I have over 10 years of experience in academia and industry, and I am Oxbridge educated and Microsoft certified.

What does an NLP expert witness do?

An expert witness is a person whose opinion is accepted by a judge as that of an expert due to their skills or qualifications in that field. Expert witnesses can be employed in various capacities such as litigation, arbitration, and tribunals. In England and Wales, a court must give permission for an expert witness to give evidence.

Expert evidence is admissible to furnish the court with information which is likely to be outside the experience and the knowledge of a judge or jury

Ministry of Justice (England and Wales), Criminal Practice Direction V Evidence 19A Expert Evidence

The role of an expert witness is to give evidence tendered as opinion rather than fact, as opposed to a fact witness.

For further information about the permitted use of expert witnesses in England and Wales, please refer to the following:

  • Crown Prosecution Service guidance to the use of expert evidence in criminal cases.
  • Civil Justice Council guidance for expert evidence in civil claims.

NLP is the subfield of machine learning that deals with processing of text and speech in human languages. Machine learning is a kind of artificial intelligence that allows computers to learn without being programmed explicitly. Machine learning systems and their capabilities can be incredibly difficult for laypeople to understand. Sometimes in litigation, it is necessary to hire an NLP expert witness to share their knowledge with a non-specialist panel or jury, in order to assist them in understanding the case.

My experience in natural language processing

Since completing a Masters degree in Computer Speech, Text, and Internet Technology (NLP) at the University of Cambridge in 2008, I have been active in various areas of NLP in industry and academia, specialising in natural language processing. Some examples of NLP projects that I have undertaken in the past include:

  • I have built a topic detection system for factory error reports, which identified common errors such as temperature excursions, damaged packaging,
  • I assisted a pharmaceutical company in predicting the costs of clinical trials.

Since 2020, I have been offering my services as an NLP expert witness and due diligence consultant for litigation, mergers and acquisitions, and arbitration.
