Ontology Maintenance using Textual Analysis [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2003
Ontologies are continuously confronted to evolution problem. Due to the complexity of the changes to be made, a maintenance process, at least a semi-automatic one, is more and more necessary to facilitate this task and to ensure its reliability.

Emotions and virality: Social transmission of political messages on Twitter

open access: yesFrontiers in Psychology, 2022
Drawing on previous literature that valence and arousal constitute the fundamental properties of emotions and that emotional content is a determinant of social transmission, this study examines the role of valence and arousal in the social transmission ...

Virality and Susceptibility in Information Diffusions

open access: yesProceedings of the International AAAI Conference on Web and Social Media, 2021
Viral diffusion allows a piece of information to widely and quickly spread within the network of users through word-ofmouth. In this paper, we study the problem of modeling both item and user factors that contribute to viral diffusion in Twitter network.

Innovation diffusion in time and space: effects of social information and of income inequality [PDF]

open access: yes, 2009
In this paper we consider the spread of modern technological innovations. We contrast social learning and threshold heterogeneity models of innovation diffusion, and show how the typical temporal evolution of the distribution of adopters may be ...

Diffusion in Cauchy Elastic Solid [PDF]

open access: yes, 2022
It is commonly accepted that a starting point of the science of diffusion is the phenomenological diffusion equation postulated by German physiologist Adolf Fick inspired by experiments on diffusion by Thomas Graham and Robert Brown.

Risk Assessment of World Corn Salinization Hazard Factors Based on EPIC Model and Information Diffusion

open access: yesLand, 2023
Salinization is a serious land degradation phenomenon. This study identified the salinity stress threshold as a causal factor for salinization, focusing on global maize fields as the study area.

Diffusion in Metals and Intermetallics: An Overview [PDF]

open access: yes, 2022
After a few remarks about the history of diffusion in solids we remind the reader to some basics of diffusion such as tracer diffusion, interdiffusion, high-diffusivity paths, and basic diffusion mechanism in solids.

SpreadRank: A Novel Approach for Identifying Influential Spreaders in Complex Networks

open access: yesEntropy, 2023
Identifying influential spreaders in complex networks is critical for information spread and malware diffusion suppression. In this paper, we propose a novel influential spreader identification method, called SpreadRank, which considers the path ...

Information Diffusion and Economic Development [PDF]

open access: yesProceedings of the 2017 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining 2017, 2017
In many developing countries there remains a limited view on the socioeconomic status of the population, owing to the high cost associated with detailed and comprehensive surveying. This situation has encouraged a number of researchers to attempt to exploit alternative sources of data in order to derive estimates, including mobile phone data, which ...

Investigating effects from restricted diffusion in multi-component diffusion data [PDF]

open access: yes, 2014
We have investigated model systems in which effects from non-Gaussian restricted diffusion could be separated from effects caused by multiple diffusion coefficients. We applied various models to analyze the experimental data.
