One of the things I find annoying while attending conferences is the huge amount of papers we receive: Talks, maps, “metadata” about the conference in general. So, for ISWC2010, my solution was to create a mobile application where people attending a conference could retrieve the information they wanted.
The first question you may ask when you create a mobile app is which niche you want to cover: The mobile ecosystem contains a wide range of devices, each of them with different capabilities, features, etc. This implies that a developer should choose which platforms to support and which feature he or she can use.
With ISWC in mind, my impression was that most of the attendees would use a smartphone, in particular iPhones or Android. Since I wanted to cover both platforms, I decided not to create native applications (for now).
In this app it is possible to obtain and navigate through information about authors, papers, workshops (sadly, I could not obtain the data about workshop papers on time), scheduling, rooms and sessions. The data is obtained from a SPARQL endpoint containing the ISWC 2010 metadata. Each action implies a SPARQL query end the results are retrieved as a JSON object. I also obtained picture of authors from Arnetminer.
Finally I added a twitter feed with all the relevant hahstags (#iswc, #iswc2010, #cold2010, #seres2010, #c3lsw2010, etc.), so you can read what people is tweeting about the latest events (you shouldn’t have problems with firewalls, etc).
I encourage you to go to http://iswc.mobi and try ISWC Mobile. Of course, comments suggestions (and bug reports!) are always welcome.
