Embodiment 1

[0071] Please refer to figure 1 , the keyword-based search method described in the embodiment of the present invention specifically includes the following steps:

[0072] Step 11, obtaining first search information input by a user, where the first search information includes a first keyword.

[0073] Step 12, obtaining second search information input by the user, where the second search information includes a second keyword, and the first keyword is different from the second keyword.

[0074] Step 13, when the first search information and the second search information satisfy a predetermined relationship, perform semantic analysis on the first keyword and the second keyword to obtain an analysis result.

[0075] Step 14, according to the analysis result, obtain a third keyword matching the analysis result, the third keyword is different from the first keyword, and the third keyword is different from the second keyword The words are different.

[0076] Step 15, prompting the...

Embodiment 2

[0081] The keyword-based search method described in this embodiment maintains the historical data of keywords input by a certain user when searching, and performs semantic analysis according to the keywords input by the user in the most recent period when performing a search for the user. The analysis result is obtained, and the relevant keyword is obtained according to the analysis result, and the relevant keyword is prompted to the user, so that the user can more easily obtain a more accurate search term. The keyword-based search method described in this embodiment includes the following steps:

[0082] Step 21, obtaining the first keyword input by the user.

[0083] Step 22, start the search based on the first keyword, and obtain a first start time for starting the search based on the first keyword.

[0084] Step 23, obtaining the second keyword input by the user, where the first keyword is different from the second keyword.

[0085] Step 24, start the search based on the...

Embodiment 3

[0093] The difference between this embodiment and Embodiment 2 is that when performing the current search (search based on the second keyword), the search is further combined with the third keyword obtained through semantic analysis and matching processing, so that the search result is more accurate. Match user search intent. The keyword-based search method described in this embodiment includes the following steps:

[0094] Step 31, obtaining the first keyword input by the user.

[0095] Step 32, start the search based on the first keyword, and obtain a first start time for starting the search based on the first keyword.

[0096] Step 33, obtaining the second keyword input by the user, the first keyword being different from the second keyword.

[0097] Step 34, start the search based on the second keyword, and obtain a second start time for starting the search based on the second keyword.

[0098] The first and second starting times here may specifically be the time when th...

Abstract

The invention provides a keyword-based search method, a keyword-based search device and a server. The keyword-based search method comprises the following steps of: acquiring first search information input by a user; acquiring second search information input by the user; when the first search information and the second search information meet a preset relation, performing semantic analysis on a first keyword and a second keyword, so as to acquire analysis results; acquiring a third keyword matched with the analysis results according to the analysis results; and prompting the third keyword or searching combined with the third keyword, and displaying a search result. By using the keyword-based search method and the keyword-based search device, the user can search the keywords conveniently.

Description

technical field [0001] The invention relates to the field of search technology, in particular to a keyword-based search method, search device and server. Background technique [0002] Various search engines in the prior art usually search based on keywords input by users. In order to reduce the burden on users, some search engines can prompt related keywords based on the keywords entered by users, and users can directly select them without re-entering them. However, the current implementation of prompting related keywords usually recommends optional keyword combinations to users based on the query frequencies of related keywords input by all users in the past. This recommendation method, which depends on the query frequency of all users, sometimes cannot well meet the needs of users. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a keyword-based search method, search device and server to fac...
