> 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
