  11. Current Model
  12. Current Model
  13. <ul><li>And so it went in the US media: silence, indifference, with a dash of perverse misinterpretation. Consider Michael Hirsh's laughably naive commentary that imagined Bush had already succeeded in nailing down SOFA, to the chagrin of Democrats. </li></ul><ul><li>DailyKos – smintheus, Jun 15 2008 </li></ul>
  14. <ul><li>Considerably more recently, a Time Magazine swamp denizen is shocked to find John McCain apparently suggesting that support for withdrawing from Iraq and opposition to The Surge is the same as not supporting the troops. </li></ul><ul><li>BTC News, Jun 15 2008 </li></ul>
  15. <ul><li>While the traditional media is slowly starting to take John McCain’s straight talking image with increasingly large grains of salt, his base isn’t quite ready to give up on their favorite son. Jonathan Alter’s bizarre defense of McCain after he was caught telling an outright lie , perfectly captures that reluctance[.] </li></ul><ul><li>DailyKos – BarbinMD, Jun 15 2008 </li></ul>
  16. Subtle Links <ul><li>A citation can be described along the following dimensions: </li></ul><ul><ul><li>Target : what is the citation intended to refer to? The page, an entity mentioned on the page, the author, …? </li></ul></ul><ul><ul><li>Rhetorical purpose : why does the author cite?

  18. Solutions <ul><li>Some initial research shows promise – this is a solvable problem. </li></ul><ul><ul><li>Modeling Trust and Influence in the Blogosphere Using Link Polarity , Anubhav Kale, Amit Karandikar, Pranam Kolari, Akshay Java, Tim Finin and Anupam Joshi, 2007 </li></ul></ul><ul><ul><li>Blog Link Classification , Justin Martineau, Matthew Hurst, 2008 </li></ul></ul><ul><li>A solution will involve analysis of the text around the link. </li></ul>
  19. SUBJECTIVE STATEMENTS
  20. Subjectivity Research
  21. Taxonomy of Subjectivity Subjective Statement: <holder, <belief>, time> The moon is made of green cheese. . Opinion: <holder, <prop, orientation>, time> He should buy the Prius. . Sentiment: <holder, <target, orientation>, time> I loved Raiders of the Lost Arc! .

  23. Current Approaches <ul><li>Text, not person, has opinion. </li></ul><ul><li>Sentence or document level processing. </li></ul><ul><li>Some advances in reference resolution. </li></ul>
  24. Opinion Process Impetus Synthesis Expression: s Interpretation: s’ Re-Expression: s’’
  25. Transmission of Opinion <ul><li>John said that this is a great restaurant : do we trust John? Is he an authority? Does he have influence? </li></ul><ul><li>I’ve heard that this is a great restaurant : from whom? Several trusted sources? </li></ul><ul><li>This is a great restaurant : have you experienced it yourself? </li></ul>
  26. Content and Structure <ul><li>Opinions surface as statements </li></ul><ul><li>There is social – structural – context to the generation and performance of these statements </li></ul><ul><li>Statements are transmitted through the network. </li></ul>
