Google back in February 2012 had filed a new ranking algorithm patent for Google News--seeks to refine algorithm build on a patent titled "Systems and Methods for Improving the Ranking of News Articles" that Google was issued in 2009.
A Google spokesman said via email, "We file patent applications on a variety of ideas that our employees come up with," he said via email. " Some of those ideas later mature into real products or services some don't. Prospective product announcements should not necessarily be inferred from our patent applications," Computerworld who discovered the patent application writes.
"In February of 2012, a new version of the Google patent was published as a pending application. (A second version was granted in 2012). The third version has the same name as the first version, and it has substantially the same description section as the first version. What's different is the "claims" section," writes Bill Slawski of SEO by the Sea, adding:
The claims section of the new version of the patent starts off with:
Gone are things like the "circulation statistics of the news source," the "number of bureaus associated with the news source," and other things associated with the kind of journalism that's done in print.
The patent application reveals the following potential factors considered by Google's ranking algorithm:
- "Number of articles produced by a news organization during a given time period
- Average length of articles from a news organization
- Importance of coverage from the news organization
- Circulation/syndication of the story
- Size of the staff associated with the news organization
- Number of news bureaus a news organization has
- Number of original named entities used in the story
- Writing style
- Number of non-duplicate articles produced by the news organization
- Breaking news score, which is measured as the ability of the news organization to publish a story soon after the event has occurred," reveals patent application.
