Extracting Insights from Complex Documents with Llama Index

Discover how Llama Index, a powerful framework, enables developers to extract valuable insights from complex documents. By utilizing this framework, accurate and sophisticated results can be obtained when comparing and analyzing PDF documents with structured data and financial tables.

The Challenge of Document Comparison

A naive approach of simply chopping up documents and using similarity search in a vector database can result in inaccurate results and hallucinations. To overcome this challenge and handle more complex queries, a more advanced approach is required.

The Power of Llama Index

Llama Index serves as a framework for building Language Model Maps (LM Maps) over data. It allows for the extraction of insights from complex documents and facilitates handling advanced questions.

Example: Comparing Revenue Growth

The text provides an example of comparing the revenue growth of Uber and Lyft from 2020 to 2021. Llama Index accurately extracts the relevant information from both documents, ensuring correct results.

Understanding Llama Index
