The study adopt a series of tool of pra method , such as semi - structured interview , group interview , direct sorting , and household sorting , based on data from 687 rural households in 25 counties of 6 provinces covering jilin , shandong , shaanxi , shanxi , sichuan and guangxi 本研究运用参与式农村评估方法中的访谈工具?半结构式访谈,性状排序,农户分类和小组访谈工具,共调查了吉林、山东、陕西、山西、四川和广西六个省25个县的687个农户。
Through constructing the analytical framework of " institutional arrangement - extension behavior - extension performance " , carrying out semi - structure interview , case study and comparison analysis , this paper compares and probes into different operational models of techniques popularization organizations 通过构建“制度安排? ?推广行为? ?推广绩效”分析框架,并借助于半结构访谈、案例分析、比较研究,对不同技术推广组织运作模式进行比较研究。
The main task of this thesis is to apply maximum entropy model to spam filtering , and the primary framework of spam filtering system based on maximum entropy is proposed . considering the semi - structure characteristic of e - mail , features are extracted from e - mail 最后,将基于最大熵的垃圾邮件过滤方法与outlook提供的pia相结合,开发出一个垃圾邮件过滤插件,在客户端用最大熵方法实现了基于内容的垃圾邮件过滤,较好地帮助用户解决了垃圾邮件泛滥的问题。
The extensible markup language ( xml ) is a promising standard for describing semi - structured information and contents in the e - business . when xml comes to be a widespread data encoding format for web applications , safeguarding the accuracy of the information represented in xml documents will be indispensable Xml在描述电子商务中的半结构化信息及内容时具有很好的前景,但当xml成为web应用中广泛使用的编码方式时,保证xml描述信息的安全性是必不可少的。
In the gdss , techniques in communication and computer are combined with theory and method of artificial intelligence and management science as well as other special mathematical tools to promote the group who have different experiences and knowledge structure as well as shared responsibility to solve the semi - structure and non - structure problems in decision making procedure Gdss利用通信技术、计算机技术,运用人工智能( ai ) 、管理科学理论与方法及其它数学工具,促进具有不同知识结构、不同经验、共同责任的群体对半结构化、非结构化决策问题进行求解。
