> 中文摘要: 利用信息检索领域中的相关算法,分析研究通过信息检索相关技术得到的相关信息,建立了一个网络新闻影响力模型来定量地计算一则新闻的影响力,从而估计它对社会安全产生影响的程度.在对大量实验结果的统计分析中发现,此方法可以有效地对新闻文章进行排序,发现不同新闻类型中最值得关注的新闻,其结果与人的定性判断结果具有较高的一致性.
Abstract:Evaluating the force of Internet news is an important aspect in the social security field. This paper establishes a quantitative analysis model for calculating the Internet news force with information retrieval methods based on the correlative information got through information retrieval technologies. This method can help people understand how great the news affects the social security. A lot of experiments, lead to a conclusion: this method can rank a stream of news effectively, and also can find most important news items from a number of news which belong to different types; its result is very close to people’s judgment.
