A quick presentation to talk about the benefits of structured knowledge, focused on parallax & freebase, and how their knowledge representation fits into the wider scope of the semantic web.

1. Michel Dumontier, PhD

2. Current search engines use keywords
You might get 104M pages back
You can only look at one page at a time.
Hard to aggregate and visualize results
How can we ask more complicated questions,
and get real answers?

19. Key Concepts
Structured knowledge leads to better search and
more accurate information retrieval over sets of
related data
Best knowledge repositories will be user-
extensible, but leverage form fillable fields as
defined by types
The W3C’s Semantic Web will make sure that info
doesn’t have to be centralized!
