摘要
新媒体时代的信息具有数量巨大,传播快速等特点。单独的信息往往在不同的新媒体形式间传递,并在各自的平台上快速扩散。研究发现要测量新媒体信息传播影响力,就必须先测量参与传播信息的各个新媒体的传播权重。通过计算历史上各个新媒体传播过的信息最终扩散范围的数据,分别测量自媒体的代表(微博、微信公众号)和网络主流媒体的代表(门户网站、移动新闻客户端)的媒体影响力指数。这一指数是相对稳定的。之后当某一条新媒体信息在互联网上出现时,就可以通过参与传播的媒体历史影响力的聚合,测量该信息的传播影响度。
There is a huge number of information in the age of new media, which spreads quickly. Separate information is often transferred between different forms of new media, and spreads on the respective platform quickly. The study finds new media information spreading influence, which must be measured in the dissemination of information for each new media weight. By computing eventually spread data of disseminate information on the history through various new media, the press representatives （weibo, wechat-public） and network representatives of mainstream media （news portals, news apps） index of media influence are measured. The index is relatively stable. When a piece of new media information appears on the Internet, the transmission of that information can be measured by the media in the dissemination of the historical influence of polymerization.
