GPT-based Universal Web Scraper - Requirements Document

1. Project Objective

  • Develop a GPT-based universal web scraper that intelligently interacts with users, adapts to different website structures, and accurately extracts the desired information.

2. Key Features

a. URL Preprocessing

  • Normalize and validate user-provided URLs.
  • Handle URL redirections and fetch website content.
  • Process and parse the HTML content into a structured DOM tree.

b. GPT-based User Interaction

  • Generate natural language prompts to ask users about their scraping needs.
  • Process user responses to identify their preferences and guide the extraction process.

c. Website Structure Analysis

  • Analyze the website's structure, layout, and metadata to identify target elements and patterns.
  • Leverage GPT to process descriptive text within the website for additional context.

d. Scraper Generation

  • Create a tailored scraper to extract the identified elements and patterns.
  • Apply heuristics or machine learning models to optimize scraper performance.

e. Data Extraction

  • Execute the generated scraper to extract the desired information.
  • Perform data normalization and cleaning as necessary.
  • Allow users to provide feedback to refine the process.

f. Scalability and Robustness

  • Handle different website types, structures, and formats.
  • Implement rate limiting, caching, and other optimizations to improve efficiency.

g. Continuous Learning and Improvement

  • Collect user feedback and performance metrics for iterative improvements.
  • Employ transfer learning and other techniques to generalize knowledge across websites.

3. Target Audience

  • Data analysts, data scientists, researchers, developers, and other professionals who need to extract information from websites for various purposes.

4. User Requirements

  • Easy-to-use interface that guides users through the scraping process.
  • Clear instructions and examples to help users understand how to provide input and interpret results.
  • Ability to handle various website structures and formats without requiring extensive user input or customization.
  • Reliable and accurate extraction of the desired information.
  • Robust performance, even when faced with anti-bot measures or other challenges.
  • Continuous improvements and updates based on user feedback and industry trends.
