Online social networks (OSNs) have become so popular that it has changed the Internet to a more collaborative environment. Now, a third of the world’s population participates in OSNs, forming communities, and producing and consuming media in different ways. The recent boom of artificial intelligence technologies provides new opportunities to help improve the processing and mining of social data. In this article, an algorithm that can detect communities in the OSNs using the concepts of granular computing in rough sets is proposed. In this information model, a social network as a rough set granular social network (RGSN) is modeled. A new community detection algorithm named granular-based community detection (GBCD) is implemented. This article also defines and uses two measures, namely, a granular community factor and an object community factor. The proposed algorithm is evaluated on four real-world data sets as well as computer-generated data sets. The model is compared with other state-of-the-art community detection algorithms for the values of modularity, normalized mutual information (NMI), Omega index, accuracy, specificity, sensitivity, and $F1$ -measure. The cumulative performance of the GBCD algorithm is found to be 3.99, which outperforms other state-of-the-art community detection algorithms.

The human mind is an amazing piece of creation that can handle multiple modalities of input seamlessly and help to make sense about the surroundings. When it comes to making sense about speech, 2 main features of input are sound and vision (although there are many other components). Since not every mind is alike, some of them have trouble processing the sound aspect of input therefore vision becomes their primary source to process and understand speech. Lip reading is a skill that is used mainly by people suffering from hearing deformities and it involves large amount of language specific knowledge as well as contextual awareness i.e. using all possible visual clues that help to make sense of what the other person is saying and thus allow them to take part in the conversation. Recent breakthroughs in the field of Deep learning have clearly shown promise with models that have the ability to extract complex, intricate and generalizable patterns both in spatial as well as temporal dimension. In this paper we present FYEO (For Your Eyes Only) an end-to-end deep learning based solution that only uses vision as its single modality of input and generates a single word, character by character. The model is a modified version of the LipNet architecture from Deep Mind, to a subset of words curated from the Oxford-BBC Lip Reading in the Wild (LRW) dataset. Also, as a part of novel work FYEO is extended by adding attention mechanism for further improvement of the model’s contextual awareness and observe the model’s focus while making a prediction. The standard FYEO model achieves a length normalised test CER (character-error-rate) of 25.024%.

Centrality in social network is one of the major research topics in social network analysis. Even though there are more than half a dozen methods to find centrality of a node, each of these methods has some drawbacks in one aspect or the other. This paper analyses different centrality calculation methods and proposes a new swarm based method named Flocking Based Centrality for Social network (FBCS). This new computation technique makes use of parameters that are more realistic and practical in online social networks. The interactions between nodes play a significant role in determining the centrality of node. The new method has been calculated both empirically as well as experimentally. The new method is tested, verified and validated for different sets of random networks and benchmark datasets. The method has been correlated with other state of the art centrality measures. The new centrality measure is found to be realistic and suits well with online social networks. The proposed method can be used in applications such as finding the most prestigious node and for discovering the node which can influence maximum number of users in an online social network. FBCS centrality has higher Kendall’s tau correlation when compared with other state of the art centrality methods. The robustness of the FBCS centrality is found to be better than other centrality measures.

Online Social networks have gained much prominence in the recent years such that it has become an unavoidable means of daily communication. The element of trust in social networks has been studied ever since the inception of online social networks. Trust in online social networks is extremely fragile in nature due to the virtual connections between users in the network. The level of trustworthiness of each user in a social network varies and is usually computed using reputation level of the users. This paper focuses on identifying the features that determine the trust of a user in online social networks using benchmark datasets. We propose a new probabilistic reputation feature model that is better than the raw reputation features. The enhanced trust prediction framework has been tested and validated on three benchmark datasets namely Wikipedia election dataset, Epinions dataset and Slashdot dataset. The proposed probabilistic feature enhances the overall accuracy, F1 score, and area under the ROC for the classifier results significantly. The results have been compared with other state of the art techniques and are found to be efficient.

There has been a surge in the research of complex network analysis in the recent years. This paper engages with online social network, which is the most popular complex network in the modern world. Network communities help to understand the organization of real world networks. Accordingly, this paper proposes and validates a novel algorithm for overlapping community detection in online social networks. We focus on the stability-plasticity problem in complex networks and attempt to solve it using a Fuzzy Adaptive resonance theory inspired algorithm. The algorithm consists of two stages namely prediction stage and comparison stage. The proposed algorithms make use of network measures such as Edge betweenness, Betweenness centrality, and pair betweenness. The algorithm has been tested and compared with other algorithms using benchmark datasets, artificial datasets and real network datasets. The experimental results obtained were better than other overlapping community detection algorithms. The entropy of the proposed model has been evaluated using Overlapping normalized information, omega index, F-score and the cumulative performance value is 2.42 out of 3, which is better than other community detection algorithm.

There has been lot of research endeavours in detecting overlapping community structures in complex networks. This paper concentrates on one of the most popular complex networks of recent times—online social networks. Some of the existing methodologies in community detection for online social networks are discussed. The goal of the proposed algorithm is to solve the stability–plasticity dilemma and to suggest a new technique for detecting modular and granular overlaps in community detection. The stability–plasticity dilemma is solved using a Fuzzy ART-inspired algorithm for overlapping community detection for detecting modular and granular overlaps. The algorithm is designed by making use of network measures such as vertex betweenness, betweenness centrality, and split betweenness. The validation metrics used for testing the algorithm were sensitivity, specificity, accuracy and normalized mutual information. The algorithm has been tested and validated using benchmark datasets and real network datasets and gives a cumulative performance of 3.1/4.0.

The Cluster-head Gateway Switch Routing protocol (CGSR) uses a hierarchical network topology. CGSR organizes nodes into clusters, with coordination among the members of each cluster entrusted to a special node named cluster-head. The cluster head selection is done with the help of any of the algorithm for cluster head selection. Energy is the primary constraint on designing any Wireless Networks practically. This leads to limited network lifetime of network. Low-Energy Adaptive Clustering Hierarchy (LEACH) and LEACH with deterministic cluster head selection are some of the cluster head algorithms that enable to optimize power consumption of WSN. There are various factors like density & distance, threshold based, power efficient. Load balancing and scalability are the other factors which plays important role in the selection of Cluster head. Algorithms based on load balancing reduce communication cost to a great extent. The algorithms that this study is focused are A Density and Distance based Cluster Head, An Energy Efficient Algorithm for Cluster-Head Selection in WSNs, Consumed Energy as a Factor for Cluster Head. These three algorithms are analyzed and studied in this paper. The analysis of these algorithms gave birth to a new algorithm called EDRLEACH, which is proposed through this paper. Keywords-Cluster head,energy efficient algorithms,selection head algorithms, wireless sensor,networks.

Twitter has become one of the most widely used social networks, and its popularity is increasing day by day as the number of tweets grows exponentially each day in the order of millions. The twitter data is used widely for personal, academic, and business purpose. In this paper, we collected real-time tweets from Indian Cricket Team fans during the eight matches of ICC Cricket World Cup (CWC) 2015 (here 8 matches means the total number of games India played in CWC) using the social media twitter. We performed sentiment analysis on the tweets to test emotions of Indian Cricket Lovers. The analysis is based on the fact that the emotions of fans change frequently with each event such that when home country is batting and scoring runs, they will be happy, and for every loss of wicket they will be sad. When the team is bowling, they will be sad for ‘six’ and happy for Wickets. So when Fans are happy, they react with positive tweets and accordingly when they are sad they react with negative tweets. We analyzed that, when India is batting, people use fear, anger, nervousness, and tension which are the most frequently used negative words and words like awesome, happy, and love are the most used positive words. All emotions are entirely dependent on team India’s performance. All negative emotions are increased when opponent team hit runs or when they achieve HIGH SCORE” and is decreased when the Indian team hit runs or when they take wickets’. This paper uses tweets and captures emotions for big data analytics and analyzes emotional quotient.

Online social networks have gained importance in the past few years and have become an inseparable form of communication. People use online social networks for making friends, gaining knowledge, for entertainment and to review products. This increased influence of social networks has led to the emergence of a research area named online social network analysis. In this paper we propose a model fuzzy inference system that analyze and quantify the network measures used in the analysis of online social networks. We have divided the network measures into two classes namely connection based measures and network structure based measure. We have linked the connection based measures with the network structure based measure and have produced a fuzzy inference system for online social network analysis.

With almost all educated individuals having access to computing cum communication gadgets like mobiles, tablets, PCs, and laptops, online social networks (OSNs) have become the default means of networking among majority of individuals. OSNs have become an inseparable part of daily lives attracting more than one third of the current world population. Majority of the users enjoy the entertainment aspects of OSNs like gaming with friends from different geographic locations. Social gaming has spawned a whole new sub culture which helps users to discover and build connections with other users. Game development companies constantly try to publicise and attract new users using OSNs to enhance their revenues. In this context, we propose a new firefly inspired strategy to spread and disseminate games in OSNs and assist the gaming companies to decrease the acceptance-discontinuance anomaly. Collective behaviour in online social network is closely related to swarm intelligence techniques. We have also proposed a rewarding and efficient Firefly inspired QoS-based priority pricing model that will attract more users to play online games while using online social networks, thereby, enhancing the profits of the service providers and game developers.
