Papers at ITBAM 2012, ePart 2012, and EKAW 2012

Recent papers at various conferences. One is in the 3rd International Conference on Information Technology in Bio- and Medical Informatics (ITBAM 2012), Vienna, Austria. Another is in the 4th International Conference on eParticipation (ePart 2012), Kristainsand, Norway. And a final paper is in the 18th International Conference on Knowledge Engineering and Knowledge Management, Galway, Ireland.

Argumentation to represent and reason over biological systems
Adam Wyner, Luke Riley, Robert Hoehndorf, and Samuel Croset.

Abstract
In systems biology, networks represent components of biological systems and their interactions. It is a challenge to efficiently represent, integrate and analyse the wealth of information that is now being created in biology, where issues concerning consistency arise. As well, the information offers novel methods to explain and explore biological phenomena. To represent and reason with inconsistency as well as provide explanation, we represent a fragment of a biological system and its interactions in terms of a computational model of argument and argumentation schemes. Process pathways are represented in terms of an argumentation scheme, then abstracted into a computational model for evaluation, yielding sets of ‘consistent’ arguments that represent compatible biological processes. From the arguments, we can extract the corresponding processes. We show how the analysis supports explanation and systematic exploration in a biology network.

Model based critique of policy proposals
Adam Wyner, Katie Atkinson, and Trevor Bench-Capon

Abstract
Citizens may engage with policy issues both to critique official justifications, and to make their own proposals and receive reasons why they are not favoured. Either direction of use can be supported by argumentation schemes based on formal models, which can be used to verify and generate arguments, assimilate objections etc. Previously we have explored the citizen critiqing a justification using an argumentation scheme based on Alternating Action-based Transition Systems. We now present a system which uses the same model to critique proposals from citizens. A prototype has been implemented in Prolog and we illustrate the ideas with code fragments and a running example.

Dimensions of argumentation in social media
Jodi Schneider, Brian Davis, and Adam Wyner

Abstract
Mining social media for opinions is important to governments and businesses. Current approaches focus on sentiment and opinion detection. Yet, people also justify their views, giving arguments. Understanding arguments in social media would yield richer knowledge about the views of individuals and collectives. Extracting arguments from social media is difficult. Messages appear to lack indicators for argument, document structure, or inter-document relationships. In social media, lexical variety, alternative spellings, multiple languages, and alternative punctuation are common. Social media also encompasses numerous genres. These aspects can confound the extraction of well-formed knowledge bases of argument. We chart out the various aspects in order to isolate them for further analysis and processing.
