Environmental pollution event information recommendation method fusing spatial relationship and emotional intensity

Abstract

The invention discloses an environmental pollution event information recommendation method fusing a spatial relationship and emotional intensity. The method comprises the following steps: S1, pollution event microblog crawling; s2, performing individual microblog crawling; s3, determining a pollution influence range based on a spatial relationship and emotional intensity; s4, user type division and data source selection; s5, microblog similarity calculation based on the ontology structure of the environmental pollution field; and S6, recommendation list generation: users can be classified according to user microblogs and information concerned by the users is recommended to the users according to user types only by inputting microblog ID numbers by the users, so that the effect of personalized environmental pollution event information recommendation is achieved.

Description

technical field [0001] The invention relates to the technical field of pollution emergency information analysis, in particular to a method for recommending environmental pollution event information that integrates spatial relationships and emotional intensity. Background technique [0002] The occurrence and spread of environmental pollution are restricted by geographical location and natural geographical conditions. The scope and degree of impact of the same type of pollution incidents are inconsistent because of the different places where they occur. For Weibo users in different geographical locations, the demand for event-related pollution information is inconsistent. For example: Weibo users within the scope of pollution influence have a strong demand for pollution information and disposal information, while Weibo users outside the scope of pollution influence have relatively weak demand for pollution information, and are more concerned about causing pollution s reason....

AI Technical Summary

Problems solved by technology

[0004] Although there are many recommended algorithms, most of them are used in emergency response in the field of disaster emergency response, and there are not many applications in the field of environmental pollution emergency response

Especially in the face of some events with a large scope of pollution and a large amount of Internet response information, there are still a lack of relatively successful and typical cases. Therefore, relevant departments lack case databases and successful and effective methods for dealing with large-scale environmental public opinion events. Drawing lessons from it makes the response more based on traditional public opinion control methods, and there are still many deficiencies in the professionalism of environmental pollution incidents and the communication of scientific ideas
