Hi, thanks for your answer.
I mean Topic Annotation.
Ultimately what i would like to have is something like: { PDFuri
FoaF:PrimaryTopic London . } as triple in the return RDF.
But for now, i don’t concern myself with using FOAF.
I just want to have the main topics of the PDF. I don’t necessarily want to
extract all the entity etc….
SO maybe in term of the annotation generated i would say not having
fise:EntityAnnotation neither fise:TextAnnotation but simply
fise:TopicAnnotation
Many thanks

What do you mean by "topic"? In case of PDF files the Tika Engine [1]
can extract metadata. Such metadata are directly added to the URI of
the contentItem and do not use FISE.

All Stanbol Engines do generate FISE enhancements
(fise:TextAnnotation, fise:EntityAnnotation and fise:TopicAnnotation)
When you look at the list of engines [2]
* Language Detection engines create a fise:TextAnnotation describing
the language of the document (?la dc:type dc:LinguisticSystem; ?la
dc:language ?lang)
* Named Entity Recognition (NER) Engines create fise:TextAnnotations
for Entities recognized by the NLP framework.
* Linking / Suggestions create fise:EntityAnnotation for Entities
found in the text. They might also add fise:TextAnnotation to mark the
exact mention of such entities in the text.
* Topic Classification engines use fise:TopicAnnotation to describe
assigned topics. They also use a fise:TextAnnotation to mark the part
of the text the topic is assigned to

Yep this page describes the annotations as created by the EnhancementEngines.
Without knowing what you mean by " ... only the topic of the pdf ..."
I can not recommend you suitable Stanbol configurations.
