Abstract: A text from a predetermined domain is taken and converted to canonical named entities based on an established taxonomy. Using a shared machine learning encoder model, contextual embeddings for these named entities are produced. These embeddings are then fed into a domain-specific scoring model related to the text's domain. This model ranks the embeddings based on relevance. The derived relevance scores, along with the entities, are sent to another system for further tasks. For instance, a recommendation system might use these scores to suggest relevant named entities.
