Measuring Diversity in Heterogeneous Information Networks [article]

Pedro Ramaciotti Morales, Robin Lamarche-Perrin, Raphael Fournier-S'niehotta, Remy Poulain, Lionel Tabourier, Fabien Tarissan
2020 arXiv   pre-print
In this article, we develop a formal framework for the application of a large family of diversity measures to heterogeneous information networks (HINs), a flexible, widely-used network data formalism.  ...  In doing so, we not only provide an effective organization of multiple practices from different domains, but also unearth new observables in systems modeled by heterogeneous information networks.  ...  In this section, we apply true diversity measures to these distributions, completing the framework for the measurement of diversity in heterogeneous information networks.  ...

Network Learning: The Effects of Partners' Heterogeneity of Experience on Corporate Acquisitions

Christine M. Beckman, Pamela R. Haunschild
2002 Administrative Science Quarterly  
Model 4 of table 2 includes the measure of network diversity. In support of H1c, firms whose networks are diverse pay higher premiums than firms in networks with less unique information.  ...  If diverse information aids in organizational learning, firms in diverse networks should pay lower premiums than firms in less networks.  ...

Measure for degree heterogeneity in complex networks and its application to recurrence network analysis

Rinku Jacob, K. P. Harikrishnan, R. Misra, G. Ambika
2017 Royal Society Open Science  
We show that the proposed measure can be applied to all types of network topology with ease and increases with the diversity of node degrees in the network.  ...  The measure is applied to compute the heterogeneity of synthetic (both random and scale free) and real world networks with its value normalized in the interval [0, 1].  ...  networks.  ...

Political Diversity and Participation: A Systematic Review of the Measurement and Relationship

Najin Jun
2014 Asian Journal for Public Opinion Research  
As the measure of political diversity, political network heterogeneity and network attributes are discussed in detail in specific relation to political participation.  ...  This study reviews existing research on the measurement of and the relationship between political diversity and political participation.  ...  For example, political diversity is often measured by the level of exposure to non-likeminded political information in one's social network.  ...

Heterogeneous networking

Yongguang Zhang, Harrick Vin, Lorenzo Alvisi, Wenke Lee, Son K. Dao
2001 Proceedings of the 2001 workshop on New security paradigms - NSPW '01  
In contrast, in a network in which each critical functionality is provided by a diverse set of protocols and implementations, attacks that focus on a weakness of one such protocol or implementation will  ...  We believe that a network, to be survivable, must be heterogeneous.  ...  One measure is the cumulative diversity distance between all pairs of elements in the set. Another measure can be the number of distinct attacks that the set can tolerate.  ...

AIRank: Author Impact Ranking through Positions in Collaboration Networks

Jun Zhang, Yan Hu, Zhaolong Ning, Amr Tolba, Elsayed Elashkar, Feng Xia
2018 Complexity  
Our method not only considers the impact of scholars through the mutual reinforcement process in heterogeneous academic networks, but also integrates the structural holes theory and information entropy  ...  Instead of citation, we utilize the academic networks, in virtue of their available and abundant academic information, to evaluate the scientific impact of scholars in this paper.  ...  Considering the diverse research topics, Amjad et al. [33] measured the impact of scholarly entities by the topicbased heterogeneous rank in academic networks.  ...

Knowledge heterogeneity and social network analysis – Towards conceptual and measurement clarifications

Mohamed El Louadi
2008 Knowledge Management Research & Practice  
This literature review highlights some Social Network Analysis (SNA) concepts applicable to the study of organizational knowledge and, more particularly, to knowledge heterogeneity.  ...  SNA applied to knowledge management thus seems a stimulant for future research in the fields of management.  ...  Buskens (1998) used this measure to evaluate the heterogeneity of a trust network. But several other measures of heterogeneity are available in the literature.  ...
