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%,...
Embodiment 2
[0102] A social media hot topic extraction system, refer to figure 1 The system described therein includes a data screening module, a topic clustering module and a topic summary extraction module;
[0103] The data screening module filters and summarizes the collected Internet text information data;
[0104] Described topic clustering module adopts text clustering algorithm to gather the filtered Internet text information data of the same topic;
[0105] The topic summary extraction module generates a text summary from the corresponding clustered Internet text information data according to the topic selected by the user, thereby completing the hotspot extraction.
[0106] A kind of social media hot topic extracting system described, wherein said data screening module specifically performs the following steps:
[0107] S11. Calculate the sensitive hash fingerprint of the acquired Internet text information data;
[0108] S12. Using sensitive hash fingerprints to filter repeat...
