Problems solved by technology

[0005] However, the inventor found in the research that under the existing sorting method, in order to make the product information rank higher, some suppliers continuously update the release time by resending the product information several times a day
A large amount of resending information every day not only consumes a lot of technical resources such as bandwidth, databases and servers, but also causes some suppliers to viciously compete in the sorting method based on release time, which ultimately reduces user experience.

Embodiment 1

[0022] see figure 1 , which is a flowchart of an embodiment of a method for sorting query results in the present application, the method includes the following steps:

[0023] Step 101: Collect the features of the query results according to the extracted query results that meet the query conditions of the user. The features of the query results include: a quality factor indicating the quality of the query results, an activity factor indicating the activity of the query result supplier, Indicate any one or any combination of the industry factor of the industry in which the query result supplier is located, the information click conversion rate and the information feedback conversion rate of the query result supplier;

[0024] Wherein, the quality factor of the information quality of the collection query result includes: the quality index of the query result according to the statistics of the database information, the quality index of the query result includes any one or any of ...

Embodiment 2

[0049] Different from the above-mentioned embodiments, in addition to using any one or any combination of quality factors, activity factors, information click conversion rates, information feedback conversion rates and industry factors as features for feature fitting, the The timeliness factor is also used as a feature for feature fitting. see figure 2 , which is a flow chart of another embodiment of a query result sorting method of the present application, including the following steps:

[0050] Step 201: According to the extracted query results that meet the user's query conditions, collect the quality factor indicating the quality of the query results, the activity factor indicating the activity of the query result supplier, the industry factor indicating the industry of the query result, and the query result supplier Any one or any combination of information click conversion rate, information feedback conversion rate;

[0051] Since the previous embodiment has collected...

Embodiment 3

[0061] see image 3 , which is an overall structural diagram of an information query system of the present application. Such as image 3 As shown, when the user enters the query keywords into the information query system, the information query extracts the query results that match the query keywords from the database, and first sorts the query results based on the MLR correlation ranking model. In the level, they are arranged according to the feature fitting value, and finally the sorted query results are displayed to the user. Targeted at image 3 In the query system, the following takes feature fitting based on quality factor, activity factor, industry factor, information click conversion rate and information feedback conversion rate as an example to describe in detail the sorting method of query results in this information query system. see Figure 4 , which is a flow chart of another embodiment of a method for sorting query results in this application. Include the fol...

Abstract

The embodiment of the invention discloses a method and device for sorting query results. The method comprises the following steps of: acquiring any one or the combination of any multiple of a quality factor for indicating the quality of the query result, an activity level factor for indicating the activity level of a query result supplier, an industry factor for indicating the industry in which the query result supplier manages as well as the information clicking conversion rate and the information feedback conversion rate of the query result supplier according to the extracted the query results according with query conditions; carrying out feature fitting on the basis of a support vector machine (SVM) regression model by using the acquired contents as features of the query results to obtain feature fitting values of the query results; and sorting on the basis of relevant values of the query results and arraying the feature fitting values of the query results from high to low in the same correlation level. According to the embodiment of the invention, resource consumption can be saved and the experience of the user can be improved.

Description

technical field [0001] The present application relates to the technical fields of communication and computer, in particular to a method and device for sorting query results. Background technique [0002] When users search for information in the information query search engine system, when the user enters the query conditions, the background information query system extracts the query results that meet the user's query conditions from the database, sorts the query results in a certain way and presents them to the user , so that the user can select the information he is satisfied with from the displayed query results arranged in a certain order. [0003] Wherein, when sorting the query results, the information query system usually considers the timeliness of each query result on the basis of relevance. That is, according to the correlation value of each query result, the query results are first classified into different correlation levels, and then sorted according to the cor...
