When we usually use search engines, we usually enter a word to search. For example, if we want to travel to the south, we usually enter the names of famous tourist attractions, such as Kenting Park, Xiziwan, Sichongxi, etc. To search for places to go, these words we commonly use to search are called search keywords. Few people enter a complete sentence to search.
Therefore, many SEOs study what kind of words are often used by online viewers to search, and then optimize the website based on the target keywords. Another thing that SEOs must do when optimizing the website is, It is to study a web page, including web page title, web page content description, web page paragraph organization, keyword density analysis, etc. This work is to arrange the content of a web page in a planned way to cater to the habits and friendliness of search engines.
When it comes to writing the title and content of web pages, there is one homework that must be passed in SEO website optimization. That is, when arranging and planning content, you must understand the word segmentation technology of major search engines. Simply put, it means that the search engine will When analyzing the content of an article, how do you extract keywords? How do you identify what words are related to this article? So SEO website optimization begins with: Google, Live Search, Yahoo! Qimo...etc. The road to exploration of major search engine word segmentation technologies.
According to foreign media reports, although there have been many natural language search engines challenging Google in the United States, Google is not very interested in them. Google's head of research and development recently said that online browsers are too lazy and they are not willing to enter a complete sentence. Google is more concerned about natural language search technology at the phrase level.
The person who made the above statement was Peter Norvig, who is responsible for research and development at Google. Norvig commented on the fact that some search engines allow users to enter entire sentences. "We don't think it's progress to type a sentence into a search box instead of a keyword," he said. For example, if he types "Where is the capital of France?", the results he gets may not be more ideal than if he types "the capital of France".
However, Novig also said that Google believes that natural language technology still has a certain value in "translating" keywords into people's common concepts. He gave an example: "New York" and "York" are different, but "Vegas" and "Las Vegas" have the same meaning, and "Jersey" and "New Jersey" It may be the same, it may be different. This is the natural language technology that Google focuses on. They focus more on words and phrases rather than analyzing the entire sentence entered by the user.
Norvig said that for Google, getting more accurate results is more important than changing the user interface.
Prior to this, Ask.com, the fourth largest search engine in the United States, had launched natural language search technology, but it only decomposed sentences into keywords. The search results were similar to the keyword search mode. Because the intelligence was inferior to Google, Ask.com's Natural language search results are not as good as Google's keyword search results. Later, Ask.com stopped providing sentence search services.
From the above official statement of Google, we can know that the search engine segments and compares the content of a sentence to obtain the content of a web page. Since English and Chinese have different grammars, including people’s idioms, Different, so the search results obtained by Chinese search engines and English search engines are different due to different word segmentation technologies. Here you can use a keyword to experiment on Yahoo and Google respectively. To a large extent, search engines are also constantly Continuously work on the usage habits of online viewers, word segmentation, etc. Only in this way can we ensure that the searched web pages are closest to what online viewers want.
Many new terms are generated in our lives and work every day. By searching for these new terms in different search engines, you can judge which search engine's search results are closer to what we want by looking at the results. Which search engine's word segmentation technology is more advanced. SEO website optimization is a long-term path of exploration. We are willing to share the new technologies we have discovered and the experiences we have summarized with everyone.
