.
