## Summary

The paper presents a methodology for identifying knowledge gaps on the internet using the Retrieval Augmented Generation (RAG) model. By simulating user search behavior, the RAG system effectively pinpoints and addresses gaps in information retrieval systems. The study showcases the impressive accuracy rate of 93% achieved by the RAG system in generating relevant suggestions. This methodology has broad applications across various fields such as scientific discovery, education enhancement, research development, market analysis, search engine optimization, and content development. To determine query complexity, queries are categorized as easy or difficult based on factors such as length, specificity, use of jargon or technical terms, ambiguity or clarity of query, search intent, required knowledge level and format. Metrics including accuracy rate and topic depth measured by iterations until the system stops answering questions were analyzed for each search simulation conducted using these criteria. The study involved 60 keywords generating 323 answers from 655 sources. Results indicated that using more than 60 keywords did not significantly impact outcomes. The RAG system consistently achieved an accuracy rate of 93% for both simple and complex queries. It was also observed that finding sources became slightly more challenging for specific topics; however, no significant differences were noted in accuracy or source quantity across categories due to balanced category selection. The ability of the RAG system to simulate user search behavior effectively makes it a reliable tool for information retrieval. It aids in improving search engine optimization by identifying missing content that users may be looking for online. Additionally, it assists in content development by recognizing content gaps within libraries and guiding creators to fill those voids. In conclusion,the study successfully demonstrates a methodology for identifying knowledge gaps in content libraries with potential for future expansion through alternative search simulation methods like utilizing agents with enhanced capabilities beyond human users.Further evaluation with additional answer engines could provide a more comprehensive estimation of the outlined methodology's effectiveness.
