Google in-house staff talk about the rankings on the Google

May, Udi Manber introduced our search quality group, this group is mainly responsible for the ranking of search results. He introduced various teams within the group, including the core position, the international search, user interfaces, evaluation, networking, and some other junk group. this article, we introduce the core under the top panel.
As a responsible company in the Google rankings related to staff, I work in this field for nearly 18 years, in 1990, when new graduates to enter into this number of occupations. In the academic community, the search areas will be called the information search (referred to as IR). Stayed here for 10 years, I in 2000, joined the Google, and work up to now. Google ranking is actually a complex algorithm, it finds the user access to the most relevant results, and presented to the user. Every day we are dealing with a flood of inquiries related to the page with as many as 1 trillion. The algorithm is to be submitted to Google for any search services, while the site search is one of the most used one, and most well-known one. Ranking algorithm has been widely made use of the same - and extends through the changes in many other services, including pictures, news, YouTube, maps, product search, bibliographic search, and other.
I have come into contact with a question regarding Google ranking up question is "How do you do?", Of course, which is useful in our multi-factor to determine how the ranking system is perfect and the United States, but will be discussed further later . With regard to Google's ranking, I would like to introduce is:
1) The best regional search results to serve the world
2) Keep it simple
3) No human intervention
The first one is obvious. From our search of a professional spirit, we of course want to make every effort to enable users to obtain the most relevant results. We call this the principle of "no drop any of the search." When we give any country in any language search feedback is not very reasonable results (caused by the development of search engines is definitely not an overnight problem can be resolved) - we are constantly improve them, we have this As technological innovations continue to forward momentum.
The second principle, then it seems obvious. Basically all of the system architecture designers hope that the simplicity of the system design for a search engine, we have a wide range of search request, must be based on feedback from different types of languages relevant results, encountered a more difficult question is In the face of ever-increasing search request, the more and more problems and doubts had begun to enter into our field of vision. We are working hard to make the system more simple, but this by no means implies that the cost of the expense of search quality, this is a constant effort to move forward, but also a valuable activity. We are every week in the ranking changes of about 10 times, while simplicity is our thinking when making these changes up to a question. Our engineers are very clear why a page's ranking for a keyword is ranked somewhere. The whole systematic evidence-based system that can enable us to conduct faster innovation, and we have certainly been achieved. "Simple and efficient" is a very important principle.
We always encounter such problems never-ending, "Google is in the manual editing of the search results? 'On this point, I think through our third principle to explain: There is no manual intervention areas. In our It seems that site is artificially constructed, and as the creator of all kinds of manual pages and page links.
Our algorithm is based on some of these artificial aspects of efforts. The final search results ranking is based upon the algorithm to calculate various types of summary scores, and these constitute an integral part of the score, including social networking site, which are by no means are we human intervention. We believe that the right of any individual subjective judgments are more subjective, and our algorithm massive site site encoding information and related links to be filtered, which in practice than any man-made subjective judgments is more reasonable.
Another intervention in the search results we are opposed to the workers because there were problems in some of the search request sometimes just excited that our ranking algorithm in some of the innovations. Improvements to the basic algorithm not only improves the search, but also led to the whole issue of relevant search updates, while The same is true for other languages. Need to add a point, Google some of the recommended site, a clear regulatory policy requirements, and we for any violation of these principles and norms of disciplinary website. (For example, law-related requirements, information on the health effects on children, viruses, malicious software, etc. etc.)
We will specifically discuss the follow-ranking technical details related to the point we are trying to say is that we are the search results than ever before to improve the fairness, Google will be in the field of information retrieval for all mankind to contribute to making progress.
