Libby Miller : WhoWhatWhenWhere
It's a simple bot based on the excellent PircBot api , which was really nice to use. It's essentially a text UI to a number of 'web services' which use urls - not SOAP in this case (but it could use SOAP; it is just easier this way).
You can ask it about wordnet (.wn fig), airport data (.airport bristol, .iata BRS), foaf knows (.knows libby miller), pictures (.pic Damian Steer), codepiction paths (.paths Dan Brickley, Frank Sinatra) . More info is in the writeup.
Looks like it would be easy enough to take the
actual guts of the program and port it to [insert your favourite language
here].
