Instantly, King Xiao soon becomes Pharaoh, but he still has no girlfriend. One day, the cousin of Xiao Wang's aunt's girlfriend introduced him to a girl. Xiao Wang intends to disguise himself as a big money and a small flower date.
Unexpectedly, the first face of Xiao Wang seen by Xiaohua, the customized data analysis service of the mobile phone sent a reminder—
Dear users, The current Dawang assets you meet with are about RMB 5,000.
Xiao Wang, who left X with the flowers, cluttered in the wind...
Readers rest assured, but fortunately, the above is just edited by Lei Feng. However, on September 13th, at the T112016 and TalkigData Smart Data Summit, Pan Yi, head of the iitiative China MIT New Media Lab, told everyone that the phone data can be used to determine his or her social network and thus the difference between the poor and the rich.
In other words, if you have any money, your cell phone will know better than your wife.
An experiment triggered by a "puppet wool"This shuddering experiment started in 2010 by Pan Yu’s team. At the time, there was a MIT doctoral student and family dormitory in WestGate, because the graduate student recruitment was for the whole society, so all classmates had it. For example, a local student who is laying down an industry to study and a poor student may be in a dormitory.
Although, in 2010, everyone's awareness of privacy protection was not weak, no one would like to contribute their own personal data to experiment, but researchers used to send 120 people each one of the latest Samsung mobile phones (please play advertising fees) As a condition, the experimenter is required to maintain the opening of the mobile phone every day for a year and a half. So what is it to say? This is an experiment that began with "Wool"...
You may not be the real one on social networks. If you publish a questionnaire for everyone and investigate who your best friend is, such research may not be accurate. However, through the sensor acquisition system of the Android mobile phone, through Bluetooth, face-to-face gathering information of two meeting people, the two people are truly met, and this information is more reliable. The mobile phone can also collect your communication information, what kind of APP is installed, even if it is a simple mobile phone, it can also analyze your real situation.
Mobile phones give us a new understanding of social networking. Pan Yu said.
Communication records reveal whether you are poor or richPan Mao and his research team analyzed the communication records of these mobile phones and obtained a key indicator - diversity and homogenization diversity of mobile phone call records.
The so-called diversity refers to whether you talk to one person or whether you are talking to more than one person. On the other hand, homogenization of diversity refers to the number of people whose call duration is evenly distributed.
For example, the call is 90 minutes. The 90-minute call is conducted with three people. The talk time for A, B, and C is 5 minutes, 80 minutes, and 5 minutes, respectively. In the same 90 minutes, the talk time for A, B, and C is 30 minutes. In both cases, through a formula calculation, the latter is judged to be more extensive social networks, more likely to be rich and successful people.
The editor, X, took two relatively common examples. A rich man fell in love with a beautiful woman and often stalked the phone, so that his homogenization diversity actually favored the poor. In addition, if a rich man had a long way to go. , I was hospitalized sick for a long time, is to make a call with a good friend to solve boredom, then how to calculate?
Pan Yi explained to Lei Fengwang: "So these data need to be collected for a certain period of time, even a longer period of time, such as one and a half years, which is more objective."
In addition, the editors of Lei Fengwang (searching for the "Lei Feng Net" public number) editor and Pan Yi once again confirmed that the data needed for this model and conclusion can only be obtained from the mobile communication data. However, Pan Xi also emphasized that the same results were obtained after analyzing consumer behaviors using the credit card data of these experimental groups.
Actually can be used to analyze the economic development of the cityIt may be that the communication record reveals whether you are poor or rich and will make people fall into the pre-existing chicken or egg debate. Surprisingly, however, a magical discovery was made from the analysis of the telephone company's communications records that the diversity of contacts is strongly correlated with the economic indicators of the city, and that diversity is not related to the urban population density.
As shown in the figure, the X-axis is the call diversity and the Y-axis is the level of urban development.
Just by measuring the user's call history, you can also predict the user's debt repayment ability, credit index, and the possibility of finding a job.
After inserting the news, Lei Feng.net editors have opened their minds again. Does that mean that the real estate agent who calls and sells on a daily basis is not the most likely to be a rich person. Is it possible to find a job?
Diversity will increase the flow of knowledge, and the city will help you superlinearly increase social diversity. Pan Yu’s team’s theoretical model is as follows:
He once again gave a corroboration:
A year after our paper was published, researchers used the call records between users of mobile phones from several important cities in Portugal to test whether the theory of our relational information flow was correct. The researchers said that these results verify the knowledge flow in the city. The increase in the size of the speed-year-old city is in line with the recent theoretical results.â€
Pan Yu summed up: "Through computational sociology, perhaps smart phones can provide wisdom for our social behavior, not just a social measurement tool."
