Google Flu Trends : ウィキペディア英語版 | Google Flu Trends Google Flu Trends is a web service operated by Google. It provides estimates of influenza activity for more than 25 countries. By aggregating Google search queries, it attempts to make accurate predictions about flu activity. This project was first launched in 2008 by Google.org to help predict outbreaks of flu.〔 Google Flu Trends is now no longer publishing current estimates. Historical estimates are still available for download, and current data are offered for declared research purposes. == Introduction == The idea behind Google Flu Trends (GFT) is that, by monitoring millions of users’ health tracking behaviors online, the large number of Google search queries gathered can be analyzed to reveal if there is the presence of flu-like illness in a population. Google Flu Trends compares these findings to a historic baseline level of influenza activity for its corresponding region and then reports the activity level as either minimal, low, moderate, high, or intense. These estimates have been generally consistent with conventional surveillance data collected by health agencies, both nationally and regionally. Roni Zeiger helped develop Google Flu Trends.
