14. Story of Wikipedia-as-CV: personal origins We needed a system to categorise movie & TV reviews

15. Story of Wikipedia-as-CV: personal origins So of course we built a categorisation system from scratch -- including its own controlled vocab

16. Story of Wikipedia-as-CV: personal origins And when people saw the system, they always said: “Hey, that reminds me of Internet Movie Database…”

22. Story of Wikipedia-as-CV: personal origins Could those “one Concept per page” webpages be used as “terms” as in a controlled vocabulary?

33. These days, by convention, when you link to Wikipedia from your webpage, more than saying “go and have a look at this other page”, you are more likely giving a definition to a concept referred to in your content…

34. These days, by convention, when you link to Wikipedia from your webpage, more than saying “go and have a look at this other page”, you are more likely giving a definition to a concept referred to in your content… Also used in this way for specific domains are Internet Movie Database (for films & TV programmes), MySpace (for bands), Amazon (for books), etc
