Formalization and Goodness-of-Fit Analysis of Web Quality Model
Bo Zhao · Journal of Southwest Jiaotong University · 2012
In order to rationally standardize the proposed web quality model(WebQM) and verify the feasibility and effectiveness of the model in actual web quality assessment,WebQM was formalized in the ISO/IEC Z language and studied empirically based on the structural equation model(SEM) approach.By building a sample data set and constructing an SEM for WebQM,the goodness-of-fit of WebQM was analyzed based on the generalized least square method.Calculated GFI(goodness-of-fit index),AGFI(adjusted goodness-of-fit index) and CFI(comparative fit index) for actual sample data are 0.944,0.911 and 0.981,respectively.The result shows that WebQM highly conforms to the actual web source quality status and is feasible and effective.
