Meet Masha Abazari Kia from the University of Essex
Mahsa’s PhD studentship has sought to eliminate human processing of engineer notes delivering significantly improved customer experience.
Technical engineering notes in their current form can provide useful insights into customer order progress however at times they aren’t easy to understand or use. Working with the University of Essex this BT sponsored PhD studentship sought to eliminate the need for human processing of engineer notes wherever possible.
Using Natural Language Processing (NLP) and Machine Learning (ML) techniques the PhD explored methods to summarise and explain these notes. Further to this, question answering techniques were also studied to automatically generate answers to given questions.
The benefit of doing this is to enable quicker, proactive reactions from knowledge contained within the notes and deliver a better experience to our customers.
Working with academic supervisors from the University of Essex, the project was shaped to ensure there was scope to deliver a novel PhD topic that had potential to provide real world business benefit.
The BT industrial supervisor, Aygul Garifullina, organised regular calls with Mahsa and her academic supervisors to review progress and discuss technical matters. As NLP and ML are fast developing areas it was critical to follow the hot topics and trends.
With the benefit of Adastral Park being so close to the University of Essex, Mahsa was able to regularly visit Adastral Park wherever possible, building effective working relationships and allowing the her to collaborate with multiple BT domain experts and stakeholders. This provided enhanced context behind the relevance and direction of the research.
Whilst the PhD spanned across multiple Covid restrictions being in place the relationship between Mahsa and Aygul remained strong through the ability to remain flexible and adapt to the given circumstances.
Finally, as the industrial sponsor BT provided datasets for training machine learning models allowing Mahsa to see real world examples of input and develop novel methods. Due to the confidential nature of the data this created restrictions in terms of results publication, although learnings from this will be used going forwards.
At the start of the journey we expected the PhD would contribute towards the research area of natural language processing, with application to analysis and understanding of engineering notes, helping BT to develop its capabilities in this domain. The output exceeded our expectations through:
More importantly Mahsa successfully passed her PhD in December 2022. This project is part of continuing relationships with our academic partners to foster collaboration and knowledge sharing in this field.
Learning and early prototypes from this work will be essential for building future solutions for automated analysis and processing. Due to an ongoing review of the software stack, downstreaming would require significant transformation efforts. Therefore, the team are actively exploring options in this space, especially considering recent advancements in technology.
Thank you to the University of Essex Supervisors Dr. Jon Chamberlain, Dr. Shoaib Jameel, the Student Mahsa Abazari Kia and our BT Industry Supervisor Aygul Garifullina.
Also we’d like to thank Prof. Ansgar Scherp who helped to set up and start the project as an academic supervisor from the University of Essex and Dr. Mathias Kern for continuous support from BT side.
