Beyond the intentional spread of false information, it often appears as narrative divergence among sources interpreting shared events, generating fragmentation and measurable losses in structural coherence. This study examines disinformation within an entropic structural framework, defining it as narrative disorder and epistemic incoherence in information systems. The approach moves beyond fact-checking by treating narrative structure and informational order as quantifiable attributes of public communication. We present the QVP-RI (Relational Information Valuation) operator, a computational model that quantifies narrative divergence through informational entropy and normalized structural divergence, without issuing truth assessments. Implemented through state-of-the-art NLP pipelines and entropic analysis, the operator maps narrative structure and epistemic order across plural media environments. Unlike accuracy-driven approaches, it evaluates narrative coherence and informational utility (IU) as complementary indicators of epistemic value. Experimental validation with 500 participants confirms the robustness of the structural\u2013entropic model and identifies high divergence regions, revealing communication vulnerabilities and showing how narrative disorder enables disinformation dynamics. The QVP-RI operator thus offers a computationally grounded tool for analyzing disinformation as narrative divergence and for strengthening epistemic order in open information systems.<\/jats:p>","DOI":"10.3390\/e28020183","type":"journal-article","created":{"date-parts":[[2026,2,6]],"date-time":"2026-02-06T10:05:47Z","timestamp":1770372347000},"page":"183","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Narrative Divergence and Disinformation: An Entropic Model for Assessing the Informative Utility of Public Information Sources"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2606-3849","authenticated-orcid":false,"given":"Jos\u00e9 Ignacio","family":"Pel\u00e1ez","sequence":"first","affiliation":[{"name":"Center for Applied Social Research (CISA), University of M\u00e1laga, 29010 M\u00e1laga, Spain"},{"name":"Department of Languages and Computer Science, University of M\u00e1laga, 29071 M\u00e1laga, Spain"},{"name":"Biomedical Research Institute of M\u00e1laga (IBIMA), University of M\u00e1laga, 29071 M\u00e1laga, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2097-2291","authenticated-orcid":false,"given":"Gustavo Fabian","family":"Vaccaro","sequence":"additional","affiliation":[{"name":"Center for Applied Social Research (CISA), University of M\u00e1laga, 29010 M\u00e1laga, Spain"},{"name":"Biomedical Research Institute of M\u00e1laga (IBIMA), University of M\u00e1laga, 29071 M\u00e1laga, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felix Infante","family":"Le\u00f3n","sequence":"additional","affiliation":[{"name":"Center for Applied Social Research (CISA), University of M\u00e1laga, 29010 M\u00e1laga, Spain"},{"name":"Biomedical Research Institute of M\u00e1laga (IBIMA), University of M\u00e1laga, 29071 M\u00e1laga, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,6]]},"reference":[{"key":"ref_1","unstructured":"European Commission (2018).
