针对微博中用户影响力分析这个问题,提出用户影响力的计算方法。该方法首先提出用户自身影响力以及用户被影响力的概念,并根据用户自身特征与用户粉丝情况得出其计算公式,从而可以综合考虑用户在微博中的所有信息,计算出用户影响力。实验结果表明,这种计算方法能比较好地反映用户在其粉丝中的影响力。 相似文献

在微博平台中用户的消息以流的形式按照时间顺序到达系统,对微博数据流的有效管理可以及时地响应用户的查询操作。基于数据库的数据世系思想,提出了一种基于数据世系的微博信息管理方法。首先,根据事件的产生、发展以及变化,将同一社会事件包含的消息定义为数据世系;其次,将微博消息流划分为不同的数据世系,并根据新消息动态地维护数据世系集合;最后,应用数据世系中的文本消息响应用户的查询。实验表明,基于数据世系的微博信息管理方法使用的内存少,运行效率高,可用于微博消息流的实时处理及查询响应工作。 相似文献

Microblogging has become one of the most popular social communication styles in the world. Much research has already addressed this hot issue; however, studies examining the intentions behind microblogging behaviors are limited. This study extended the theory of planned behavior (TPB) to predict intention to microblog and other behaviors. The results showed that social identity was the greatest predictor of intention, followed by attitude and perceived behavioral control. Social identity fully mediated the effects of subjective norms and self-identity on intention. Intention significantly predicted users' microblogging behaviors. These results have important implications for industry players and marketing managers. 相似文献

Despite a substantial literature suggests that computer-mediated communication impact individuals’ various psychosocial factors, relatively few studies have elucidated the underlying mechanism behind these associations. Building upon self-disclosure theory and previous studies, the principal purpose of this present research is to systematically explore the relationships among microblog utilization, online self-disclosure, friendship maintenance, and perceived life satisfaction. A web-based survey was implemented using a total of 426 university students in Northwestern China. Structural equation modeling reveals that intensity of microblog use is positively associated with these students’ friendship maintenance and life satisfaction. Additionally, online self-disclosure plays the crucial mediatory role in the relationships between microblog use, quality of relationships, and gratification with life. The results imply that as microbloggers disclosure their inner thoughts or emotional states with other users online, they could foster their friendship maintenance and obtain greater life satisfaction. However, contrary to the expectation, students’ friendship maintenance is not discovered to be a significant predictor of the sense of life satisfaction in the online environment. Overall, these obtained outcomes of the empirical work could offer new insights into the deep comprehending of the social psychological process of microblogging among younger generation in the new media context. 相似文献

基于NPP/VIIRS夜间灯光遥感影像和微博签到数据,利用局部等值线树算法和层次结构图谱,对2014年郑州主城区的城市中心及其内部空间结构进行识别与表达。结果表明:2014年郑州市共识别出3株局部等值线树,包括18个城市中心和11个城市中心复合区;“主树”的等值线树层级为10级,老城区城市中心发育良好,北部地区城市中心的空间分布不均衡且较为破碎;城市中心按照城市职能分为4类,城市综合中心的空间分布较为均匀,商业中心和工业中心次之;城市中心分为5个等级,空间分布上呈现“由里到外”依次降低的趋势。 相似文献
