Hey There, crosati, welcome to the community

In Palantir Foundry, PDF text extraction can be achieved using various models and tools, including:

1. **Optical Character Recognition (OCR) Tools**:

- **Tesseract** : An open-source OCR engine that can be integrated into Foundry pipelines to extract text from scanned PDF documents.
- **AWS Textract** : A service that extracts text and data from scanned documents, which can be used within Foundry.

1. **Natural Language Processing (NLP) Models**:

- **SpaCy** : An NLP library for processing and analyzing extracted text, offering features like tokenization and named entity recognition.
- **BERT** : A transformer-based model for tasks like entity recognition or text classification.

1. **Custom Machine Learning Models** :

- Train custom models using Foundry’s machine learning capabilities for specific text extraction tasks.

1. **Foundry’s Data Integration and Processing Tools** :

- Use Foundry’s tools to preprocess PDFs, apply OCR, and analyze text as part of a data pipeline.

You can choose the model you want to use with the LLM node.
