# SentenceTransformer based on sentence-transformers/all-MiniLM-L6-v2
This is a [sentence-transformers](https://www.SBERT.net) model finetuned from [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2). It maps sentences & paragraphs to a 384-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.
## Model Details
### Finetuning
The model was finetuned on [Coronavirus tweets NLP - Text Classification](https://www.kaggle.com/datasets/datatattle/covid-19-nlp-text-classification?select=Corona_NLP_train.csv). The objective was agrupate tweets by sentiment, for this, the dataset was divided into pairs of tweets and the similarity between them defined by the sentiment label. The following labels were used:
- Extremely Positive and Extremely Negative: 0.0
- Extremely Positive and Neutral: 0.2
- Extremely Positive and Positive: 0.7
- Extremely Positive and Negative: 0.2
- Extremely Negative and Neutral: 0.2
- Extremely Negative and Positive: 0.2
- Extremely Negative and Negative: 0.7
- Neutral and Positive: 0.5
- Neutral and Negative: 0.5
### Model Description
- **Model Type:** Sentence Transformer
- **Base model:** [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2)
- **Maximum Sequence Length:** 256 tokens
- **Output Dimensionality:** 384 tokens
- **Similarity Function:** Cosine Similarity
### Model Sources
- **Documentation:** [Sentence Transformers Documentation](https://sbert.net)
- **Repository:** [Sentence Transformers on GitHub](https://github.com/UKPLab/sentence-transformers)
- **Hugging Face:** [Sentence Transformers on Hugging Face](https://huggingface.co/models?library=sentence-transformers)
### Full Model Architecture
```
SentenceTransformer(
(0): Transformer({'max_seq_length': 256, 'do_lower_case': False}) with Transformer model: BertModel
(1): Pooling({'word_embedding_dimension': 384, 'pooling_mode_cls_token': False, 'pooling_mode_mean_tokens': True, 'pooling_mode_max_tokens': False, 'pooling_mode_mean_sqrt_len_tokens': False, 'pooling_mode_weightedmean_tokens': False, 'pooling_mode_lasttoken': False, 'include_prompt': True})
(2): Normalize()
)
```
## Usage
### Direct Usage (Sentence Transformers)
First install the Sentence Transformers library:
```bash
pip install -U sentence-transformers
```
Then you can load this model and run inference.
```python
from sentence_transformers import SentenceTransformer
# Download from the 🤗 Hub
model = SentenceTransformer("gianvr/sbert-tunned-covid")
# Run inference
sentences = [
'Governor Cuomo Please order retail businesses to close My husband has to go to work and expose himself to the virus Store owners will not close unless you tell them they have to I have two friends fighting for their lives PLEASE CLOSE STORES NOW',
'Clothier @LandsEnd has closed all of its retail stores through March 29th due to coronavirus pandemic. They will pay all of their employees during the time period.\r\r\n\r\r\nThis is their store at the Hunt Valley Towne Center. #HuntValley #coronavirus https://t.co/DIwNzAOLeb',
'Went to the store today. Most canned food is gone. We needed toilet paper and actually got a pack of 12 rolls. We got milk and cat treats as well. Thank god for Save on Foods for still having some stuff. \r\r\nOver 100 cases of Covid-19 in my province so panic buying is common.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]
# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
```
