Even more unlocked

Just a quick update on the Unlock Text interface I posted about last time… Eric noticed that the ‘gazref’ attribute doesn’t point back to the original source gazetteer – you needed a second interrogation of the server to get that info. That’s … Continue reading

As promised a few posts back, I’m now going to bring the geoparsing report up to date with some notes about how we got on with processing large amounts of text, once we’d finished tweaking the Geoparser setup. Google kindly … Continue reading
