# LLM4POI

## Dataset Summary

A preprocessed version of [LLM4POI](https://github.com/neolifer/LLM4POI), including the FourSquare-NYC, Gowalla-CA, and FourSquare-TKY datasets. Please refer to their repository for more details.

LLM4POI frames next POI prediction task into a question-answering problem that is fed as prompt into a large language model (LLM). The model is trained to generate the next POI given the current trajectory and the historical trajectory. This repository hosts both the Q&A version and the raw txt and csv versions of the datasets.

This dataset is used to train GenUP models as described in our paper [GenUP: Generative User Profilers as In-Context Learners for Next POI Recommender Systems](https://arxiv.org/abs/2410.20643).

### Data Instances

An example of a line in `test_qa_pairs_kqt.txt`:

```plaintext
<question>: The following data is a trajectory of user 2: At 2010-09-25 01:38:14, user 2 visited POI id 247 which is a Stadium and has Category id 261. At 2010-09-25 02:11:34, ... Given the data, At 2010-09-25 20:34:27, Which POI id will user 2 visit? Note that POI id is an integer in the range from 0 to 9690.<answer>: At 2010-09-25 20:34:27, user 2 will visit POI id 6350.
```

An example of a JSON object in `train_qa_pairs_kqt.json`:
