Crisis events monitored (green) and SOS Alerts launched (red), 2016 – 2020.

To complement Wikipedia’s systems, we’ve added additional protections and detection systems to prevent potentially inaccurate information from appearing in knowledge panels. On rare occasions, instances of vandalism on Wikipedia can slip through. Only a small proportion of edits from Wikipedia are potential vandalism, and we’ve improved our systems to now detect 99 percent of those cases. If these issues do appear, we have policies that allow us to take action quickly to address them.

To further support the Wikipedia community, we created the WikiLoop program last year that hosts several editor tools focused on content quality. This includes WikiLoop DoubleCheck, one of a number tools Wikipedia editors and users can use to track changes on a page and flag potential issues. We contribute data from our own detection systems, which members of the community can use to uncover new insights.  


Helpful context from fact checks and Full Coverage

We design Search and News to help you see the full picture, by helping you easily understand the context behind information you might find online. We make it easy to spot fact checks in Search, News and, most recently, Google Images by displaying fact check labels. These fact checks and labels come from publishers that use ClaimReview schema to mark up fact checks they have created. This year to date, people have seen fact checks on Search and News more than 4 billion times, which is more than all of 2019 combined. 

We understand the importance of the fact checking ecosystem in debunking misleading information, which is why we recently donated an additional $6.5 million to help fact checking organizations and nonprofits focus on misinformation about the pandemic.

We also just launched an update using our BERT language understanding models to improve the matching between news stories and available fact checks. These systems can better understand whether a fact check claim is related to the central topic of a story, and surface those fact checks more prominently in Full Coverage—a News feature that provides a complete picture of how a story is reported from a variety of sources. With just a tap, Full Coverage lets you see top headlines from different sources, videos, local news reports, FAQs, social commentary, and a timeline for stories that have played out over time.


Expanded protections for Search features

We have policies for what can appear in Search features like featured snippets, lists or  video previews that uniquely highlight information on the search results page. One notable example is Autocomplete, which helps you complete your search more quickly.

We have long-standing policies to protect against hateful and inappropriate predictions from appearing in Autocomplete. We design our systems to approximate those policies automatically, and have improved our automated systems to not show predictions if we detect that the query may not lead to reliable content. These systems are not perfect or precise, so we enforce our policies if predictions slip through.

We expanded our Autocomplete policies related to elections, and we will remove predictions that could be interpreted as claims for or against any candidate or political party. We will also remove predictions that could be interpreted as a claim about participation in the election—like statements about voting methods, requirements, or the status of voting locations—or the integrity or legitimacy of electoral processes, such as the security of the election. What this means in practice is that predictions like “you can vote by phone” as well as “you can’t vote by phone,” or a prediction that says “donate to” any party or candidate, should not appear in Autocomplete. Whether or not a prediction appears, you can still search for whatever you’d like and find results. 

Information online is constantly changing—as are the things people search for—so continuing to deliver high-quality information is an area of ongoing investment. We’ve made great strides and built upon successful improvements to our systems, and we’ll continue to look for new ways to make Search and News as reliable and helpful as possible, no matter what you’re looking for.
