Ethos Mining: foundations, applications and future work
Event date:  December 3, 2018 4:00 PM  to 5:00 PM

Ethos, defined by Aristotle as the character of the speaker, plays a fundamental role in day to day society being present in conversation to political debate. Despite this fact the automatic extraction of ethos from natural language, ethos mining, has rarely been studied with the primary focus in the argumentation community being upon the reasoning expressed in language (logos). In this talk I will show the foundations of ethos mining, focussing upon the intricacies of UK parliamentary debate and the natural language processing methods used in extraction. I will then describe the current applications of ethos mining, in particular, the initial qualitative and quantitative visualisations which can be expressed from ethos mining for individual politicians and political groupings. Finally, I will explore possible future avenues of work in ethos mining, especially improvements which can be made from a deeper understanding of the natural language and the possibilities of further visualisation.

 

Biography: 

Rory is a PhD student within the Computational Ethos Lab (CELab), part of the Centre for Argument Technology at the University of Dundee. His research has focussed on the creation of the first corpus of manually annotated ethos and the first automatic extraction of ethos in political debate, using Machine Learning and Deep Learning, as well as the visualisation of political relationships and data trends. During his PhD, Rory has published at several international conference venues most notably winning the best student paper award at the International Conference on Computational Models of Argument (COMMA) 2016 and presenting at the International Joint Conference on Artificial Intelligence (IJCAI) 2018.
