AAAI: Dude, Where’s My Service?

GogloAs the number of bioinformatics services on the web increases, finding a tool or database that performs the task you require can be problematic. At the AAAI poster session on Wednesday, I presented our paper describing a novel solution to this problem. It uses a reasoner to “intelligently” search for web services, by semantically matching service requests with advertisements and has some advantages over comparable solutions…

I won’t go into all the gory details here but our technique extends and complements current approaches for matchmaking services. Some of the key features described in the paper are that it allows you describe to relationship(s) between the input and output of a service. E.g. What is the relationship between the input and output protein sequence of InterProScan? This relationship can help match requests for services with their adverts with higher precision and recall. I don’t mind admitting its been hard work getting this research published because a large part of the AI community use shamelessly toy and fictitious scenarios to motivate their work. Then they build incredibly complicated software stacks that are only understood by the small clique of people that designed them. When you show some of these people real-world bioinformatics services, they don’t seem to care too much, preferring to bury their heads in the sand of make-believe. There, thats got it off my chest!

So it was re-assuring when people came by the poster, listened to my speel and asked lots of questions. Ora Lassila from Nokia (one of the people responsible for hyping the whole idea up in the first place) dropped by to have a look. He was interested in adapting the technique for locating services in a registry, used by mobile devices. (I wonder if anyone out there needs BLAST on their mobile phone?!) It was good to meet Ora, and talk about semantics.

There is nothing quite like standing in front of a poster for three hours and tirelessly explaining it to complete strangers who work in disparate fields. It certainly helps to get your ideas straight. Where would we be without conferences?
