ScrapeGraphAI x LlamaIndex：并购数据提取的革新者

In the ever-evolving landscape of data extraction, the integration of ScrapeGraphAI with LlamaIndex has unlocked powerful capabilities for structured content extraction. Whether you're monitoring mergers and acquisitions (M&A) or extracting detailed company information, this integration simplifies the workflow and ensures accuracy.

In this blog, we'll walk you through:

1. How to integrate ScrapeGraphAI with LlamaIndex.
2. An example use case: Extracting M&A data using the combined power of ScrapeGraphAI and LlamaIndex.
3. A practical Python implementation.

Why LlamaIndex + ScrapeGraphAI?

The partnership between ScrapeGraphAI and LlamaIndex combines advanced AI-driven web scraping with LlamaIndex's indexing and querying capabilities. This integration enables:

• Seamless structured data extraction.
• Defined output schemas for consistency.
• Enhanced scalability for dynamic content needs.

Getting Started

Step 1: Install Dependencies

To use the tools, install the required Python packages:

bash
pip install llama-index
pip install llama-index-tools-scrapegraphai

Step 2: Import Your ScrapeGraph API Key

You'll need to set up your API key securely:

python
import os
from getpass import getpass

# Check if the API key is already set in the environment
sgai_api_key = os.getenv("SGAI_API_KEY")

if sgai_api_key:
    print("SGAI_API_KEY found in environment.")
else:
    print("SGAI_API_KEY not found in environment.")
    # Prompt the user to input the API key securely (hidden input)
    sgai_api_key = getpass("Please enter your SGAI_API_KEY: ").strip()
    if sgai_api_key:
        # Set the API key in the environment
        os.environ["SGAI_API_KEY"] = sgai_api_key
        print("SGAI_API_KEY has been set in the environment.")
    else:
        print("No API key entered. Please set the API key to continue.")

Defining Output Schemas

Output schemas provide a blueprint for the data you want to extract. Using Pydantic, you can define schemas for both simple and complex data structures.

Simple Schema Example

For straightforward information extraction:

python
from pydantic import BaseModel, Field

class PageInfoSchema(BaseModel):
    title: str = Field(description="The title of the webpage")
    description: str = Field(description="The description of the webpage")

Complex Schema Example

For structured data with multiple related items:

python
from pydantic import BaseModel, Field
from typing import List, Dict, Optional

# Schema for founder information
class FounderSchema(BaseModel):
    name: str = Field(description="Name of the founder")
    role: str = Field(description="Role of the founder in the company")
    linkedin: str = Field(description="LinkedIn profile of the founder")

# Schema for pricing plans
class PricingPlanSchema(BaseModel):
    tier: str = Field(description="Name of the pricing tier")
    price: str = Field(description="Price of the plan")
    credits: int = Field(description="Number of credits included in the plan")

# Schema for social links
class SocialLinksSchema(BaseModel):
    linkedin: str = Field(description="LinkedIn page of the company")
    twitter: str = Field(description="Twitter page of the company")
    github: str = Field(description="GitHub page of the company")

# Schema for company information
class CompanyInfoSchema(BaseModel):
    company_name: str = Field(description="Name of the company")
    description: str = Field(description="Brief description of the company")
    founders: List[FounderSchema] = Field(description="List of company founders")
    logo: str = Field(description="Logo URL of the company")
    partners: List[str] = Field(description="List of company partners")
    pricing_plans: List[PricingPlanSchema] = Field(description="Details of pricing plans")
    contact_emails: List[str] = Field(description="Contact emails of the company")
    social_links: SocialLinksSchema = Field(description="Social links of the company")
    privacy_policy: str = Field(description="URL to the privacy policy")
    terms_of_service: str = Field(description="URL to the terms of service")
    api_status: str = Field(description="API status page URL")

Extracting Data with ScrapeGraphAI and LlamaIndex

Here's how to extract structured data using our schema:

python
from llama_index.tools.scrapegraph.base import ScrapegraphToolSpec

scrapegraph_tool = ScrapegraphToolSpec()

def extract_company_info(url: str, api_key: str):
    response = scrapegraph_tool.scrapegraph_smartscraper(
        prompt="Extract detailed company information including name, description, industry, founding year, employee count, location details, and contact information",
        url=url,
        api_key=api_key,
        schema=CompanyInfoSchema,
    )
    return response["result"]

url = "https://scrapegraphai.com/"
company_info = extract_company_info(url, sgai_api_key)

Output:

To process and save the extracted data:

python
import pandas as pd

# Flatten and organize the data
company_info_flat = {
    "company_name": company_info["company_name"],
    "description": company_info["description"],
    "founders": company_info["founders"],
    "logo": company_info["logo"],
    "partners": company_info["partners"],
    "pricing_plans": company_info["pricing_plans"],

    "linkedin": company_info["social_links"]["linkedin"],
    "twitter": company_info["social_links"]["twitter"],
    "github": company_info["social_links"].get("github", None)
}

# Create separate DataFrames for different aspects
df_company = pd.DataFrame([company_info_flat])
df_founders = pd.DataFrame(company_info["founders"])
df_pricing = pd.DataFrame(company_info["pricing_plans"])
df_partners = pd.DataFrame({"partner": company_info["partners"]})
