Problems solved by technology

[0003] However, hot search words in the prior art are usually the result of manual intervention. With the demand for hot search words under each category, if the intervention of hot search words is performed by manual editors, the workload will increase significantly, and if If the people who edit the hot search terms are less sensitive to hot events, the accuracy of the hot search terms will be lower

Embodiment 1

[0090] Determine the hot search words by querying the search term (query) library, such as figure 2 As shown, the process of determining hot search terms may include the following steps:

[0091] Step 201: use the extracted core words to query the query database, and determine the search words that the extracted core words match in the query database. The query library includes correspondences between search words and core words extracted from the search words, and the search words in the query library are search words whose search effects meet preset requirements.

[0092] In order to facilitate understanding, the establishment of the query library is first explained: analyze the previous search logs to obtain search words whose search effect meets the preset requirements, such as search words whose search frequency is greater than the preset threshold; extract core words from the search words , the core word can be extracted in the same way as described in step 103 from ne...

Embodiment 2

[0109] The extracted core words and their combinations are used as search words for page search, and the hot search words are determined according to the search results. Such as image 3 As shown, the process of determining hot search terms may include the following steps:

[0110] Step 301: Use each core word and its combination as a search word to perform a page search.

[0111] Step 302: According to the search results, determine the search words satisfying the preset search effect as hot search words.

Abstract

The invention provides a method and a system for generating a hot-searching word, wherein the method comprises the following steps of: clustering grasped news pages to form various news clusters; determining a hot spot news cluster in the news clusters; extracting core words from the news page of the hot spot news cluster; and determining the hot-searching word according to the searching effect corresponding to the extracted core words, wherein the hot-searching word covers one or more of the extracted core words. The invention can automatically generate the hot-searching word without manual intervention, reduces the workload of labor, does not depend on the sensitivity degree of an editor on a hot issue any more, and improves the accuracy of the hot-searching word.

Description

【Technical field】 [0001] The present invention relates to the technical field of information processing, in particular to a method and system for generating hot search words. 【Background technique】 [0002] With the continuous development of Internet technology and the continuous expansion of information, people's demand for network information is getting higher and higher. In order to adapt to this change, many new technologies have emerged in the field of network search. Among them, providing search suggestions for users through hot search words is one of the new technologies. Users can learn about recent hot events through hot search words, and further browse to obtain relevant information about hot events. [0003] However, hot search words in the prior art are usually the result of manual intervention. With the demand for hot search words under each category, if the intervention of hot search words is performed by manual editors, the workload will increase significantly...
