Nice to read that this is sufficient for your use case. I will still create a JIRA issue for an Engine that uses paragraphs and sentences to create more UI friendly fise:selection-context values. best Rupert > Thanking you and Regards, > Arthi > > > -----Original Message----- > From: Rupert Westenthaler [mailto:rupert.westentha...@gmail.com] > Sent: Thursday, September 26, 2013 11:04 AM > To: dev@stanbol.apache.org > Subject: Re: How to change the selection context retrieved in a Stanbol > enhancement. > > 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.
