Google: summary about the March changes in a search

Updates touched the algorithm of ranging on "freshness", search on pictures and video.

Updates touched the algorithm of ranging on "freshness", search on pictures and video:

Autofilling with mathematical characters.
When we process queries, returning prognoses in autofillings, we usually normalize them in accordance with more актуальными prognoses in sew on to the base.  This change plugs in itself a few characters which before were rationed: "+", "-", "*", "/", "^", "(" ")", and "=".

Improvements of treatment of characters for indexation.
We in general to ignore the signs of препинания in queries.  On the basis of analysis of our queries there is a stream, we now began an index following characters of "%" are actively utillized, "$", "\", "@", "#" and "+" ".".  We will continue to index more than characters, use of warrant.

The best wiring for the sound of new of groupments.
News of results on Google, organized in groups which approximately in that history.  We are the скоринговые systems, to define the order of these groups for this query.  It a thin change improves our system of estimation insignificantly, that will result in the improvement of ranging of news of clusters.

Sitelinks of recovery of data.
Sitelinks (Refs.s which appear under some results of search and reference deeper in the proper place) is created partly autonomous process which analyses the structure of site and other information, to define the most proper Refs.s, to rotin users.  We recently renewed information to on sew on autonomous behavior.  These updates take a place often (порядка week).

An improvement of autofilling is rendering-engines, illumination. 
For us the consolidated system and to shorten the amount of server bells, necessary for preparation of autofilling prognoses on Your query.  As a result more effective use of processor and more complete prognosis.

Improved treatment of change of password. 
Our general approach consists in that at changing of password, you will be signed from Your account on all of machines.  This change guarantees that the change of password more consistently signs your аккаунт from a search, in the whole world.

Better than indexation of page of type.
This change promotes plenitude public pages of type in our index from more than two hundred social sites.

User interface for the update of news of Universal.
We renewed the design of New the Universal results, providing more than results from above a cluster, uniting the user interface of treatment of clusters of different size, addition a large font for топ-статьи, addition a picture in a megascopic kind (from the licensed sources), and addition information about an author.

Improvement of results for navigation queries.
A "navigation query" is search, where it looks as an user searches, to pass to the certain web site, for example, [New York Times] or [wikipedia.org] .  While these searches an outage can appear, there are yet problems to service the best results.  For example, that if user actually does not know correct URL?  That to do, if URL do they search, seems, parked domain (without maintenance)?  This change improves the results of such search.

High-quality sites algorithm of recovery of data and freshness of improvements.
As well as many other changes which we do, aspects sew on the high-quality algorithm of sites depends on treatment, that it is done in autonomous behavior and a periodic cycle is placed .  Perfected, that our bases more fresh on the whole.

To live results of League of champions of UEFA and KKHL.
We added living updates of fragments in the results of search in KKHL and Leagues of champions of UEFA, including estimations and graphs.  Now you can find living results of different sporting leagues, including NFL , NBA , NHL  et al.

A function of search is Tennis.
We entered the new function of search in real time, to provide the great number of tennis in overhead part of page results of search.

More relevant results of search of images.
It we utillize a change the melody of signals, CPLD from quality of target page for images.  It does him more probably, that you will find images very актуальны, even if these images on pages which more low quality.

Fresh image prognoses on all of languages. 
We recently rolled out changes on a surface more актуальными prognoses search of images in autofillings in English language.  This improvement extends updates for all of languages.

Safe algorithm of tuning. 
In this month we rolled out a few changes, that our algorithm of SafeSearch.  We renewed our classifier, to do him more clever and more precisely, and we found new methods to do adults rarer to appear, when an user does not search him.

Changes in treatment anchor text. 
In this month we displaced with a classifier, related to the anchor text (a visible text appears in Refs.s).  Our experimental information show that other methods of treatment anchor by great success, so that disconnecting of this component was done by our hammered clean and more steady.

Simplification for an image the Universal code. 
We did some improvements for simplification of our koda for an image Universal and it is better to utillize improvement in our general rating of web also to provide the best results image.

Better than rating of appendixes and user interface on a mobile telephone.
At the search of appendix on your telephone, you will see, rich results with the icons of appendixes, star ratings, prices and load of the buttons, located on well lie down on small screens.  you also will see more актуальной rating of mobile applications on the base of platform of device, for example, Android or IOS.

Improvements in video freshness of Universal.
We improved freshness of video it is better to find out results out-of-date videos and to return new maintenance.

Less than undesirable synonyms.
At a search on Google, we often to expose other terms of search, which can have that sense, that you entered in the field (synonyms) and superficial results of these terms, and also, when it can profit.  In this month we optimum classifier, to prevent unavailing synonyms from inculcated as maintenance in the set of results.

Improved processing of inquiries from both the navigation and local intentions.
Some queries are both local and intentions are a very navigation (directed on a certain web site).  This change is improved by balance of results we show, and also helps to guarantee that you will find a very актуальной navigation results or local results in overhead part of page as necessary on Your query.

Improvements of freshness.
We started the improvements of freshness at the end of the last year, that was very useful, but it costed the considerable resources of computer.  At that time we decided to open out changes only for the news of CPLD traffic.  In this month we took for a ride him on all of queries.

Improvements of treatment for the exposure of quality of site.
We did some improvements in the system a long ago we must find out qualities of site.  This improvement allows to get a large confidence in sew on classifications.

Better than interpretation and use anchor text.
We improved the systems we utillize, to interpret and utillize an anchor phototypograph and to define how the proper given anchors can be for this query and on a site.

Better local results and sources in Google News.
We humiliating signal we must were help people to find content from local country, and we build logic in other signals we utillize.  As a result more актуальных for the local news of Google of results and more than sources of quality.

Humiliating signal, CPLD from rating in press-clastrer.
We humiliating signal, that it already is a not increase of meaningfulness in News of Google. a signal was developed, to help people to find more high quality of the Article on Google News. (Note: In spite of start code, this project has nothing in common with a caffeine, our updates of indexation in 2010).

Less than "family" synonyms.
One of basic signals we will consider for determination of synonyms context.  For example, if a word "lady-cat" often appears next to a term "home animal" and "fluffy", and similarly word "kitten", our algorithms can guess that a "lady-cat" and "Kitten" have identical values.A problem is in that sometimes this method will be to enter "synonyms" which actually are different structures, in a that category.  To continue, for example, dog and «fluffy home animals» - so sometimes a "dog" can be entered wrong, as a synonym of word "cat".  We worked during some time, that proper to discover these "family" synonyms, and our newest systems are more comfortable, renewed, to debugging and upgradable with other systems.

The best exactness synonym and to the productivity.
We did further perfection sew on systems of synonyms, removing the doublets of logic.  In addition, we found methods, more exactly to define the proper synonyms in those cases, when a few candidates are synonym different contexts.

Receipt of tuning of the system.
We improved the systems, which determine terms in queries which must get the proper documents not necessarily.  It will allow to do a result more near to to an original query.

Less aggressive synonyms.
We heard reviews from users, that sometimes our algorithms are too aggressive on including of results of search for other terms.Principal reason often is by a synonym sew on system which will plug in itself results other terms in many cases.  This change is done by our synonym system less aggressive in that, how it plugs in itself the results of other terms of query, putting greater weight upon initial request of user.

Update for the system, leaning against geographical information. 
We have a row of signals which lean against geographical information (analogical information which we are surfaces in Google Earth and Maps).  This change renews some geographical information, we utillize.

Improvements to name a discovery. 
We improved the system for finding out the names, in particular, for a celebrity the names.

Update for personalisation of signals. 
This change testifies updates utillized for personalisation of results of search.

An improvement of image is actuality of search.
We renewed signals, that it is better to promote enough high-quality images are on high-quality target pages.

You will delete out-of-date signal from the signals of site actuality.
We cleaned out-of-date product purposeful signal from the site of understanding of algorithm.

More exact discovery of old pages.
This change is promoted by the level of detection of before out-of-date pages in our index, leaning against more proper signals. As a result, less than out-of-date pages are shown users.

Change in the language of finding out autofilling.
In general, autofilling relies on a display language, to define in what language of predictions, to rotin.  For most languages, we also try to determine the language of query of user on the basis of analysis of scenarios, and this change spreads, that conduct on Chinese (simplified and traditional), Japanese and Korean.End-point is that when users forget to turn off their editors of IME, they however will get English prognoses, if they will begin to enter the English terms.

Improvements in the day of finding out блог / forum.
This change is improved by an algorithm which determines the terms of блог and forum.

More than prediction of autofilling living copying of queries prefixes.
Herein change we copyings partial queries on the fly to get more possibilities for prognoses upon request of user. We utillize synonyms and other possibilities, to get the best general match. Rewrote prefixes can plug in itself a term change of order, term of addition, term of absorption and other great deal.

Extended Refs.s of site on a mobile telephone.
We started our extended Refs.s of site  of function for mobile browsers, providing the best organization and presentation of reference of site in the results of search.

More exact short answers.
We renewed our sources for  short answers have  to rely on information from Freebase .  It promotes exactness and does him it is easy to correct errors.

Migration of Video is the Extended search of rendering-engines.
We migrated some rendering-engines are utillized in video of the extended search our basic infrastructure of search.

+1 Buttons in search of greater number of countries and areas.
In this month we are internationalizations +1 button on a page with the results of search on other languages and domains. +1 Button of search allows to be easily exchanged recommendations with the world on the right of results of search.  As we already talked in our primary блоге, beauty +1 S is their actuality, you take a title on recommendation (because they come from from people which are important for you), at the right time (when you actually searches information on this topic ) and in a necessary format (results of search).

Local result user interface of update on a plane-table.
We renewed the user interface of local results on pills, to do them more compact and it is easy to check.
