Embodiment 1

[0020] According to an embodiment of the present invention, a method for generating a click model is provided, such as figure 1 As shown, the method includes:

[0021] Step S102 , respectively acquiring historical click information of users in multiple pre-divided geographical areas, and obtaining multiple sets of historical click information corresponding to the multiple geographical areas.

[0022] The user's historical click information is the data information generated by the user through the click behavior. Wherein, the click behavior of the user includes but is not limited to: what document the user clicks on, the time when the click occurs, and the display position of the document at that time. The above-mentioned behaviors can be reflected in the form of data, for example, there is data information reflecting the characteristics of the above-mentioned behaviors in the user's click log. The user's historical click information may be obtained from the user's click log....

Embodiment 2

[0085] According to an embodiment of the present invention, a click model generation device for implementing the above click model generation method is also provided, such as Figure 6 As shown, the device includes: a first acquisition unit 10 , a calculation unit 20 , a clustering unit 30 and a generation unit 40 .

[0086] The first acquiring unit 10 is configured to respectively acquire historical click information of users in multiple pre-divided geographical areas, and obtain multiple sets of historical click information corresponding to the multiple geographical areas.

[0087] The user's historical click information is the data information generated by the user through the click behavior. Wherein, the click behavior of the user includes but is not limited to: what document the user clicks on, the time when the click occurs, and the display position of the document at that time. The above-mentioned behaviors can be reflected in the form of data, for example, there is da...

Embodiment 3

[0112] According to an embodiment of the present invention, a server for implementing the above click model generation method is also provided, such as Figure 7 As shown, the server includes: a processor 702 , a memory 704 and a network interface 706 . The device for processing messages in this embodiment of the present invention may be implemented by a server.

[0113] Wherein the processor 702 can be used to perform the following steps:

[0114] Step S31 , respectively acquiring historical click information of users in multiple pre-divided geographical areas, and obtaining multiple sets of historical click information corresponding to the multiple geographical areas.

[0115] Step S33 , calculating the overlap rate of historical click information among multiple historical click information sets, and the overlap rate is used to represent the proportion of multiple historical click information sets having the same click behavior.

[0116] Step S35, using the overlap rate of...

Abstract

The invention discloses a method and device for generation of click models, wherein the method comprises the steps that historical click information of users in multiple geographic areas which are divided in advance is acquired separately, so that multiple historical click information sets corresponding to the multiple geographic areas are acquired; overlapping ratios of the historical click information among the multiple historical click information sets are calculated; the multiple geographic areas are clustered according to the overlapping ratios of the historical click information among the multiple historical click information sets, so that multiple area classes are obtained; the click models corresponding to the multiple area classes are generated separately and the multiple click models are obtained, wherein the multiple click models are in a one-to-one correspondence relation with the multiple area classes. According to the invention, the technical problem in the prior art that search results obtained through operation of the click models cannot accurately predict click behaviors of the users; and the click behaviors of the users can be predicted accurately based on the click models of the different geographic areas.

Description

technical field [0001] The invention relates to the field of search engines, in particular to a method and device for generating a click model. Background technique [0002] In the Internet field, for websites that provide search services, the search engine system can predict the user's click behavior according to the search terms entered by the user. In this process, the click model plays a vital role. The click model is the modeling of the user's click behavior. According to the user's historical click information, the user's token and behavior are modeled to predict the user's future click behavior and improve the relevance. [0003] However, the inventors have found that due to the geographical differences in users using the Internet, the historical click behaviors of users in different regions are also different, and the existing search engines usually use user behavior to train a click model, thus leading to The search results obtained by running the click model cann...
