Social network decision making with linguistic trustworthiness based induced OWA operators
(Wiley, 2014-12)
Classic aggregation operators in group decision making such as the OWA, IOWA, C-IOWA, P-IOWA and I-IOWA have shown to be successful tools in order to provide flexibility in the aggregation of preferences. However, these ...
A Hybrid Approach to Sentiment Analysis
(IEEE, 2016)
This contribution presents a hybrid approach to Sentiment Analysis (SA) encompassing the use of semantic rules, fuzzy sets, unsupervised machine learning techniques and a sentiment lexicon improved with the support of ...
A Comparative Study on Community Detection Methods in Complex Networks
(IOS Press, 2018-03)
Community detection aims to discover cohesive groups in which people connect with each other closely in social networks. A variety of methods have been proposed to detect communities in social networks. However, there is ...
A Web Information System to Improve the Digital Library Service Quality
(2015)
To asses the quality of the services provided by a digital library, traditional measures, such as the size of its collection, have usually been utilized. However, service quality also has to be evaluated by considering ...
A self-management mechanism for non-cooperative behaviors in large-scale group consensus reaching processes
(IEEE Xplore, 2018-03-21)
In large-scale group decision making (GDM), non-cooperative behavior in the consensus reaching process (CRP) is not unusual. For example, some individuals might form a small alliance with the aim to refuse attempts to ...
Consensus modeling with probability and cost constraints under uncertainty opinions
(Elsevier, 2017-09-01)
Goal programming is often applied into uncertain group decision making to achieve the optimal solution. Exiting models focus on either the minimum cost (guaranteeing negotiation budget) or the maximum utility (improving ...
A Hybrid Approach for Supporting Adaptivity in E-learning Environments
(Emerald Group Publishing Limited, 2016-09-07)
Purpose: The purpose of this paper is to identify a framework to support adaptivity in e-learning environments. The framework reflects a novel hybrid approach incorporating the concept of the ECA model and intelligent ...
A new consensus measure based on Pearson correlation coefficient
(Proceedings of conference, 2016)
Obtaining consensual solutions is an important issue in decision making processes. It depends on several factors such as experts’ opinions, principles, knowledge, experience, etc.
In the literature we can find a considerable ...
Comparing Two Approaches for Consensus Computation in Group Decision Making Problems
(IOS press, 2018-09)
In group decision making problems, the soft consensus calculus is an important topic. Soft consensus measures are utilized to show the different agreement degrees between decisors. Using the concept of coincidence we have ...
