Abstract

The invention discloses a distributed index method for video data. The distributed index method for the video data solves the problem that in the prior art, due to the facts that the UGC video data size is very large and data information is huge, a search engine encounters the performance bottleneck. The method comprises the steps that a control node and a plurality of data nodes are set, wherein the control node respectively records the performance information of each data node; the control node receives the video data uploaded by a user side; the control node selects one data node according to the performance information of each data node and controls the selected data node to establish a reverse index file of the video data. According to the technical scheme, after the control node receives the video data uploaded by the user side, the data nodes for establishing the reverse index file are selected according to the performance information of each data node, the distributed index of the video data is achieved under the control of the control nodes, and the accuracy rate of enquiry and the index efficiency are improved.

Description

technical field [0001] The invention relates to information retrieval technology, in particular to a distributed indexing method and a distributed indexing system for video data. Background technique [0002] Indexing technology is one of the core technologies of search engines. The quality of indexing technology directly affects the accuracy rate of search engines and the response speed to users. [0003] However, there is a problem worthy of attention in practical applications: as the number of indexed files increases, the indexing time increases linearly, causing the process of indexing to affect the search experience; in search engine applications, when the number of indexed files reaches a certain level , the search engine encounters a performance bottleneck. [0004] At present, video data can roughly include albums (or called long videos) and user-uploaded videos (UGC). For UGC video, it has the characteristics of a lot of data information. Therefore, a large amoun...
