For comprehensiveness, most of us turn to traditional news outlets, such as those aggregated by Google News. But Google News relies on algorithms to rank stories, and while the algorithms are pretty good, they aren’t necessarily as fast as the news.
That’s why Yahoo BOSS engineer Vik Singh created TweetNews. TweetNews takes Yahoo’s news results and compares them to emerging topics on Twitter, in effect using what’s most popular on Twitter as an index for determining the importance of news stories.
In other words, TweetNews uses Twitter to rank stories that are so new they may not have enough inbound links for algorithm-based ranking systems to prioritize them.
The result is a search engine mashup that tracks breaking news stories ranked by Twitter search results, offering faster updates, better relevance and more in-depth coverage than either source by itself.
So really do not understand it, but if I substitute my search in this link, it works.
