Exploring factors affecting Chinese consumers' usage of short message service for personal communication

Abstract. Short message service (SMS) is very popular in China. While many reports indicate that the SMS market has great potential, little is known about why people adopt SMS. This study uses the technology acceptance model and network externalities to examine the factors influencing the adoption of SMS for personal communication in China. Using data collected from 262 mobile phone users, we find that perceived usefulness, perceived enjoyment and perceived service cost affect SMS use. Perceived network externalities also contribute to higher perceived usefulness and perceived ease of use and affect SMS adoption. The results provide insight to SMS marketing strategies.     

Essential SMSs: developing a service management scheme for semiconductor factory management systems

A semiconductor factory contains hundreds of pieces of equipment. More reliable service by equipment managers is required to increase the utilization of equipment and improve product quality and yield. Therefore, developing a reliable service management scheme (SMS) for semiconductor factory management systems is essential. This study presents an SMS that applies Jini Technology and uses the design by contract technologies. The SMS has error-detecting and function-replacing capabilities. The SMS detects the malfunctioning of an equipment manager (service) and sends an event notice to the factory manager. The GEV in the SMS archives the credit values of all of the equipment managers so that the factory manager can select better equipment managers for service by checking their credit values. The illustrative example and the evaluation of the reliability improvement reveal that the proposed SMS provides an efficient, reliable, fault tolerant, and cost-effective mechanism for semiconductor factory management systems. Lastly, this illustrative example is successfully implemented and demonstrated and the core technology of SMS is transferred to and commercialized by Charming Systems Corporation.

Service Quality and Perceived Value's Impact on Satisfaction, Intention and Usage of Short Message Service (SMS)

SMS, being an almost instantaneous communication medium that connects people, is now a phenomenon that has grown and spread around the globe at an amazing speed. Given the current trend of SMS usage and its potential growth, this paper will provide an insight of the extent to which how service quality and the value perceived by the SMS users have an impact on their extent of the SMS usage in the post SMS adoption phase. Specifically, this article will examine how service quality of the service providers and perceived value affect customer satisfaction and how customer satisfaction will affect their behavioural intention to continue to use SMS which in turn affects the extent of SMS usage in the local context. Using partial-least-squares, an analysis was conducted based on the 150 surveys collected to test for the proposed relationships. The results showed that the tangibles, empathy and assurance dimensions of service quality are antecedents of customer satisfaction and a positive relationship exists between customer satisfaction and customers' behavioural intentions to continue to use SMS. Additionally, the positive relationship between customers' behavioural intentions to continue to use SMS and the extent of SMS usage is also significant. These results were similar to the results shown by Cronin and Taylor (1992) studies. The perceived value/customer satisfaction relationship investigated in this research was in line with Fornell et al.(1996) and Cronin et al.(2000) where perceived value was one of the determinants of customer satisfaction. Specially, the results revealed that perceived value, together with tangibles, empathy and assurance aspects of the service quality, played an important role in determining customer satisfaction for SMS. Implications of the above results for research and practice are discussed.     

An interactive mobile SMS confirmation method using secret sharing technique

As we all know, Short Message Service (SMS) has brought about junk emails or nonsense messages coming from advertisement providers, called SMS spam. It does bother subscribers and make them distress to check SMS messages of mobile system. Statistically, each mobile subscriber receives an average number of 8.29 short messages every week. Thus, to furnish legitimate message service to the mobile subscribers, engineers have strived to figure out an interactive service system which can certify the user-participation in a communicatory session. If a system can verify whether the communicating party is human being or not, the machine tries can be detected to mitigate the risk. To realize this essential, we aim to develop an interactive SMS confirmation mechanism using the famous techniques – CAPTCHA and secret sharing. Experimental results show that it takes slight computation costs to complete the authentication including the identity verification and the check of user-participation. This has led to predominance that the new method is suitable for mobile environment.     

Combining rule-based learning and memory-based learning for automatic word spacing in simple message service

Short message service (SMS) is a widely used service in modern mobile phones that allows users to send or receive short text messages. Current SMS, however, has two problems of inconvenient input and short message length. These problems can be resolved if a phone has an ability of automatic word spacing. This is because users need not put spaces in sending messages and longer messages are possible as they contain no space. Thus, automatic word spacing will be a very useful tool for SMS, if it can be commercially served. The practical issues of implementing it on the devices such as mobile phones are small memory and low computing power of the devices. To tackle these problems, this paper proposes a combined model of rule-based learning and memory-based learning. According to the experimental results, the model shows higher accuracy than rule-based learning or memory-based learning alone. In addition, the generated rules are so small and simple that the proposed model is appropriate for small memory devices.
