In order to correctly evaluate semantic technologies, which have become widely adopted in recent years, we need to put evaluations under the scope of a unique software quality model. This paper presents a quality model for semantic technologies. First, some well-known software quality models are described, together with methods for extending them. Afterwards, a new method for extending quality ...

The study statistically tests the proposition of the ISO/IEC 9126 standard that higher external quality (quality when software is executed) implies higher ‘quality in use’. For this purpose, the study based on 75 user survey data shows that individual external quality subcharacteristics are positively associated with user satisfaction as defined in ‘quality in use’. This study also investigates...

This paper discusses a methodological approach to define quality models (QM) for Web sites of any kind, including Web 2.0 sites. The approach stresses the practical use of a QM, in requirement definition and quality assessment, during design & development processes or during site operation. An important requirement for such QMs is organization mapping, which allows who is in charge of quality m...
