The invention discloses a visual presentation method of topic evolution, which includes: extracting topics of multiple text data related to the same event, and determining the association relationship between each of the topics, so as to establish a topic flow; filtering out a plurality of first topics including important events from the topics; extracting the keywords of each of the first topics, and determining the association relationship between the keywords of each of the first topics; and converting each of the first topics Keywords of a topic and their associated relationships are added to the topic stream to generate a topic evolution context map corresponding to the plurality of text materials. The present invention also provides an application server and a computer-readable storage medium. The topic evolution visualization method, application server and computer-readable storage medium provided by the present invention can visualize the topic evolution process of an event, allowing users to quickly understand and analyze the entire event evolution process.
Description
technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a visual presentation method of topic evolution, an application server and a computer-readable storage medium. Background technique [0002] In the era of information explosion, people can read and download various news reports on a news topic for free from the Internet. Due to the large number of related news articles about a news topic (especially hot news topics) on the Internet, it is difficult to efficiently and save time to understand the development trend and evolution process of the target news topic from the numerous related news reports. Understanding the evolution of some topics on social media has important implications for investors / managers alike. When investors / managers understand the deep meaning of the topic, they can make appropriate judgments and take further action accordingly. However, it is difficult to analyze the temporal evolution ...
