The importance of contextual metadata (part 2)

Now as we advance in the techniques that may be used for discovering metadata, through better discovery, improvements have been made so that metadata may appear in a document in a contextual location.

For examply by using the structure of paragraph and metadata recognition routines it would be possible to do something like the following.

"John and Sara searched for kransky at their local supermarket in Sydney."
becomes
"<paragraph><sentence><name>John</name> and <name>Sara</name> searched for <food>kransky</food> at their local supermarket in <location>Sydney</location>.</sentence></paragraph>"

I've dumbed it down so that nothing conflicts. Now the information now has a context, so while it's still possible to drill down on name (it'd have to be extracted to seperate field like in the previous post). Now that the information is constructed in such a fashion it's now possible to search for a sentence or paragraph that contains a food and a person. Or for a sentence that contains a name John and a location. Of course the ability to search such marked up data relies on you having either a very good search engine at your disposal or the willingness to write one. ;-)
