Abstract
A system for improving retrieval augmentation for information extraction systems deployed over multiple contexts or fields. Representative documents for the context are obtained and used to modify the vector embedding. The documents may be used to generate a frequency term related to the frequency of word term within the context and an inverse prevalence term related to how unique it is for a document to include the word term. The frequency term and the inverse prevalence term are combined into a weight for the respective word term. Weights are used generate a vector text embedding for portions of the document by calculating a weighted average of the word terms in the portion of the document. Retrieval of relevant documents is based on the semantic comparison of the vector text embeddings and an embedding for the information to be extracted and is tailored to the context using the weights.
