Neeraj Kanger, Gourav Bathla
2017 Indian Journal of Science and Technology  
Findings: The results show that with Neural Network and Fuzzy Logic performs very well in recognizing the emotional polarity of the sentences.  ...  Objectives: To find out sentiment of people about a particular thing or objects and to classify these sentiments.  ...  In the last overall polarity of the text is calculated. If the polarity of data is positive, it is positive sentence and if polarity is negative it is negative sentence.  ...

Polarization and Belief Convergence of Agents in Strongly-Connected Influence Graphs [article]

Mário S. Alvim
2020 arXiv   pre-print
We describe a model for polarization in multi-agent systems based on Esteban and Ray's classic measure of polarization from economics.  ...  Finally, we show that polarization does not necessarily vanish in weakly-connected graphs, and illustrate the model with a series of case studies and simulations giving some insights about polarization  ...  As a step further, here we consider a refinement of the model that can capture bias not only towards agents, but towards opinions themselves.  ...

A Weighted Balance Model of Opinion Hyperpolarization

Simon Schweighofer, Frank Schweitzer, David Garcia
2020 Journal of Artificial Societies and Social Simulation  
In this paper, we explain the emergence of hyperpolarization, i.e., the combination of extremeness and correlation between issues, by developing a new theory of opinion formation called "Weighted Balance  ...  Polarization is threatening the stability of democratic societies. Until now, polarization research has focused on opinion extremeness, overlooking the correlation between di erent policy issues.  ...  At each time step t, all N agents are selected in random order (thus, a single time step consists of N interactions).  ...

A Multi-Agent Model for Polarization under Confirmation Bias in Social Networks [article]

Mário S. Alvim, Bernardo Amorim, Sophia Knight, Santiago Quintero, Frank Valencia
2021 arXiv   pre-print
We describe a model for polarization in multi-agent systems based on Esteban and Ray's standard measure of polarization from economics.  ...  Agents evolve by updating their beliefs (opinions) based on an underlying influence graph, as in the standard DeGroot model for social learning, but under a confirmation bias; i.e., a discounting of opinions  ...  Hunter [18] introduces a logic of belief updates over social networks where closer agents in the social network are more trusted and thus more influential.  ...

Estimation of Interpersonal Relationships in Movies

Yuta OHWATARI, Takahiro KAWAMURA, Yuichi SEI, Yasuyuki TAHARA, Akihiko OHSUGA
2016 IEICE transactions on information and systems  
As a way to analyze the movies, we propose a method of estimating interpersonal relationships of the characters, using a machine learning technique called Markov Logic Network (MLN) from movie script databases  ...  The MLN is a probabilistic logic network that can describe the relationships between characters, which are not necessarily satisfied on every line.  ...  Markov Logic Network The MLN is a probabilistic extension of finite first-order logic that makes up the disadvantages of all the other Markov Network and first-order logic [10] .  ...

A New Framework for ABMs Based on Argumentative Reasoning [chapter]

Simone Gabbriellini, Paolo Torroni
2014 Advances in Intelligent Systems and Computing  
This paper is an extended version of the short paper accepted by AAMAS 2013 [14] 1 The relevance of logic in social simulations is an open issue, with both detractors and supporters [10] .  ...  We argue that this approach can be beneficial in social simulations, allowing for a better representation of agent reasoning, that is also accessible to the non computer science savvy, thus filling a gap  ...  There is already a plea for the use of logic-related approaches in ABM [25] , but we are not aware of any previous ABM that uses argumentation to investigate social phenomena.  ...
