Google Patent Trustrank : Technology  

Sunday, September 06, 2009

Google is filing a patent for TrustRank, a technology that aims to sort Google news results by quality rather than simply by "date" and "relevance" to search terms.

Google database will be built by continually monitoring the number of stories from all news sources, along with average story length, number with bylines, and number of the bureaux cited, along with how long they have been in business, the number of staff a news source employs, the volume of internet traffic to its website and the number of countries accessing the site.

Google will take all these parameters, weight them according to formulae it is constructing, and distil them down to create a single value. This number will then be used to rank the results of any news search.

There are some interesting and valid points mentioned in the Google Research paper on Combating Web Spam with TrustRank.
