Embodiment Construction

[0041] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0042] figure 1 It is a schematic flowchart of Embodiment 1 of the multi-granularity real-time hotspot aggregation method provided by the present invention. The execution subject of this embodiment may be a multi-granularity real-time hotspot aggregation system, such as figure 1 As shown, the method provided in this embodiment includes the following steps:

[0043] S101. Perform data cleaning processing on the input streaming data, and represent the processed streaming data as structured data.

[0044] Specifically, distributed crawler technology can be used to collect streaming data in the network (for example: Sina Weibo, Sina News, Netease News, etc.), and these streaming data include hot information such as events and news.

[0045] After the collected streaming data is input into the system, the data can be cleaned first according to the set rules to filt...

Abstract

The invention provides a multi-granularity real-time hot spot aggregation method, comprising: performing data cleaning processing on input streaming data, showing the processed streaming data in structural data; performing word segmentation on the structural data in first preset time slice, and calculating weight of each segmented word in all streaming data; according to the weight of each segmented word, calculating weight of each event in the current time slice; aggregating events, and according to the weight of each event, calculating weight of each event cluster after aggregation; and according to the weight of each event cluster, generating a sorted event list. The technical scheme improves granularity of a final event display result, and event integrity and accuracy, and provides convenience for a user to rapidly and accurately obtain hot spot information.

Description

technical field [0001] The invention relates to information retrieval technology, in particular to a multi-granularity real-time hotspot aggregation method. Background technique [0002] The Internet produces a large amount of information all the time, among which valuable and high-volume information can be regarded as hot information. Traditional news media manually edit and publish these hot information to form news, so that people can keep abreast of real-time information. Information, to grasp the latest information. This method of artificially generating news can ensure the accuracy of the news, but it takes a lot of time and sacrifices the real-time and objectivity of the news in a certain sense. [0003] With the development and rise of modern artificial intelligence and natural language processing technology, a non-artificial hotspot event detection system that processes a large amount of streaming information text data has been developed, and machines are used inst...
