institutes for cross-disciplinary physics and complex systems have developed a new method --
tracking, migration using data from the social media platform twitterwhich provides more
frequent nuanced and perhaps more accurate information.
The researchers analysed thousands of tweets to develop a model to predict whether
individuals are likely natives in migrants to the places they live information about users and
their posts to make a determination.for example if a user regularly to its in German from an
address in Philadelphia the model would label the user as a German immigrant.
Researches aggregated that data to identify 35 immigrant communities in 15 cities around the
world. They then predicted through user actions the neighborhoods in those cities where is
likely a migrant community lives. If a large portion of the city's non-immigrant residents also
lives in those neighborhoods the immigrant community is considered to be well-inter grated
into the city.
Through the research London Rose to the top and took the title of the most enter grated City.
"We found that in the central part of the
city [ Chelsea, Kensington,and
Marylebonel,communities such as Russian, French, and Arabic spread almost uniformly
around the areas, "kar dungi says Fabio lamanna civil transportation engineer who led the
