There are a lot of links to books…
… but little links from books
How about linking content from a bookto your and other locations?
On the menu:
Digital publications…EPUB 3
... reconnecting them to the Web …NER, Semantic Web
… using their spatial information …DBPedia [lat,long]
… and the cool results!
EPUB 3: the Web in a box!°2011

Digital publications could befirst-class, interlinked Web-citizens…
But aren’t.
What can we do?
Reconnect all the boxes!
DBPedia spotlightRetrieve Semantic data
about digital publications
(Approximate) locationUse this Semantic data
to connection publicationswith locations

Done?
Done?Well… “almost”.
Not all (DBPedia) locationshave a geolocation…
What can we do?
Approximate the location of entitiesusing the location of relevant concepts

Averaging relevant concepts

Averaging gives pretty good predictions…and standard deviation gives good spread
Where is Mozart located?
Result: a contextualized reading experience
To take away
By augmenting EPUBs with their DBPedia-links…
and connecting these links with their spatial coordinates
… You reconnect digital publications with the Web …
… And create contextualized information for readers!
