Topics
• Examples of argumentation support• Supporting Collaborative Online Arguing• Structuring scientific argument:
Micropublications model
General Approach (from Informatics)
1. Analyze requirements2. Consider which argumentation models to use3. Build a prototype support tool4. Evaluate and iterate
500 Wikipedia debates each week: Should we delete this article?
Requirements: Support argumentation tasks
• Convince others of your position, using community norms
• Determine the overall consensus decision
Compare two argumentation theories
• Walton’s Argumentation Schemes (Walton, Reed, and Macagno 2008)
– Informal argumentation (philosophical & computational argumentation)
– Identify & prevent errors in reasoning (fallacies)– 60 patterns
• Factors/Dimensions Analysis (Ashley 1991; Bench-Capon and Rissland, 2001)
– Case-based reasoning– E.g. factors for deciding cases in trade secret law,
favoring either party (the plaintiff or the defendant).
Walton’s Argumentation SchemesExample Argumentation Scheme: Argument from Rules – “we apply rule X”
Critical Questions1. Does the rule require carrying out this type of action?
2. Are there other established rules that might conflict with or override this one?
3. Are there extenuating circumstances or an excuse for noncompliance?
Walton, Reed, and Macagno 2008
“Rule” Argumentation Scheme
“Arguments about Deletion: How Experience Improves the Acceptability of Arguments in Ad-hoc Online Task Groups” CSCW 2013
“Evidence” Argumentation Scheme
“Arguments about Deletion: How Experience Improves the Acceptability of Arguments in Ad-hoc Online Task Groups” CSCW 2013
Evidence + Rule -> Conclusion
“Arguments about Deletion: How Experience Improves the Acceptability of Arguments in Ad-hoc Online Task Groups” CSCW 2013
Supporting Tasks with Walton
• Convince others of your position, using community norms– To win an argument, use popular schemes:
• Argument from Evidence to Hypothesis (19%)• Argument from Rules (17%)
• Determine the overall consensus decision– Ask critical questions to check others' arguments
Factors/Dimensions Analysis
• Factors (case-based reasoning)– All or nothing• Either present ("applicable") or absent• When present, a factor always favors the same side
• Dimensions– More complex/subtle• Can be applicable to a varying degree ("sliding scale")• Favor plantiff on one extreme; defendant on the other
Ashley 1991; Bench-Capon and Rissland, 2001

Wikipedia Factors Analysis
Factors determined by iterative annotation
4 Factors cover– 91% of comments– 70% of discussions
“Other” as 5th catchall
Factor Example (used to justify `keep')
Notability Anyone covered by another encyclopedic reference is considered notable enough for inclusion in Wikipedia.
Sources Basic information about this album at a minimum is certainly verifiable, it's a major label release, and a highly notable band.
Maintenance …this article is savable but at its current state, needs a lot of improvement.
Bias It is by no means spam (it does not promote the products).
**Other I'm advocating a blanket "hangon" for all articles on newly-drafted players

There is simply no coverage in reliable sources to establish notability.
Sources Basic information about this album at a minimum is certainly verifiable, it's a major label release, and a highly notable band.
There are no independent secondary sources (books, magazine articles, documentaries, etc.) about her.
Maintenance …this article is savable but at its current state, needs a lot of improvement.
Too soon for a page likely to be littered with rumour and speculation.
Bias It is by no means spam (it does not promote the products).
The article seems to have been created by her or her agent as a promotional device.
**Other I'm advocating a blanket "hangon" for all articles on newly-drafted players
it appears to be original research by synthesis

Supporting Tasks with Factors
• Convince others of your position, using community norms– To win an argument, talk about the right topics
• Notability, Sources, Maintenance, Bias
• Determine the overall consensus decision– Group messages by factor– Summarize prevalence
Factor-based Summarization
Argument Schemes vs. Factors?
• Argument Schemes (kappa=.48)Details of how to put together an argument– Could support WRITING detailed arguments– Critical Questioning
• Factors (kappa=.64-.82, based on factor)Topics of discussion– Basic support for writing arguments– Summarization supports decision-making
Argument prevalence depends on the corpus
• Wikipedia– Argument from Evidence to Hypothesis (19%)– Argument from Rules (17%)
• Arucaria– Argument from example (38%)– Argument from cause to effect (27%)– Practical reasoning (14%)– Argument from consequences (11%)– Argument from verbal classification (10%)

Argumentation mining today
• No unified vision of the field. Multiple:– Interrelated problems– Application domains– Tools handling one aspect of annotation
• Few corpora• Need for– Common definition(s) of argumentation– "Challenge problems"– Shared corpora– Applications
Example: "Stop at a red light"
1. Does the rule require carrying out this type of action?Were you driving a vehicle?
2. Are there other established rules that might conflict with or override this one?Did a police officer direct you to continue without stopping?
3. Are there extenuating circumstances or an excuse for noncompliance?Were you driving an ambulance with its siren on?
Critical Questions from Argument from Rules based on Walton, Reed, and Macagno 2008
None of Wikipedia's top-used schemes are prevalent in Arucaria.
Classifying Arguments by Scheme. Vanessa Wei Feng. Master's thesis, Toronto, 2010.
Goal: large-scale arguing
• Search for issues, claims, and opinion clusters• Link to evidence when writing your opinion• Publish and navigate claims networks
Online argumentation support interfaces can:
• Promote "listening" in online conversations• Support incremental formalization• Slice and dice the views• Collect crisp examples• Support distributed sensemaking
Argumentation mining could be the basis for support tools
• Help participants write persuasive arguments– How: provide personalized feedback on drafts– Requires: knowing which arguments are accepted;
identifying argumentation in a drafts • Find weaknesses in others’ arguments– How: suggest & instantiate relevant critical questions– Requires: identifying argumentation schemes
• Summarize the overall conclusions of the debate– How: identify the winning and losing rationales– Requires: identifying rationales and contradictions
