A new edge betweenness measure using a game theoretical approach: an application to hierarchical community detection
Daniel Gómez, Javier Castro, Inmaculada Gutiérrez +1
In this paper we formally define the hierarchical clustering network problem (HCNP) as the problem to find a good hierarchical partition of a network. This new problem focuses on t…
Auctions: a new method for selling bbjects with bimodal density functions
Javier Castro, Rosa EspÃnola, Inmaculada Gutiérrez +1
In this paper we define a new auction, called the Draw auction. It is based on the implementation of a draw when a minimum price of sale is not reached. We find that a Bayesian Nas…
Community detection problem based on polarization measures:an application to Twitter: the COVID-19 case in Spain
Inmaculada Gutiérrez, Juan Antonio Guevara, Daniel Gómez +2
In this paper, we address one of the most important topics in the field of Social Networks Analysis: the community detection problem with additional information. That additional in…
Multiple bipolar fuzzy measures: an application to community detection problems for networks with additional information
Inmaculada Gutiérrez, Daniel Gómez, Javier Castro +1
In this paper we introduce the concept of multiple bipolar fuzzy measures as a generalization of a bipolar fuzzy measure. We also propose a new definition of a group, which is base…
From fuzzy information to community detection: an approach to social networks analysis with soft information
Inmaculada Gutiérrez, Daniel Gómez, Javier Castro +1
On the basis of network analysis, and within the context of modeling imprecision or vague information with fuzzy sets, we propose an innovative way to analyze, aggregate and apply…
Calculating the interaction index of a fuzzy measure: a polynomial approach based on sampling
Inmaculada Gutiérrez, Javier Castro, Daniel Gómez +1
In this paper we address the problem of fuzzy measures index calculation. On the basis of fuzzy sets, Murofushi and Soneda proposed an interaction index to deal with the relations…
