Album de notas: Google mejora la búsqueda con sinónimos

Our synonyms system is the result of more than five years of research within our web search ranking team. We constantly monitor the quality of the system, but recently we made a special effort to analyze synonyms impact and quality. Most of the time, you probably don't notice when your search involves synonyms, because it happens behind the scenes. However, our measurements show that synonyms affect 70 percent of user searches across the more than 100 languages Google supports. We took a set of these queries and analyzed how precise the synonyms were, and were happy with the results: For every 50 queries where synonyms significantly improved the search results, we had only one truly bad synonym.
An example of a bad synonym from this analysis is in the search [dell system speaker driver precision 360], where Google thinks "pc" is a synonym for precision. Note that you can still see that on Google today, because while we know it's a bad synonym, we don't typically fix bad synonyms by hand. Instead, we try to discover general improvements to our algorithms to fix the problems. We hope it will be fixed automatically in some future changes.
We also recently made a change to how our synonyms are displayed. In our search result snippets, we bold the terms of your search. Historically, we have bolded synonyms such as stemming variants — like the word "picture" for a search with the word "pictures." Now, we've extended this to words that our algorithms very confidently think mean the same thing, even if they are spelled nothing like the original term. This helps you to understand why that result is shown, especially if it doesn't contain your original search term. In our [pictures developed with coffee] example, you can see that the first result has the word "photos" bolded in the title:

(Note that because our synonyms depend on the other words in your search and use many signals, you won't necessarily always see the word "photos" bolded for "pictures", only when our algorithms think it is useful and important to bold.)
