Things I Don’t Have to Talk About
• There’s lots of text in the world
• Most of the world’s knowledge is in text
• You should stop ignoring it
• If you’re going to work with text it needs structure
![Page 3: Open Calais @ Transparent Text](https://reader036.fdocuments.net/reader036/viewer/2022081413/547bab72b37959822b8b4d6c/html5/thumbnails/3.jpg)
Today
• Going to cover three things
– The text problem in one slide
– What is OpenCalais? What does it do?
– A few examples of how people are and could use it
• Sorry – no pretty visualizations

The Text Problem (aka Why OpenCalais?)
• Target areas where:– The economics
don’t support metadata creation
– The value of metadata is potentially high
– The value of aggregated metadata is potentially extremely high
