Browser encounters large data: Forecast Next click

Every person in the seabed has had a meal experience of their services are praised, the waiter carefully observe your every action, for you to send the most intimate services: glasses cloth, fruit and so on. Waiting Hall with shoeshine, nail, fruit, melon seeds and other services. If you are a regular customer, you may be offered a more personalized surprise service. In fact, Internet products are already providing the ultimate service of seabed fishing. Seabed fishing is to exert the initiative of employees rely on personal wisdom to predict and communicate user needs and provide sophisticated services, and Internet products by virtue of technology and product innovation constantly to predict user needs, will experience to the extreme.

Amazon: "One click on single" to "Appointment shipping"

Although Amazon's success can be analyzed in terms of patterns, strategies, advertising, prices and many other dimensions, the reason for Amazon's success in the eyes of Silicon Valley, and Bezos, is that it is the ultimate in service. The study of Amazon's most classic book, one-click Single-Bezos and the rise of Amazon, elaborates on this point: "A single button" is Amazon's pursuit of details of the classic action, if a user has ever had a shopping experience in the Amazon, then he browsed the book page will appear "one button next single button", its account, Payments such as information were taken out of the database ahead of time, although this seemingly simple design has become the current trademark match, but it did help Amazon upgrade "a little bit" at that point.

In the midst of fierce competition, it is the cumulative "little" incremental change that has helped Amazon finally beat the crowd. "To be 9 times times larger than your nearest competitor, all you really need to do is to serve 10% better than him." "In 1998, Bezos told The Washington Post. The reason why Amazon can continue to ascend "a little bit" is because it has been thinking about what users are most likely to need.

In recent years, the electrical business technology has been very developed, experience has focused on sinking to the quality of goods, logistics warehousing, after-sales service these "offline" experience, Amazon pioneered the "prediction of the next single" function. Amazon will be based on the user's shopping history, shopping cart content, search history and other data on their preferences analysis, if the determination of consumers are likely to buy a product, Amazon will automatically send the goods to the nearest consumer logistics warehouse, once the consumer orders, The product will be delivered to consumers at the fastest speed.

Browser: Recount solve the problem of Internet speed

Browsers are still the most important tool to access the Internet, although broadband popularity has brought a big boost to the speed of the Internet, but users still feel "not fast enough." Chrome based on the WebKit modified Chromium browser engine through the special V8 JS engine greatly enhance the local rendering efficiency, fast catch IE became the later show, domestic browsers are also trying to achieve "faster" internet. The reason for not being quick is the following:

1, bandwidth resources more abundant, but more equipment, more users and large flow of content, so that bandwidth is still scarce resources. In the late peak and other gold Internet time is more obvious: flat, mobile phone, PC, Internet TV, smart hardware, a variety of devices on the online high-definition video, large-scale online games, real-time synchronization data crowding bandwidth resources.

2, the Web site developers no longer consider bandwidth restrictions but unscrupulous to make the content of the Web page fat. In the era of dial-up Internet, webmasters fully consider the limitations of the technology fully compatible with the "low bandwidth", and now the webmaster are rarely considered in this regard, the Web page has been increasing fertilizer, the average 2012 page size has been for the first time over 1MB.

3, the user's greed led to its ultimate goal is "0 waiting", bottlenecks exist impact speed. In the future, Skynet will be fast, Web Access process will also go through 5 basic steps: 1, Domain name resolution (DNS), 2, request to send 3, Web site processing and response, 4, data loopback, 5, browser rendering, each step more or less need time, and 3 and 4 is easy to become a bottleneck. 4 by the Internet environment decision, 3 is the site itself to determine the speed of access, different sites on the request response time gap is very large. Web server factors (applications, databases, load balancing, files, content, configuration), Topology, server network environment (including CDN) and access concurrency decisions, not every site has the internet giant's resources and technology to eliminate bottlenecks.

To solve the "fast enough" mentality, there are several representatives.

One is local rendering optimization, such as the chrome application of the new browser engine, Sogou takes the lead in the Chrome+ie dual-core mode in compatibility and rendering speed to achieve a balance.

The second is the website data compression and the structure optimization, in the handset browser this technology application is more extensive, uses the browsing experience in exchange for the flow and the time saves.

The third is to speed up the network bandwidth directly, China Telecom, intelligent routers, thunder have bandwidth acceleration services.

The fourth is the Sogou browser guide, Chrome, IE11 and so on have tried to "prefetch" technology.

Prefetching technology: The effect of "one-click" in the browser

IE11 and Chrome to adopt a new protocol, the webmaster to make what content prefetching browser will follow. or prefetch based on a specific label such as "Next page". And their based on the "rules" of the solution, Sogou browser prefetch More is "based on large data statistics" thinking-this is Sogou input method to subvert the violet, Microsoft Input method of the core reasons.

Sogou Browser prefetching technology is divided into two parts: to predict the next demand for users, to get the Web page in advance to local, users click on the link can immediately render display. The forecast of user demand is mainly through three latitude: mining the most popular web page collection through large data in the cloud; Analyzing user characteristics based on user input, browsing, and searching history to analyze the links that are more likely to be clicked at a particular point; From the human-computer interaction behavior to predict the user's mouse action.

Sogou Public Data Display user behavior prediction accuracy of up to 90%, the average can be increased by about 1 time times the Web browsing speed, save 50% of the waiting time, especially in browsing such as news, forums, and other content-like web pages, the effect is better. Prefetching is based on the prefetch goal is "the entire Internet", especially in the current Chinese network conditions, Sogou in this regard is Google and IE, the two browser predators behind. Millet router in order to improve the speed of users, the Miwifi OS access to the Sogou prefetch engine.

In addition to being widely used in browsers, future prefetching techniques can be applied in the following areas:

1, Content recommendation system: prefetching technology is now through the observation of behavior and then speculate on the next step of the user's action and preparation, the future with the development of artificial intelligence, you can put the analysis results directly to the surface, guide the user's next behavior, to recommend content.

2, the speed of search engines: Search engine has been very fast, but it can also be faster, you have not yet searched or just triggered the search will have results appear in front of you. While you are still organizing the next search request statement, search suggestions have been rendered; When you type the first character, the search engine begins to render the result; When you type a search request, the search results appear in front of you, while the results page of the result pages and related search results will be loaded ahead of time.

3, the Electronic Business reservation delivery: Amazon has "forecast shipments", but most of China's electric platform does not have such technical capabilities, the future of prefetching technology will likely be to the vertical development, such as the Electronic Business reservation delivery technology.

4, Offline entity services: With the development of the Internet of Things, in ibeacons, NFC, geo-fencing and other induction technology support, the network can collect users of offline scene data, and forecast its offline behavior, such as travel, shopping, food and so on. Shopping malls supermarkets, tour sites, tourist attractions, transportation and logistics in these areas can be based on the prediction of "prefetching", planning, configuration and preparation of the predecessor.

Finally back to the browser prefetch technology, in the browser many players and difficult to differentiate in the function, who can continue to achieve the ultimate user experience, who can users of the Internet speed to bring even 0.1% of the promotion, who has the opportunity to stand out, the formation of Amazon's "one-click single" Effect.
