【摘要】：微博，也可稱(chēng)為微博客（Micro,Blog），是一種新型媒體平臺(tái)。用戶(hù)可以在這個(gè)新型媒體平臺(tái)上產(chǎn)生信息、傳播信息以及獲取信息。微博媒體的內(nèi)在結(jié)構(gòu)是一個(gè)以用戶(hù)為節(jié)點(diǎn)，用戶(hù)之間的關(guān)系為邊的一個(gè)社會(huì)網(wǎng)絡(luò)。當(dāng)新的信息產(chǎn)生之后，其余用戶(hù)的轉(zhuǎn)發(fā)就會(huì)造成信息在該社會(huì)網(wǎng)絡(luò)上的流動(dòng)，也可以稱(chēng)為信息在該社會(huì)網(wǎng)絡(luò)上傳播。對(duì)微博媒體中的信息傳播的研究包括展現(xiàn)完整的傳播路徑，傳播范圍和速度分析，關(guān)鍵節(jié)點(diǎn)分析等。這些研究也可以指導(dǎo)實(shí)際應(yīng)用，，例如：微博營(yíng)銷(xiāo)、謠言控制、廣告投放、輿情分析等。所以對(duì)于微博社會(huì)媒體中信息傳播進(jìn)行研究具有重大意義。 本文的主要任務(wù)是站在輿情分析的角度對(duì)新浪微博媒體中的信息傳播進(jìn)行分析，同時(shí)給出了一個(gè)新浪微博輿情分析系統(tǒng)。本文的研究包括：數(shù)據(jù)獲取、信息傳播分析、微博輿情分析。本文工作如下： 首先是新浪微博數(shù)據(jù)獲取。在該部分，主要簡(jiǎn)單介紹新浪微博數(shù)據(jù)結(jié)構(gòu)以及目前比較流行的獲取新浪微博數(shù)據(jù)的兩種方法：利用新浪開(kāi)放平臺(tái)提供的API和利用新浪微博網(wǎng)頁(yè)爬蟲(chóng)。并分析兩種方法各自?xún)?yōu)勢(shì)。 其次是新浪微博信息傳播分析。在該部分，主要重點(diǎn)介紹信息傳播樹(shù)的概念，以及在新浪微博媒體中信息傳播樹(shù)的生成算法。并以信息傳播樹(shù)為基礎(chǔ)，介紹結(jié)構(gòu)分析、內(nèi)容分析、人群分析的概念。 最后是信息傳播在輿情分析中的應(yīng)用，主要包括兩個(gè)部分：新浪微博數(shù)據(jù)爬蟲(chóng)和新浪微博信息傳播分析與事件統(tǒng)計(jì)分析。在數(shù)據(jù)爬蟲(chóng)部分將會(huì)介紹利用新浪微博開(kāi)放平臺(tái)提供的API設(shè)計(jì)的全網(wǎng)爬蟲(chóng)。在新浪微博信息傳播分析與事件統(tǒng)計(jì)部分將會(huì)把對(duì)信息傳播樹(shù)的各項(xiàng)分析結(jié)果可視化給用戶(hù)。
[Abstract]:Weibo, also known as Weibo, is a new media platform on which users can generate information. The internal structure of Weibo media is a social network with the user as the node and the relationship between the users as the edge. When the new information is generated.
