Community detection aims to partition a set of nodes with more similarities in the set than out of it based on different criteria like neighborhood similarity or vertex connectivity. Most present day community detection methods principally concentrate on the topological structure, largely ignoring the heterogeneous properties of the vertex. This pa...

In this article, a novel general type-2 fuzzy community detection model is presented based on different interactions in multilayer graphs to detect communities in a graph with an interaction between nodes, called a multiplex graph considering both structural and attribute similarities. The focus of this model is mostly on the uncertainty related to...

In community detection problems, a noticeable problem is to defining the number of communities determined by experts or validity indices, most of which determine the shortest or longest distance between clusters’ centers or objects. However, they may not come up with good outcomes especially when the centers of clusters are close together. Most ava...

Ontology-based similarity measures have received much importance in recent years. In many real-world cases, the domain considered in the ontological similarity assessment consists of uncertainty or incomplete information. Such vagueness has led to the successful implementation of fuzzy ontology (FO)-based similarity measures. Despite various applic...

This paper mainly aims to identify communities with different interactions between nodes in complex networks. Community detection algorithms partition vertices into densely-connected components in a complex network. In recent researches, a node is related to multiple aspects of relationships resulting in new challenges in social networks. The two a...

The current study aims to investigate the way married women living in Tehran face with disruption of sense of tranquility in marital life. This research has been done using grounded theory method and deep interview technique. As a result of encounter with disruption of sense of tranquility, which is the result of the gap between the assets and dema...

Assessing semantic similarity is a fundamental requirement for many AI applications. Crisp ontology (CO) is one of the knowledge representation tools that can be used for this purpose. Thanks to the development of semantic web, CO-based similarity assessment has become a popular approach in recent years. However, in the presence of vague informatio...

The aim of this research which has been conducted using the grounded theory is to investigate the women's strategies for achieving peace in marital life and its consequences. The data were collected through in-depth interviews with sixty married women living in the city of Tehran and then they were analyzed with the help of theoretical coding. The...

The aim of this research is to study the process which shapes women’s experience of tranquility feeling in marital life. This study was fulfilled by the grounded theory method and data was gathered through in-depth interviews with 60 married women in Tehran, and were analyzed by theoretical coding. The main purpose of marriage is to achieve tranqu...

The purpose of this paper is to examine the status of the preparedness within emergency response team (ERT) in a refinery. Preparedness was investigated through trust and coordination relationships. Social network analysis as a quantitative approach was utilized in this research. To do this, social network analysis (SNA) indicators including densit...

The main goal of this paper is to present a clustering model to identify duocentric communities in the complex networks. A duocentric community is built around two central nodes which are as close as possible to other nodes, while the central nodes are connected enough to each other to shape the center of the community. To detect such communities,...

In this paper, a fuzzy graph clustering model is presented to identify overlapping communities in a complex network. A center-based fuzzy clustering model is developed based on the possibilistic c-means clustering model, and the distance measure is defined based on the similarity to the clusters’ centers. The performance of the clustering process i...

The purpose of this paper is Meta-analysis of audit Committee independence and financial reporting quality. In spite of general expectation for positive relationship between audit committee independence and financial reporting quality, the empirical researches reveal several inconsistence conclusions. So, we conduct a meta-analysis of the associati...

Mutual help among pastoralists plays a key role in herding in rural Iran where pastoralists share a rich knowledge of dairy production. Nariyan village, located in the Taleghan region in Northern Iran, was chosen for this study on local traditions of the dairy production chain because it is still largely based on reciprocal sharing of labour and mi...

The purpose of this study was to examine the cohesions status of the coordination within response teams in the emergency response team (ERT) in a refinery. For this study, cohesion indicators of social network analysis (SNA; density, degree centrality, reciprocity, and transitivity) were utilized to examine the coordination of the response teams as...

Predicting missing links and links that may occur in the future in social networks is an attention grabbing topic amid the social network analysts. Owing to the relationship between human‐based system and social sciences in this field, granular computing can help us to model the systems more effectively. The present study aims to propose two new si...

This paper presents a new prototype of fuzzy type-2 clustering entitle Dual Center Fuzzy Type-2 Clustering based on possibilistic c-means(PCM). We mainly focus on uncertainty associated with the cluster centers and define a pair of points as center for each cluster. This model can recognize clusters with asymmetric shape. The results of proposed mo...

In this paper, a new prototype for fuzzy type-2 clustering is proposed. The proposed model considers ellipsoid shape for clusters and ellipsoid focal vectors are basis for measuring the distance from clusters, instead of cluster centers. Therefore, the degrees of belonging to clusters are defined as interval fuzzy type-2 sets indicated by the upper...

A fuzzy rule-based expert system is developed for evaluating intellectual capital. A fuzzy linguistic approach assists managers to understand and evaluate the level of each intellectual capital item. The proposed fuzzy rule-based expert system applies fuzzy linguistic variables to express the level of qualitative evaluation and criteria of experts....

The aim of this research is to study the outcomes of emotional divorce and strategies to deal with it, and is fulfilled by the method of grounded theory. The data were gathered through in-depth interviews with 20 women who visited one of the counseling centers in Tehran, and are analyzed by theoretical coding. In these interviews, women expressed t...

Our aim in this article is to study emotional divorce from the point of view of women. We use the grounded theory method and focus on explicating the social processes which shape women’s experience of emotional divorce. Data were collected through in-depth interviews with 20 women who visited one of the consulting centers in Tehran. In these interv...

Weblog is a personal medium in which bloggers can present their needs, believes, and values, free from the constraints of real world and social barriers that rule over other media. By usingqualitative content analysis and Schwartz’s value inventory, this research attempts to explore the kinds of values expressed in weblogs of Iranian bloggers. Find...

Through the emergence of information and communication technologies and customer-oriented approaches in business and industry, for achieving competitive advantages and in order to remain at the top in every business, more and responsive supply chain systems are required. The next generation of supply chain systems must be agile, adaptive, cooperati...

The Internet has become the fastest growing electronic technology in world history. The rapid evolution of any technology naturally raises questions about both its potential benefits and possible negative consequences. One of the main issues of concern is the effect Internet is having on interpersonal relationships. This paper investigates the infl...

This paper examines the characteristics of middle class Tehranis’ networks, based upon a survey of 318 individuals from the 159 households. The results show that women and men have similar-size networks. However, their networks differ substantially in gender composition, with each having almost two-thirds of network members of their own gender. Men...
