Table 12
A performance comparison of our method with previous research, regarding single-label and multilabel identification.
| Studies | Algorithm | HF accuracy | AC accuracy | Remark |
| Shi et al. [4] | Naive Bayes | 73.2% | 81.1% | This study targets HF and AC only | Hoeffding tree | 74.9% | 87.0% | OzaBagADWIN | 76.5% | 88.3% | Our study | LSTM without fine-tuned language model | 84.8% | 85.1% | Our study achieves a better result regarding HF and can identify four more factors | LSTM with fine-tuned language model | 88.1% | 87.0% |
| Studies | Algorithm | Hamming loss | score | Remark |
| Robinson [13] | Latent semantic analysis | 0.269 | 0.409 | Impractically targeting 16 factors | Our study | LSTM without fine-tuned language model | 0.135 | 0.628 | Our study feasibly targets the six most frequent factors with promising results achieved | LSTM with the fine-tuned language model | 0.091 | 0.763 |
