Bridging privacy-preserving approaches: a formal comparison of k-automorphism, k-isomorphism, and k-symmetry

EURASIP Journal on Information Security
Anonymization of graph data is fundamental to preserving users’ privacy while publishing social network datasets. The strongest privacy guarantees against any structural attacks provide three well-known methods: k-automorphism, k-isomorphism and k ...

A Framework for Impression Management in Extra‐Financial Reporting

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper examines how organisations employ impression management tactics in extra‐financial reporting, particularly in the context of environmental, social and governance (ESG) concerns. As stakeholder scrutiny and regulatory expectations intensify, organisations increasingly shape non‐financial disclosures to influence perceptions of ...

Graph isomorphism, general remarks [PDF]

, 1979
An open question is the computational complexity of recognizing when two graphs are isomorphic. In an attempt to answer this question we shall analyze the relative computational complexity of generalizations and restrictions of the graph isomorphism ...

DeepTGIN: a novel hybrid multimodal approach using transformers and graph isomorphism networks for protein-ligand binding affinity prediction

Journal of Cheminformatics
Predicting protein-ligand binding affinity is essential for understanding protein-ligand interactions and advancing drug discovery. Recent research has demonstrated the advantages of sequence-based models and graph-based models. In this study, we present

An Empirical Study on the Evaluation of Graph‐Based Strategies for Intelligent Modeling Assistants

Software: Practice and Experience, EarlyView.
ABSTRACT Context In the context of model‐driven engineering, the proliferation of intelligent modeling assistants (IMAs) has pushed the boundaries of automation, providing modelers with relevant recommendations based on incomplete modeling artifacts as primary input.

Toward an Intermediate Structural Representation of Organization in Complex Systems

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Organization is widely recognized as a fundamental concept in complex systems science, yet it rarely appears as an explicit object of scientific representation. Existing approaches successfully represent components, interactions, mechanisms, dynamical states, networks, or functions, but organizational properties are generally inferred from ...

Generating Compressed Counterfactual Hard Negative Samples for Graph Contrastive Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Graph contrastive learning (GCL) relies on acquiring high‐quality positive and negative samples to learn the structural semantics of the input graph. Previous approaches typically sampled negative samples from the same training batch or an irrelevant external graph.

GINMCL: graph isomorphism network-driven modality enhancement and cross-modal consistency learning for multi-modal fake news detection [PDF]

PeerJ Computer Science
Multi-modal fake news detection is a technique designed to identify and classify fake news by integrating information from multiple modalities. However, existing multi-modal fake news detection models have significant limitations in capturing structural ...

Urban inequalities and marginalization of the Social and Solidarity Economy: A comparative analysis in the Sants‐Montjuïc district in Barcelona

Annals of Public and Cooperative Economics, EarlyView.
Abstract This article examines how urban inequalities influence the Social and Solidarity Economy (SSE) through a study of two Barcelona neighbourhoods. It evaluates the limitations of SSE promotion policies implemented between 2016 and 2024, focusing on their impact on diversifying socio‐enterprise initiatives and fostering cooperative ecosystems with
