Background:

Traditional recommender systems struggle with data sparsity and the cold-start problem.
Extracting rich user and item features from textual data remains a challenge.

Purpose of the Study:

To propose Deep Semantic Mining based Recommendation (DSMR) for more accurate feature extraction.
To improve recommendation performance by addressing data sparsity and item cold-start issues.

Main Methods:

Utilizing BERT for deep semantic mining of review texts and item descriptions.
Employing a forward LSTM to capture temporal user preference dynamics.
Implementing a balanced data sampling strategy during model training for robustness.

Main Results:

DSMR achieved at least 11.95% lower average root mean square error (RMSE) than rating-based models.
DSMR outperformed three state-of-the-art review-text-based models, with an average RMSE 5.1% lower than the best performing model.

Conclusions:

Deep Semantic Mining based Recommendation (DSMR) effectively enhances recommender systems.
The model demonstrates superior performance in accuracy and robustness over existing methods.
