Using Twitter to Estimate and Predict the Trends and Opinions
ثبت نشده
چکیده
The most common and conventional way to collect people’s opinions has always been random sampling and asking several survey questions by phone. For instance, if a news media is interested in how popular Obama is among Americans, it would probably call up a thousand people and ask how they would rate Obama. The data collected in this manner is considered a gold standard; there has been only few attempts to find a different way to collect such data. However, this approach bears a few shortcoming such as costs, limited targeted people, etc.
