Blog Mining: Scouring Blogs for Useful Information

From the Article:

...scientists are finding—to their surprise—that useful information can actually be mined from the tedium of the blogosphere.

Andrew Gordon and his colleagues at the University of Southern California’s Institute for Creative Technologies in Los Angeles have been trying to teach computers about cause and effect. Computers are not good at dealing with causality. They can identify particular events but working out relationships is more difficult. This is particularly true when it comes to using computers to analyse the human experience.

But it turns out that computers can learn a lot about causality by reading personal blogs. Of the million or so blog entries that are written in English every day, most are comments on news, plans for activities, or personal thoughts about life. Roughly 5% are narratives telling stories about events that have recently happened to the author.

[Snip]

The web could be mined to track information about emerging trends and behaviours, covering everything from drug use or racial tension to interest in films or new products. The nature of blogging means that people are quick to comment on events in their daily lives. Mining this sort of information might therefore also reveal information about exactly how ideas are spread and trends are set.

Wednesday, 23rd May 2012

A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?
