【摘要】：隨著互聯(lián)網(wǎng)的迅猛發(fā)展,信息量呈指數(shù)級(jí)激增,海量的文獻(xiàn)資源為科研活動(dòng)提供了支撐,同時(shí)也造成了信息過(guò)載。研究表明,研究生在科研活動(dòng)中花費(fèi)了大量的時(shí)間進(jìn)行信息查詢,大約占到整個(gè)科研過(guò)程的一半,因此對(duì)研究生信息行為的研究具有重要意義。通過(guò)對(duì)現(xiàn)有研究成果的梳理,論文將研究生的個(gè)體特征分為性別、專業(yè)、學(xué)歷和高校等四個(gè)方面；將Robinson的情感認(rèn)知理論用于判斷任務(wù)復(fù)雜性；根據(jù)Wilson的信息行為定義將研究生信息行為分為信息檢索途徑、信息檢索方式、信息交流和信息利用等四個(gè)方面；據(jù)此作者構(gòu)建個(gè)體特征和任務(wù)復(fù)雜度對(duì)研究生信息行為的影響模型。本文以南京大學(xué)、浙江大學(xué)、東南大學(xué)和南京郵電大學(xué)在讀研究生為研究對(duì)象,采用調(diào)查問(wèn)卷(問(wèn)卷主體包括研究生個(gè)體特征、任務(wù)復(fù)雜度判斷和研究生信息行為等三部分)收集研究數(shù)據(jù),用肯德?tīng)栂嚓P(guān)系數(shù)探討了個(gè)體特征對(duì)研究生信息行為的影響,用結(jié)構(gòu)方程模型分析了任務(wù)復(fù)雜度對(duì)研究生信息行為的影響。研究結(jié)果顯示：性別對(duì)研究生信息行為的影響甚微,僅對(duì)研究生檢索方式的選擇存在微弱影響；學(xué)歷對(duì)研究生信息行為的影響強(qiáng)于前者,但也主要影響研究生的信息利用行為；較之前兩者,專業(yè)和高校對(duì)對(duì)研究生檢索方式的選擇存在顯著影響,對(duì)其它三種信息行為也具有一定的影響；任務(wù)復(fù)雜度對(duì)研究生的信息檢索途徑和信息利用行為有顯著影響。論文主要分為三大部分,由七個(gè)章節(jié)構(gòu)成：第一部分,包括第一章和第二章。對(duì)國(guó)內(nèi)外相關(guān)研究進(jìn)行綜述,形成本研究的理論基礎(chǔ)。綜述文獻(xiàn)主要針對(duì)任務(wù)復(fù)雜度、信息行為及其影響因素,梳理了信息行為和任務(wù)復(fù)雜度相關(guān)理論,界定了本文中研究生信息行為、個(gè)體特征和任務(wù)復(fù)雜度等概念,確定了本文的研究思路。第二部分,包括第三章、第四章、第五章和第六章。該部分是本文的主體,探討了研究生信息行為的影響因素,很多學(xué)者研究發(fā)現(xiàn)性別、學(xué)歷等個(gè)體因素以及任務(wù)的復(fù)雜程度對(duì)個(gè)體的信息行為會(huì)產(chǎn)生影響,在此基礎(chǔ)上,提出了相關(guān)假設(shè),并且構(gòu)建了個(gè)體特征和任務(wù)復(fù)雜度對(duì)研究生信息行為的影響模型；設(shè)計(jì)了調(diào)查問(wèn)卷,發(fā)放對(duì)象是四所高校的在讀研究生,共收集到146份有效問(wèn)卷,對(duì)收集到的問(wèn)卷進(jìn)行信度檢驗(yàn)：統(tǒng)計(jì)分析了研究生信息行為的特征,利用SPSS和Lisrel軟件分析收集到的數(shù)據(jù),對(duì)研究假設(shè)進(jìn)行了驗(yàn)證,發(fā)現(xiàn)個(gè)體特征和任務(wù)復(fù)雜度都對(duì)研究生的信息行為存在一定的影響。第三部分,即第七章。對(duì)本文進(jìn)行了總結(jié),討論了本次研究有待完善的地方。提出后期研究可以從個(gè)體因素、環(huán)境因素和任務(wù)因素三個(gè)角度構(gòu)建一個(gè)系統(tǒng)的信息行為影響模型,指出可以將任務(wù)復(fù)雜度的研究拓展到其他群體的信息行為中。
[Abstract]:With the rapid development of the Internet, the amount of information increases exponentially. The massive literature resources provide support for scientific research activities, but also cause information overload.The research shows that graduate students spend a lot of time on information inquiry in scientific research activities, accounting for about half of the whole research process, so it is of great significance to study the information behavior of graduate students.By combing the existing research results, the thesis divides the individual characteristics of graduate students into four aspects: gender, major, academic background and university, and applies Robinson's theory of emotional cognition to judge the complexity of the task.According to the definition of information behavior of Wilson, the information behavior of graduate students is divided into four aspects: the way of information retrieval, the way of information retrieval, the exchange of information and the utilization of information.Based on this, the author builds a model of the influence of individual characteristics and task complexity on the information behavior of graduate students.This paper takes the graduate students of Nanjing University, Zhejiang University, Southeast University and Nanjing University of posts and Telecommunications as the research objects, and adopts the questionnaire (the main body of the questionnaire includes the individual characteristics of the graduate students).Task complexity judgment and postgraduates' information behavior are collected. Kendall correlation coefficient is used to study the influence of individual characteristics on graduate students' information behavior.The influence of task complexity on information behavior of graduate students is analyzed by using structural equation model.The results show that: gender has little effect on graduate students' information behavior, but only has a weak influence on the choice of graduate students' retrieval methods, education has a stronger impact on graduate students' information behavior than the former, but also mainly affects the information utilization behavior of graduate students.The thesis is divided into three parts, which are composed of seven chapters: the first part, including the first chapter and the second chapter.The related research at home and abroad is reviewed to form the theoretical basis of this study.Aiming at the task complexity, information behavior and its influencing factors, the literature reviews the related theories of information behavior and task complexity, and defines the concepts of information behavior, individual characteristics and task complexity of graduate students in this paper.The research idea of this paper is determined.The second part includes the third chapter, the fourth chapter, the fifth chapter and the sixth chapter.This part is the main body of this paper, discusses the influencing factors of information behavior of graduate students. Many scholars have found that gender, academic background and task complexity will have an impact on the information behavior of individuals.The related hypotheses are put forward, and the influence model of individual characteristics and task complexity on the information behavior of graduate students is constructed, and a questionnaire is designed, which is distributed to graduate students in four colleges and universities, and 146 valid questionnaires are collected.The reliability of the collected questionnaires is tested: the characteristics of information behavior of graduate students are statistically analyzed, and the data collected are analyzed by SPSS and Lisrel software, and the research hypotheses are verified.It is found that both individual characteristics and task complexity have a certain impact on the information behavior of graduate students.The third part is the seventh chapter.This article is summarized, and the research needs to be improved.It is put forward that a systematic information behavior influence model can be constructed from three aspects of individual factor, environment factor and task factor, and it is pointed out that the study of task complexity can be extended to the information behavior of other groups.
