Google Automates Understanding of Synonyms

John Mueller, Google’s Search Advocate, addresses how search engines use synonyms in response to a question submitted to the Google Search Central SEO office hours. Muller confirmed that Google’s understanding of synonyms is fully automatic. It means humans do not manually write code to teach the search engine’s algorithms the synonyms of every word. This process seems like an unfeasible complicated task in a practical world as it is impossible to manually keep up with the large influx of data every day. Mueller also referred to a conference video from 2019, where Paul Haahr, a Google Engineer, explains in-depth how the search engine’s synonym system works. The video consists of real examples where Google has previously got synonyms wrong and how the engineers learned from their mistakes.
