Social, mobile, semantic
Monday’s DBpedia mobile presentation at LDOW2008 impressed me a lot. Actually, while I never worked on it, I’m really interested in ways to combine mobile applications, Semantic Web / Linked Data technologies and social networking. Here’s a use case I have in mind for a long time and I’d like to share.
Imagine in can embed a FOAF profile on my mobile phone, or just an URI with owl:sameAs / rdfs:seeAlso links to my main URI / RDF file. When joining a conference, a restaurant or any place where there are some people (and when I’m in a good mood), I allow my phone to deliver my presence and this URI (+ related data) to anyone, while at the same time searching for available URIs and data.
Then, I got a list of URIs, and my phone will suggest me that there’s some people nearby that I must meet regarding some criterias and how our URIs are interlinked. A simple way would be to configure the application with kind of (statement, depth) tuples. For example (foaf:interest, 2) would suggest me all people where one of my foaf:interest is link to one of their foaf:interest with a maximum path of 2. And of course, those paths should be computed using Linked Data and considering the whole SW graph, or GGG, e.g. going through DBpedia, GeoNames of any dataset from the LOD cloud if needed.
But, in some case, paths are not enough, as they can result to unrelevant results (depending on the start URI the path may quickly go towards too generic URIs), or sometimes too much people. For example, at a SW event, I guess it would have suggest me to meet anything since I have dbpedia:Semantic_Web in my profile. A solution could be to have an intelligent context manager in the mobile phone that will check my iCal, find that I’m attending a workshop (or even better, use GPS location, browse upcoming.org or other services to find which event I’m attending), retrieve the workshop homepage in which organizers embedded some RDF data about topics of the workshops (as they eat their own dogfood :), and exclude those URIs (and paths that goes through). To be more accurate, instead of those path tuples, I could also define complex queries, as for example: “People that will present some paper at a conference I’ll attend next month”.
Actually, it’s just a matter of providing all the data, open it, and of course, interlink. But well, “Linked Data is the Semantic Web done as it should be. It is the Web done as it should be“, no ?

Attending WWW2008
I’m currently in Beijing, enjoying WWW2008.
Sunday, Uldis, John and myself gave a tutorial about “Interlinking Online Communities and Enriching Social Software with the Semantic Web“, in which we detailed current state of the art regarding SIOC and related works, like how Enterprise 2.0 or data portability can be enhanced thanks to the Semantic Web, as well as describing various tools that produce or consume Social Semantic Web data. The slides can be browsed online here.
Today, I gave two talks at the LDOW workshop, the first one about the flickrdf exporter, the second one about MOAT, while Uldis talked about SIOC and Linked Data. Slides of both of my presentations are online. It was a great workshop, lots of interesting papers and concrete applications demo. That’s really interesting and encouraging to see so much people deploying Semantic Web technologies in various contexts and for various purposes, from biology to enterprise data integration, and also facing new research issues as URI identification and mappings.
Tomorrow starts the main conference, and I guess - and I hope - that it will be as intense and interesting as those first two days. For those interested in MOAT, I’ll give a talk in the Dev Track - Semantic Web II session on friday morning. And for those who’ve been at the LDOW workshop today, the slides will be a bit different, so you can come one more time
