However, the artificially pre-labeled central word extraction method is only suitable for a very small number of search keywords. With the common use of search engines, the corresponding search keywords surge, and the manual pre-labeled central word extraction method cannot meet the huge order of magnitude. search keyword extraction requirements
On the one hand, the method of manually labeling and extracting the central words cannot automatically extract the central words. At the same time, it takes more manpower and time to complete the extraction of the corresponding central words, and the extraction efficiency is too low; The subjective evaluation of the same central word is different, so the labeling of the same central word is also different, which may lead to a large deviation between the extracted central word and the real search target of the actual user

The invention provides a method and device for determining a search suggestion based on central words. The method comprises following steps: obtaining the search keywords input by a user of a terminal device; extracting the central words corresponding to the search keywords; and determining a search suggestion recommended to the user according to the central words, wherein the search suggestion is associated with the search keywords. According to the scheme of the invention, the central words corresponding to the search keywords are extracted through a machine learning algorithm; the central words are automatically extracted; the central words of a great number of search keywords can be accurately extracted through a standardized and objective mode; the manpower and the time cost for extracting the central words are greatly saved; moreover, classified training is carried out in the central word extraction process through the machine learning algorithm; the purpose of extracting the central words of a great number of search keywords efficiently and accurately is realized; the search keywords most conforming to the interest of the user are recommended to the user according to the extracted central words; the user is helped to search the demanded search result rapidly and accurately; and the search experience of the user is improved.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular, the present invention relates to a method and device for determining a search suggestion based on a central word. Background technique [0002] With the rapid development of the network, the Internet can provide solutions or related solutions to almost all existing daily problems, providing great convenience for people's life and work. When a user uses a web search engine to make a related query, the existing web search engine can provide the user with search suggestions related to the search keyword according to the search keyword entered by the user. The existing method of obtaining search suggestions related to the search keywords is to extract the core words of the search keywords through manual pre-labeling, and recommend the most likely interest to the user based on the extracted core words. search keyword. However, the artificially pre-labeled central word extrac...
