Elena Kochkina

I am a final year PhD student in Computer Science supervised by Prof. Rob Procter and Dr. Maria Liakata. I am affiliated with the Warwick Institute for the Science of Cities (WISC) CDT and funded by the Leverhulme Trust via the Bridges Programme. My background is Applied Mathematics and Complexity Science.

I am a visiting student at the Alan Turing Institute in London.

Research

My research is focused on Rumour Stance and Veracity Classification in social media conversations. Veracity classification means a task of identifying whether a given conversation discusses a True, False or Unverified rumour. Stance classification implies determining the attitude of responses discussing a rumour towards its veracity as either Supporting, Denying, Questioning or Commenting. In my work I study the relations between these tasks, as patterns of support and denial can be indicative of the final veracity label. As the input data is in the form of conversations discussing rumours, I utilise the conversation structure to enhance predictive models. I work with deep learning models as this approach allows flexible architectures and has benefits of representation learning. Recurrent and recursive neural networks allow to model time sequences and/or conversation tree-like structures.

Research interests

My general research interests are Machine Learning, Data Mining, Deep Learning, Natural Language Processing and Image Processing.
