Disputes caused by the keyword system
The number of web pages on the Internet is already countless. Users want to find a certain piece of information by browsing the web. It is tantamount to finding a needle in a haystack. The emergence of online search engines such as Yahoo!, Infoseek, and Excite provides users with positioning and navigation tools for online navigation. Nowadays, people cannot search for information online without the help of search engines. There are many types of search engines and there are many search methods, and keyword search is one of the important ones.
When it comes to keyword retrieval, we should also start with "meta tags". There is a software parameter in the Hypertext Markup Language (HTML) of the World Wide Web called "meta-tag", which was originally embedded in the source code of the web page by web designers to record information about the web page owner, copyright statement and web page. Keywords and other information. Meta tags are not necessary for the normal operation of web pages, but with the development of search engine keyword retrieval, more and more web designers generally adopt meta tag design. Famous online search engines such as Yahoo!, lnfoseek, and Excite all have keyword retrieval functions. That is, after a user types in a keyword they want to find, the search engine will display the Keywords in the meta tag of the source code of the web page. search result. If the web page does not set keywords, the search engine's encoder has to either read the entire web page or scan a certain amount of the web page's text content (such as the first 200 words). This not only has a high error rate, but also is slow. In comparison, keyword search has more advantages. Under normal circumstances, search engines also set up links from the query results to the corresponding websites. As long as the user clicks on any item listed in the query results, the corresponding website can be accessed.
Relevant people predict that the keyword system will become more and more commonly used as an online identification system like the domain name system, and may even replace the domain name system and become the most popular online identification system. The most important query and identification system. When using the domain name system, users who want to visit a website have to record the address of the website and then type the address into the address bar of the browser. However, using the keyword system, users do not even need to record the website address. They only need to type a certain keyword in the search engine to find the website they need.stand. However, at the current stage, the keyword system still has many problems and limitations. For example, many keywords are set as common nouns such as "cars", "books", and "baseball". Although this illustrates the category of the website, it does not play a role in identifying a specific website. For another example, although companies in the United States, the United Kingdom, Germany, Italy, and Switzerland have registered the domain name "telecom" under different top-level domain names, search engines can only find part of them. This shows that current search engine searches The scope and search capabilities are limited, and if used as a primary identification system, it will hinder some companies from promoting and conducting business activities on the Internet.
