Example Embodiment

[0072] Example 1

[0073] refer to figure 1 , showing a flowchart of steps of a method for determining a recommended object provided by an embodiment of the present disclosure, such as figure 1 As shown, the method for determining the recommended object may specifically include the following steps:

[0074] Step 101: Acquire target session information and at least one session information associated with the target session information.

[0075] The embodiments of the present disclosure can be applied to a scenario where an object that the user may click next is determined, and the object is recommended to the user.

[0076] The target session information refers to the session information formed by the target user clicking on an object (such as a business, an item, etc.) within a current period of time.

[0077] The at least one session information refers to session information of a historical period associated with the target session information.

[0078] Understandably, at...

[0104] Embodiment 2

[0105] refer to figure 2 , showing a flow chart of the steps of another method for determining a recommended object provided by an embodiment of the present disclosure, such as figure 2 As shown, the method for determining the recommended object may specifically include the following steps:

[0106] Step 201: Acquire current target session information of the target user.

[0107] The embodiments of the present disclosure can be applied to a scenario where an object that the user may click next is determined, and the object is recommended to the user.

[0108] The target session information refers to the session information formed by the target user clicking on an object (such as a business, an item, etc.) within a current period of time.

[0109]When the next click behavior of the target user needs to be predicted, the current target session information of the target user can be obtained, and then step 202 is performed.

[0110] Step 202: Determine ...

[0166] Embodiment 3

[0167] refer to image 3 , which shows a schematic structural diagram of a device for determining a recommended object provided by an embodiment of the present disclosure, such as image 3 As shown, the device for determining the recommended object may specifically include the following modules:

[0168] a session information acquisition module 310, configured to acquire target session information and at least one session information associated with the target session information;

[0169] a global information determination module 320, configured to determine global information and local information corresponding to the target session information according to the representation vectors of all objects in the target session information;

[0170] a session impact acquiring module 330, configured to acquire session impact information of the at least one session information on the target session information;

[0171] The recommended object determination mod...

Abstract

The embodiment of the invention provides a recommendation object determination method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring targetsession information and at least one piece of session information associated with the target session information; determining global information and local information corresponding to the target session information according to the representation vectors of all the objects in the target session information; obtaining session influence information of the at least one piece of session information onthe target session information; and determining a recommendation object corresponding to the target session information according to the global information, the local information and the session influence information. The method of the invention can improve the recommendation accuracy.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of session information processing, and in particular to a method, device, electronic device, and storage medium for determining a recommended object. Background technique [0002] In the era of big data, recommendation systems are playing an increasingly important role, which can filter out information that users are interested in to alleviate the problem of information overload in various application fields. Conventional recommendation methods are usually static, based on explicit user identification (such as user gender, age attributes, user history, etc.), while user preferences change dynamically over time, and user attribute identification is in a certain may not be available in some application domains. [0003] In order to solve the above problems, a session-based sequence recommendation task is proposed. A session can be understood as a transaction sequence containing many ite...
