Action Table - Document

Summarize news with JamAI Base

1. Introduction

This tutorial will guide you through using the JamAI Base Python SDK to create a simple news summarization system.

What We'll Build

Get a news and let AI tells you the main message!

In this tutorial, we'll create a news summarization system that:

Takes a news document as input. The supported formats include: .csv, .tsv, .txt, .md, .doc, .docx, .pdf, .ppt, .pptx, .xls, .xlsx, .xml, .html, .json, .jsonl.
Upload the document to JamAI Base action table.
Obtain the key information like:
- Summary
- Tag

Prerequisites

Before starting, you'll need:

Python 3.11 or higher installed
Project ID and Personal Access Token (PAT)

2. Installation and Setup

Installing the Python SDK

pip install jamaibase

Basic Configuration

Get your Personal Access Token (PAT) here:

Get your Project ID here:

from jamaibase import JamAI, types as t

PROJECT_ID = "your_project_id"
PAT = "your_PAT"

client = JamAI(
    project_id=PROJECT_ID,
    token=PAT
)

You can use a .env file to manage your PROJECT_ID and PAT.

3. Creating Your Action Table

For simplicity, you can set up your action table in the JamAI Base platform:

Navigate to your JamAI Base action table tab
Create a new action table named "news_summarization"

Create the following columns:

Name

Column Type

Data Type

document

Input

Document

summary

LLM Output

Text

tag

LLM Output

Text

Update the Prompt as LLM Output columns as follows:

Column name

Prompt

summary

Table name: "news_summarization"

document: ${document}

Summarize the article in not more than three sentences and not more than 50 words.

Provide the summary in the number form.

Be factual and do not hallucinate. Remember to act as a cell in a spreadsheet and provide concise, relevant information without explanations unless specifically requested.

tag

Table name: "news_summarization"

document: ${document}

Provide at most three tags that well represent the document. Each tag should not have more than three words.

Provide the tag in the number form.

Be factual and do not hallucinate. Remember to act as a cell in a spreadsheet and provide concise, relevant information without explanations unless specifically requested.

4. Basic Implementation

4.1 Simple Document Processor

def process_single_news(document_path):
    # Upload document file
    file_response = client.file.upload_file(document_path)

    # Process in action table
    response = client.table.add_table_rows(
        table_type=t.TableType.ACTION,
        request=t.MultiRowAddRequest(
            table_id="news_summarization",
            data=[{"document": file_response.uri}],
            stream=False,
        ),
    )

    # Extract results
    return {
        "summary": response.rows[0].columns["summary"].text,
        "tag": response.rows[0].columns["tag"].text
    }

4.2 Complete Implementation with Error Handling

class DocumentProcessor:
    def __init__(self, project_id: str, pat: str):
        self.client = JamAI(
            project_id=project_id,
            token=pat
        )

    def validate_document(self, document_path: str) -> bool:
        """Validate if file exists and has correct extension"""
        if not os.path.exists(document_path):
            raise FileNotFoundError(f"Document not found: {document_path}")

        valid_extensions = [
            '.csv', '.tsv', '.txt', '.md', '.doc', '.docx', '.pdf', 
            '.ppt', '.pptx', '.xls', '.xlsx', '.xml', '.html', 
            '.json', '.jsonl'
        ]
        
        file_ext = os.path.splitext(document_path)[1].lower()
        if file_ext not in valid_extensions:
            raise ValueError(f"Unsupported file format. Use: {valid_extensions}")

        return True

    def process_document(self, document_path: str) -> Optional[Dict[str, str]]:
        """Process a single document file"""
        try:
            # Validate document
            self.validate_document(document_path)

            # Upload file
            print("Uploading document...")
            file_response = self.client.file.upload_file(document_path)
            print(f"Upload successful: {file_response.uri}")

            # Process in action table
            print("Processing document...")
            response = self.client.table.add_table_rows(
                table_type=t.TableType.ACTION,
                request=t.MultiRowAddRequest(
                    table_id="news_summarization",
                    data=[{"document": file_response.uri}],
                    stream=False,
                ),
            )

            # Extract and return results
            results = {
                "summary": response.rows[0].columns["summary"].text,
                "tag": response.rows[0].columns["tag"].text
            }
            print("Processing complete!")
            return results

        except Exception as e:
            print(f"Error processing document: {str(e)}")
            return None

5. Usage Examples

5.1 Basic Usage

# Initialize processor
processor = DocumentProcessor(PROJECT_ID, PAT)

# Process single receipt
result = processor.process_document("path/to/news.txt")

if result:
    print(f"Summary: {result['summary']}")
    print(f"Tag: {result['tag']}")

5.2 Batch Processing

def process_document_batch(document_folder: str):
    processor = DocumentProcessor(PROJECT_ID, PAT)
    results = []

    for filename in os.listdir(document_folder):
        # Check if file has a supported document extension
        valid_extensions = [
            '.csv', '.tsv', '.txt', '.md', '.doc', '.docx', '.pdf', 
            '.ppt', '.pptx', '.xls', '.xlsx', '.xml', '.html', 
            '.json', '.jsonl'
        ]
        
        if any(filename.lower().endswith(ext) for ext in valid_extensions):
            document_path = os.path.join(document_folder, filename)
            result = processor.process_document(document_path)
            if result:
                results.append({
                    "filename": filename,
                    **result
                })

    return results

# Usage
results = process_document_batch("path/to/documents/folder")
for result in results:
    print(f"File: {result['filename']}")
    print(f"Summary: {result['summary']}")
    print(f"Tag: {result['tag']}")
    print("---")

6. Best Practices

Error Handling
- Always validate input files
- Handle network errors gracefully
Performance
- Reuse the client instance
- Consider batch processing for multiple files
- Implement rate limiting for large batches
Security
- Use environment variables for credentials
