An expert system approach to improving stability and reliability of web service

An empirical investigation of factors affecting ubiquitous computing use and U-business value

“…The system processing speed of ubiquitous computing is fast Adapted from Venkateswaran and Son (2007), Tseng and Wu (2007) Ubiquitous computing speed does not cause any inconvenience for use Adapted from Vaughan (2004), Venkateswaran and Son (2007) Ubiquitous computing responds immediately when I press enter or click the mouse Adapted from Vaughan (2004), Venkateswaran and Son (2007) Ubiquitous computing is stable Adapted from Vaughan (2004), Tseng and Wu (2007) Ubiquitous computing has no errors Adapted from Vaughan (2004), Tseng and Wu (2007) Ease of use Ubiquitous computing is user friendly Adopted from McHaney, Hightower, and Pearson (2002), Rai et al (2002), Khalil and Elkordy (2005) It is easy to use ubiquitous computing Adopted from McHaney et al (2002), Rai et al (2002), Legris, Ingham, and Collerette (2003), Khalil and Elkordy (2005), Hsieh and Wang (2007) It is not hard to use ubiquitous computing Adapted from Legris et al (2003), Khalil and Elkordy (2005), Hsieh and Wang (2007) Ubiquitous computing is convenient and easy to learn Adapted from Legris et al (2003), Khalil and Elkordy (2005), Hsieh and Wang (2007) (2004), Riekki et al (2006), Hsieh and Wang (2007) Information quality…”

Examining the Factors Affecting Perceived Enjoyment and Usage Intention of Ubiquitous Tour Information Services: A Service Quality Perspective

“…To claim discriminant validity, the square root of the AVE associated with a particular construct must be greater than its correlations with other constructs Janda et al (2002), Kim et al (2009), Szymanski and Hise (2000), Tseng and Wu (2007) Information quality † Offers accurate tour information † Offers various tours information † Offers detailed tour information † Offers information that the user needs Delone and McLean (2003), Janda et al (2002), Kim et al (2009), Li (1997, Li et al (2002), Rai et al (2002) Interface design † Easy to read and view the main menu screen † Refined screen design † Overall coordination of images on device screen † Appropriate color and image of device screen Gounaris et al (2007), Szymanski and Hise (2000) Convenience † Simplicity of instrument operation † Save time and effort in conducting operation † Easy navigation of instrument operation Carlson and O'Cass (2010), Kim et al (2009), Rai et al (2002, Teo et al (1999) Perceived enjoyment † It was enjoyable to use it † It was interesting to use it † It was bothersome to use it Davis et al (1992), Koufaris (2002), Teo et al (1999) Usage intention † Users are satisfied with the use of the device † User will recommend its use to others † User will use this kind of tour information service instrument in the future Carlson and O'Cass (2010), DeLone and McLean (2003), Gounaris et al (Fornell & Larcker, 1981). According to the estimates presented in Table 5, each construct sufficiently differed from the other constructs, and, therefore, the measures represented discriminant validity.…”

A Fuzzy Model for Selecting Social Web Services

“…The overall service quality is determined by combining several subjective customers' perception towards each of the evaluated criteria. In [17], Tseng and Wu propose a fuzzy expert system to monitor the performance of Web services. The system detects and resolves potential problems that might affect Web services performance in order to improve their stability and reliability.…”
