Embodiment 1

[0087] refer to figure 1 , shows a flow chart of a method for creating a video index table in Embodiment 1 of the present invention, and the method may specifically include the following steps:

[0088] Step 101, acquire multiple UGC videos uploaded by the client and the video ID of each UGC video.

[0089] UGC video refers to video content generated by users themselves and uploaded to major video sharing websites through Internet technology. UGC videos have a large number of features, and users can search and watch UGC videos uploaded by themselves or other users in video sharing websites. After the user uploads the UGC videos through the client, the server can save these UGC videos, and each UGC video also has a unique video identification (ID). In the embodiment of the present invention, the UGC videos stored in the server can be integrated to provide conditions for the video recommendation process. First, multiple UGC videos uploaded by the client and the video ID of eac...

Embodiment 2

[0114] refer to image 3 , shows a flow chart of a method for creating a video index table in Embodiment 2 of the present invention, and the method may specifically include the following steps:

[0115] Step 301, acquire multiple UGC videos uploaded by the client and the video ID of each UGC video.

[0116] The user uploads UGC videos to the server through the client, and the server can save these UGC videos, wherein each UGC video corresponds to a video ID. First, the server can obtain the UGC videos stored in it and the video IDs of each UGC video, and then perform related processing on them to generate a corresponding video index table.

[0117] Step 302, extract video metadata of each UGC video respectively.

[0118] After the above-mentioned multiple UGC videos are acquired, the video metadata of each UGC video is respectively extracted, and then the multiple UGC videos can be clustered according to the video metadata.

[0119] Step 303, clustering the multiple UGC vid...

Embodiment 3

[0174] refer to Figure 5 , which shows a structural block diagram of an apparatus for creating a video index table in Embodiment 3 of the present invention, and the apparatus may specifically include the following modules:

[0175] Video acquisition module 501, for obtaining the video ID of a plurality of user-generated content UGC videos uploaded by the client and each UGC video;

[0176] Clustering module 502, for clustering the multiple UGC videos, and assigning a video cluster ID for each cluster;

[0177] A sorting module 503, configured to generate description information for the UGC videos in the respective clusters, and sort the description information;

[0178] A generating module 504, configured to generate a UGC video recommendation list using the sorted description information;

[0179] The first creation module 505 is used to create a first-level index table using the video ID and the corresponding video cluster ID;

[0180] The second creating module 506 is c...

Abstract

The invention provides a method and device for creating a video index table and a method and device for recommending video. The problem that recommended video is unordered, is lost and is inaccurate is solved. The method for creating the video index table comprises the steps that a plurality of pieces of UGC video and video IDs of the UGC video are obtained; the UGC video is clustered, and video clustering IDs are distributed to all clusters; description information is generated according to the UGC video in all the clusters and is ordered; a UGC video recommendation list is generated by adopting the ordered description information; a first-stage index table is created by adopting the video IDs and the corresponding video clustering IDs, and a second-stage index table is created by adopting the video clustering IDs and the corresponding UGC video recommendation list. Due to the fact that the description information of the clustered UGC video is included in the recommendation list, the description information is more comprehensive, the problem that certain episodes are lacked is solved, the description information is ordered, and the problem of the chaotic sequence is solved.

Description

technical field [0001] The present invention relates to the field of multimedia technologies, in particular to a method and device for creating a video index table, and a method and device for recommending videos. Background technique [0002] The full name of UGC is User Generated Content, which means user generated content. The concept of UGC first originated in the Internet field, that is, users display their own original content through the Internet platform or provide it to other users for sharing. UGC emerged along with the concept of Web2.0, which advocates personalization as its main feature. UGC is not a specific business, but a new way for users to use the Internet, that is, from the original download-based to download and upload. Friend social network, video sharing network, knowledge sharing network, community, forum, Weibo, etc. are the main application forms of UGC. [0003] UGC video refers to video content generated by users themselves and uploaded to majo...
