Embodiment 1

[0047] A social media hot topic extraction method, see figure 2 Including the following steps:

[0048] S10. Filtering and summarizing the collected Internet text information data;

[0049] S20, using a text clustering algorithm to gather the filtered Internet information data of the same theme;

[0050] S30. After the Internet text information data is clustered, a text abstract is generated for the topic selected by the user, thereby completing hotspot extraction and displaying the corresponding topic.

[0051] A method for extracting hot topics in social media, wherein the collected Internet text information data is filtered and summarized. In the process of collecting corpus, it is necessary to collect as comprehensive and different corpus as possible, and the same article is often reproduced in On multiple platforms, take the 15,000 news corpus about Trump as an example: the corpus with different content accounts for only 8.5% of the total corpus, and in this only 8.5%,...

Abstract

The invention discloses a social media hot topic extraction method and system. The hot topic extraction method comprises the following steps: filtering and concluding collected Internet text information data, then gathering Internet data information of the same topic by adopting a text clustering algorithm, clustering the Internet data information, and generating a text abstract for the selected topic. The hot topic extraction system comprises a data screening calculation module, a topic clustering module and a topic abstract extraction module, wherein the data screening calculation module isused for filtering and concluding the collected Internet text information data; the topic clustering module adopts the text clustering algorithm to cluster the filtered Internet text information dataof the same topic; and the topic abstract extraction module is used for generating a text abstract from the corresponding clustered Internet text information data according to a topic selected by a user so as to complete hotspot extraction. The method and the system improve the extraction quality of the social media hot topics and have relatively high practical value.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and relates to a method and system suitable for extracting hot topics from various social media data. Background technique [0002] With the continuous and in-depth development of information technology and the Internet, social media, including Weibo and WeChat public accounts, have become more and more influential and time-sensitive. main channel. However, the vigorous development of social media has also led to the continuous growth of the relevant data scale. Taking Sina Weibo as an example, its monthly active users of Weibo in 2018 were 462 million, an increase of 70 million+ for three consecutive years, and the number of vertical fields expanded to 60, of which 32 fields had a monthly reading volume of over 10 billion. How to obtain social media information related to brand and development in a timely manner in the mass and rapidly changing social media has become an important topic ...
