Overview

National Research Council Canada (NRC) is seeking a postdoctoral candidate
with an interest in ethical aspects of Natural Language Processing (NLP).
The goal of the project is to develop tools and techniques to address two
critical issues in ethical NLP applications design and use: fairness and
explainability. AI applications often inadvertently perpetuate and
accentuate unfair biases that can originate from multiple sources, such as
training data, labeling process, data sampling, etc. Biased outputs can
negatively affect certain demographic groups of users and even lead to
discrimination. The ability of an AI system to provide understandable
explanations for its decisions is a crucial factor in real-life
applications both for developers to better understand the system?s behavior
and for users to gain trust in the system. The techniques will be developed
with the focus on one application area, abusive language detection in
social media, while ensuring their applicability and/or transferability to
other natural language understanding tasks and domains.

The successful applicant will join the Text Analytics group at NRC Digital
Technologies Research Centre, which has a world-renowned reputation in
Natural Language Processing and Computational Linguistics, including
sentiment and emotion analysis, information extraction, medical informatics
and health-related applications. The applicant will work in close
collaboration with the project leads, Dr. Svetlana Kiritchenko and Dr. Isar
Nejadgholi, but will also have access to diverse expertise of other NRC
researchers.
