This diagram illustrates the seven-step process adopted for the quantitative solution to text evaluation, from initial word segmentation to final school ranking. Each step is crucial for transforming raw textual data into meaningful, actionable insights for educational institutions.
Improved Dictionary Relevance
The selection of the "Extreme Value Table of Chinese Emotional Words of Tsinghua University" proved critical due to its high correlation with the target corpus.
0.184 Relevance with corpus dictionaryThis strong relevance indicates the dictionary's effectiveness in capturing the nuanced sentiment within the educational evaluation texts, laying a robust foundation for accurate sentiment analysis and quantification.
| Evaluation Metric | Algorithm Scoring | AI Evaluation |
|---|---|---|
| Excellent/Good Grade Combined | 35% | 94% |
| Overlapping (Excellent/Good) | 81% (Sentiment & SnowNLP) | 37% (AI & Sentiment) |
| AI 'Excellent' in Total Sample | N/A | 61% |
| Overlapping (Sentiment Dict. & SnowNLP, 'Excellent') | 76% | N/A |
A comparative analysis reveals both alignment and discrepancies between algorithmic and AI-based sentiment scoring. While AI shows a high proportion of excellent/good grades, the algorithm, especially when combining sentiment dictionary and SnowNLP, offers a more nuanced discrimination that aligns better with general teaching evaluation experiences, indicating a need for a balanced approach.
Impact on Education Evaluation
Problem: Lack of quantitative application cases for educational text evaluation, leaving valuable teacher comments underutilized.
Solution: Development of a dictionary-based sentiment analysis method, enhanced with AI text analysis, to quantify student comprehensive quality evaluations from 18 secondary vocational schools in Shanghai.
Outcome: This method transformed previously idle textual teacher evaluations into actionable data, providing final scores and ranking suggestions. Initial analysis showed a 15% difference between the algorithm and AI, highlighting the iterative refinement for improved accuracy and utility. This approach significantly enhances the efficiency and effectiveness of data usage in educational evaluation.
