Introduction

  • Argumentation makes up an important part of human communication
  • Social argumentation differs from formal argumentation
  • Current models struggle to capture the social and rhetorical impact of arguments

Problem Space: The Good

  • Social media is a rich opportunity for analysing "Big" argument structures
  • Allows us to see how massive communities form and conduct discussions

Problem Space: The Bad

  • Design of social spaces causing debate to stagnate (e.g. echo-chambers/filter bubbles)
  • Widespread controversy and abuse (e.g. #GamerGate)
  • Modelling these problems may help us solve them

Argumentation

  • Current models focus on formal logic and reasoning
  • Useful for AI/agent based system
  • Less useful for modelling human beings

Dialectic/Eristic

  • Dialectic: Attempting to solve a problem or discover truth
  • Eristic: Quarrelling to "win"

Kerferd (1981). The Sophistic Movement. Cambridge University Press.

Logic/Rhetoric

  • Logic: Using "facts" to draw conclusions
  • Rhetoric: Using knowledge of the audience

Existing Models: AIF

  • Argument Interchange Format
  • Represents argumentation as a directed graph
  • Aims to link the concepts of natural language argumentation with abstract mathematical modelling

Chesñevar et al. (2006) Towards an argument interchange format. Knowledge Engineering Review

Existing Models: AIF

AIF Example

Existing Models: AIF+

AIF+ Example

Existing Models: SIOC

  • Semantically-Interlinked Online Communities
  • Cross-platform, cross-service representation of data from the social web
  • Uses FOAF to link people to their online accounts

Breslin et al. (2006). SIOC: an approach to connect web-based communities. International Journal of Web Based Communities

Existing Models: SIOC

SIOC: Model

Example: Attacks

"Alice isn't qualified to make that argument; she doesn't even have a PhD"

Example: Attacks

"Bob doesn't know what he's talking about - he's a ****ing idiot"

Example: Attacks

"**** off and die"

ASWO: Model

  • Argumentation on the Social Web
  • Ties together the AIF and SIOC frameworks
  • Extends these to cover social argumentation

ASWO: Model

ASWO: Personas

ASWO: Model

ASWO: Personal Attacks

ASWO: Investigations

  • Sampled a set of 270 posts from Twitter, Facebook and Reddit
  • Annotated these posts using AIF/SIOC/ASWO
  • Examined the use of logical and rhetorical tactics

ASWO: Analysis

  • Even a subset of social/rhetorical tactics are prevalent in online argumentation
  • May be possible to draw some correlations between post content and tactics

Future work

  • Introduce further ASWO extensions
  • Examine distribution of rhetorical tactics on different social media platforms
  • Examine how different tactics alter a user's perception of the argument as a whole

Conclusion

  • Current models of argumentation do not capture rhetorical force or social impact
  • Social media is an excellent opportunity to analyse argumentation on a large scale
  • The social (and anti-social) aspects of argumentation cannot and should not be ignored
