What is "vertical media"

As a kind of vertical media, the definition of vertical website is summarized by the landlord himself. \x0d\x0d\ 1) Vertical website: \ x0d \ Unlike the first generation of large-scale comprehensive horizontal websites (also known as comprehensive websites), vertical websites focus on certain specific fields or specific needs, providing all in-depth information and related services about the fields or needs. As a new highlight of the Internet, vertical websites are attracting more and more attention. While more and more networks attract people's attention, netizens have gradually stepped out of the primary stage of fashion and curiosity, constantly looking for practicality, practicality and benefits on the Internet. \x0d\(2) Vertical search: \x0d\ Vertical search has obvious significance to consumers. With the rapid growth of Internet users and online content, the transition from general information sources to special information sources is natural. Using Baidu and Google to find a used car is like looking for a grain of sand in a glass vase. Is there any way to get to the point? This depends on the emerging vertical search. There is a clear saying in the search field: a user cannot describe what he is looking for unless he is shown what he is looking for. This process is a bit like finding an object, and "taking chances" is the biggest feature of users' search behavior. Vertical search engines help users improve their "luck". \x0d\ Vertical search is a professional search engine for a certain industry, which is a subdivision and extension of search engines. It is the integration of some special information in the web library, which extracts the required data through the direction field, processes it, and then returns it to the user in some form. \x0d\ The biggest difference between a vertical search engine and an ordinary web search engine is that it extracts structured information from web information, that is, it extracts unstructured data of web pages into specific structured information data, just like web search takes web pages as the smallest unit, web page block analysis based on vision takes web page block as the smallest unit, and vertical search takes structured data as the smallest unit. These data are then stored in a database for further processing, such as deduplication, classification, etc. Finally, word segmentation and indexing can meet the needs of users through search. \x0d\ During the whole process, data is extracted from unstructured data and turned into structured data, which is returned to users in an unstructured and structured way after deep processing. \x0d\ Vertical search engine has many applications, such as enterprise database search, supply and demand information search engine, shopping search, real estate search, talent search, map search, mp3 search and picture search? Almost all kinds of information from all walks of life can be further refined into various vertical search engines. \x0d\ For example, it will be easier to understand, such as shopping search engines. The overall process is roughly as follows: after crawling the webpage, extract the product information from the webpage, and extract the product name, price and introduction. You can even further subdivide the notebook configuration file into "brand, model, CPU, memory, hard disk, display,?" Then the information is cleaned, copied, classified, analyzed and compared, and data mining is carried out. Finally, it provides user search through word segmentation index and market report through analysis and mining. \x0d\ Vertical search engines generally need the following technologies \x0d\ 1. Spider \x0d\ 2. Web page structured information extraction technology or metadata collection technology \ x0d \ 3. Word segmentation, index \ x0d \ 4. Other information processing technologies \ x0d \ The technical evaluation of vertical search engines should be judged from the following points \ Without professionalism and superb technology, it is impossible. Industry portal has industry advantages, but it has no technical advantages. Don't imagine that all the techniques of vertical search can be done by recruiting a few people. As a product that needs continuous improvement and operation, rather than a project, the mastery of technology is one of the important factors for the success of vertical search. \x0d\ Three characteristics of vertical search engine: \x0d\ 1. The data captured by the vertical search engine comes from the industry sites concerned by the vertical search engine: \x0d\2. The data crawled by vertical search engines tend to be structured data and metadata: \x0d\3. The search behavior of vertical search engine is a structured search based on structured data and metadata;
