These techniques may include paragraph-based segmentation, topic-based segmentation, such as using natural language processing techniques, semantic similarity-based clustering, named entity recognition for entity-centric segmentation, and/or temporal or chronological segmentation for time-based content). With respect to claim 4, Zhang et al teaches extracting the one or more keywords from the question using an NLP and one or more third vectors generated for the one or more keywords by the embedding LLM, wherein the converting the question to the first vector is based, at least in part, on the one or more third vectors generated for the one or more keywords ([0054] performing one or more other segmentation techniques to divide raw information item 204 into, or otherwise extract, smaller units of information. paragraph-based segmentation, topic-based segmentation, such as using natural language processing techniques, semantic similarity-based clustering, named entity recognition for entity-centric segmentation, and/or temporal or chronological segmentation for time-based content). With respect to claim 5, Zhang et al teaches prompting the summarization LLM with an instruction to generate the answer using the one or more matches each in the corresponding one of the plurality of data formats, and wherein the answer summarizes the one or more matches in a text format corresponding to the question ([0029] Depending on the model, data formats may be more effective than others for fine-tuning to better results compared to other formats (e.g., such as a raw text corpus, also referred to herein as a “raw information item”). Thus, strategies for formatting knowledge prior to LLM fine-tuning) With respect to claim 6, Zhang et al teaches receiving feedback associated with the answer; and updating at least one data retrieval module associated with the performing the search based on the feedback ([0069] Fine-tuning 216 results in obtaining a fine-tuned second language model 220 (e.g., a fine-tuned version of second language model 217).
