LocWeb2015 - Reconnecting Digital Publications to the Web Using their Spatial Information

Digital publications can be packaged, distributed, and viewed via the Open Web Platform using the EPUB 3 format. Meanwhile, the increased amount of mobile clients and the advent of HTML5’s Geolocation have opened a whole range of possibilities for digital publications to interact with their readers. However, EPUB 3 files often remain closed silos of information, no longer linked with the rest of the Web. In this paper, we propose a solution that addresses the difficulties of reconnecting digital publications with the Web using the spatial location of the concepts mentioned in the publication. We enrich digital publications by connecting the detected concepts to their URIs on, e.g., DBpedia, and use an algorithm that uses these URIs to retrieve or approximate the coordinates of these concepts. The evaluation of the approximation algorithm showed that almost any concept can be linked to a coordinate, but that the errors can be very high when context information is limited. This means relevant locations for a user can be shown, based on the content he or she is reading, and based on his or her location. This methodology can be used to reconnect digital publications with the online world, to entice readers, and ultimately, as a novel location-based recommendation technique.

- There are a lot of links to books…
- … but little links from books
- How about linking content from a book to 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
- EPUB 3: the Semantic Web in a box! °2014
- EPUB 3: the Semantic Web in a box! the Semantic Web Open, standardized formats HTML5, CCS3, JS Machine-understandable RDF(a) in a box Packaged zip
- Digital publications could be first-class, interlinked Web-citizens… But aren’t. What can we do?
- Reconnect all the boxes! DBPedia spotlight Retrieve Semantic data about digital publications (Approximate) location Use this Semantic data to connection publications with locations 1 2
- Done?
- Done? Well… “almost”.
- Not all (DBPedia) locations have a geolocation… What can we do?
- Approximate the location of entities using the location of relevant concepts
- Approximate the location of entities using the location of relevant concepts Relevant? Abstract Links Entities? Can be used for entities that aren’t actual locations!

- Averaging relevant concepts 100 km
- Averaging relevant concepts 1 km
- 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!
