# FLAN-T5 small-GeoNames

This model is a fine-tuned version of [flan-t5-small](https://huggingface.co./google/flan-t5-small) on the GeoNames dataset.

## Model description

The model is trained to classify terms into one of 660 category classes related to geographical locations.

The model also works well as part of a Retrieval-and-Generation (RAG) pipeline by leveraging an external knowledge source, specifically [GeoNames Semantic Primes](https://huggingface.co./datasets/HannaAbiAkl/geonames-semantic-primes).

## Intended uses and limitations

This model is intended to be used to generate a type (class) for an input term.

# Training and evaluation data

The training and evaluation data can be found [here](https://github.com/HamedBabaei/LLMs4OL-Challenge-ISWC2024/tree/main/TaskA-Term%20Typing/SubTask%20A.2%20(FS)%20-%20GeoNames).

The train size is 8078865.

The test size is 702510.

## Example

Here's an example of the model capabilities:

- **input:**
  - *Lexical Term L:* Pic de Font Blanca

- **output:**
  - *Type:* peak

- **input:**
  - *Lexical Term L:* Roc Mele

- **output:**
  - *Type:* mountain

- **input:**
  - *Lexical Term L:* Estany de les Abelletes

- **output:**
  - *Type:* lake
