[0004] However, in the above method, when analyzing the user's interest, all the keywords obtained will be used as the user's interest. If the input text is "automotive mold", both "automobile" and "mold" will be used as the user's interest. However, the user's interest is focused on "molds" rather than "cars", so that users' interests and hot spots of concern cannot be accurately determined through user search keywords

Embodiment 1

[0024] figure 1 It is a flowchart of a method for obtaining search keywords provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of obtaining search keywords. The method can be executed by a device for obtaining search keywords, and specifically includes the following steps :

[0025] Step 110, counting specific relevant keywords and specific irrelevant keywords in the target field.

[0026] Among them, the target field can be a field determined by studying a certain interest or demand of the user, for example, the target field can be the automobile field determined by studying whether the user has the willingness to buy a car, or the tourism field determined by studying whether the user has the willingness to travel Wait.

[0027] Specific related keywords are keywords related to a certain interest or demand of the user. Specific irrelevant keywords are keywords that have nothing to do with the user's interests or needs. Among t...

Embodiment 2

[0046] figure 2 It is a flow chart of a method for obtaining search keywords provided by Embodiment 2 of the present invention. This embodiment of the present invention is further optimized on the basis of Embodiment 1. see figure 2 , the method provided in this embodiment specifically includes the following steps:

[0047] Step 210: Obtain the text to be analyzed according to the search URL composition rules corresponding to the search engine.

[0048] The text to be analyzed entered by the user in the search engine will be included in the uniform resource locator (UniformResource Locator, URL), then the search URL of the search engine is analyzed to obtain the composition rules of the search URL corresponding to the search engine, and then the text to be analyzed can be obtained. text.

[0049] Preferably, step 210 includes the following steps:

[0050] Step 211, using the regular expression corresponding to the search engine to obtain the character string containing t...

Abstract

The invention discloses a method for acquiring search keywords. The method includes: making statistics about specific relevant keywords and specific irrelevant keywords in a target domain; performing word segmentation on to-be-analyzed texts acquired to acquire candidate keywords; matching the candidate keywords with the specific irrelevant keywords; if the candidate keywords fail in matching, calculating similarity of word vectors of the candidate relevant keywords and word vectors of the specific relevant keywords in the target domain; if the similarity is greater than a preset threshold, outputting the specific relevant keywords in the target domain as the keywords of the to-be-analyzed tests. With the method, the keywords relevant to certain interests or requirements of users can be accurately output according to the to-be-analyzed tests input by the users can be realized, the specific relevant keywords in the target domain, higher in similarity with the candidate keywords are output as the keywords of the to-be-analyzed tests, and the search keywords are enriched for the users.

Description

technical field [0001] The embodiments of the present invention relate to the field of information processing technologies, and in particular, to a method and device for acquiring search keywords. Background technique [0002] With the rapid development of the Internet, people gradually rely on the results of Internet search as the entrance to obtain information. Through the analysis of the user's search keywords, the user's interests and hot spots can be obtained, and the user's own preferences and potential related items of the business can be excavated. [0003] Most of the current search keyword acquisition methods are to directly extract a preset number of keywords from the text input in the search box as search keywords, such as segmenting the input text and sorting the candidate keywords obtained after word segmentation , extracting a preset number of candidate keywords as the user's search keywords. Specifically, if the user types "automobile mold" or "automobile m...
