Embodiment 1

[0040] figure 1 A flowchart showing a multimedia resource evaluation method according to an embodiment of the present invention. Wherein, the multimedia resource evaluation method is mainly used for evaluating each multimedia resource in the content recommended by the recommendation system to the user. Such as figure 1 As shown, the multimedia resource evaluation method mainly includes the following steps S100, S110, S120 and S130.

[0041] Step S100, acquiring a plurality of user behavior data corresponding to multimedia resources within a predetermined time period.

[0042] For example, the multimedia resource is video. When a user processes a video with terminal devices such as mobile phones, desktop computers, laptops, smart TVs, and set-top boxes, user behavior data corresponding to the video will be generated. In a possible implementation manner, the user behavior data may mainly include a user cookie, a user identifier (ie, a user ID), a user's processing method f...

Embodiment 2

[0063] figure 2 A flowchart showing a multimedia resource evaluation method according to another embodiment of the present invention. figure 2 Winning mark and figure 1 The same steps have the same functions, and detailed descriptions of these steps are omitted for brevity.

[0064] Such as figure 2 as shown, figure 2 The multimedia resource evaluation method shown is the same as figure 1 The main difference between the multimedia resource evaluation methods shown is that, figure 1 Step S130 in can be specifically implemented by executing step S140.

[0065] Step S140, calculating the popularity evaluation score according to the quality evaluation result of the multimedia resource and the recommended content.

[0066] In other words, the result of the popularity evaluation in the above embodiment can be expressed in the form of the popularity evaluation score calculated in this embodiment.

[0067] For example, the popularity evaluation scores of video 1, video 2...

Embodiment 3

[0082] image 3 A structural block diagram of a multimedia resource evaluation device according to an embodiment of the present invention is shown. The multimedia resource evaluation device 10 is mainly used for evaluating multimedia resources in recommended content. Such as image 3 As shown, the multimedia resource evaluation device 10 may mainly include: an acquisition unit 11, configured to acquire a plurality of user behavior data corresponding to the multimedia resource within a predetermined time period; a filtering unit 12, connected to the acquisition unit 11, For filtering a plurality of user behavior data; a quality evaluation unit 13, connected to the filtering unit 12, for evaluating the quality of the multimedia resource according to the filtered user behavior data; and a popularity evaluation unit 14, It is connected with the filtering unit 12 and the quality evaluation unit 13, and is used for evaluating the popularity of the multimedia resource according to ...

Abstract

The invention relates to a multimedia resource assessment method and device, ands aims to assess multimedia resources in recommended contents; the multimedia resource assessment method comprises the following steps: obtaining behavior data of a plurality of users corresponding to the multimedia resources in a preset time period; filtering the behavior data of the plurality of users; accessing the quality of the multimedia resources according to the filtered user behavior data; accessing the heat level of the multimedia resources according to the quality assess result of the multimedia resources and the recommended contents. The multimedia resource assessment method and device can properly consider content self of the commended multimedia resources, thus reducing influences on user experiences by hot spot multimedia resources or headline and screenshot multimedia resources, and improving user experiences.

Description

technical field [0001] The invention relates to the field of multimedia resource processing, in particular to a multimedia resource evaluation method and device. Background technique [0002] Current recommendation systems, such as multimedia resource recommendation systems, mainly use user behavior data to recommend multimedia resources such as videos to users through algorithms such as mainstream CF (Collaborative Filtering, Collaborative Filtering) algorithms and logistic regression algorithms. At present, what is recommended to the user is the multimedia resources that other users like, or the multimedia resources that the user may personally like are recommended according to the user's personal historical behavior (or attribute information). [0003] However, this recommendation technology has less consideration for the content of the recommended multimedia resources, which may cause some socially popular multimedia resources or multimedia resources that rely on titles ...
