  18. 18. matching local to global statistical literals humans influences
  19. 19. statistical the law of large numbers
  20. 20. literals String matching …. Yeah baby! What do we want? UNIQUE MATCHES! When do we want them? NOW! NOW! NOW! OH NO!!! hang on a minute ….
  21. 21. literals String matching …. DAMN YOU! WOO-HOO! Not hits hits Multiple EXACT MATCH means we’ve gotta URI no URI no need for humans needs humans but can you really REALLY trust it? Innumerate?
  22. 22. an aside …. the innumerate Scots The first bridge The Forth bridge is the Forth neither the Fourth nor the 4th The 2nd bridge is the Forth Road bridge

  29. 29. crowds Which person is Old Fox? `<name> Capt. Campbell </name> <name> Maj Duncanson </name> Is Glencoe here? <name> old Fox </name> <place> Glencoe </place> <name> McDonalds </name> Order to Capt. Campbell by Maj.

  30. 30. crowds & geonames We think this is Cambrai … Do you think this Cambrai is here? it Or do you think it’s here?
  31. 31. crowds & dbPedia Is the horse in this picture … it none of these
  32. 32. crowds & LCSH Would you describe this horse in any of these ways? it Show jumpers (horses) Horses in motion pictures Toy Horses Horses War horses Travel with horses none of these
  33. 33. Things to think about …. • using a voc without URIs? – should we change? • are there good ways to string match? – are they trustworthy? • are crowds helpful? • what vocs are mapped to what other vocs? – can/should we help map vocs beyond our domain?
