Given a large collection of transactions containing items, a basic common association rules problem is the huge size of the extracted rule set. Pruning uninteresting and redundant association rules is a promising approach to solve this problem. In this paper, we propose a Condensed Representation for Positive and Negative Association Rules representing non-redundant rules for both exact and approximate association rules based on the sets of frequent generator itemsets, frequent closed itemsets, maximal frequent itemsets, and minimal infrequent itemsets in database B. Experiments on dense (highly-correlated) databases show a significant reduction of the size of extracted association rule set in database B.
给定包含项目的大量事务集合,一个基本的常见关联规则问题是提取的规则集的规模太大。对无兴趣和冗余的关联规则进行修剪是解决这一问题的一种很有前途的方法。在本文中,我们基于数据库B中的频繁生成项集、频繁封闭项集、最大频繁项集和最小不频繁项集的集合,提出了一种表示精确和近似关联规则的非冗余规则的正负关联规则的精简表示。在密集(高相关)数据库上的实验表明,数据库B中提取的关联规则集的大小显著减小。

Predicting E-commerce Item Sales With Web Environment Temporal Background 基于Web环境时间背景的电子商务商品销售预测
IF 7.9 3区 管理学 Q1 COMPUTER SCIENCE, INFORMATION SYSTEMS Pub Date : 2021-01-01 DOI: 10.52825/bis.v1i.37

In this paper, we study the effect of Web environment temporal background in pre-dicting e-commerce item sales, especially  those in temporary sales. Temporary sales nowadaysare a popular strategy for quickly clearing inventories. For traditional  recommender systems,predicting the sales of an item is done based on its past purchase records. For temporarysales items, however, such records are not available. In order to make recommendation forsuch items, contextual information, such as product descriptions, is usually used. We investi-gate whether temporal background in the Web environment can be additional useful contextualinformation in recommender systems. It is assumed that items consistent with the temporalbackground would have higher demands. We propose a method for representing the temporalbackground using word embeddings of e-commerce activities and social media data, and eval-uate their effect on sales prediction. Through empirical analysis with real-world data, we foundthat temporal background does have positive effects for sales prediction. The findings in thispaper can be conveniently incorporated into future recommender system designs.
本文研究了网络环境时间背景对电子商务商品销售,特别是临时销售的预测作用。目前,临时销售是快速清空库存的一种流行策略。对于传统的推荐系统,预测商品的销售是基于其过去的购买记录。然而,对于临时销售项目,没有这样的记录。为了推荐这些商品,通常会使用诸如产品描述之类的上下文信息。我们研究了Web环境中的时间背景是否可以作为推荐系统中额外有用的上下文信息。假设符合时间背景的项目会有更高的要求。我们提出了一种使用电子商务活动和社交媒体数据的词嵌入来表示时间背景的方法,并评估了它们对销售预测的影响。通过对现实数据的实证分析,我们发现时间背景确实对销售预测有正向影响。本文的研究结果可以方便地纳入未来的推荐系统设计中。

There is an ongoing discussion about the effectiveness of social media usage on the ability of people to recover from the crisis. However, the existing social media crisis communication models could not address the dynamic feature of social media users and the crisis, respectively. Therefore, the objective of this study is to conduct a preliminary investigation of the social media crisis communication model for building public resilience. Thus, 34 items were generated from the literature concerning the crisis, crisis response, social interaction, and resilience. The items were validated by three experts via content validity index and modified kappa statistics. After passing the validation test, the instruments were pre-tested by 32 participants. The reliability of the items was analyzed using Cronbach’s alpha. Also, the model fits and mediation were examined by the regression model, and the hypotheses were independently assessed in process macro models. Based on the result obtained, each of the constructs satisfied the internal consistency requirement; crisis (0.743), crisis response (0.724), social media interaction (0.716), and resilience (0.827). Furthermore, the result also indicates that the regression model is a good fit for the data. The independent variables statistically significantly predict the dependent variable, p < 0.05. Also, the result of the process macro models indicates that all the hypotheses are independently supported.
关于社交媒体使用对人们从危机中恢复能力的有效性,人们正在进行讨论。然而,现有的社交媒体危机传播模式并不能分别解决社交媒体用户和危机的动态特征。因此,本研究的目的是对构建公众弹性的社交媒体危机传播模式进行初步调查。因此,从文献中产生了34个关于危机、危机反应、社会互动和心理弹性的项目。问卷由三位专家通过内容效度指数和修正kappa统计量进行验证。仪器通过验证测试后,由32名参与者进行预测试。问卷的信度采用Cronbach’s alpha进行分析。通过回归模型检验模型的拟合和中介作用,并在过程宏观模型中对假设进行独立评估。根据得到的结果,每个构造都满足内部一致性要求;危机(0.743)、危机应对(0.724)、社交媒体互动(0.716)、弹性(0.827)。此外,结果还表明回归模型与数据拟合良好。自变量预测因变量有统计学意义,p < 0.05。此外,过程宏观模型的结果表明,所有假设都是独立支持的。
