Statement of Purpose
Neural network–based representations (or “embeddings”) have dramatically advanced natural language processing (NLP) tasks, including clinical NLP tasks such as concept extraction. Recently, however, more advanced embedding methods and representations (such as ELMo and BERT) have further pushed the state of the art in NLP, yet there are no common best practices for how to integrate these representations into clinical tasks. The purpose of this study, then, is to explore the space of possible options in utilizing these new models for clinical concept extraction, including comparing these to traditional word embedding methods (including word2vec, GloVe, and fastText).
The target audience for this activity is professionals and students interested in biomedical and health informatics.
The general learning objective for all of the JAMIA Journal Club webinars is that participants will
- Use a critical appraisal process to assess article validity and to gauge article findings' relevance to practice
After this live activity, the participant should be better able to:
- Explain how neural network-based embedding techniques are utilized in natural language processing (NLP)
- Discuss how recent (“contextual”) embedding techniques have advanced NLP, including their potential impact on NLP for electronic health records
- Identify key considerations for maximizing the impact of contextual embedding techniques for clinical NLP
