Association method and system for multi-source video metadata

Abstract

The invention discloses an association method and system for multi-source video metadata, and belongs to the technical field of data processing. The association method comprises the following steps: acquiring videos with different data sources, extracting video metadata of the videos, setting a unique identifier for each video metadata, and associatively storing the video metadata and the unique identifiers thereof and data source identifiers; preprocessing the extracted video metadata, including eliminating duplication, splitting metadata fields and performing format normalization on the metadata fields, wherein the duplication eliminating refers to eliminating duplication of the video metadata with the same data source; and determining the field importance level of the video metadata, and establishing an association relationship among the video metadata according to the field importance level. According to the method and the system, by analyzing the importance of each element (field) of the video metadata, and achieving the establishment of the association relationship of the video metadata with different sources according to importance degrees of different elements, the association accuracy of the multi-source video metadata is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for associating multi-source video metadata. Background technique [0002] With the rapid development of broadband Internet and mobile Internet, the continuous construction of basic network facilities and the continuous improvement of Internet bandwidth capabilities have spawned more and more high-bandwidth Internet applications, especially the application of video content, which has accounted for the entire Internet. About 70% of the total bandwidth, high-definition, ultra-high-definition, 1080P, etc. have become the current mainstream user consumption content, 4K, 8K content has also been born and gradually accepted by users. [0003] The current video application range is very wide. Internet video sites, IPTV (Interactive Network Television), OTT (Over The Top, providing users with various application services through the Internet), Internet TV and ...

AI Technical Summary

Problems solved by technology

However, the video content of PC, Internet TV, and mobile terminal are operated independently of each other. At the same time, the re-editing of the same video content by different Internet video sites also causes large differences in video metadata. Relationships, very low success rate

If the same video metadata from multiple sources cannot be accurately associated together, the final effect that the content aggregation platform can produce will be greatly reduced
