> Key: STANBOL-1089
> URL: https://issues.apache.org/jira/browse/STANBOL-1089
> Project: Stanbol
> Issue Type: New Feature
> Components: Enhancement Engines
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
>
> With the Topic Classification Engine now supporting to configure different
> SolrCore configurations we should provide a configuration that does use
> n-grams for topic classification.
> While this will not scale for very big classification schemes is should
> provide improvements to small and medium sized models.
> Indexing of n-grams will be based on the Solr ShingleFilterFactory [1].
> The SolrCore configuration will be provided by the name
> 'shingle-topic-model.solrindex.zip' by the Topic ClassificationEngine bundle
> to the DataFileProvider. This means that users will need to configure this
> name with the 'org.apache.stanbol.enhancer.engine.topic.solrCoreConfig' of
> the TopicClassificationEngine. This property was added by STANBOL-1087
> [1]
