Named Entity Recognition
Named Entity Recognition (NER) enables extracting known terms, phrases, people, places, and other entities from content and queries allowing much more accurate query interpretation and document matching. With semantic phrases preserved and matched, it allows richer search experiences.
Part of Speech Tagging
Part of Speech Tagging (POS) helps with “word sense disambiguation.” So when the word “present” is tagged as a noun, subsequent search results omit instances where “present” is a verb for public speaking.
