Behind the Scenes of NER Nightly Retrains
One of the most important elements behind well-performing site search is NER: Named Entity Recognition. NER is an AI technique that identifies key information in text. At Yext, NER is used to identify all the different entity types (i.e. products, people, places, dates, customer service problems) in a given Yext Answers query. The performance of NER is crucial because based on our NER model’s predictions, we directly search the Yext Knowledge Graph to find the information the query was referencing and serve the most relevant search results.
