中文摘要:
      信息源选择是信息搜寻领域的重要课题,自20世纪60年代以来受到广泛关注。随着互联网应用的深化,信息源的种类和数量不断增加,相关研究取得了颇为丰硕的成果。系统梳理已有研究成果,可为后续研究提供参考。本文从研究文献学科分布、核心概念及相关理论基础三个方面介绍国内外信息源选择的研究概况,从信息源、任务与环境、信息搜寻者主体等维度对影响信息源选择的理论要素进行全面综述,包括信息源的可获取性和质量,任务的复杂性、重要性与紧迫性,搜寻者的社会资本等,在此基础上构建了一个整合的信息源选择理论模型。文章最后对信息源选择的未来研究趋势进行展望,包括理论集成构建,研究对象群体的拓展,研究变量的细分与交叉,以及社会结构因素的纳入等。图3。表2。参考文献109。
英文摘要:

    As one of the most important research topics in information seeking field,information source selection has received much attention from scientific community since the 1960's. With the rapid growth of information technique,the increasing information sources is posing a new challenge for people to get information. Meanwhile,scientists have made many achievements about information source selection behavior for different kinds of people in the context of various information needs,tasks and situations. In order to provide a deeper understanding of information source selection,this paper summarizes the results of related studies and discusses potential extensions for future research.

    The literature search and review is based on the following databases:WileyInter Science,Elsevier Science Direct,Emerald Insight,Pro Quest Digital Dissertations & Theses,EBSCO Academic Search Premier,Springer LINK,The ACM Digital Library,Taylor & Francis,IEEE/IET Electronic Library and China Academic Journal Network Publishing Database. The search queries are “Information source selection”,“information source choice”,“information source preference” and “information source adoption”. The retrieval deadline is March 3rd,2016. Finally,we identified 299 English articles and 46 Chinese articles.

    This paper consists of four parts:an overview of related research,a review of theoretical factors,the model construction based on theories,and the discussion of future research. The first part is a general overview,which finds most studies of information source selection are in Information Science and Medical Science,while a small amount is distributed in management,education,communication,sociology,psychology and other fields;the main theoretical basis includes value comparison (such as Principles of Least Effort,Cost-Benefit Theory,Expectancy-Value Theory and Media Richness Theory),resource conditions (such as Social Capital Theory) and social psychology (such as Social Presence Theory and Transactive Memory Theory). From three major aspects (source-related,characteristics of searching task,and individual-related),the second part reviews the theoretical factors influencing the selection of information source,such as information source accessibility,information quality,task complexity,task importance,task urgency,social capital and so on. The third part is model construction. We build a comprehensive theoretical model of information source selection based on the related literature. The fourth part addresses some considerations and suggestions for future research. We propose that multi-subjects amalgamation can help strengthen the construction of a concept system and a theoretical framework. Furthermore,future studies should extend the types of research objects and refine the context variables. At last,we find it is necessary to study the influence of modern social structure and social factors on the selection of information source for different social groups.

    The major contribution of this paper is the proposition of a comprehensive theoretical model of information sources selection. In this model,information searchers and information sources are located in a semi-closed inner ring,while tasks and environment are respectively located in the periphery at both ends. That is,searchers make a perception and judgment on the accessibility and quality of information sources individually and return the results to themselves;the tasks can drive the searchers directly and reconstruct the relationship between the actors in the inner ring;the environment has external effect on the tasks,drives the searchers indirectly and shapes the searchers preferences for the information sources. This model can help us to understand the users information behavior and have some practical implications for information service and information resource construction. 3 figs. 2 tabs. 109 refs.
