Group Degree Centrality and Centralization in Networks [PDF]
Mathematics, 2020 The importance of individuals and groups in networks is modeled by various centrality measures. Additionally, Freeman’s centralization is a way to normalize any given centrality or group centrality measure, which enables us to compare individuals or groups from different networks. In this paper, we focus on degree-based measures of group centrality and

Internet Mathematics, 2014 Given a social network, which of its nodes are more central? This question has been asked many times in sociology, psychology and computer science, and a whole plethora of centrality measures (a.k.a. centrality indices, or rankings) were proposed to account for the importance of the nodes of a network.

Sentence Centrality Revisited for Unsupervised Summarization [PDF]
Annual Meeting of the Association for Computational Linguistics, 2019 Single document summarization has enjoyed renewed interest in recent years thanks to the popularity of neural network models and the availability of large-scale datasets. In this paper we develop an unsupervised approach arguing that it is unrealistic to

Les rivages d’Istanbul : des espaces publics au cœur de la mégapole
Géographie et Cultures, 2005 The waterfronts of Istanbul offer different public spaces, used tor many practices and have a particular status in the city. New kind of spaces are now emerging, witnesses of the merchandisation processes and the search of a new urbanity. These processes

Measuring Decentrality in Blockchain Based Systems
IEEE Access, 2020 Blockchain promises to provide a distributed and decentralized means of trust among untrusted users. However, in recent years, a shift from decentrality to centrality has been observed in the most accepted Blockchain system, i.e., Bitcoin. This shift has
