Hello,
I would like to display the context in which a term appears in some text, in the same way that Google shows the 5 or so words before and after your search term in the document.
Example -------
For this input:
<s id="39"> The aforementioned oxygenated <z:e sem="chebi" ids="33284">nutrient</z:e> emulsion (using the fluorocarbon FC-80) was placed in a Harvey pediatric oxygenator (volume 1230cc) and maintained at about 40 DEG C </s>
I want to show the 5 words before and after "nutrient":
... The aforementioned oxygenated *nutrient* emulsion (using the fluorocarbon FC-80) ...
Any ideas?
Thanks,
Antony
