Algorithms that process words can help Google AI systems understand and anticipate your needs even when you are not expressing them in a set of keywords but in plain, unclear natural language, the language we speak every day. If you currently try to pose questions, not just chains of keywords, to the Google search engine, you’ll notice that it tends to answer correctly. Since 2012, with the introduction of the Hummingbird update, Google became better able to understand synonyms and concepts.
