I’ve been doing research on Google’s social Q&A sites codenamed Confucius which are in more than 68 countries and multiple languages, but little known in the US. What I’ve seen includes some tantalizing hints about Google Plus, a description of how content submitted to Google Plus might be ranked in Google Web search, and a possible advertising model for Google Plus that was detailed in a Best Paper nominee at the World Wide Web Conference in North Carolina last year.
I started looking at Confucius a week ago, when I published the post, How Google Might Rank User Generated Web Content in Google & and Other Social Networks. My post describes a ranking signal for user generated content in Web search results, derived from a social network user’s perceived authority on different subjects and the quality of their contributions in interactions on the network, These combined scores might be used as a ranking signal in web search results for the content that user creates. The patent filing was published at the World Intellectual Property Organization website rather than the US patent office website, and the authors of the patent were from Google China, including Edward Y. Chang, the head of Research at Google China, seen in the profile page below:
