【摘要】 社交网络的出现,将网络上的人际关系聚集在一起,为认识好友的好友,以及好友之间的互动与信息分享提供了可能。目前,视频分享已经成为社交网站中最重要的应用之一,研究视频分享在社交网站中的传播规律,在信息传播领域和网络传输质量方面都有着非常重要的意义。为了全面地考察社交网站中视频分享的传播规律,本文从视频分享信息的生长规律和传播规律两个方面进行了深入研究。针对研究内容所需的数据,本文设计与实现了一个视频分享测量平台,主要包括两个系统,即视频信息采集系统与视频信息解析系统。其中,视频信息采集系统主要以开心001网站上的热门视频转帖信息作为采集目标,爬取热门视频转帖的诞生时间、转帖次数、浏览次数、互动次数等信息。视频信息解析系统主要从某区域用户浏览人人网的历史数据中,获取用户分享视频的标题、链接、时间等信息。在此基础上,本文对获取到的数据进行了深入地研究和分析。一方面本文考察了开心001网站中热门视频转帖的一些特殊的生长规律。另一方面,以某区域作为研究范围,本文主要从区域外用户向区域内用户传播视频,以及区域内用户之间的视频传播两方面,对人人网中的视频分享传播进行了研究。本文构建了一个稳定的测量平台,从两方面对社交网络视频分享规律进行了研究,总结出一些非常重要的结论,对社交网络领域的信息传播研究具有重要的指导意义。更多还原

【Abstract】 With the appearance of SNS, interpersonal relationships congregate on the network, which provides the possibility of recognizing friends of friends, and interaction and information sharing between friends. Recently, video sharing has becoming one of the most important applications in social network sites. Therefore, it’s full of great significance for information dissemination and network transmission quality to study the propagation of video sharing in social network sites.In order to fully examine propagation law of video sharing in social network sites, this paper conducted in-depth research from two aspects, growth and propagation. To obtain the video sharing information for research, this paper designed and implemented a measurement platform of video sharing, including two systems, namely, video information collection system and video information parsing system. Among them, the video information collection system took Kaxin001 as collection target, crawling information like the birth time, sharing times, view times, interaction times, etc. Video information parsing system parsed data, like video titles, URL links and time, from restore files of Renren viewed by users in a certain area. On that basis, this paper conducted in-depth research and analysis. On the one hand, this paper found some special growth laws of popular videos in Kaxin001. On the other hand, with the region of a university, this paper studied the video propagation laws in Renren through two aspects, video transmission from external users to internal users, and video communication between users inside the area.This paper studied propagation laws of video sharing in social network sites, and summarized some very important conclusions. It was of important guiding significance for the research on the information dissemination of social network field.更多还原
