Title

"From RAGs to riches? An efficient pipeline for exploratory text analysis"

Abstract

I introduce a scalable computational approach for comparing large bodies of text across many research questions using retrieval-augmented generation (RAG). By combining language models with domain-specific retrieval, the method enables fast, flexible, and customizable text analysis - offering a powerful alternative to traditional document-by-document approaches.
