Analyzing E-Commerce Websites: A Quali-Quantitive Approach for the User Perceived Web Quality (UPWQ)
Bibliographic record
Abstract
The electronic commerce (e-commerce) is an increasingly important phenomenon and this research deals with perceived quality from the users-customers point of view. The aim of this paper is to shed light on the critical factors determining the User Perceived Web Quality (UPWQ) for e-commerce. We use the Pareto Chart as qualitative methodology able to identify the UPWQ considering not only technical features (ease of use, design, smart phone and tablet responsivity, information), but also emotional features such as trust, empathy, free shipping and discount. The Pareto chart main has the advantage to classify the selected features by their relevance. We found that emotional features are more relevant than technical ones. Among the features we took into account, three alone (discount, free shipping and ease of use) determine about 70% of the user perceived web quality for e-commerce. Our results have significant practical implication for managers involved in online business in order to better allocate resources to the most critical factors.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
