Abstract
This seminar presents an proposal for institutional knowledge management, addressing the challenge of transforming fragmented repositories into a unified system designed to deliver verifiable and explainable answers. Traditional retrieval systems are limited to document matching, offering no traceability for relevance or connection to the user's query. This research-in-progress breaks that limitation by introducing a reasoning-centered approach: the model not only aims to find information but critically reveals why an answer is correct by establishing meaningful links among entities, processes, and regulations.
The conceptual operational model is structured around five key pillars: (1) integrated access to heterogeneous sources while strictly respecting permissions and data sensitivity; (2) generation of answers only when supported by documented evidence; (3) the ability to handle complex, multi-step queries; (4) on-premise deployment to ensure strict data privacy; and (5) continuous evaluation using metrics specifically designed to measure relevance, traceability, and transparency. Within this proposed framework, user questions evolve from simple searches into exercises in discovering connections, providing not just data, but the complete reasoning structure that supports the knowledge.
