Collective Hysteresis and Multistability in Threshold Networks
Moses Boudourides
In a mechanistic model of the dawn chorus, Kaye showed that heterogeneous activation thresholds and a shared feedback signal determined by the population's active fraction can prod…
LLMs for Qualitative and Mixed-Methods Social Network Analysis
Moses Boudourides
This manuscript explores the integration of Large Language Models (LLMs) into the field of qualitative and mixed-methods social network analysis (SNA). We argue that the primary fo…
Missing Links in Public Email and Covert Networks: A Comparative Evaluation of Link Prediction, Hyperlink Prediction, and ERGM Estimation
Moses Boudourides
We study missing-link inference in partially observed networks by systematically comparing dyadic link prediction (LP) with hyperlink prediction (HP) and an estimation-based ERGM c…
A Multi-Source Framework for Relational Validation of Large Language Models Using Expert-Curated Encyclopedic Sources
Moses Boudourides
This paper introduces a novel, multi-source framework for the relational validation of Large Language Models (LLMs). While existing benchmarks have demonstrated LLMs' proficiency a…
Borda Aggregation Dynamics of Preference Orderings on Networks
Moses Boudourides
We introduce and analyze a discrete-time network process in which each node holds a (weak) preference ordering over a finite set of alternatives and updates by local Borda aggregat…
The Algorithmic Blind Spot: Bias, Moral Status, and the Future of Robot Rights
Rahulrajan Karthikeyan, Moses Boudourides
Contemporary debates in AI ethics increasingly foreground the prospective moral status of artificial intelligence and the possibility of extending moral or legal rights to artifici…
From Line Knowledge Digraphs to Sheaf Semantics: A Categorical Framework for Knowledge Graphs
Moses Boudourides
This paper proposes a categorical framework for knowledge graphs linking combinatorial graph structure with topos-theoretic semantics. Knowledge graphs are represented as labelled…
Two-Path Operators, Triadic Decompositions, and Majorized Quotients for Ego-Centered Network Compression
Moses Boudourides
Two-paths (wedges) are the elementary combinatorial objects behind clustering, triadic closure, redundancy, and brokerage. Motivated by a two-path formalism that links Burt's struc…
Structural Hallucination in Large Language Models: A Network-Based Evaluation of Knowledge Organization and Citation Integrity
Moses Boudourides
Large Language Models (LLMs) increasingly mediate access to scholarly information, yet their outputs are typically evaluated at the level of individual statements rather than knowl…
Boundary-Value Friedkin-Johnsen Dynamics and Influence-Based Centralities on Networks
Moses Boudourides
Understanding which nodes are most able to transmit or receive influence is a central problem in networked opinion dynamics, yet topology-only centrality measures do not account fo…
Interior--Boundary Assortativity Profiles on Networks and Applications to SIS Epidemic Dynamics
Moses Boudourides
We introduce \emph{interior--boundary assortativity profiles} as a structural refinement of Newman's assortativity coefficient and show that they arise naturally from \emph{epidemi…
