+# 🌟 EntityBERT-NER Model 🌟
+
+## 🚀 Model Details
+
+### 🌈 Description
+The `boltuix/EntityBERT-NER` model is a fine-tuned transformer for **Named Entity Recognition (NER)**, built on the lightweight `boltuix/bert-mini` base model. It excels at identifying 36 entity types, including people, locations, organizations, dates, times, phone numbers, emails, URLs, and more, in English text. Designed for efficiency and high accuracy, it’s perfect for real-time applications like information extraction, chatbots, and knowledge graph construction across domains such as travel, medical, logistics, and education.

+
+## 🎯 Use Cases for NER
+
+### 🌟 Direct Applications
+- **Information Extraction**: Extract entities like 👤 PERSON (e.g., "Dr. Sarah Lee"), 🌍 LOCATION (e.g., "Baltimore"), 🗓️ DATE (e.g., "July 10, 2025"), and 📞 PHONE_NUMBER (e.g., "+1-410-955-5000") from travel itineraries, medical reports, or logistics documents.
+- **Chatbots & Virtual Assistants**: Enhance user interactions by recognizing entities in queries like "Book a flight from Dubai to Tokyo on October 10, 2025."
+- **Search Enhancement**: Enable semantic search with entity-based indexing, e.g., finding documents mentioning "Emirates" or "Shibuya Crossing."
+- **Knowledge Graphs**: Build structured graphs linking entities like 🏢 ORGANIZATION (e.g., "Johns Hopkins") and 📍 ADDRESS (e.g., "1800 Orleans St").
+
+### 🌱 Downstream Tasks
+- **Travel NLP**: Extract travel details like departure/arrival times and transportation modes (e.g., "flight," "train") for booking systems.
+- **Medical NLP**: Identify doctors, hospitals, and contact info in patient records or consultation requests.
+- **Logistics NLP**: Track shipments by extracting locations, dates, and company names (e.g., "FedEx," "DHL").
+- **Education NLP**: Parse academic events, university names, and contact details from seminar announcements.

+
+## 🛠️ Getting Started
+
+### 🧪 Inference Code
+Use the model for NER with the following Python code:
+
+```python
+from transformers import AutoTokenizer, AutoModelForTokenClassification, pipeline
+
+# Load model and tokenizer
+tokenizer = AutoTokenizer.from_pretrained("boltuix/EntityBERT-NER")
+model = AutoModelForTokenClassification.from_pretrained("boltuix/EntityBERT-NER")
+
+# Create NER pipeline
+nlp = pipeline("token-classification", model=model, tokenizer=tokenizer)
+
+# Input text
+text = "Dr. Sarah Lee at Johns Hopkins, Baltimore, MD, books a flight to Rochester, MN on July 10, 2025, contact +1-410-955-5000 or [email protected], visit www.airmed.com."
+
+# Run inference
+ner_results = nlp(text)
+
+# Print results
+for entity in ner_results:
+    print(f"{entity['word']:15} → {entity['entity']}")
+```
+
+### ✨ Example Output
+```
+Dr.             → B-PERSON
+Sarah           → I-PERSON
+Lee             → I-PERSON
+Johns           → B-ORGANIZATION
+Hopkins         → I-ORGANIZATION
+Baltimore       → B-fromloc.city_name
+MD              → B-fromloc.state_name
+Rochester       → B-toloc.city_name
+MN              → B-toloc.state_name
+July            → B-DATE
+10              → I-DATE
+2025            → I-DATE
++1-410-955-5000 → B-PHONE_NUMBER
+sarah.lee       → B-EMAIL
+@jhmi.edu       → I-EMAIL
+www.airmed.com  → B-URL
+```
+
+### 🛠️ Requirements
+```bash
+pip install transformers torch pandas pyarrow
+```
