Social commerce as a new paradigm of commerce has been considered for about a decade. The first attempt to apply this paradigm is to examine its acceptance process. In this research, social commerce acceptance studies have been reviewed with primary and secondary search strategies. The main purpose of this research is to examine the acceptance process from different perspectives and to analyze the research gap that paves the way for future research in this field. Survey perspectives include focus on acceptance steps, basic theories used, focus on value creation, extent of customer engagement, focus on innovation, type of media used, geographical focus, type of business transactions concerned, their influential factors, thematic focus and applied focus area, research methods used, data analysis tools and statistical samples. Accordingly, 203 articles were reviewed with two approaches: quantitative analysis and gap analysis. Quantitative analysis of studies showed that acceptance technology as the highest theories, social networks as most platforms, trust as the most widely used factor, Asia as most continental geographical focus, China and the United States as the most geographical focus of the country. Based on the gap analysis, service-oriented businesses, qualitative methods and modeling, focusing on e-commerce platforms and equipping them with social commerce constructs, and focusing on business-to-business transactions were identified as research gaps.

Telegram is a cloud-based messenger with more than 500 million monthly active users. Telegram's features include the creation of supergroups, channels, bots, and secret chats that provide users with more capabilities than a messenger. Telegram is used as a social network in Iran; but it does not offer all the features of a social network, including finding a collection of users. Finding users is very useful for marketers to find the target audience. In this paper, a method in two parts is presented by users' communication graph. The first part is based on graphs and model groups based on the percentage of subscriptions with incoming users. The second section ranks the groups based on the number of managers. The data of this study includes information about 70 million users and 700,000 supergroups in Telegram. The information obtained has been crawled by the IdeKav System, and it is worth noting that this information has been obtained quite legally by the tool provided by Telegram to the public. In this article, the proposed method is evaluated based on popular groups in Telegram. Popular groups are groups in which a single topic is discussed. In this paper, the evaluation by popular Telegram groups has been done by two categories of validation and test, and the results of experimental experiments have shown the repetition of the results and the integrity of the proposed method. The proposed method with the aim of covering the whole graph in two parts has shown the effectiveness of the suggestions and reduction of forecasting error compared to the previous three studies.

Has been for a long time, effectiveness considered by organizations as a measure of achieving the goals of stakeholders. Now, audience are the key stakeholders of media and the measure of effectiveness is their goals.
