As the volume of data increases exponentially, professionals who deal with vast amounts of information can struggle to keep up. The National Research Council's of Canada's (NRC) text analytics team conceives, builds, and evaluates tools that help extract information from textual data: explicit, implicit and inferred information, composite information (summaries), subtext information (sentiment, sarcasm, metaphor) and meta-information.
The team collaborates with government, industry, and academia to drive text analytics technologies for a range of problem-driven and data-driven applications. We have been working in areas such as situational awareness, clinical research informatics, sentiment and emotion analysis, and intelligence.

Why work with us
Our experts have extensive experience and knowledge of the latest text analytics approaches, and know how and when to best apply the appropriate techniques. Our experience spans from tried-and-trusted statistical algorithms to state-of-the-art artificial neural networks and deep learning approaches.
Our innovative capacity and technical competency in machine learning methods and (big-) data-oriented methods have resulted in world-leading research. We have collected multiple first-place rankings in text analysis research challenges such as i2b2 NLP for Clinical Data and the Sentiment Analysis track of SemEval.
Public confidence and trust is key for companies and organizations responsible for the sound management and use of data. Our team is committed to the ethical development and use of text analytics technologies. We regularly convene thought leaders in this area to share their expertise with the research and policy community, and we build ethical evaluation processes into our projects from the outset in collaboration with our partners.
