摘　　要：按照人们对产品的健康影响、环境污染方面的情感认知,开发用于评估产品环境形象的人工智能方法。基于“舆情环境形象”概念,从健康影响、环境污染、环境风险和情感倾向4个方面建立产品舆情环境形象评估框架,以产品的互联网传播大数据为信息源,人工标注分类语料,采用自然语言处理技术和卷积神经网络算法训练验证分类模型。进一步以33种高风险和高污染产品为分析对象,利用从互联网获取的相关新闻、评论或公众言论进行模型分类和环境形象评估,结果表明环境舆情判定模型F值为0.91,产品的环境情感极性均以正面情绪为主,受舆情讨论热点程度影响,舆情数量多的产品情感倾向占比趋于均衡化、舆情数量少的产品情感倾向占比趋于极端化。其中,化妆品、药品的环境健康风险最高,高环境风险产品分别包括凡士林、角鲨烯和咖啡因。An artificial intelligence method according to people’s emotional cognition of product health impact and environmental pollution for evaluating product environmental is developed.Based on establishing analysis framework of dimensions and emotional polarity of product environment image,the classification model is trained and verified by using natural language processing technology and convolutional neural network(CNN)algorithm,with big data of product spread on the internet as the information source and manual annotation of classification corpus.Taking 33 kinds of high-risk and high-polluting products as the analysis objects,the product-related news,comments or public comments on the internet are classified and environmental image evaluation is carried out.The result shows that the F value of the environmental public opinion judgment model is 0.91.The environmental emotional polarity of products is dominated by positive emotions,affected by the degree of public opinion discussion hotspots.The proportion of emotional tendency of products with more public opinions tends to be balanced and the proportion with less public opinions tends to be extreme.Cosmetics and drugs have the highest environmental health risk.Vaseline and squalene are the high environmental risk products of cosmetics,and for drugs is caffeine.
