With the exponential developments of social network, their fundamental role as a medium to spread information, ideas, and influence has gained importance. It can be expressed by the relationships and interactions within a group of individuals. Therefore, some models and researches from various domains have been in response to the influence maximization problem for the effects of "word of mouth" of new products. For example, in reality, more than two related social groups such as commercial companies and service providers exist within the same market issue. Under such a scenario, they called social adversaries competitively try to occupy their market influence against each other. To address the influence maximization (IM) problem between them, we propose a novel IM problem for social adversarial players (IM-SA) which are exploiting the social network attributes to infer the unknown adversary's network configuration. We sophisticatedly define mathematical closed form to demonstrate that the proposed scheme can have a near-optimal solution for a player.

Online social networks(OSN) are very popular nowadays. As OSNs grows, the commercial markets are expanding their social commerce by applying Influence Maximization. However, in reality, there exist more than two players(e.g., commercial companies or service providers) in this same market sector. To address the Influence Maximization problem between adversaries, we first introduced Influence Maximization against the social adversaries' problem. Then, we proposed an algorithm that could efficiently solve the problem efficiently by utilizing social network properties such as Betweenness Centrality, Clustering Coefficient, Local Bridge and Ties and Triadic Closure. Moreover, our algorithm performed orders of magnitudes better than the existing Greedy hill climbing algorithm.

This paper identifies what the theoretical similarities and differences are in the concept of Sangsaeng held by Zhuxi (1130~1200) and Jeungsan (1871~1909). Human beings cannot live alone. For humans to survive, they must live with others. However, humans have an infinite desire not only for survival but also for material things, honor, and power. In other words, humans, on the one hand, seek harmony and symbiosis for survival, and on the other, constantly confront, conflict and compete with one another to satisfy their infinite desires. Thus, human-to-human interrelationship is not a co-prosperity that creates partnerships for harmony but one of adversaries within competition that must be fought and defeated. At the same time, humans can achieve harmony and cooperation by overcoming their infinite desires and realizing morality. Therefore, various social problems that originate from competitive structure, which are dominated by confrontation and conflict, can be solved through human effort and reflection, so that humans can focus on solving social problems by mobilizing their own wisdom. Jeungsan emphasized Sangsaeng as mutual beneficence and it became one of the creeds of Daesoon Thought. In the Neo-Confucianism of Zhuxi, there is an ideology of Sangsaeng as co-prosperity and this is comparable to mutual beneficence in Daesoon Thought. In Zhuxi's terminology it is called 'In (仁), humanity.' In Neo-Confucianism, a harmonious world is achieved by loving people and caring for and nurturing all things when the principles of humanity are realized. This means that when the principle of co-prosperity is realized in Daesoon Thought, there will be no conflict or grudges, and only an acquired vision of reconciliation and mutual beneficence will be achieved. Zhuxi also emphasizes the realization of humanity (cheonli) by eliminating self-interest. At this time, the relationship between humanity and 'self-interest' is similar to the relationship between the mutual beneficence and grievances in Daesoon Thought. Just as the principle of 'In' fosters love among people and the benefit of things immediately after self-interest is removed, the principle of mutual beneficence is realized immediately after grudges are resolved. This achieves an endless of paradise on earth.
