Knowledge Prompting for Point of Interest (POI) Recommendation (KP4POI)

This project builds upon KP4SR, which serves as our baseline model.

1. Clone KP4SR into this directory.
2. Replace the corresponding files in the scripts and src directories with those provided here.

Knowledge Prompts for POI Recommendation

• Masked Personalized Prompt
• Venue Knowledge Prompt
• User Knowledge Prompt

---

Data Preprocessing

1. Convert the original data and add additional information.
   • See the README in the preprocess directory.
2. Prepare the data required by KP4SR.
   • See the README in the data directory for experimental setup.

Model Training and Testing

Once the data are prepared, run:

bash run_poi.sh
