Abstract

The invention discloses a hot event mining method based on a large-scale knowledge base. The method is characterized by including the steps of based on data acquired through the internet, automatically establishing a text-understanding-oriented large-scale knowledge base, and allowing for automatic optimization and knowledge updating of the base; based on the large-scale knowledge base, performing structural information extraction on short texts to be detected, sorting the short texts to be detected, according to extracted structural information, and screening out corresponding event texts; based on the large-scale knowledge base, clustering the screened event texts to screen out hot events. The method has the advantages that structural knowledge representation is automatically extracted from the internet, structural tuple representation is established for semantic relation between instances and concepts, a knowledge back-tracking mode is provided, and accuracy in extraction of structural information from short texts is improved.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a method for mining hot events in short texts based on a large-scale knowledge base. Background technique [0002] With the advent of the era of big data, the effective acquisition and professional processing of massive data information tests the intelligence level of computers. Many institutions and individuals are beginning to research how to make computers understand the human mind and our world. So far, this is still a very challenging goal. Under the above background, hot event mining for short texts such as Weibo has gradually become a research hotspot. [0003] At the beginning of the event detection task, the vector space model is the most widely used method. In the vector space model, one dimension represents the report and the other dimension represents the feature, so that each report can be expressed by a vector, and then through the There are e...
