Transcript Barack Obama On Hillary, Iraq And
More Obama I think that the voters should be
concerned that she is running the textbook,
classic Washington campaign, which is to avoid
giving clear answers and getting pinned down, for
fear that somehow you're going to be tagged,
either in the primary or the general election. I
think that's an old way of doing business. I
think that's the kind of politics that has lead
to gridlock and an ineffective Washington. That's
the kind of politics I want to change.
Barack Obama "I Think I'm a Pretty Cool Dad!" "I
think I'm a pretty cool dad," Obama told Us
earlier in the campaign. Case in point before
jetting off to the White House Monday, he kissed
his daughters, Malia, 10, and Sasha, 7, goodbye
and dropped them off at school. During the
campaign, Michelle told Us "He's an incredible
husband and father. Not sure if the world knows
yet, but they should!"
The story of Barack Obama's mother Each of us
lives a life of contradictory truths. We are not
one thing or another. Barack Obama's mother was
at least a dozen things. ... I think she was
always searching for something. She wasn't
comfortable seeing her life confined to a certain
box." Obama's mother was a dreamer. ...

Future Work
  • Interface and retrieval evaluation (using Spinn3r
    dataset) and improvement
  • Expand mood classification dimensions
  • Return to a focus on stories
  • Create other dimensions for search
