基于直觉模糊推理的网络舆情预警方法*

为解决网络舆情预警等级问题,提出了一种基于直觉模糊推理的网络舆情预警方法。借鉴战场态势分析思想,对网络舆情态势分析的原理进行了阐述,选取了适合计算机实现的七个网络舆情态势分析模式对预警等级进行判断。选择七个舆情话题进行实验,实验结果表明,该方法能够准确地估计出威胁等级,符合专家经验判断,说明该方法是可行的。     

旅游网络舆情热点事件监测与预警指标体系构建——以海南国际旅游岛为例

文章以海南国际旅游岛旅游舆情事件为研究对象,分析总结了2013年以来海南三亚主要旅游网络舆情事件,围绕网络舆情事件的发布主体、传播媒介、舆情受众、内容要素4个维度和舆情发展情况构建网络舆情监测指标体系和预警警戒,最后提出了建立海南旅游网络舆情总体预案,健全网络舆情事件协调机制和创新网络沟通平台的相关策略。

微博走进公安工作

微博这种新兴的网络交流方式越来越受到公众的关注,正在成为继博客之后网民们相互交流的新平台,这种集发布信息、互动交流于一体的网络工具也为公安机关所关注,各级公安机关纷纷对公安微博表现出了极大的热情,给新形势下的公安工作带来了新的契机。公安机关开设微博可以带来以下好处:首先,公安微博拉近了警民距离,提高了警察自身的公信力;其次,公安微博能使公安机关站在信息发布的制高点,及时消除谣言,还原真相;最后,公安微博能为侦查提供线索,为破案开辟新思路。总之,公安微博的开辟为公安工作带来了可喜的变化,小小的"微博110"正在为社会的稳定,人民的安居乐业贡献自己的力量。     

基于情感词典扩展技术的网络舆情倾向性分析

随着Web2.0时代的到来,网络已逐渐成为反映社会舆情的重要载体之一,网络舆情发现及网民的观点和倾向性挖掘也成为新的研究热点,但是目前尚无有效反应网民对热点事件或话题总体态度的舆情分析系统.本文针对网民关于话题评论简单、数目众多的特点,应用HowNet和NTUSD两种资源对现有情感词典进行扩展,建立了一个新的、具有倾向程度的情感词典.基于扩展的情感词典,开发了一个半自动化网络舆情分析系统.该系统能够为用户提供更加细致、准确的评论倾向性分析结果.     

大学生网络舆论引导的多元协同及危机处理

阐述了网络舆论引导具有多元性,认为技术控制是网络舆论引导最直接的核心手段,但并非网络舆论引导的唯一路径,提出对大学生网络舆论的科学引导应以技术控制为核心,以思想引导为基础,以法制约束为保障,以道德自律为目的,其危机处理有赖于高校校园网络管理部门的联合.     

Solving the privacy paradox: A counter-argument experimental approach

This study investigates why ordinary online users highly concerned about the misuse of personal information do not adopt privacy-protective behaviors, or even engage in risky behaviors, on the Internet. Given that people have few chances to directly experience privacy infringement and tend to be unfamiliar with technical terms, their opinions as reflected in conventional polls tend to be instantaneous reactions to survey questionnaires, lacking thoughtfulness. By adopting a counterargument experimental technique, this study produced three important findings: (1) people’s opinions about online privacy are swayed after being presented with a message containing a counterargument; (2) this persuasion effect is pronounced among people with a low level of online knowledge or who assess the presented message’s argument as strong; and (3) the privacy paradox is found in conventional polls but disappears in counterargument conditions. These findings imply that opinions concerning online privacy should not be estimated through conventional polling. Rather, alternative polls (e.g., deliberative polls) should be adopted for online privacy policy-making.     

Reflectivity Model of Low Grazing Angle Radar Sea Clutter

The commonly used reflectivity models of radar sea clutter are summarized. Among these models, the adjusted Barton model and the adjusted Morchin model are compared. From the analysis result, the γ-p reflectivity model is presented for low grazing angle radar sea clutter by the adjustment of the original Barton reflectivity model. The model takes into account radar frequency, grazing angle, sea condition, and polarization property. The influences of these factors on the proposed model are analyzed. The model absorbs the merits from commonly used reflectivity models for sea clutter. It introduces several researchers‘ opinions, and extends them. And it accounts for the reflectivity at arbitrary radar frequency from VHF to X-band, arbitrary low grazing angle, arbitrary sea condition and different polarization property. One of the main results is the proposed γ-p reflectivity model can reflect the influence of polarization on sea clutter reflectivity to some extent. The proposed γ-p reflectivity model of low-angle radar-sea clutter is validated by comparing the simulated and statistically experimental data.     

四川白酒图谋新突破——2004年四川白酒行业年会述评

当四川白酒存在危机和问题时，特邀请了全国著名的权威、专家、企业负责人等，为川酒“会诊”，共同为四川白酒的发展出谋划策。川酒“小而全”问题较严重，酒业资源需好好整合；酒类科研、技术、管理、营销人才的不足。是制约四川酒业发展的重要因素；企业一定要重视应用技术基础的研究，基础研究对于生产工艺及产品质量、产量的提高具有关联性的重大作用。是企业发展的基点。并应加强人才、品牌的培养。(丹妮)     

Opinions about mental illness: Hospital social atmosphere profiles and their relevance to effectiveness.

For a sample of 12 VA mental hospitals, OMI data were obtained on representative 50% samples of hospital employees, clustered into hospital social atmosphere types, and related to time in community, adjusted for prognosis of patients admitted to these hospitals. It was found that authoritarian-restrictiveness was negatively related to in-community days and that other atmosphere types were positively related.
