AI-powered Data Extraction

Best LLM Models for Data Extraction

These are the models we have tried to extract data from a webpage in HTML. Below, we explore the performance of several models we’ve tested for extracting specific data into structured formats like markdown tables from HTML pages.

This is the prompt we used to evaluate different models, and we fetched unstructured data from HTML and showed it as Markdown table.

Llama 3.2 Model

This model, while innovative in its architecture, showed limitations when it came to adhering strictly to the prompts provided for data extraction. In our task, the model extracted all data, and not the specified data in the prompt.

Anthropic AI Models

The Haiku model from Anthropic AI stood out in our evaluation. It demonstrated a robust capability to not only understand the prompt but also to execute the extraction task with high fidelity. It excelled in parsing HTML content and formatting the extracted data into well-structured markdown tables. The model’s ability to maintain context and follow detailed instructions made it particularly effective for this use case.

Although Haiku Model is the smallest model of Anthropic, it did a better job than any other model in the Eval.

OpenAI Models

While OpenAI models are renowned for their versatility and language understanding, they didn’t shine as brightly in our specific task of converting HTML to markdown tables. The primary issue encountered was with the formatting of the markdown table. The model occasionally produced tables with misaligned columns or inconsistent markdown syntax, which required manual tweaking post-extraction. There were a lot of placeholders in the generated OpenAI output.

Methods of Data Extraction

Data extraction methods are crucial for businesses that want to make the most of their data. These methods come in different levels of complexity and are suited for various types of data and business needs.

Web Scraping

Web scraping is a popular way to gather data directly from websites. It involves using automated tools or scripts to collect large amounts of data from web pages. This method is especially helpful for collecting publicly available information like prices, product details, or customer reviews. Tools such as BeautifulSoup and Cheerio are well-known for scraping content from static web pages. Moreover, AI-powered scrapers can automate and improve the process, saving time and effort.

Text Extraction

Text extraction is all about getting specific information from sources that are mostly text. This method is important for working with documents, emails, and other text-heavy formats. Advanced text extraction techniques can find and pull out patterns or entities, such as names, dates, and financial figures from unstructured text. Often, this process is aided by machine learning models that become more accurate and efficient over time.

API Tools

API tools make data extraction easier by offering a structured way to access data from external sources. Through APIs, businesses can get data from various services like social media platforms, databases, and cloud applications securely and efficiently. This approach is perfect for integrating real-time data into business applications, ensuring a smooth data flow and up-to-date information.

Data Mining

Data mining is about analyzing large sets of data to uncover patterns, correlations, and insights that aren’t immediately obvious. This method is invaluable for businesses that want to optimize processes, predict trends, or understand customer behavior better. Data mining techniques can be used on both structured and unstructured data, making them versatile tools for strategic decision-making.

OCR (Optical Character Recognition)

OCR technology converts written text, like handwritten notes or printed documents, into digital data that can be edited and searched. This method is particularly useful for turning paper-based information into digital format, helping businesses to streamline document management and improve access to data. OCR engines have become more advanced, offering high accuracy and speed when converting physical documents into digital formats.

Adding these data extraction methods into a business plan can significantly boost data processing abilities, leading to better decision-making and improved operational efficiency. By choosing the right method or combination of methods, businesses can ensure they are making the most of their data.
