A Survey on Community Detection Methods in Social Networks
Статья научная
A social network is a social structure made up of a set nodes, which represents social actors (such as people, organizations), and edges or lines represents relationship between these nodes or actors. Social networks have important roles in the dispersal of information and innovation, the analysis of such networks, attracted much attention in the research area. The analysis of social network can be done as a whole, which means the representations of all of its actors and identification of structures, present in that social network, that lead to the presence of communities. In the method of community detection, the main aim is to partition the network into dense regions of the graph, and those dense regions typically correspond to entities which are closely related, and can hence be said to belong to a community. In any complex network, communities are able to exchange and offer information because members in one community have similar tastes and desires. The determination of such communities is useful in the context of a variety of applications in social-network analysis, including customer segmentation, recommendations, link inference, and vertex labeling and influence analysis. This paper presents a survey on community detection approaches, which have already been proposed, and also discussing the type of social networks on which those proposed approaches are applicable. This survey can play a significant role in the analysis and evaluation of community detection approaches in different application domains.

A Web Based Application for Sentiment Analysis
Статья научная
Sentiment analysis, also known as opinion mining, is referred to the studying and analyzing of people's opinions, emotions, sentiments, appraisals, evaluations and attitudes about an entity like an organization, product, service, issue, individual, event, topic, etc. and about their properties. It denotes a major problem part. While in Technical industry, the name, sentiment analysis is generally used, but in academic institutions, both terms, 'sentimental analysis' and 'opinion mining' are frequently used. They, unitedly represent the unique field of study. The term 'sentiment analysis' was first appeared in (Nasukawa and Yi, 2003) probably, and the term opinion mining was first appeared in (Dave, Lawrence and Pennock, 2003). In spite of the previous researches on sentiments and opinions published earlier, they become more prominent after this date. Opinion mining and its related fields, for example, estimations, feelings, assessments, and states of mind are the subjects of investigation of slant examination and sentiment mining. The commencement and quick development of the field agree with those of the online networking on the Web, e.g., audits, gathering dialogs, web journals, microblogs, Twitter, and interpersonal organizations, in light of the fact that without precedent for mankind's history, we have an enormous volume of stubborn information recorded in computerized frames. We are working on accessing data from various data sources available online, including the various social networking sites, blogs or forums available. By using the provided APIs (of the respective site) and the web crawler mechanism, we will generate the outcomes and use them as a representation for users. Users can access the data represented in the forms of graphs and charts to analyze the behavior of the public on a particular brand, topic, issue or product.
