【摘要】：微博是web2.0應(yīng)用中的一大主流模式,其開放性、交互性、便捷性等特點(diǎn)受到眾多用戶的青睞,成為移動(dòng)互聯(lián)網(wǎng)時(shí)代最具發(fā)展?jié)摿Φ膽?yīng)用之一。微博平臺(tái)快速發(fā)展的同時(shí),各種亂象叢生,信息質(zhì)量問題嚴(yán)重,為其發(fā)展帶來(lái)了困擾。由于“把關(guān)人”的缺失、信息的碎片化特征、用戶水平良莠不齊,微博中充斥著種種亂象。龐大的用戶群與實(shí)時(shí)傳播功能造成了微博信息泛濫、謠言四起,信息發(fā)布的便捷與轉(zhuǎn)發(fā)功能造成大量的信息冗余,信息發(fā)布中“把關(guān)人”角色的缺失使失真信息、瑣碎信息和庸俗信息充斥著整個(gè)微博。同時(shí),微博營(yíng)銷的快速發(fā)展引發(fā)了一系列不規(guī)范操作,甚至違法犯罪行為。根據(jù)CNNIC對(duì)用戶使用微博中遇到的問題進(jìn)行調(diào)查顯示,目前微博承載的信息內(nèi)容不能滿足用戶的質(zhì)量需求,主要表現(xiàn)在信息量過大、有效價(jià)值不高且獲取難等方面。微博信息內(nèi)容質(zhì)量問題已成為影響微博平臺(tái)健康發(fā)展、網(wǎng)絡(luò)信息資源有效利用的重要問題,微博信息資源質(zhì)量治理迫在眉睫。目前國(guó)內(nèi)外對(duì)于微博信息質(zhì)量的研究,主要集中在信息質(zhì)量評(píng)價(jià)、信息質(zhì)量問題分析與對(duì)策兩個(gè)方面。在信息質(zhì)量評(píng)價(jià)方面,國(guó)外研究以實(shí)證分析為主,而國(guó)內(nèi)則以構(gòu)建評(píng)價(jià)指標(biāo)體系為主；在信息質(zhì)量問題分析研究中,國(guó)外側(cè)重于利用信息技術(shù)解決具體的質(zhì)量問題,而國(guó)內(nèi)則更多地針對(duì)微博中某一領(lǐng)域信息分析問題并提出對(duì)策,具有較強(qiáng)的針對(duì)性�？傊�,這些研究多是圍繞微博信息質(zhì)量評(píng)價(jià)和質(zhì)量問題分析與解決兩個(gè)方面開展的,對(duì)于微博信息內(nèi)容質(zhì)量評(píng)價(jià)及其對(duì)用戶利用的影響分析的研究則較少。微博信息內(nèi)容質(zhì)量評(píng)價(jià)及影響分析可以更準(zhǔn)確把握影響用戶利用微博信息的關(guān)鍵質(zhì)量因素,從而有效提高微博信息內(nèi)容質(zhì)量及其利用率。本文基于這一思想,以新浪微博數(shù)據(jù)為樣本進(jìn)行實(shí)證研究,開展微博信息內(nèi)容質(zhì)量評(píng)價(jià)及質(zhì)量對(duì)比分析,并深入分析微博信息質(zhì)量對(duì)用戶利用情況的影響,以挖掘影響微博信息利用率的關(guān)鍵質(zhì)量要素,為控制與改進(jìn)微博信息質(zhì)量、提高微博信息利用率提供策略與建議。 論文的結(jié)構(gòu)分為緒論和正文,共計(jì)8章內(nèi)容。 第一章緒論部分,主要介紹選題背景與研究意義、國(guó)內(nèi)外研究現(xiàn)狀、本研究的內(nèi)容、方法以及創(chuàng)新之處。 第二章是本論文的相關(guān)概念與理論基礎(chǔ),包括信息質(zhì)量、信息評(píng)價(jià)和內(nèi)容分析法3個(gè)方面的相關(guān)理論。根據(jù)信息質(zhì)量基礎(chǔ)理論界定微博信息質(zhì)量的內(nèi)涵與范疇,為信息內(nèi)容質(zhì)量評(píng)價(jià)及對(duì)比分析提供理論基礎(chǔ)。信息評(píng)價(jià)理論為實(shí)現(xiàn)微博信息內(nèi)容質(zhì)量的量化評(píng)價(jià)提供了研究方法與工具,為系統(tǒng)開展微博信息內(nèi)容質(zhì)量評(píng)價(jià)提供了理論支持。內(nèi)容分析法相關(guān)理論主要用于微博信息內(nèi)容類型的歸類與分析,這一過程需要將信息內(nèi)容按照所設(shè)置的類型進(jìn)行逐一歸類。內(nèi)容分析法為這一過程與具體操作提供了理論支持和過程指導(dǎo)。 第三章是構(gòu)建微博信息內(nèi)容質(zhì)量評(píng)價(jià)的理論框架,并提出信息內(nèi)容質(zhì)量對(duì)微博利用影響的理論假設(shè)。即根據(jù)信息質(zhì)量理論及微博信息的特點(diǎn),設(shè)置基于微博信息內(nèi)容的客觀信息質(zhì)量評(píng)價(jià)指標(biāo)體系,并通過用戶調(diào)研對(duì)指標(biāo)權(quán)重進(jìn)行賦值,構(gòu)建微博信息質(zhì)量評(píng)價(jià)模型,為量化評(píng)價(jià)微博信息內(nèi)容質(zhì)量提供理論基礎(chǔ)。在此基礎(chǔ)上,分析微博信息內(nèi)容質(zhì)量對(duì)微博利用的影響,并提出理論假設(shè),為后文的實(shí)證研究建立理論基礎(chǔ)。 第四章是對(duì)微博信息內(nèi)容質(zhì)量進(jìn)行分析與評(píng)價(jià),并總結(jié)不同領(lǐng)域用戶微博信息內(nèi)容的質(zhì)量特征。以新浪微博為例,選取科技、公安、房地產(chǎn)和環(huán)保四個(gè)領(lǐng)域的部分微博用戶,采集用戶微博信息內(nèi)容作為樣本數(shù)據(jù),并根據(jù)微博質(zhì)量指標(biāo)進(jìn)行質(zhì)量分析與評(píng)價(jià),總結(jié)不同領(lǐng)域用戶的微博信息質(zhì)量特征。 第五章是采用獨(dú)立樣本T檢驗(yàn)方法對(duì)不同領(lǐng)域的用戶群體微博頁(yè)面信息內(nèi)容質(zhì)量進(jìn)行差異性分析,以對(duì)比不同用戶群體的微博頁(yè)面信息內(nèi)容在質(zhì)量描述指標(biāo)上的差異,挖掘各用戶群體的質(zhì)量特征及其差異性。 第六章和第七章主要分析了微博信息內(nèi)容質(zhì)量對(duì)用戶利用的影響。用戶對(duì)微博信息的利用主要表現(xiàn)為微博轉(zhuǎn)發(fā)與微博評(píng)論兩個(gè)方面,體現(xiàn)了用戶對(duì)微博信息的主觀質(zhì)量感知。第六章是以微博信息內(nèi)容質(zhì)量描述指標(biāo)為自變量,以微博轉(zhuǎn)發(fā)為因變量,通過實(shí)證研究分析信息內(nèi)容質(zhì)量對(duì)微博轉(zhuǎn)發(fā)情況的影響。在內(nèi)容組織上,根據(jù)微博用戶所屬的領(lǐng)域,從信息質(zhì)量角度分別分析科技用戶、房地產(chǎn)用戶、公安用戶和環(huán)保用戶這四個(gè)用戶群體微博中信息內(nèi)容質(zhì)量對(duì)微博轉(zhuǎn)發(fā)情況的影響,以挖掘不同類型微博中的關(guān)鍵質(zhì)量影響因素。第七章是根據(jù)樣本數(shù)據(jù)中包含的科技用戶、房地產(chǎn)用戶、公安用戶和環(huán)保用戶四個(gè)群體的微博信息,分別對(duì)這四個(gè)領(lǐng)域用戶微博頁(yè)面中信息內(nèi)容質(zhì)量指標(biāo)對(duì)微博評(píng)論的影響作用進(jìn)行分析,以挖掘影響微博評(píng)論的關(guān)鍵質(zhì)量要素。 第八章是對(duì)全文的研究進(jìn)行總結(jié)與展望,包括研究結(jié)論與啟示、研究不足與展望。 經(jīng)過理論與實(shí)證分析,本文得到以下三個(gè)方面的結(jié)論： 第一,不同領(lǐng)域的用戶群體在發(fā)布微博信息時(shí)體現(xiàn)出了不同的信息質(zhì)量特征,說(shuō)明用戶所處的行業(yè)和領(lǐng)域?qū)ζ湮⒉╉?yè)面信息內(nèi)容質(zhì)量具有顯著的影響作用。 第二,在信息質(zhì)量指標(biāo)方面,用戶群體之間的顯著性差異較多的是信息類型和信息熱度,其次是文本字?jǐn)?shù)和超鏈接信息量,顯著性差異較少的是信息真實(shí)性質(zhì)量和信息編輯的專業(yè)性,說(shuō)明微博用戶所處的行業(yè)和領(lǐng)域特征對(duì)微博信息類型和信息熱度影響較大,而對(duì)信息的互動(dòng)性和編輯質(zhì)量影響不大。 第三,影響微博轉(zhuǎn)發(fā)的關(guān)鍵質(zhì)量因素依次為文本信息量、信息內(nèi)容類型和信息真實(shí)性質(zhì)量,而超鏈接信息量、信息熱度和信息編輯質(zhì)量對(duì)微博轉(zhuǎn)發(fā)未形成統(tǒng)一的、顯著的影響作用。影響微博評(píng)論的關(guān)鍵質(zhì)量因素依次為文本信息量、信息真實(shí)性質(zhì)量和信息內(nèi)容類型,與微博轉(zhuǎn)發(fā)的質(zhì)量影響因素基本一致,故微博信息內(nèi)容質(zhì)量中的文本信息量、信息內(nèi)容類型和信息真實(shí)性質(zhì)量是影響微博信息利用的關(guān)鍵質(zhì)量要素。
[Abstract]:Micro-blog is a major mode in the Web2.0 application. Its openness, interactivity, convenience and other characteristics have been favored by many users. It has become one of the most potential applications in the era of mobile Internet. At the same time, the rapid development of the micro-blog platform, a variety of chaos, and serious information quality problems, has brought trouble for its development. The lack of people, the fragmented character of information, and the diversity of the user's level, the micro-blog is full of chaos. The huge user group and the real-time communication function have caused the flood of information of micro-blog. Four rumors have been made, and the convenience and forwarding function of the information release cause a lot of information redundancy, and the lack of the "gatekeeper" role in the information release makes the distortion letter Interest, trivial information and vulgar information flooded the whole micro-blog. At the same time, the rapid development of micro-blog marketing triggered a series of non standard operations, even illegal criminal behavior. According to the problems encountered by the users in micro-blog, the information contained by the CNNIC can not meet the user's quality requirements, mainly in the performance. The quality of information content of micro-blog has become an important problem that affects the healthy development of the micro-blog platform and the effective utilization of the network information resources. The quality control of the information resources of micro-blog is imminent. At present, the research on the quality of the information of the micro-blog is mainly focused on the evaluation of the information quality, There are two aspects of information quality analysis and countermeasures. In the aspect of information quality evaluation, foreign research is mainly based on empirical analysis, while domestic is mainly based on the construction of evaluation index system. In the analysis of information quality problems, foreign countries focus on the use of information technology to solve specific quality problems, while domestic are more targeted at one of the micro-blog leaders. The domain information analysis and the countermeasures are highly targeted. In a word, these studies are mostly carried out around the two aspects of micro-blog information quality evaluation and quality analysis and resolution. The research on the quality evaluation of micro-blog information content and its impact on the user utilization is less. The quality evaluation and influence of micro-blog information content Analysis can more accurately grasp the key quality factors that affect users' use of micro-blog information, so as to effectively improve the quality and utilization of micro-blog information content. Based on this idea, this paper takes Sina micro-blog data as a sample to carry out empirical research, carries out the quality evaluation and quality contrast analysis of micro-blog information content, and analyzes the quality of micro-blog information. In order to tap the key quality factors that affect the information utilization rate of micro-blog, we can provide strategies and suggestions for controlling and improving the information quality of micro-blog and improving the information utilization rate of micro-blog.
The structure of the thesis is divided into 8 parts: introduction and text.
The first chapter is the introduction, which mainly introduces the background and significance of the research, the research status at home and abroad, the contents, methods and innovations of this research.
The second chapter is the related concept and theoretical basis of this paper, including information quality, information evaluation and content analysis of the 3 aspects of the related theory. According to the information quality basic theory to define the content and category of the information quality of micro-blog, to provide a theoretical basis for the quality evaluation and comparative analysis of information content. Information evaluation theory for the realization of micro-blog letter The quantitative evaluation of the quality of interest content provides a research method and tool, which provides a theoretical support for the evaluation of micro-blog information content quality evaluation system. The related theory of content analysis method is mainly used for the classification and analysis of micro-blog information content types. This process needs to classify information content according to the types set. Content analysis This method provides theoretical support and process guidance for this process and concrete operation.
The third chapter is to construct the theoretical framework of the quality evaluation of micro-blog information content, and put forward the theoretical hypothesis of the influence of information content quality to the use of micro-blog. That is, according to the information quality theory and the characteristics of micro-blog information, the objective information quality evaluation index system based on the information content of the micro-blog is set up, and the index weight is assigned by the user investigation. The micro-blog information quality evaluation model is constructed to provide a theoretical basis for quantifying and evaluating the content quality of micro-blog information. On this basis, the influence of the content quality of micro-blog information on the micro-blog utilization is analyzed, and the theoretical hypothesis is put forward to establish the theoretical basis for the empirical research of the later literature.
The fourth chapter is to analyze and evaluate the quality of micro-blog information content, and summarize the quality characteristics of micro-blog information content in different fields. Take Sina micro-blog as an example, select some micro-blog users in the four fields of science and technology, public security, real estate and environmental protection, collect the user's micro-blog information internal capacity as sample data, and carry out according to the qualitative indicators of micro-blog. Quality analysis and evaluation summarize micro-blog's information quality characteristics of users in different fields.
The fifth chapter is the use of independent sample T test method to analyze the quality of micro-blog page information content of different user groups in different fields, in order to compare the difference between the content of micro-blog page information content of different user groups on the quality description index, and to excavate the quality characteristics and differences of each user group.
The sixth chapter and the seventh chapter mainly analyze the influence of the micro-blog information content quality to the user utilization. The user's use of micro-blog information is mainly shown in the two aspects of micro-blog forwarding and micro-blog review, which embodies the user's subjective quality perception of micro-blog information. The sixth chapter is based on the qualitative description index of micro-blog information as the independent variable, and turning to micro-blog. As a dependent variable, the effect of information content quality on micro-blog forwarding is analyzed through empirical research. In content organization, according to the domain of micro-blog users, from the perspective of information quality, the information content quality of the four users, such as science and technology users, real estate users, public security users and environmental users, is analyzed by the quality of information content of micro-blog. The seventh chapter is based on the micro-blog information of the scientific and technological users, the real estate users, the public security users and the four groups of environmental users in the sample data, and the influence of the content quality index of the CITIC content on the micro-blog pages in these four fields to the micro-blog reviews, respectively, is made in the seventh chapter. Conduct analysis to identify key quality factors that affect micro-blog reviews.
The eighth chapter is the summary and Prospect of the research, including research conclusions and enlightenment, research deficiencies and prospects.
After theoretical and empirical analysis, the following three conclusions can be drawn:
First, different user groups in different fields show different information quality characteristics when issuing micro-blog information, which shows that the industry and domain of users have a significant impact on the content quality of micro-blog page information.
Second, in the information quality index, the significant difference between the user groups is the information type and the information heat, followed by the text word number and the hyperlink information. The significant difference is the quality of information authenticity and the professionalism of the information editing, which explains the industry and domain characteristics of micro-blog users to the micro-blog information type. It has great influence on information intensity, but has little influence on information interaction and editing quality.
Third, the key quality factors affecting micro-blog forwarding are the volume of text information, the type of information content and the quality of information authenticity, and the amount of hyperlink information, the information heat and the quality of information editing have not formed a unified and significant influence on micro-blog forwarding. The key quality factors affecting the micro-blog review are the volume of text information in turn, and the information is true The real quality and information content type are basically the same as the quality influencing factors of micro-blog forwarding. Therefore, the quantity of text information, the type of information content and the quality of information authenticity in the content quality of micro-blog are the key quality factors that affect the use of micro-blog information.
