This model is a BERT-based Location Mention Recognition model that is adopted from the [TLLMR4CM GitHub](https://github.com/rsuwaileh/TLLMR4CM/). The model identifies the toponyms' spans in the text without predicting their location types. 

The model is trained using the training splits of all events from [IDRISI-R dataset](https://github.com/rsuwaileh/IDRISI) under the `Type-less` LMR mode and using the `Random` version of the data. You can download this data in `BILOU` format from [here](https://github.com/rsuwaileh/IDRISI/tree/main/data/LMR/AR/gold-random-bilou/). All Location types in the data were normalized to the `LOC` tag. More details are available [here](https://github.com/rsuwaileh/IDRISI/tree/main/models). More details about the models are available [here](https://github.com/rsuwaileh/IDRISI/tree/main/models).
