Fundamental changes occurred in the society and economy since the nineteenth century has clearly reflected in the development of our communities. Consumption communities which had not been previously existed came to the existence by the development of mass media especially Web 2.0 and modern marketing. As a result; people are increasingly taking their identity tied to their brands. On the other hand, the market in the twenty-first century is dominated by advanced communication technology and e-commerce and hence, virtual brand communities are rapidly expanding. With regards to the above, in this study factors affecting participation in such communities are identified. The research method used is survey and the population consisted of those customers who are the members of virtual communities. Data were collected from 408 members of these communities. In order to test the hypotheses related to the components of the model, confirmatory factor analysis and structural equation modeling were used. The study findings suggest that four factors that is: factors related to the brand, social factors, factors related to the product, and functional factors are affecting participation in virtual brand communities.

Learning logic of exceptions is a considerable challenge in data mining and knowledge discovery. Exceptions are the rare phenomenon with positive unusual behavior in a database. Creating an efficient framework to increase the reliability in the detection of exceptions in the knowledge and learning is quite important. This paper presents a novel framework to promote the confidence to a limited number of records (exceptions) for effective learning of exceptions. In this study, a new approach based on the abnormality theory and computing theory is presented to detect exceptional phenomena and learn their behavior. First, Renyi entropy function is implemented to detect exceptional data which is differentiated data according to their hidden knowledge. Then, the novel E-RISE algorithm which follows bottom-up learning strategy is introduced to learn exceptional data behavior. Efficiency of the proposed model is determined by applying it to the Iran stock market data. Mining the number of 1334 stocks data points, 2.6% of them had exceptional behavior. The extracted rules represent the exceptional stocks attitudes. After that, an expert system is designed to use the extracted knowledge for recognizing new exceptional stocks. Faced with new stock, this expert system can recognize exceptions by comparing its characteristics with normal and exceptional behavior. Exceptions behave in compliance with exceptional rules or in contradiction with any normal pattern. This acquisition knowledge is the basis of exceptional portfolio selection which aims to make exceptional wealth for investors. Findings of the proposed method are compared with the outcomes of applying traditional methods as decision tree and support vector machine which is considerable. The results show the capability of the proposed method in exceptional data detection and learning their behaviors.

With the emergence of new businesses leading to the complicated and changing business environments, industrial managers and investors need tools and mechanisms to acquire a more clarified view of their business in different financial aspects in the future. The financial status of industrial firms has always had a significant analytical role and the evaluation of profitability has been conducted through the analysis of financial indicators that appear as key performance measures. In this regard, financial statements provides the stakeholders with accurate organizational status in a specific period of time. In the current research, the researchers have attempted to utilize the financial ratios as well as data mining algorithms so as to design a system that accurately predicts the net profit based on the previous performance of firms and accordingly, providing an appropriate performance analysis. The designed neural network model predicts the profit through the detection of relationships among financial ratios and previous profitability of the industrial firm.
