Abstract

With the booming development of online marketing in social networks, it is increasingly valuable to adopt precision marketing based on user profiles by analyzing users’ behaviors and attributes. In this paper, the Least Cost Precision Marketing problem based on User Profiles in social networks (LCPM-UP problem) is proposed. Its objective is to minimize the cost to choose initial users while at least J target users described by certain user profile are influenced. Considering that users have different propagation capabilities in social networks, a novel propagation model named Limited Diffusion Independent Cascade model (LD-IC model) is presented. It is proved that the LCPM-UP problem in LD-IC model is NP-hard and the influence propagation function is submodular and monotonically increasing. Therefore, a greedy algorithm is developed for the problem. However, the greedy algorithm is too time consuming to be scalable to large networks, so the Target User Local Influence Heuristic algorithm (TU-LIH) is proposed by utilizing local influences of each node to approximate the influence propagation in LD-IC model. Extensive experiments on datasets from four real social networks demonstrate the effectiveness and efficiency of proposed algorithms.
基于社交网络用户档案的最小成本精准营销
随着社交网络网络营销的蓬勃发展,通过分析用户的行为和属性,采用基于用户档案的精准营销越来越有价值。本文提出了基于社交网络用户档案的最小成本精准营销问题(lcpmp - up问题)。它的目标是最小化选择初始用户的成本,同时至少有J个由特定用户配置文件描述的目标用户受到影响。考虑到用户在社交网络中具有不同的传播能力,提出了一种新的传播模型——有限扩散独立级联模型(LD-IC模型)。证明了LD-IC模型的lcpmp - up问题是np困难的,影响传播函数是次模的且单调递增的。为此,提出了一种贪心算法。然而,贪心算法耗时太长,无法扩展到大型网络中,因此,提出了目标用户局部影响启发式算法(TU-LIH),利用每个节点的局部影响近似LD-IC模型中的影响传播。在四个真实社交网络的数据集上进行的大量实验证明了所提出算法的有效性和效率。
