ABSTRACT As video-sharing sites emerge as a critical part of the social media landscape, video viewership prediction becomes essential for content creators and businesses to optimize influence and marketing outreach with minimum budgets. Although deep learning champions viewership prediction, it lacks interpretability, which is required by regulators and is fundamental to the prioritization of the video production process and promoting trust in algorithms. Existing interpretable predictive models face the challenges of imprecise interpretation and negligence of unstructured data. Following the design-science paradigm, we propose a novel Precise Wide-and-Deep Learning (PrecWD) to accurately predict viewership with unstructured video data and well-established features while precisely interpreting feature effects. PrecWD’s prediction outperforms benchmarks in two case studies and achieves superior interpretability in two user studies. We contribute to IS knowledge base by enabling precise interpretability in video-based predictive analytics and contribute nascent design theory with generalizable model design principles. Our system is deployable to improve video-based social media presence.
随着视频分享网站成为社交媒体领域的重要组成部分,视频收视率预测对于内容创作者和企业以最小的预算优化影响力和营销推广变得至关重要。尽管深度学习支持收视率预测,但它缺乏可解释性,这是监管机构所要求的,也是视频制作过程优先排序和促进对算法信任的基础。现有的可解释预测模型面临着解释不精确和忽视非结构化数据的挑战。遵循设计科学范式,我们提出了一种新颖的精确广域深度学习(PrecWD),以准确预测非结构化视频数据和成熟特征的收视率,同时精确解释特征效应。在两个案例研究中,PrecWD的预测优于基准测试,并在两个用户研究中实现了卓越的可解释性。我们通过在基于视频的预测分析中实现精确的可解释性来贡献IS知识库,并通过可推广的模型设计原则贡献新生的设计理论。我们的系统是可部署的,以提高基于视频的社交媒体的存在。

ABSTRACT Online retailers are increasingly focused on maintaining a long-term relationship with customers, encouraging repeat visits rather than single-time purchases to increase customer lifetime value. To help retailers maximize the probabilities of customers’ revisiting and purchasing, we develop a two-stage model to better characterize and predict these two fundamental customer activities. In the first stage, we characterize the propensity of a customer revisiting the retailer’s website. In the second stage, we develop a stochastic model that predicts revisits while also incorporating individual customer heterogeneity in exerted search effort during repeated visits. This heterogeneity is based on individual customer preferences in the choice of consideration sets, product information, pricing, and the search environment. Using customer level clickstream data, we show that our approach is not only better at predicting repeat customer visits, compared to existing methods, but also explainable and managerially interpretable. Most importantly, using computationally efficient simulation-based prescriptive analytics, we leverage our modeling approach to propose practical intervention strategies that maximize the joint likelihoods of customers revisiting and purchasing at the individual customer level.
在线零售商越来越注重与客户保持长期关系,鼓励重复访问而不是一次性购买,以增加客户终身价值。为了帮助零售商最大限度地提高顾客再次光顾和购买的概率,我们开发了一个两阶段模型来更好地描述和预测这两种基本的顾客活动。在第一阶段,我们描述了客户重新访问零售商网站的倾向。在第二阶段,我们开发了一个随机模型,该模型在预测重复访问的同时也考虑了个人客户在重复访问期间所施加的搜索努力的异质性。这种异质性是基于个人客户在选择考虑集、产品信息、定价和搜索环境方面的偏好。使用客户级点击流数据,我们表明,与现有方法相比,我们的方法不仅可以更好地预测客户回访,而且可以解释和管理上可解释。最重要的是,使用基于计算效率模拟的规范分析,我们利用建模方法提出实用的干预策略,最大限度地提高客户在个人客户层面重新访问和购买的共同可能性。

ABSTRACT While venture capital firms are increasingly relying on recommendation models in investment decisions, existing startup recommendation models fail to consider the uniqueness of venture capital context, including two-sided matching between investing and investee firms and a lack of information disclosure requirements on startups. Following the design science research paradigm and guided by the proximity principle from social psychology, we develop a novel framework called SocioLink by depicting and analyzing various relations in a knowledge graph via machine learning. Our experimental results show that SocioLink significantly outperforms state-of-the-art startup recommendation methods in both accuracy and quality. This improvement is driven by not only the inclusion of social relations but also the superiority of modelling relations via knowledge graph. We also develop a web-based prototype to demonstrate explainable artificial intelligence. This work contributes to the FinTech literature by adding an innovative design artifact—SocioLink—for decision support in the investment context.
摘要尽管风险投资公司在投资决策中越来越依赖推荐模型,但现有的创业公司推荐模型没有考虑到风险投资环境的独特性,包括投资公司和被投资公司之间的双边匹配,以及缺乏对创业公司的信息披露要求。我们遵循设计科学的研究范式,以社会心理学的邻近原理为指导,通过机器学习在知识图中描绘和分析各种关系,开发了一个名为SocioLink的新框架。我们的实验结果表明,SocioLink在准确性和质量方面都显著优于最先进的创业推荐方法。这种改进不仅是由社会关系的包容性推动的,而且是由通过知识图建模关系的优越性推动的。我们还开发了一个基于网络的原型来展示可解释的人工智能。这项工作通过添加创新设计工件SocioLink为金融科技文献做出了贡献,用于投资环境中的决策支持。

ABSTRACT Popular online business directory (OBD) platforms, such as Yelp and TripAdvisor, depend on voluntarily user-submitted data about various businesses to assist consumers in finding appropriate options for transactions. Yet the crowdsourced nature of such data restricts the availability of attribute values for many businesses on the platform. Crowdsourced data often suffer serious completeness and timeliness constraints, with negative implications for key stakeholders such as users, businesses, and the platform. We thus develop a novel, deep learning–based imputation method, premised in institutional theory, to estimate missing attribute values of individual businesses on an OBD platform. The proposed method leverages a deep model architecture and considers both inter-business and inter-attribute relationships for imputations. An application to a Yelp data set reveals our method’s greater imputation effectiveness relative to prevalent methods. To illustrate the method’s practical utilities and values, we further examine the efficacy of business recommendations empowered by its imputed business attribute values, in comparison with those enabled by data imputed by benchmark methods. The results affirm that the proposed method substantially outperforms benchmarks for imputing missing attribute values and empowers more effective business recommendations. This study addresses crucial, prominent completeness and timeliness constraints in crowdsourced data on OBD platforms and offers insights for downstream applications that can improve user experiences, firm performance, and platform services.
流行的在线商业目录(OBD)平台,如Yelp和TripAdvisor,依赖于用户自愿提交的各种企业数据来帮助消费者找到合适的交易选择。然而,这些数据的众包性质限制了平台上许多企业获取属性值的可用性。众包数据通常会受到严重的完整性和及时性限制,这对用户、企业和平台等关键利益相关者都有负面影响。因此,我们在制度理论的前提下,开发了一种新颖的、基于深度学习的imputation方法,来估计OBD平台上单个企业缺失的属性值。该方法利用了深度模型体系结构,并考虑了业务间和属性间的关系。对Yelp数据集的应用表明,相对于流行的方法,我们的方法具有更高的imputation有效性。为了说明该方法的实际效用和价值,我们进一步研究了由其输入的业务属性值支持的业务建议的有效性,并将其与由基准方法输入的数据支持的业务建议进行了比较。结果证实,所提出的方法在计算缺失属性值方面大大优于基准,并提供更有效的业务建议。本研究解决了OBD平台众包数据中关键的、突出的完整性和及时性限制,并为下游应用提供了见解,可以改善用户体验、公司绩效和平台服务。

Recent years have proven to be among the most challenging on record for organizations and society at large. A global multi-year pandemic, violence resulting from polemic political discourse, and social-justice movements borne from (deadly) racial inequality are but a few examples of the major events that have changed how we work and live. The pandemic has changed where we perform our work duties and how we collaborate across space and time using technology. The political discourse has given rise to new social media phenomena like fake news and deep fake videos. The social-justice movements have put issues of diversity, equity, and inclusion front and center for many organizations. At the same time, information systems and technology have seen accelerated changes as well. Artificial Intelligence (AI) has become a mainstream application for organizations and households. Social media applications keep evolving, changing how we share information, interact with each other, and form communities. Information systems (IS) professionals versed in analytics and data science have become one of the scarcest organizational resources. Together these societal challenges and technological advances have changed how organizations and individuals create, receive, interpret, analyze, and act on information. The essence of value creation in communities and organizations is shifting as we find new work structures, new technologyhuman relationships, and new analytical techniques to find insight and extract knowledge from huge amounts of information. This special issue presents advanced research studies that share insights on new approaches, new techniques, and new understandings of how communities, organizations, and individual use information and information systems to create value The first paper focuses on a design method: “Act and Reflect: Integrating Reflection into Design Thinking,” by Thorsten Schoormann, Maren Stadtländer, and Ralf Knackstedt, demonstrates the criticality of adding a reflection lens to development methods. Specifically, the authors report on a multi-method study that includes a literature review, semi-structured interviews, a case study, and a software prototype, to develop prescriptive design knowledge on how to integrate reflection into design thinking. Their contribution to the Design Thinking discourse is significant as it accommodates and structures teams that experience divergent values, knowledge, and preferences to actively learn from their experiences and inform future design efforts. The next paper, “Formation and Action of a Learning Community with Collaborative Learning Software,” by Evren Eryilmaz, Brian Thoms, Zafor Ahmed, and Howard Lee presents a mixed-methods field study that is grounded in group cognition, knowledge building, and learning analytics to demonstrate how learning community development can be facilitated by specialized asynchronous online discussion (AOD) tools.

事实证明,近年来对组织和整个社会来说是有记录以来最具挑战性的几年。一场全球多年流行病、由论战性政治话语引发的暴力以及由(致命的)种族不平等引发的社会正义运动,只是改变我们工作和生活方式的重大事件的几个例子。疫情改变了我们履行工作职责的方式,也改变了我们如何利用技术跨越时空进行合作。政治话语引发了新的社交媒体现象,如假新闻和深度假视频。社会正义运动将多样性、公平性和包容性问题放在了许多组织的首要和中心位置。与此同时,信息系统和技术也出现了加速变化。人工智能(AI)已成为组织和家庭的主流应用。社交媒体应用程序不断发展,改变了我们共享信息、相互互动和形成社区的方式。精通分析和数据科学的信息系统专业人员已成为最稀缺的组织资源之一。这些社会挑战和技术进步共同改变了组织和个人创建、接收、解释、分析信息和对信息采取行动的方式。随着我们发现新的工作结构、新的技术人际关系和新的分析技术,从海量信息中寻找洞察力和提取知识,社区和组织价值创造的本质正在发生变化。本特刊介绍了高级研究,分享了对社区、组织和个人如何使用信息和信息系统创造价值的新方法、新技术和新理解的见解。第一篇论文聚焦于一种设计方法:Thorsten Schoormann、Maren Stadtländer,以及Ralf Knackstedt,证明了在开发方法中添加反射镜的重要性。具体而言,作者报告了一项多方法研究,包括文献综述、半结构化访谈、案例研究和软件原型,以开发关于如何将反思融入设计思维的规定性设计知识。他们对设计思维话语的贡献是重要的,因为它容纳和组织了具有不同价值观、知识和偏好的团队,以积极学习他们的经验,并为未来的设计工作提供信息。Evren Eryilmaz、Brian Thoms、Zafor Ahmed和Howard Lee的下一篇论文《协作学习软件学习社区的形成和行动》提出了一项基于群体认知、知识构建,以及学习分析,以展示如何通过专门的异步在线讨论(AOD)工具来促进学习社区的发展。作者展示了参与者在参与基于《管理信息系统杂志2023》第40卷第1、3–6期的共同创造知识的讨论时,在不同的社区层——中心层、中间层和外围层——进行操作https://doi.org/10.1080/07421222.2023.2172768

ABSTRACT Multiorganizational, multistakeholder (MO-MS) collaborations that may span organizational and national boundaries, present design challenges beyond those of smaller-scale collaborations. This study opens an exploratory research stream to discover and document design concerns for MO-MS collaboration systems beyond those of the single-task collaborations that have been the primary focus of collaboration engineering research. We chose the healthcare industry as the first target for this research because it has attributes common to many MO-MS domains, and because it faces significant challenges on a global scale, like the recent COVID-19 pandemic, for which MO-MS collaboration could offer solutions, as, for example, evidenced by the rapid collaborative development and distribution of COVID-19 vaccines. To this end, we reviewed 6,609 articles to find 100 articles that offered insights about the design of MO-MS collaboration systems, then conducted 50 semi-structured interviews in two countries with expert practitioners in the field. From those sources, we derived an eleven-category set of design concerns for MO-MS collaboration systems and argue their generalizability to other MO-MS domains. We offer exemplar probe questions that designers can use to increase the breadth and depth of requirements gathering for MO-MS collaboration systems.
多组织、多利益相关者(MO-MS)合作可能跨越组织和国家边界,呈现出比小规模合作更大的设计挑战。本研究开辟了一个探索性研究流,以发现和记录MO-MS协作系统的设计关注点,而不是那些一直是协作工程研究的主要焦点的单任务协作。我们选择医疗保健行业作为本研究的第一个目标,因为它具有许多MO-MS领域的共同属性,并且因为它在全球范围内面临重大挑战,例如最近的COVID-19大流行,MO-MS协作可以提供解决方案,例如,COVID-19疫苗的快速合作开发和分销证明了这一点。为此,我们回顾了6609篇文章,从中找到了100篇提供了关于MO-MS协作系统设计的见解的文章,然后在两个国家与该领域的专家从业者进行了50次半结构化访谈。从这些来源中,我们得出了一组包含11个类别的MO-MS协作系统的设计关注点,并论证了它们在其他MO-MS领域的普遍性。我们提供了典型的探索性问题,设计人员可以使用这些问题来增加MO-MS协作系统需求收集的广度和深度。

Leveraging Low Code Development of Smart Personal Assistants: An Integrated Design Approach with the SPADE Method 利用智能个人助理的低代码开发:一种与SPADE方法的集成设计方法

ABSTRACT Smart personal assistants (SPAs), such as Alexa for example, promise individualized user interactions owing to their varying interaction possibilities, knowledgeability, and human-like behaviors. To support the widespread adoption and use of SPAs, organizations such as Google or Amazon provide low code environments that support the development of SPAs (e.g., for Google Home or Amazon’s Alexa). These so-called low code platforms enable domain experts (e.g., business users without programming skills or experience) to develop SPAs for their purposes. However, using these platforms alone does not guarantee a useful and good conversation with novel SPAs due to non-intuitive design choices. Following a design science research approach, we propose the Smart Personal Assistant for Domain Experts (SPADE) method to address the missing link. This method supports domain experts in the development and contextualization of sophisticated SPAs for various application scenarios and focuses especially on conversational and anthropomorphic design steps. Our proof of concept and proof of value results show that SPADE is useful for supporting domain experts to create effective SPAs in different domains beyond private set-ups.
摘要智能个人助理(SPAs),例如Alexa,由于其不同的交互可能性、知识性和类人行为,有望实现个性化的用户交互。为了支持SPAs的广泛采用和使用,谷歌或亚马逊等组织提供了支持SPAs开发的低代码环境(例如,谷歌主页或亚马逊的Alexa)。这些所谓的低代码平台使领域专家(例如,没有编程技能或经验的商业用户)能够为其目的开发SPAs。然而,由于非直观的设计选择,单独使用这些平台并不能保证与新型SPAs进行有用和良好的对话。遵循设计科学研究方法,我们提出了领域专家智能个人助理(SPADE)方法来解决缺失的环节。该方法支持领域专家为各种应用场景开发和情境化复杂的SPAs,并特别关注对话和拟人化设计步骤。我们的概念验证和价值验证结果表明,SPADE有助于支持领域专家在私人设立之外的不同领域创建有效的SPA。

To support the widespread adoption and use of SPAs, organizations such as Google or Amazon provide low code environments that support the development of SPAs (e.g., for Google Home or Amazon’s Alexa). These so-called low code platforms enable domain experts (e.g., business users without programming skills or experience) to develop SPAs for their purposes. However, using these platforms alone does not guarantee a useful and good conversation with novel SPAs due to non-intuitive design choices. Following a design science research approach, we propose the Smart Personal Assistant for Domain Experts (SPADE) method to address the missing link.

ABSTRACT Teams working on creative projects, such as design thinking, mostly face complex problems as well as challenging situations characterized by uniqueness and value conflicts. To cope with these characteristics, teams usually start doing something by drawing on their current store of experiences and professional knowledge, and then (re-)assess the outcomes produced, and adjust future actions based on insights obtained during the process. In reflecting on actions, tacit knowledge is revealed that enables designers to handle challenging situations. Although there is great potential to support design thinking by adding a reflection lens, we lack guidance on how, when, and on what to perform reflection. Based on scientific and theoretical literature, semi-structured interviews, a case study and a software prototype, prescriptive design knowledge on how to integrate reflection into design thinking is deduced, which enriches the scarce body of knowledge at the intersection of reflection and (digital) design thinking.
从事创造性项目(如设计思维)的团队大多面临复杂的问题以及具有独特性和价值冲突的挑战性情况。为了应对这些特征,团队通常会利用他们当前的经验和专业知识,然后(重新)评估产生的结果,并根据过程中获得的见解调整未来的行动。在对行动的反思中,隐性知识被揭示出来,使设计师能够处理具有挑战性的情况。尽管通过添加反射镜来支持设计思维有很大的潜力,但我们缺乏关于如何、何时以及如何进行反射的指导。基于科学和理论文献、半结构化访谈、案例研究和软件原型,推导出了如何将反思融入设计思维的规范性设计知识,丰富了反思与(数字)设计思维交叉处的稀缺知识。

Blood and Water: Information Technology Investment and Control in Family-owned Businesses 血与水:家族企业的信息技术投资与控制

ABSTRACT Family-owned businesses differ in their strategic intent and behavior as they serve as a reservoir of wealth and social status for their family owners. Family-owned businesses demonstrate relatively conservative strategic decision making that aspires long-term wealth preservation and enhancement. For family owners, investments in information technology (IT) raise a predicament as they are risky, yet a long-term imperative. We propose three hypotheses that build upon the thesis that family owners combine a deep understanding of the business with a strong influence on stakeholders within and beyond the firm’s boundaries to exert strategic control in the extended enterprise. First, family ownership negatively influences IT investment, because family owners are likely to avoid investments in IT that are frivolous, reduce information asymmetry, or leave auditable digital trails. Second, the negative influence of family ownership on IT investment is weakened when a career professional is appointed in the senior-most executive position of a family-owned business. This is because professional executives strive to utilize IT for control and performance benefits, and family owners desire to use IT to monitor and control the non-family professional executive. Third, family ownership weakens the negative influence of environmental hostility on the relationship between IT investment and firm performance, as family-owned businesses incur less dynamic adjustment costs and maintain better alignment between IT and business strategy. Empirical analysis, consisting of panel regression estimations, on archival data of publicly listed Indian firms in the years 2006 to 2018 provides support for our theory that highlights how IT for control acts as a noneconomic motivation for the strategic IT behavior of firms. In doing so, we bring family ownership into the theoretical foreground for future IS scholarship. We contribute to theory and practice by advancing the nature of ownership and executive management as sources of heterogeneity in IT investment and its business value.
家族企业作为家族所有者财富和社会地位的储备,其战略意图和行为各不相同。家族企业表现出相对保守的战略决策,追求长期财富保值和增值。对于家族所有者来说,投资信息技术(IT)带来了一种困境,因为它们有风险,但又有长期的必要性。基于家族所有者对企业的深刻理解和对企业内外利益相关者的强大影响力,我们提出了三个假设,以在扩展的企业中施加战略控制。首先,家族所有权会对IT投资产生负面影响,因为家族所有者可能会避免对IT进行无谓的投资,减少信息不对称,或留下可审计的数字痕迹。第二,在家族企业中任命职业专业人员担任最高层管理职位时,家族所有权对IT投资的负面影响减弱。这是因为专业管理人员努力利用IT来控制和绩效收益,而家族所有者希望使用IT来监视和控制非家族专业管理人员。第三,家族所有制弱化了环境敌意对IT投资与企业绩效关系的负面影响,因为家族所有制企业产生的动态调整成本更低,IT与企业战略之间保持了更好的一致性。对2006年至2018年印度上市公司的档案数据进行的实证分析,包括面板回归估计,为我们的理论提供了支持,该理论强调了IT控制如何成为公司战略IT行为的非经济动机。在这样做的过程中,我们将家族所有权纳入未来IS奖学金的理论前景。我们通过推进所有权和执行管理作为IT投资及其业务价值的异质性来源的性质,为理论和实践做出贡献。

ABSTRACT Social media platforms are increasingly used during disasters. In the United States, users often consider these platforms to be reliable news sources and they believe first responders will see what they publicly post. While having ways to request help during disasters might save lives, this information is difficult to find because non-relevant content on social media completely overshadows content reflective of who needs help. To resolve this issue, we develop a framework for classifying hurricane-related images that have been human-annotated. Our approach uses transfer learning and classifies each image using the VGG-16 convolutional neural network and multi-layer perceptron classifiers according to the urgency, relevance, and time period, in addition to the presence of damage and relief motifs. We find that our framework not only successfully functions as an accurate method for hurricane-related image classification but also that real-time classification of social media images using a small training set is possible.
摘要灾难期间,社交媒体平台的使用越来越多。在美国,用户通常认为这些平台是可靠的新闻来源,他们相信第一反应者会看到他们公开发布的内容。虽然在灾难期间有办法请求帮助可能会挽救生命,但这些信息很难找到,因为社交媒体上的非相关内容完全掩盖了反映谁需要帮助的内容。为了解决这个问题,我们开发了一个框架,用于对经过人工注释的飓风相关图像进行分类。我们的方法使用迁移学习,并使用VGG-16卷积神经网络和多层感知器分类器,根据紧迫性、相关性和时间段,以及损伤和浮雕图案的存在,对每个图像进行分类。我们发现,我们的框架不仅成功地作为飓风相关图像分类的准确方法,而且使用小训练集对社交媒体图像进行实时分类也是可能的。
