多重因素综合的P2P网络信任评估模型研究     

张祖昶  王诚 《环球赛鸽科技》2013,(24)

在交易评估机制中,信任度是根据个体交易的历史信息,由多重因素综合而成。这些因素在评估机制中均有作用和影响,但由于各个因素自身的特点,其作用和影响大小不一。本文由此提出了一种多重因素综合的 P2P网络信任评估模型,给出了新的信任评估计算方法和仿真实验。实验结果表明,该评估模型效果显著。本文提出的信任评估模型是属于对等信任模型,该模型适合P2P网络的特性。对于对等信任模型而言,其难点是如何建立起网络节点之间的信任关系,其优点是保持了P2P网络的特性。  相似文献   

文化遗产数字叙事信任模型:概念与框架     

王晓光  赵珂 《中国图书馆学报》2024,50(2):30-41

信任是数字环境下文化遗产数字叙事的基础。文化遗产数字叙事是一种具有重构和演绎特质的叙事方式,在数字化、数据化和艺术化阶段会产生不同的信任问题。作为一种特殊的信息系统,文化遗产数字叙事的人机交互特征体现出系统、信息和用户之间的相互连通和协同影响,系统叙事的可信度和用户体验的信任感构成了信任模型的双向动态互动,涉及文化遗产信息资源、叙事性架构、数字化呈现、系统本身的功能建设和知识服务,以及用户的意图和行动。文化遗产数字叙事信任模型不仅有助于提升文化遗产的数智化活化利用水平,促进对文化遗产信息资源的深度挖掘、叙事内容的创意演绎、文化内涵的有效阐释与呈现,而且有望为可信的文化遗产数字叙事提供理论和实践指导,助力文化遗产数字化转型发展。图3。参考文献46。  相似文献   

论证券投资基金的法律性质     

马凤春 《安阳师范学院学报》2009,(4):12-14,49

证券投资基金作为一种现代投资工具,其运作不能脱离制度的基本法理。证券投资基金是信托关系,但它对信托基本原理不只是单纯的遵循,同时更是一种具体运用和扩展。信托制度已由民事关系的“理财”制度向商事关系的“生财”制度转变,证券投资基金正是这种关系的体现。  相似文献   

The impact of trust and changes in trust: A national comparison of individual adoptions of information and communication technologies and related phenomenon     

Peeter Kirs  Kallol Bagchi 《International Journal of Information Management》2012

Trust has been shown to play an important role in the adoption of information and communication technology (ICT) on an individual and firm level, but has received relatively little attention on a national level. In this paper we examine the impact of generalized trust, as measured by the World Value Survey, on the adoption of ICT products and related phenomena (e.g., such issues as Telecommuting and services such as E-Government Readiness), at a national level, while controlling for a nation's wealth. Because national trust levels having changed over time, we also examine how the rate of change in trust has impacted the adoption of ICT and ICT related phenomenon. Our findings provide strong empirical support for the argument that trust impacts national level adoption. The results are robust as we consider multiple variables and data sources. We also show that changes in trust rates are generally associated with corresponding changes in ICT adoptions.  相似文献   

Exploring the impact of communication effectiveness on service quality,trust and relationship commitment in IT services     

Jungi Park  Jungwoo Lee  Hyejung Lee  Duane Truex 《International Journal of Information Management》2012

Most firms today are served by specialized IT service providers for the development and maintenance of their business information systems. During the IT service encounter, service providers and clients interact throughout the project, exchanging information, sharing knowledge and making critical decisions. From the IT service provider's viewpoint, it is important to raise the level of clients’ relationship commitment during this service encounter as their business continuity depends upon clients assessment. Intuitively, effective communication and effective service quality, mediated by trust, are critical factors in raising the level of relationship commitment. This study proposes an empirical model consisting of four critical antecedents of relationship commitment (communication effectiveness, technical service quality, functional service quality and trust) and then tests the model using data points solicited from two global firms. Study results revealed that trust is a strong mediator for relationship commitment while functional, rather than technical, service quality is a stronger mediator in forming the clients’ trust.  相似文献   

Examining the role of trust and quality dimensions in the actual usage of mobile banking services: An empirical investigation     

《International Journal of Information Management》2019

Mobile banking (m-banking) has emerged dynamically over the years due to consumers' increased use of mobile technologies, their ever-growing lifestyle choices and also the several different economic factors. This paper proposes a new research model by extending the DeLone & McLean information systems (D&M IS) success model to understand users’ actual usage of m-banking. The research model was tested and validated using data collected by survey from 227 Omani residents. This study employed a two-staged analytical approach by combining structural equation modeling and neural network analysis. The results divulge that satisfaction and intention to use stand as two important precedents of actual usage, and the satisfaction also mediates the relationship between service quality, information quality and trust with intention to use m-banking and negates with that of system quality. We have provided the theoretical as well as practical implications of the findings.  相似文献

Understanding trust influencing factors in social media communication: A qualitative study     

《International Journal of Information Management》2017,37(2):25-35

Based on five types of trust, this research explores trust influencing factors in peer-to-peer interpersonal communication, group communication and mass communication. Previous research has mainly focused on trust and the corresponding antecedents in electronic commerce communication and online collaboration. This study extends the literature on trust influencing factors in social media communication. A trust traffic light model is used to illustrate the importance of keywords, drawn from interviews with 115 participants who use WeChat frequently. Salient trust factors were found and further elaborated through qualitative analysis. Furthermore, we developed a trust cognitive onion model to illustrate the interactions of trust factors.  相似文献

王嘉昀  许洁 《中国科技期刊研究》2018,29(9):888-893

【目的】 从系统论视角出发,分析学术出版过程中出现的信任危机,提出应对危机的策略,从理论和技术上提高同行评审工作质量,提升同行评审的信任度。【方法】 以文献调查和案例分析为主要方法,综述已有的关于同行评审现状和问题研究以及信任危机的相关理论,结合案例,从社会、经济、文化等不同角度剖析同行评审体系存在信任危机的原因,最后针对同行评审体系的问题和各方面原因,结合目前国内外的创新尝试,提出应对策略。【结果】 社会转型时期,同行评审主体之间缺乏完全信任,传媒影响加剧了同行评审参与主体之间的信任危机,同行评审客观性与审稿人主观性之间矛盾不可调和使同行评审信任危机无法消除。【结论】 通过设立同行评审内部的监督机制、重视传媒影响、完善网络同行评审系统平台,巩固同行评审信任,促进学术出版的长远发展。  相似文献
