Automatic Generation of Study Texts from Lecture Slides
Resumo
Generative artificial intelligence has expanded the potential for automated educational content generation to support teaching and independent learning. Among these resources, lecture slides play a central role, yet their concise visual format limits its use for asynchronous study by students. This work proposes a method to automatically transform slide decks into self-contained study documents. The solution integrates visual parsing, iterative discourse reconstruction, and knowledge retrieval to ground implicit lecture concepts. Experiments across four multimodal LLMs show the generation of coherent materials while highlighting operational trade-offs.Referências
