Abstract

This study presents a novel fuzzy logic framework to quantitatively evaluate dialogue coherence, integrating mathematical modeling with an experimental case study approach. Recognizing that dialogue coherence is a continuous and multidimensional construct, we employ fuzzy set theory to design membership functions for critical linguistic variables, including topical continuity, syntactic alignment, and semantic relevance. Unlike traditional binary metrics, our approach computes a continuous coherence score using a weighted aggregation model, where each score is deriving expert-calibrated fuzzy inference rules. The empirical case study uses a heterogeneous dialogue corpus, consisting of interview transcripts and natural conversation recordings. The corpus was split into segments, with the segments annotated by linguistic experts. The Pearson correlation statistical analysis shows a strong correlation between the fuzzy coherence scores and the expert ratings, highlighting the robustness and reliability of the method. The research elaborates on implications for communication studies, such as applications to therapy, education, and human-computer interaction, as well as its limitations like subjectivity in defining the rules or challenges for scaling it. We conclude by proposing several lines of future research, such as incorporating additional variables spanning linguistic and non-verbal aspects and creating methods for automated calibration that would allow the model to personalize itself over time. In summary, our study confirms the usage of fuzzy logic systems with respect to the subtle gradience of dialogue coherence, enriching not just the theoretical notions of a dialogue but also being used as an exhaust model for classification.
