Hi Michel, Let me tell you about some generic use cases about usage of the ontology you pointed out.
1) You can create a referenced site from this ontology so that this referenced site can be used to extract entities during the enhancement process of a content item. To create a referenced site from the ontology you pointed, you can use the instructions that are explained in [1]. Also the documentation page for using custom vocabularies in Stanbol is at [2]. The mail thread at [3] includes valuable information about index creation and problems you can encounter. Let me propose a mappings configuration for the ontology you pointed out. Basically, the properties you specified in these configurations will be fetched from the ontology and indexed. You can directly write full URIs of the properties you want to index e.g: http://www.w3.org/2000/01/rdf-schema#label http://www.mindswap.org/2003/nciOncology.owl#id http://www.mindswap.org/2003/nciOncology.owl#code http://www.mindswap.org/2003/nciOncology.owl#Semantic_Type http://www.mindswap.org/2003/nciOncology.owl#Preferred_Name http://www.mindswap.org/2003/nciOncology.owl#UMLS_CUI http://www.mindswap.org/2003/nciOncology.owl#CTRM_ID http://www.mindswap.org/2003/nciOncology.owl#NSC_Code http://www.mindswap.org/2003/nciOncology.owl#Synonym 2) To be able to use the referenced site in the enhancement process, the easiest way from my side is to configure a "KeywordLinkingEngine". @Stanbolers, please correct me if I'm wrong. [2] contains documentation about the "KeywordLinkingEngine". 3) You can create semantic Solr indexes to store your documents together with their enhancements obtained via Stanbol Enhancer. This can be done thanks to LDPath[4] integration of Contenthub. You can use RESTful services of Contenthub to create new Solr cores based on the provided LDPath. See also the documentation at [5]. Here is a possible LDPath program that can be used to create semantic Solr indexes. @prefix rdfs : <http://www.w3.org/2000/01/rdf-schema#>; @prefix nci : <http://www.mindswap.org/2003/nciOncology.owl#>; nci_semantic_type = nci:Semantic_Type :: xsd:string; nci_umls_cui = nci:UMLS_CUI :: xsd:string; When you submit a document to the Solr core created based on this LDPath, all named entities detected from the document will be queried with this LDPath. This means, the fields of entities will be obtained from Entityhub and they will be stored along with the actual content. 4) You can use the semantic Solr indexes directly through their HTML entry points or you can use Contenthub with different kinds of search functionalities e.g. keyword search, faceted search. This is a long story and there is much to read. Please ask about any further questions if you have any.
