Enstract is the best tool to extract entities from your content and improve SEO and UX. Enstract leverages Google’s Natural Language Processing (NLP) technology to extract the entities (people, places and things) associated with content to categorise (or cluster) your posts and/or pages.
WordPress already has categories and tags you can add, though Enstract will instead tell you what categories are best for your content based on these entities and their salience (a way to measure the content relevancy).
