+# ACCORD NLP
+
+ACCORD-NLP is a Natural Language Processing (NLP) framework developed by the [ACCORD](https://accordproject.eu/) project to facilitate Automated Compliance Checking (ACC) within the Architecture, Engineering, and Construction (AEC) sector.
+It consists of several pre-trained/fine-tuned machine learning models to perform the following information extraction tasks from regulatory text.
+1. Entity Extraction/Classification (ner)
+2. Relation Extraction/Classification (re)
+
+## Installation
+
+### From Source
+```
+git clone https://github.com/Accord-Project/accord-nlp.git
+cd accord-nlp
+pip install -r requirements.txt
+```
+
+### From pip
+```
+pip install accord-nlp
+```
+
+## Using Pre-trained Models
+
+### Entity Extraction/Classification (ner)
+
+```python
+from accord_nlp.text_classification.ner.ner_model import NERModel
+
+model = NERModel('roberta', 'ACCORD-NLP/ner-roberta-large')
+predictions, raw_outputs = model.predict(['The gradient of the passageway should not exceed five per cent.'])
+print(predictions)
+```
+
+### Relation Extraction/Classification (re)
+
+```python
+from accord_nlp.text_classification.relation_extraction.re_model import REModel
+
+model = REModel('roberta', 'ACCORD-NLP/re-roberta-large')
+predictions, raw_outputs = model.predict(['The <e1>gradient<\e1> of the passageway should not exceed <e2>five per cent</e2>.'])
+print(predictions)
+```
