Background:

• Long non-coding RNA (lncRNA)-protein interactions are vital for cellular functions.
• Experimental methods for mapping these interactions are often laborious and costly.
• Developing efficient computational prediction tools is a significant need in the field.

Purpose of the Study:

• To compare LncPNet against existing state-of-the-art prediction methods.

Main Methods:

• LncPNet utilizes an embedded lncRNA-protein heterogeneous network for interaction prediction.
• The method was tested on datasets from the NPInter database.
• Performance was assessed using accuracy and Area Under the ROC Curve (AUC).

Main Results:

• LncPNet demonstrated high predictive performance with an accuracy of 0.930 and an AUC of 0.971.
• The method outperformed eight other state-of-the-art computational approaches.
• The heterogeneous network embedding approach proved effective for prediction.

Conclusions:
