Rupert Westenthaler resolved STANBOL-500.
-----------------------------------------
Resolution: Fixed
Implemented with #1294113
> LDPath Repository wrapper over ContentItem
> ------------------------------------------
>
> Key: STANBOL-500
> URL: https://issues.apache.org/jira/browse/STANBOL-500
> Project: Stanbol
> Issue Type: New Feature
> Components: Content Hub, Enhancer
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
>
> This will allow to access the contents of a ContentItem by LDPath [1] and
> support
> * Access to the metadata
> * Access to the Content stored in Blobs via the fn:content(String mediaType)
> * Optional access to additional metadata stored in ContentParts with a type
> compatible to Clerezza TripleCollection
> * support for "shortcuts" to easily access "semantic concpets" defined by the
> enhancement structure including
> ### Used Namespaces:
> @prefix fise : <http://fise.iks-project.eu/ontology/> ;
> @prefix ci :
> <http://stanbol.apache.org/ontology/enhancer/content-item-ldpath-wrapper#> ;
> The "fise" namepsace represents the currently used Enhnacement Structure. The
> namespace "ci" does not correspond to any real ontology. It is only used
> internally by this LDPath wrapper for supported "shortcuts" as described
> below.
> ## Supported Functions and Shortcuts
> * Content support
> content = fn:content({content-resource},{media-type},{media-type2},..,
> {media-typeN})
> This returns the value of the first Blob matching any of the parsed media
> types. The value of {content-resource} must be the URI of the ContentItem OR
> the URI of a ContentPart compatible to the Blob interface.
> * extreacted TextAnnotations
> ci:textAnnotation = ^fise:extractedFrom[rdf:type is fise:TextAnnotation]
> * EntityAnnotations
> ci:entityAnnotation = ^fise:extractedFrom[rdf:type is
> fise:EntityAnnotation]
> * EntitySuggestions for TextAnnotations
> {text-annotation}/ci:suggestion = {text-annotation}/^dc:relation[rdf:type
> is fise:EntityAnnotation]/fn:sort(fise:confidence,"DESC")
> * Suggested Entities for a given {text-annotation}
> {text-annotation}/ci:suggestedEntity =
> {{text-annotation}/^dc:relation[rdf:type is
> fise:EntityAnnotation]}/fise:entity-reference
> * All extracted Entities
> ci:extractedEntities = ^fise:extractedFrom[rdf:type is
> fise:EntityAnnotation]/fise:entity-reference
> or if defined via the above 'ci:entityAnnotation' shorcut
>
> ci:extractedEntities = ci:entityAnnotation/fise:entity-reference
> Example of an envisioned LDPath program used to extract knowledge of a
> ContentItem as of LDPath Statements
> text = fn:content(.,"text/plain");
> personName = (ci:textAnnoation[dc:type is
> dbpedia:Person]/fise:selectedText) |
> (ci:textAnnoation[dc:type is
> dbpedia:Person]/ci:sugestion/fise:entity-label) :: xsd:string
> orgName = (ci:textAnnoation[dc:type is
> dbpedia:Organisation]/fise:selectedText) |
> (ci:textAnnoation[dc:type is
> dbpedia:Organisation]/ci:sugestion/fise:entity-label) :: xsd:string
> placeName = (ci:textAnnoation[dc:type is
> dbpedia:Place]/fise:selectedText) |
> (ci:textAnnoation[dc:type is
> dbpedia:Place]/ci:sugestion/fise:entity-label) :: xsd:string
> personRef = ci:entityAnntotation[fise:entity-type] is
> dbpedia:Person]/fise:entity-reference :: xsd:anyURI
> orgRef = ci:entityAnntotation[fise:entity-type] is
> dbpedia:Organisation]/fise:entity-reference :: xsd:anyURI
> placeRef = ci:entityAnntotation[fise:entity-type] is
> dbpedia:Place]/fise:entity-reference :: xsd:anyURI
> conceptRef = ci:entityAnntotation[fise:entity-type] is
> skos:Concpet]/fise:entity-reference :: xsd:anyURI
> NOTES:
> * The "shortcuts" as defined above could be also implemented as function
> such as
> fn:textAnnotation({content-item},[{dc-type}, {dc-type2},...{dc-typeN}])
> fn:suggestion({text-annotation},[{entity-type},
> {entity-type2},...{entity-typeN}])
> this would allow usages such as
> personName = (fn:textAnnoation(.,dbpedia:Person)/fise:selectedText) |
>
> (fn:textAnnoation[.,dbpedia:Person)/fn:suggestion(.)/fise:entity-label) ::
> xsd:string
