This study introduces a novel express service defect evaluation model using text mining and machine learning. It identifies "responsiveness" as the key area for improvement in express service quality.
Area of Science:
- Service Science
- Data Mining
- Computational Linguistics
Background:
- Online customer feedback is crucial for service quality assessment.
- Existing methods may not fully capture the nuances of express service defects.
- A systematic approach is needed to analyze and prioritize service improvements.
Purpose of the Study:
- To construct a defect evaluation model for express services.
- To identify and prioritize key areas for service quality improvement.
- To provide actionable insights for enhancing customer satisfaction.
Main Methods:
- Web crawling to collect online negative comments.
- Support Vector Machine (SVM) for emotion analysis.
- Linear Discriminant Analysis (LDA) for topic modeling and characteristic word extraction.
- SERVQUAL and Importance-Performance Analysis (IPA) models for defect classification and mapping.
Main Results:
- Extracted characteristic words of express service defects using LDA.
- Classified defects based on SERVQUAL dimensions (tangibility, reliability, responsiveness, assurance, empathy, economy).
- Identified "responsiveness" as the primary improvement direction, followed by reliability, assurance, and economy.
Conclusions:
- The developed model offers valuable insights for evaluating service industry defects.
- Prioritizing "responsiveness" defects can significantly improve overall service quality.
- The model provides a framework for data-driven service enhancement.
