# roberta-es-clinical-trials-ner |
|
|
|
This medical named entity recognition model detects 4 types of semantic groups from the Unified Medical Language System (UMLS) (Bodenreider 2004): |
|
- ANAT: body parts and anatomy (e.g. *garganta*, 'throat') |
|
- CHEM: chemical entities and pharmacological substances (e.g. *aspirina*,'aspirin') |
|
- DISO: pathologic conditions (e.g. *dolor*, 'pain') |
|
- PROC: diagnostic and therapeutic procedures, laboratory analyses and medical research activities (e.g. *cirugía*, 'surgery') |
|
|
|
The model achieves the following results on the evaluation set: |
|
- Loss: 0.1580 |
|
- Precision: 0.8495 |
|
- Recall: 0.8806 |
|
- F1: 0.8647 |
|
- Accuracy: 0.9583 |

## Model description |
|
|
|
This model adapts the pre-trained model [bsc-bio-ehr-es](https://huggingface.co/PlanTL-GOB-ES/bsc-bio-ehr-es), presented in [Pio Carriño et al. (2022)](https://aclanthology.org/2022.bionlp-1.19/). |
|
It is fine-tuned to conduct medical named entity recognition on Spanish texts about clinical trials. |
|
The model is fine-tuned on the [CT-EBM-SP corpus (Campillos-Llanos et al. 2021)](https://bmcmedinformdecismak.biomedcentral.com/articles/10.1186/s12911-021-01395-z). |

## Training and evaluation data |
|
|
|
The data used for fine-tuning is the [Clinical Trials for Evidence-Based-Medicine in Spanish corpus](http://www.lllf.uam.es/ESP/nlpdata/wp2/). |
|
|
|
It is a collection of 1200 texts about clinical trials studies and clinical trials announcements: |
|
- 500 abstracts from journals published under a Creative Commons license, e.g. available in PubMed or the Scientific Electronic Library Online (SciELO) |
|
- 700 clinical trials announcements published in the European Clinical Trials Register and Repositorio Español de Estudios Clínicos |

## Environmental Impact |
|
|
|
Carbon emissions are estimated with the [Machine Learning Impact calculator](https://mlco2.github.io/impact/#compute) by [Lacoste et al. (2019)](https://arxiv.org/abs/1910.09700). The carbon impact is estimated by specifying the hardware, runtime, cloud provider, and compute region. |
|
|
|
- Hardware Type: 1 GPU 24 GB RTX 3090 |
|
- Time used: 4' (0.07 hours) |
|
- Compute Region: Spain, Europe |
|
- Carbon Emitted (Power consumption x Time x Carbon produced based on location of power grid): 0.01 kg eq. CO2 |
|
(Carbon offset: 0) |
