Problems solved by technology

[0004] However, the disadvantages of the prior art are: on the one hand, for the traditional way of obtaining extended words based on a single search device, the number of extended words obtained is relatively small, and the frequency of use is also limited, which cannot better ensure the expansion of words. The timeliness of the results cannot grasp the current search habits of most users as a whole; on the other hand, the APIs provided by each search device for obtaining expanded words are different, and there are many inconveniences in API calls, which are not flexible enough

Abstract

The invention discloses a method and a device for acquiring expansion words of keywords. The method includes: acquiring a target keyword; transmitting an expansion word inquiring request containing the target keyword to at least two search devices through a uniform interface; receiving the search results returned by each search device according to the inquiring request, and obtaining the first-category expansion words of the target keyword according to the search results. By the method, a large amount of expansion words conforming to the search intensions of a user can be obtained, and the defects of inconvenient API calling and inflexibility due to the fact that the APIs, for acquiring expansion words, provided by each search website and e-commerce website are different are overcome.

Description

technical field [0001] Embodiments of the present invention relate to computer data processing technology, and in particular to a method and device for acquiring expanded words of keywords. Background technique [0002] Currently, search devices for searching websites or e-commerce websites (for example, search engines for searching websites) have increasingly powerful functions. After detecting the search sentence entered by the user and extracting one or more keywords in the search sentence, the keywords are usually further expanded or extended to obtain the expanded words of the keywords, such as the extracted keywords It is "computer", and its extended words are "laptop computer", "desktop computer", "computer configuration", and "computer housekeeper". Furthermore, search websites or e-commerce websites can directly provide keywords and their corresponding extended words to users as delivery words, or search for target information based on the obtained keywords and the...
