Converting Italian Election Poll Text to Structured Data Using Large Language Models

The llm_italian_poll_scraper project uses large language models (LLMs) to convert unstructured Italian election poll text into machine-readable structured data. It addresses the pain points of traditional data processing—low efficiency, high error rates, and loss of context—opening up new paths for political data analysis, and has both practical application value and cross-domain expansion potential.

Italian election poll data has issues of inconsistent formats and scattered information. Traditional methods rely on rule engines or regular expressions, which struggle with variable documents; manually organizing hundreds of reports is inefficient and error-prone, and contextual information is often lost. The semantic understanding capability of LLMs provides a new idea to solve this dilemma.

The project uses a complete pipeline: crawl documents such as PDFs, web pages, and scanned copies → convert to raw text via OCR or text extraction → use prompts to guide LLMs to extract key fields like survey institutions, sample size, and party support rates → ensure quality through format verification, abnormal mark review, and historical data consistency checks.

Political analysts can reduce weeks of organizing work to a few hours; structured data supports advanced analysis such as trend prediction and modeling. Open-format data makes it easier for journalists and citizens to monitor elections, verify official statements, promote public discussion, and contribute to democratic transparency.

The project's methodology (LLM semantic understanding + traditional verification) can be replicated in fields such as finance, law, and medicine. With the development of multimodal models, future versions can process inputs like charts, video subtitles, and audio, further lowering the threshold for data acquisition.

This project is a solid engineering practice focusing on specific scenarios, using AI to effectively solve data problems, and providing a valuable reference example for the application of LLMs in professional fields.
