Evaluating discounts as a dimension of customer behavior analysis

Today, increased competition between organizations has led them to seek a better understanding of customer behavior through identifying valuable customers. Customers’ expectations about the price and quality of products and services play an important role in their selection process. In online businesses, competition and price differences between suppliers is high, so discounts will attract different customers. As a result, discounts and the frequency and amount of purchases can lead to better understanding of customer behavior. Customer segmentation and analysis is essential for identifying groups of customers. Hence, this study uses a model based on RFM called RdFdMd, in which d is the level of discount used to analyze customer purchase behavior and the importance of discounts on customers’ purchasing behavior and organizational profitability. The CRISP-DM and k-mean algorithm were used for clustering. The results indicate that using the R_dF_dM_d model achieves better customer clustering and valuation, and discounts were identified as an important criterion for customer purchases.     

Crowdsourcing-based semantic relation recognition for natural language questions over RDF data

ABSTRACT

Natural language query systems over RDF data need to rely on the semantic relations in query. First, we propose the new crowdsourcing model that used to produce semantic relations dataset. The model not only inherits completeness of the iterative model and accuracy of the parallel model, but also saves human resources. Second, we mine the rules of semantic relation recognition from the correlations between dependency structures and semantic relations. Third, we propose an algorithm of semantic relation recognition for natural language query over RDF data, and experiments demonstrate that it can recognize more semantic relations than existing methods.

我国政府公共危机管理问责制的完善——基于矿难行政责任追究的视角

现阶段，我国政府公共危机管理的绩效评价工作才刚刚起步，“官员问责”还存在着一些问题。在政府公共危机管理体系中，绩效评价和问责是较为薄弱的一环。文章通过对我国近几年发生的六起煤矿特别重大事故行政责任追究结果的分析，厘清我国政府公共危机管理绩效评价和问责存在的问题。在此基础上，借鉴国外政府公共危机管理绩效评价工作的做法，提出应分别从问责目标、问责主体、问责对象、问责内容、问责程序和方法、问责结果的应用等方面完善我国政府公共危机管理问责制。
