margfeldis

Margfeldis is a theoretical construct used in discussions of discourse structure and information networks to describe the degree to which a proposition, term, or piece of evidence is located at the periphery of a discourse, despite often bearing substantial semantic importance. It is used to examine how placement, framing, and rhetorical devices influence perceived centrality within texts and debates.

Etymology: The term combines marg- from marginal or edge and feldis as a suffix suggesting a field or domain; the compound is intended to evoke the contrast between central claims and peripheral data within a text or argument.

The margfeldis score is a composite index derived from three components: marginality index (the graph-based distance from the main claim), evidential salience (frequency and strength of supporting cues), and audience perception (measured by surveys or proxy signals in text data). Together, these elements aim to quantify how far a piece of information sits from the discourse’s core, even when its content is semantically significant.

In practice, margfeldis helps analyze why some high-importance information appears peripheral. It is used in discourse analysis, summarization, and explainable AI to flag peripheral but influential elements that may affect comprehension, memory, or decision-making.

Examples include political speeches where critical policies are introduced in asides, or scientific papers where a novel method is cited briefly in footnotes. In both cases, marginal data can disproportionately affect reader judgments and the perceived robustness of a central claim.

The term originated in speculative literature and has been discussed mainly in thought experiments and analytical discussions. It is not yet established as a standard measure in empirical linguistics, and its definitions vary by context.
