Abstract

The GATE open source NLP toolkit has been in continuous development for 20 years at the University of Sheffield. In this talk, I will give an overview of some of our language analysis work focusing on social media, giving examples of real-life case studies. In particular, I will focus on the interactions between language, society and behaviour, based on three main areas of interest: investigating the correlation between the public’s environmental behaviour and their use of social media; tools for assessing critical information during disasters such as earthquakes; and investigating hate speech and other interactions with UK politicians on social media. Our social media toolkit covers twitter collection, text analysis, indexing, querying and visualisation of results, as well as crowdsourcing and evaluation tools, while the analysis components include entity and topic recognition, semantic annotation, entity linking, informativeness assessment, and sentiment analysis. In the talk, I will demonstrate how the toolkit has been used to understand people’s behaviour on social media and on the further impacts this can have in everyday life.

Diana Maynard is a Senior Researcher at the University of Sheffield, where since 2000 she has led the development of Sheffield’s open-source multilingual text analysis tools (GATE), and has led research teams on a number of UK and EU projects. Her main research interests are in tools for language technology, information extraction, sentiment analysis, social media analysis and terminology. Dr. Maynard recently worked on the EU DecarboNet project, developing social media analysis tools for investigating attitudes towards climate change, and currently works on various projects around social media and news media analysis, including use of social media during crises in the EU COMRADES project.
