Google Tweaks Search to Better Understand Your Gibberish Queries

Using an open-source neural network, Google says search can better understand context to return better results.

Searching for information online sometimes takes creativity—depending on how you word a query, Google can bring back some wonky results. That’s why Google announced today that it’s improved search to better understand natural language for “queries [it] can’t anticipate.”

Part of the issue is that we imperfect humans don’t always know how to spell what we’re looking for, or even word it in a way that makes sense to computers. If you phrase a query conversationally, you run the risk of getting garbage results back. That’s why it’s way more common to use what Google calls “keyword-ese”, where you’re just typing related words together. Sort of the equivalent of baby talk, for a computer algorithm.

To combat this, Google says it’s using an open-sourced neural network to train search for better natural language processing. It’s called Bidirectional Encoder Representations from Transformers (BERT), and in a nutshell, lets search algorithms consider linguistic context instead of relying solely on keywords. In particular, prepositions like “for” and “to” can trip up a regular search. One example that Google provided was the search results for the query “2019 brazil traveler to usa need a visa.” Before applying BERT, the results would give backlinks about U.S. citizens traveling to Brazil.

Google’s seen success with its natural language processing in recent years with Google Assistant. Of the three major voice assistants—Siri and Alexa being the other two—Assistant is the best at understanding and answering conversational commands and queries. It’s of course, not perfect, but as someone with all three in my apartment, I don’t have to think quite as hard about the exact phrasing I use when speaking to my Google Nest Hub.

According to Google, using BERT will help improve one-in-ten English-language searches in the U.S. That’s not to say that BERT won’t roll out to other languages sometime down the line. Google says its taking improvements from English models and is currently seeing significant improvements in Korean, Hindi, and Portuguese.
