5. What’s the best whiskey to buy, on a budget? What’s a good Irish whiskey to bring as a hospitality gift? Do you have any advice for alcohol that's mainly available in the U.S.? Not super-expensive, but kind of nice?

6. Which answer would you rather get? I had a little think about it, and I came up with a list of options for you. …. OR http://ask.metafilter.com/131843/What-is-your-best-favorite-bourbon-for-under-100

8. Need for “sensemaking” There are a growing number of conversations on the Social Web, but we do not take advantage of all the social knowledge and social belief. There are no readily-available summaries for threads of conversation, meaning we must wade through redundant posts, often with poor rhetoric (e.g. circular reasoning). Multiple disparate conversations may occur on the same topic, and there is no easy way to bring these together. Hard to identify people with similar, different opinions from me

9. Building a Web of CLAIMS 9 What if instead of following mailing lists, blogs, online magazines, scientific journals… You could search for and follow CLAIMS? What are the important claims about “Irish whiskey”? (or “climate change” or “sensor networks” or…)? What are the points of disagreement? Who is making these claims? Should I believe them? Do they have conflicts of interest? Are they trustworthy? Do people I trust, trust them? Are their ideas credible? Do they have similar needs? Do the same aspects and features of the problem matter to them?

10. Why build the Claims Web? What do you do when people disagree? Getting meaning from inconsistent knowledge Relevant for collaborative filtering, decision-making, sensemaking, … Claims & Reasons are fundamental… and need to be connected! 10

11. Moving towards a Web of Arguments World Wide Argument Web (WWAW) isn’t here yet “a large-scale Web of interconnected arguments posted by individuals to express their opinions in a structured manner'’ (Rahwan 2007). RDFS and OWL, Argument Interchange Format (AIF). Problems with the WWAW for the Social Web AIF requires argument schemes – overly complex! Users don’t explicitly mark their positions. Need to infer. Claims Web will move us towards the WWAW Extract info from users’ posts. Cover only the Social Web. Focus on claims & reasons. 11

12. Existing argumentation technology is complex Argument schemes (e.g. Walton’s) for analysts Argument Interchange Format GOAL: Bridge existing work to suit *humans*, informal discussions

15. Approaches Mixed-initiative systems Natural language processing to discover/infer claims & reasons Executable English to make it easy to specify Games with a purpose to encourage people

18. Build a web of claims to: Gather knowledge from the inconsistent opinions of a crowd Integrate argumentative conversations across the silos of the social web Provide support for socially-embeddedsensemaking and decision-making
