-__Showing the Occurrences within the Text__
+### Visualise Occurrences of extracted features
-This described how to obtain the necessary information needed to visualize
extracted Entities within the text.
+The occurrence of extracted features are represented by instances of the
concept 'fise:TextAnnotation'. However not all TextAnnotations are of interest
for this use case as they are also used for other things (e.g. annotating the
language of the parsed content).
+
+Typically the following steps are required to correctly show extracted
features within the content.
1. Query for/iterate over 'fise:TextAnnotation's of the enhancement results.
* it is important to only use TextAnnotations that define a
'fise:selected-text' property. TextAnnotations that do not define this property
usually select whole sections or even the document as a whole. Those are not of
interest for this use case.
2. Determine the exact occurrence of the TextAnnoations
* in case of plain text content this can be easily done by using the
values of 'fise:start' and 'fise:end'
* in case the content includes additional markup the char indexes of
'fise:start'/'fise:end' will not match. In such cases the preferred way is to
first search the occurrence of'fise:selection-context' and thann the occurrence
of 'fise:selected-text' within.
-3. Retrieve suggested Entities for a given TextAnnotation. For that one needs
to search for "?suggestion dc:relation {text-annotation}" where
'{text-annotation}' refers to the URI of the current TextAnnotation.
- * Note that there will be TextAnnotations with no suggestions.
+3. Retrieve the suggestions ('fise:TextAnnoation' instances) for a given

+ * Not every TextAnnotation will have suggestions
+ * One and the same suggestion might be linked with several TextAnnotations.
The following SPARQL query could be used to select all the required
information. However the use of SPARQL is optional as the required information
can be also easily retrieved by other means (e.g. the filtered Iteratros as
typically provided by RDF frameworks).
