+
+## 📊 Dataset
+
+NCBI Disease corpus is a comprehensive resource for disease name recognition and concept normalization.
+
+The NCBI Disease corpus is a gold-standard dataset containing 793 PubMed abstracts with 6,892 disease mentions mapped to 790 unique disease concepts from Medical Subject Headings (MeSH) and Online Mendelian Inheritance in Man (OMIM). Developed by the National Center for Biotechnology Information, this corpus provides both mention-level and concept-level annotations for disease entity recognition and normalization. The dataset is extensively used for developing clinical NLP systems, medical diagnosis support tools, and biomedical text mining applications. It serves as a critical benchmark for evaluating disease name recognition systems in healthcare informatics and medical literature analysis.

+
+## 🚀 Quick Start
+
+### Installation
+
+```bash
+pip install transformers torch
+```
+
+### Usage
+
+```python
+from transformers import pipeline
+
+# Load the model and tokenizer
+# Model: https://huggingface.co/OpenMed/OpenMed-NER-PathologyDetect-BigMed-560M
+model_name = "OpenMed/OpenMed-NER-PathologyDetect-BigMed-560M"
+
+# Create a pipeline
+medical_ner_pipeline = pipeline(
+    model=model_name,
+    aggregation_strategy="simple"
+)
+
+# Example usage
+text = "Early detection of breast cancer improves survival rates."
+entities = medical_ner_pipeline(text)
+
+print(entities)
+
+token = entities[0]
+print(text[token["start"] : token["end"]])
+```
+
+NOTE: The `aggregation_strategy` parameter defines how token predictions are grouped into entities. For a detailed explanation, please refer to the [Hugging Face documentation](https://huggingface.co/docs/transformers/en/main_classes/pipelines#transformers.TokenClassificationPipeline.aggregation_strategy).
+
+Here is a summary of the available strategies:
+- **`none`**: Returns raw token predictions without any aggregation.
+- **`simple`**: Groups adjacent tokens with the same entity type (e.g., `B-LOC` followed by `I-LOC`).
+- **`first`**: For word-based models, if tokens within a word have different entity tags, the tag of the first token is assigned to the entire word.
+- **`average`**: For word-based models, this strategy averages the scores of tokens within a word and applies the label with the highest resulting score.
+- **`max`**: For word-based models, the entity label from the token with the highest score within a word is assigned to the entire word.
+
+### Batch Processing
+
+For efficient processing of large datasets, use proper batching with the `batch_size` parameter:
+
+```python
+texts = [
+    "Early detection of breast cancer improves survival rates.",
+    "The patient exhibited symptoms consistent with Parkinson's disease.",
+    "Genetic testing revealed predisposition to Huntington's disease.",
+    "Malaria is a life-threatening disease caused by parasites transmitted through mosquito bites.",
+    "Multiple sclerosis affects the central nervous system, leading to a range of symptoms.",
+]
+
+# Efficient batch processing with optimized batch size
+# Adjust batch_size based on your GPU memory (typically 8, 16, 32, or 64)
+results = medical_ner_pipeline(texts, batch_size=8)
+
+for i, entities in enumerate(results):
+    print(f"Text {i+1} entities:")
+    for entity in entities:
+        print(f"  - {entity['word']} ({entity['entity_group']}): {entity['score']:.4f}")
+```
+
+### Large Dataset Processing
+
+For processing large datasets efficiently:
+
+```python
+from transformers.pipelines.pt_utils import KeyDataset
+from datasets import Dataset
+import pandas as pd
+
+# Load your data
+# Load a medical dataset from Hugging Face
+from datasets import load_dataset
+
+# Load a public medical dataset (using a subset for testing)
+medical_dataset = load_dataset("BI55/MedText", split="train[:100]")  # Load first 100 examples
+data = pd.DataFrame({"text": medical_dataset["Completion"]})
+dataset = Dataset.from_pandas(data)
+
+# Process with optimal batching for your hardware
+batch_size = 16  # Tune this based on your GPU memory
+results = []
+
+for out in medical_ner_pipeline(KeyDataset(dataset, "text"), batch_size=batch_size):
+    results.extend(out)
+
+print(f"Processed {len(results)} texts with batching")
+
+```
+
+### Performance Optimization
+
+**Batch Size Guidelines:**
+- **CPU**: Start with batch_size=1-4
+- **Single GPU**: Try batch_size=8-32 depending on GPU memory
+- **High-end GPU**: Can handle batch_size=64 or higher
+- **Monitor GPU utilization** to find the optimal batch size for your hardware
+
+**Memory Considerations:**
+```python
+# For limited GPU memory, use smaller batches
+medical_ner_pipeline = pipeline(
+    model=model_name,
+    aggregation_strategy="simple",
+    device=0  # Specify GPU device
+)
+
+# Process with memory-efficient batching
+for batch_start in range(0, len(texts), batch_size):
+    batch = texts[batch_start:batch_start + batch_size]
+    batch_results = medical_ner_pipeline(batch, batch_size=len(batch))
+    results.extend(batch_results)
+```
