| titleOfInvention | Environmental risk perception evaluation method based on data mining |
| abstract | The invention discloses an environmental risk perception evaluation method based on data mining, and relates to the technical field of environmental risk perception evaluation. According to the method, firstly, text information related to public environment risk perception is rapidly mined from massive public environment appeal data, text data unrelated to environment quality is removed by adopting a data cleaning and preprocessing method, then keyword retrieval is carried out based on unsupervised and learned technologies, and finally complaint texts are comprehensively scored by adopting a TF-IDF algorithm, so that environmental health influence factors highly concerned by the public can be effectively identified, and timeliness and accuracy of public environment risk perception degree evaluation are improved. |
