Embodiment Construction

[0034] In a specific area of ​​the information search result page returned by the information search server to the user, several information display positions are provided for displaying display information related to the query word submitted by the user. The information search mechanism provided by the embodiment of the present application, when displaying information for the current search session, simultaneously considers the display position of the display information clicked by the user last time and the number of clicks that have occurred, so as to simultaneously describe the information clicked by the user The distance between the display position and the display position clicked by the previous user and the click propensity decay, thereby overcoming the shortcomings of the existing click model.

[0035] The information search server provided in the embodiment of the present application includes a display information database and a click log.

[0036] The display inform...

Abstract

The invention discloses an information search method and a display information sorting weight value determination method and device. When the information which is displayed on a search result page is searched by an information search server according to a query term, sorting weight values of the information to be displayed are determined according to a display information sorting model and a click log and the sorting of the display information is determined according to the sorting weight values. The display information sorting model is based on the assumption that the probability that a user clicks the display information after viewing the display information depends on the self-display-information and the probability that the user views the display information located at the location I depends on the number of times that the display information located at the locations before the location I is clicked and the location position of the clicked display information and closet to the location I in the locations before the location I. According to the information search method and the display information sorting weight value determination method and device, the influence on the sorting of the position bias can be reduced and the reasonability of the sorting can be improved when the display information is sorted based on the click information.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to an information search method, a method for determining the sorting weight value of displayed information, and a device thereof. Background technique [0002] When the information search server provides users with information search services, while returning the search results according to the query words entered by the users, it will also display a certain amount of information related to the query words in a specific position on the search result page for users to click to view . A user may click some display information at a specific location in a search session (that is, a search result obtained from a search behavior), and the information search server will use logs to record the display and click of these display information. [0003] The user generally clicks according to the relevance of the displayed information, and the click log reflects the user's...
