Description

Internet Video Search System

technical field

The invention relates to a system in the field of network application technology, in particular to a network video search system.

Background technique

With the continuous development of Internet technology, the current network video has become a relatively wide medium in the transmission of information. Mainstream video operation websites emerge in endlessly, and the well-known ones in China include Youku, Tudou and so on. The well-known ones abroad include youtube and so on. Some comprehensive portal websites also have their own video services to broadcast news and other media content. In addition to providing users with search functions, search engines are essentially a tool for statistical analysis of data information. The early Internet was dominated by text information, and now online video has become the main information carrier. Search engines need to have corresponding statistical analysis methods for video media.

After searching the existing literature, it is found that the 2007 Beijing Jiaotong University master's degree thesis "Design and Implementation of Search Engine Based on Network Video Service", the classification number is TP393.09, this paper mainly discusses the search engine system based on network video service , its system architecture mainly includes three modules: information capture module, information index module, and information retrieval module. stored in the database. The information retrieval module mainly reads the attribute information of the video from the database, and after Chinese word processing, uses Lucene to generate index files. The information retrieval module includes a user interface and an indexer. The user interface mainly accepts the keywords input by the user and returns the search results to the user. The indexer mainly retrieves the index files according to the keywords of the user and sorts them according to certain requirements. Although this paper discusses the method of implementing a network video search engine, the search system designed by it provides relatively single functions, can only search for network videos, and the search takes a long time, cannot provide multi-level search interfaces, and does not have network Video hot word analysis function, user interest management function and network video address detection function.
