Hi Arthi, Antonio is completely right.
The original idea of the 'fise:selection-context' property was to give EnhancementEntinge the ability to specify the part of the text they used as context for the annotation. The EntityTaggignEngine does this by setting the selection-context to the three sentences used as context for the OpenNLP NER module. Engines that do not use such a context (e.g. write an Annotation only because of the 'fise:selected-text' would not need to add any 'fise:selection-context'. However users have started to relay on the selection-context to also (1) find mentions in rich-text documents (where the fise:start/fise:end positions do not apply) and (2) UI level elements (e.g. a tool-tip for users showing the context when hovering over a suggested tag). For (1) we have recently introduced the "TextAnnotation new model" (STANBOL-????). This adds prefix/suffix to the fise:selected-text. having those information makes it much easier as to re-find the exact location by using the fise:selection-context together with the fise:selected-text. For (2) we do currently not have a good solution. An additional engine that uses detected sentences or paragraphs (multiple line breaks without any non-whitespace char in-between) would be a great addition to Stanbol. Such an engine could provide configuration options that allow users more control over the context included in enhancements. For clearly supporting (2) I would suggest to add a new property 'fise:extraction-context' to be used by EnhancementEngines to specify the part of the content used to create the annotation and repurpose the current 'fise:selection-context' to be used for (2) best Rupert On Wed, Sep 25, 2013 at 3:24 PM, Antonio Perez <ape...@zaizi.com> wrote: > Hi Arthi > > I think it is not possible to achieve what you want using the configuration > of the NLP engines through Stanbol web console config. > > The only way of change a property (selection-context) of Text Annotations > is to implement a custom enhancement engine in order to can access to the > whole content being enhanced and modify the selection-context property of > each Text Annotation using the current selection-context and the whole > content (to get a line or paragraph for example). > > Regards > > > On Wed, Sep 25, 2013 at 1:38 PM, <arthi.ven...@wipro.com> wrote: > >> Hi, >> >> How can we change the default selection-context in the text annotation >> while using the enhancer.
