This paper presents a hybrid model that combines linguistic data summarization techniques, algorithms for constructing probabilistic trees, and various Generative Artificial Intelligence models for learning and generating linguistic summaries to aid decision-making. The proposal is validated using methodological triangulation techniques that demonstrate high consistency in the knowledge discovered. The proposal also compares different Generative Artificial Intelligence models; among the evaluated models, Gemini achieved the best performance. However, it is evident that in certain contexts and tasks, small language models can be effective, yielding results comparable to Large Language Models (LLMs) at a lower computational cost. This study applies the algorithms in a case study analyzing oceanographic data from northern Chile. In the validation scenario, the combination of linguistic data summarization methods with unsupervised learning techniques effectively models human tolerance for imprecision when processing complex data and generated linguistic summaries easily interpretable by human decision-makers with high levels of confidence. Studies of energy capacities in the studied region and their behavior in both winter and summer are presented.
