Abstract: Systems and methods for improving the accuracy of information obtained using a large language model. In one embodiment, this involves augmenting the capabilities of a graph generated from unstructured data with information from an external source using Retrieval Augmented Generation (RAG). In one embodiment, expert knowledge is used to review clustering and cluster summarizations derived from the results of a search over the graph data and information prior to application of RAG to generate additional information to augment the search results.
