Problems solved by technology

[0013] Moreover, the above prior art cannot consider the rewritten search items after rewriting as a meaningful whole, and it is possible to think that the combination of important participles is meaningless, or even escaped
[0014] Aiming at the problem that the processing result of the search item input by the user is not perfect in the above-mentioned prior art, resulting in inaccurate search results, no effective solution has been proposed yet

Embodiment 1

[0030] According to an embodiment of the present invention, a method embodiment of a search engine-based search request processing method is provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be performed on a computer such as a set of computer-executable instructions system, and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0031] The method embodiment provided in Embodiment 1 of the present application may be executed in a computer terminal, a mobile terminal, or a similar user computing device. Take running on a computer terminal as an example, figure 1 It is a hardware structural block diagram of a computer terminal 10 and a background search server 30 running a search engine-based search request processing method according to an embodiment of the present invention. Such as figure 1 As shown, t...

Embodiment approach

[0054] Step S241, read the historical search log, and obtain the historical search item set and the search behavior information of each historical search item in the historical search item set within a predetermined time period.

[0055] combine image 3 It can be seen that the step S241 realizes the sample selection process. can be saved in figure 1 The historical search log session in the shown memory 104 refers to the collection of a series of actions that the user continuously makes in the interval of a predetermined time period (each entry record in the historical search log session usually includes: search user cookie, user usage The search behavior information of the search engine, the time when the search behavior was generated, the location where the search behavior was generated, and the search item corresponding to the search behavior), where a series of actions include the entered historical search items and the search behavior information performed on each histor...

Embodiment 2

[0114] According to an embodiment of the present invention, a device for implementing the foregoing method embodiment is also provided. Figure 4 It is a schematic diagram of an apparatus for processing a search request based on a search engine according to Embodiment 2 of the present invention. The devices provided in the above embodiments of the present application can run on the online game client.

[0115] Such as Figure 4 As shown, the device may include: a receiving module 40 , an acquiring module 42 , a model building module 44 , a checking module 46 and a generating module 48 .

[0116] Wherein, the receiving module 40 is used to receive the current search item input by the user; the acquisition module 42 is used to select the search item used by the user from the historical search log, and obtain at least one candidate search item corresponding to the current search item; the model building module 44. It is used to conduct offline training by using the historical s...

Abstract

The invention discloses a processing method and device of a search request on the basis of a search engine. The processing method of the search request on the basis of the search engine comprises the following steps: receiving a current search term input by a user; selecting the search terms used by the user from a historical search log, and obtaining at least one candidate search term corresponding to the current search term; taking a historical search term set and search behavior information in the historical search log as training samples to carry out off-line training, and establishing a prediction model of user behaviors; using the prediction model to carry out correlation checkout of the candidate search terms and the user behaviors on the candidate search terms corresponding to the current search term; and according to the correlation checkout, taking the candidate search terms which meet a set condition as recommended search terms corresponding to the current search term, and generating a recommended search term set corresponding to the current search term. The technical problem of inaccurate search results can be solved.

Description

technical field [0001] The invention relates to the field of computer internet, in particular, to a method and device for processing search requests based on search engines. Background technique [0002] In e-commerce search, in order to search for the products they need as quickly as possible, the user may enter a very detailed search term (query) and express the demand by constructing multiple word segmentation (term) combinations. However, for commercial search engines, the way of recall generally considers that the multiple word segmentations input by the user are in an "AND" relationship, and it is easy to have no or few results. In response to this situation, the most common way is to rewrite the search terms entered by the user through the search term omission technology to recall more products that meet the user's intention. [0003] Search item omission is to delete some word segmentation in the search item through the search item transformation technology, so as t...
