摘要：As a result of advances in data mining, more and more empirical studies in the social sciences apply classification algorithms to construct independent or dependent variables for further analysis via standard regression methods. In the classification phase of these studies, researchers need to subjectively choose a classification performance metric for optimization in the standard procedure. No matter which performance metric is chosen, the constructed variable still includes classification er...

摘要：Systems based on artificial intelligence (AI) increasingly support physicians in diagnostic decisions. Compared with rule-based systems, however, these systems are less transparent and their errors less predictable. Much research currently aims to improve AI technologies and debates their societal implications. Surprisingly little effort is spent on understanding the cognitive challenges of decision augmentation with AI-based systems although these systems make it more difficult for decision m...

摘要：The prevalence of consumers sharing their purchases on social media platforms (e.g., Instagram and Pinterest) and the use of this information by potential future consumers have substantial implications for online retailing. In this study, we examine how product characteristics and the type of information provider jointly impact purchase decisions in a social network setting. We first propose an analytical observational learning framework integrating the impact of product differentiation and so...

摘要：This research develops a microeconomic model to study the impact of support forums on the software industry. Motivated by the rapid growth of forums such as Stack Exchange, Quora, and Yahoo! Answers, we examine what impact they could have on a software vendor's pricing strategy. Because these forums provide an alternative, free source for obtaining software support, one might suspect that the shadow competition from them would eat into the profit the vendor makes from selling support services....

摘要：Over the past decades, research on online book reviews has inundated academic circles with numerous theoretical reflections and empirical manifestations aimed at explaining the effects of such resources on business performance. Yet, these studies succumbed to the conventional pitfall of assuming that consumers write reviews only after they fully read the book that they purchased. A recent industry report revealed that although many individuals initiate book reading, only a few finish them. Wit...

摘要：Digital technologies have led to the emergence of many platforms in our economy today. In certain platform networks, buyers in one market purchase services from providers in many other markets, whereas in others, buyers primarily purchase services from providers within the same market. Accordingly, network interconnectivity-which measures the degree to which consumers in one market purchase services from service providers in a different market-varies across different industries. We examine how...

摘要：The proliferation of media platforms allows marketers to gauge con- sumers' opinions toward brands directly from online word of mouth (WOM). In this paper, we exploit a large-scale television program (the Super Bowl 2016) and exogenous game events that may cause a positive emotional context for fans of the winning team while creating a negative emotional context for fans of the losing team to investigate the impact of television-program-induced emotions on viewers' online WOM behavior toward a...

摘要：Customer misbehavior is a serious and pervasive problem in firm-sponsored social media, yet prior studies provide limited insight into how firms should detect and manage it. To address this gap, we first develop a data science approach to detect customer misbehavior on social media and then devise intervention strategies to deter it. Specifically, we build on natural language processing and deep learning techniques to automatically detect customer misbehavior by mining customers' social media ...

摘要：Given the limited research into the impact of social media on offline sales of durable goods, this study examines the dynamic relationships between firm-generated content (FGC), user-generated content (UGC), traditional media, and offline light vehicle sales. Data were collected from the official Facebook and Twitter pages of 30 U.S. car brands from 2009 to 2015. We utilized a panel vector autoregressive model to investigate the dynamic relationships among multiple time series variables while ...

摘要：The goal to continually reduce operating costs while meeting computational needs is common to all modern organizations that use cloud computing. We study the problem of selecting computing resources with the goal of minimizing the total rental cost of completing a computing task in the presence of a time constraint. The problem is formulated as a scheduling problem that assigns computing resources to time periods of the planning horizon (time available to complete a single computing task). Thi...
