基于信息载体通信能力的知识服务模式分析 总被引：1，自引：0，他引：1
借鉴Proper和Bruza的信息栽体概念,从智力资源实体、虚拟资源实体、领域应用技术、协同服务技术等四个方面总结和分析现代知识服务模式.提出人和信息系统的"认知"能力主要表现为信息载体的通信能力;人作为智力资源实体提供知识服务,需要借助合适的协作机制设计将个体认知扩展为群体认知,使个体的服务转化为"系统"的服务;基于虚拟资源实体的知识模式、基于领域应用的知识服务模式和协同服务模式分别从智能代理技术、本体与语义网技术、协同服务技术三个层面提升信息系统的"认知"能力. 相似文献

Although information systems (IS) success has been given much attention in IS literature, failure has received lesser attention. This study empirically validates a model of digital service failure for consumers by integrating three dimensions from Tan’s failure model and one dimension from DeLone and Mclean’s Information Success model. The factors have been mapped to Expectation Disconfirmation Theory (EDT). Experiential survey approach has been used to collect primary data from information systems users who have experienced digital service failure. Structural equation modeling (SEM) has been used for model testing and validation to measure the impact of information, system, functional and service failure of digital service on end users. The findings suggests that information, functional, system and service failure has an impact on the consumers through the outcome, process, cost and user satisfaction of digital services. 相似文献

Many services can be self-provided. An individual user or a user firm can, for example, choose to do its own accounting - choose to self-provide that service - instead of hiring an accounting firm to provide it. Since users can ‘serve themselves’ in many cases, it is reasonable to suspect that they can also innovate with respect to the services they self-provide - possibly without the assistance of service providers.In this paper, we conduct the first quantitative exploration of the importance of services innovation by users, focusing on the field of commercial and retail banking services. We find that 55% of today's computerized commercial banking services were first developed and implemented by non-bank firms for their own use, and 44% of today's computerized retail banking services were first developed and implemented by individual service users rather than by commercial financial service providers. Manual precursors to these services - manual procedures that carried out functions similar to computerized services in our sample - were almost always developed by users as self-services.Our empirical findings differ significantly from prevalent producer-centered views of service development. We speculate that the patterns we have observed in banking with respect to the major role of users in service development will prove to be quite general. If so, this will be an important matter: on the order of 75% of GDP in advanced economies today is derived from services. We discuss the implications of our findings for research and practice in service development. 相似文献

With the advancement of mobile technologies, numerous web service providers have begun to extend their web services to the mobile context. To understand users’ mobile service adoption behaviour in the context of the web–mobile service transition, this study investigates the role of consistency between web and mobile services by proposing a typology of consistency and examining the extent to which and the boundary conditions under which consistency works. Specifically, consistency is classified into behavioural consistency (e.g., operational consistency) and object-based consistency, which includes consistency in information, system and service in terms of the information systems success model. We also contend the mediating effect of operational consistency and the interaction effect of trust in web services and operational consistency. A field survey with 235 mobile service users confirms our mediating and moderating hypotheses. The implications for theory and practice are also discussed. 相似文献

Measuring the success of mobile government (m-government) is a significant challenge faced by the public sector today, as governments are increasingly using mobile technology to provide public services to citizens and m-government endeavors have often fallen short of their potential. To address this gap, we draw on DeLone and McLean’s (2003) updated information systems (IS) success model in order to develop an m-government success model that theorizes service quality as comprising online and offline service quality and further uses perceived value to measure net benefits. The results of a survey of 286 m-government users in China indicate that information quality and online service quality, but not system quality, are positively associated with citizen satisfaction, which in turn is positively associated with perceived value. The results also show that the relationship between online service quality and citizen satisfaction is positively moderated by offline service quality, while citizen satisfaction partially mediates the relationships between information quality/online service quality (but not system quality) and perceived value. This study extends the updated IS success model by differentiating between online and offline service quality, as well as by introducing the notion of perceived value. Our results provide guidance to researchers and practitioners regarding the role of service quality and perceived value in measuring m-government system success. 相似文献
