Google Cloud Document AI Samples

Overview

The repository contains samples and Community Samples that demonstrate how to analyze, classify and search documents using Google Cloud Document AI.

Samples

• Apps Script & Google Drive Integration: Code in Google Apps Script for integration with Document AI.
• Document AI Warehouse Processing (Python): This project demonstrates how to perform common actions on Document AI Warehouse through API.
• Document AI Warehouse Batch Ingestion via script: This project is a helper utility to do batch ingestion of the documents into the Document AI Warehouse.
• BQ Connector: This project uses the Document AI API to process a document, format the result and save it into a BigQuery table.
• Content Moderation with Dialogflow CX: This project uses the Content Moderation processor with Dialogflow CX for toxicity routing during a conversation.
• Filter HITL Language: This project uses the languages detected by Document AI (post-HITL) to sort the Document.json files into separate Cloud Storage buckets.
• Fraud Detection: This project uses the Document AI Invoice Parser with EKG and Google Maps to store document Entities in BigQuery.
• JSON Explorer: A React Tool to explore the Document JSON Response.
• Language Extraction: This project uses the Document AI API to detect the languages in a multi-page document.
• Paper Summarization: This project uses the Document AI API to summarize scientific articles.
• PDF Embedded Text: Demonstrates how to use the Native PDF parsing feature for the OCR Processor (v1beta3)
• SQL over Docs: This project shows how to run a BigQuery SQL and extract information from documents.
• Tax Processing Pipeline: This project uses the Document AI API to classify, parse, and calculate a tax form using multiple document types.
• Web App Demo: This project is a full-stack application that uses Document AI to process different types of documents. This application currently supports Form, Invoice and OCR processors.
