Facebook experts will show how people move and where the threat of contagion

Big data could help predict a new coronavirus. Hope it’s Facebook, which has given researchers around the world new tools to use anonymized data to model and predict orders. Call up the data to which his user gave him permission through the so-called location history.
When modeling how a pandemic develops, epidemiologists approach the limits of available data. No one knows the actual number infected with the new coronavirus, only the number of confirmed infections. This means that the virus is always a few days ahead of official hearing.
Facebook is now researching two sets of tools that could help with the next step and estimating the area where the outbreak is threatening. As part of the Data for Good initiative, Facebook uses data on the movement of all users.
In anonymous and within the history of location
As in the case of public city maps published by Google last week, it uses Facebook data from users. If you have the Facebook application installed, you can turn on location history, you may be allowed to keep information about where you moved. First, this information is used to create aggregated (and therefore anonymized) maps. You have Facebook available to researchers from the non-profit sector, academics and vldm.
We will not miss new data in the dark, we will only use the data to which our user gave it access, said Steve Satterfield from Facebook in an interview with the newspaper. Hopefully, this data will lead to a rapid response to the level of the country and the individual areas.
Where does the virus go pt?
Because the new coronavirus is introduced through human money, Facebook data on social and real connectivity is an interesting source of big data. Facebook introduced you to the new types of tools.
Information about the location of the teaching kolokan map, which shows which cities on the map are connected through interpersonal contacts in the physical world.
Ko-lokan map of Italy shows which areas are interconnected through contact people.
Map provzanosti shows how different cities are linked to a specific city in the USA. Although this is just a map of Facebook friendships, it will help me to analyze the impact of when an epidemic breaks out somewhere, as is now the case in New York.
Connections of various US cities with the East Village in New York (currently the American epicenter of coronavirus infections)
And to analyze how it works and how it doesn’t work, the existing restrictions, Facebook offer a map of how far do people go from their homes?. The fact that this distance decreases greatly usually means that the people observe the quarantine or the existing destruction.
How far from home the people go, the course of time.
Only in the USA, Facebook will also run a questionnaire, which will teach users and prompt them to fill in the expected flags. Researchers at Carnegie Mellon University want to map the epidemic. Of course, this is not the same hard data as in laboratory tests, but it can be a huge amount of useful and indicative data.
In the United States, Facebook will show people how to take ct, and the data will help researchers at Carnegie Mellon University map out the diseases.
When asked if Facebook fulfills something even on an individual level, you recently met a hunter who confirmed the order of the Facebook. But for now, they have nothing specific that they can publish.
According to a New York University study (PDF), anonymized data can actually be used to predict the epidemic. On the example of COVID-19, they showed that areas that have more Facebook links to areas affected by the virus have a chance that the epidemic will start to happen in them.
