Article
Full-text available
Consumers read online reviews to decide whether to buy a product. Extensive research examines what makes a single review helpful or credible, yet there is very limited understanding of how a collection of reviews facilitates purchase decisions. Such understanding is critical because consumers rarely consult all reviews or a single review. They ofte...

Evidence-based management (EBMgt) concerns making complex managerial decisions by combining the decision maker’s knowledge and experience with scientific knowledge. A major obstacle to this practice is the lack of support. In this paper, we employ design science to develop an ensemble of conceptual, information and IT artefacts that support EBMgt....
Conference Paper
Full-text available
This paper focuses on inconsistency among a set of reviews and explores how, why, and when the presence of cross-review incoherence influences consumers' purchase deferral-their likelihood of making a "buy/not buy" decision immediately after consulting the reviews or deferring it until after obtaining more information. Based on the cognitive disson...

Innovation requires organizations to tap into the knowledge and creativity of teams. However, teams are confronted with massive amounts of data and information, necessitating a broad set of knowledge, methodologies, and approaches to solve problems and innovate. Consequently, team composition has become a critical challenge. Recent advances in arti...

Idea selection is a critical activity in open innovation crowdsourcing projects. Yet, the generation of vast amounts of ideas makes it cognitively challenging to identify the subset of ideas that are worthy of further consideration. We conducted an experiment to explore the influence of idea quantity and idea homogeneity on idea selection outcomes...

Computer-supported collaborative learning (CSCL) is widely adopted in industry learning, but it still faces challenges, including low participation, distraction, and learning inefficiency. In our study, we follow the design science research method to develop artifacts (a process and discussion platform) to address these CSCL challenges. Collaborati...

The popularity of online learning is growing exponentially. Accordingly, it is critical to understand how we can facilitate the learning experience for users in these unique online environments. Past research consistently finds that one important antecedent of online learning outcomes is social presence. However, there is limited research related t...
Article

Open innovation crowdsourcing enables online crowds to quickly generate a plethora of creative ideas. A key challenge is the convergence of ideas for further consideration from massive numbers of candidate ideas with diverse quality. Based on Cognitive Load Theory, we executed a laboratory experiment to test the associations between three types of...

Many governments and organizations recognize the potential of open innovation (OI) models to create value with large numbers of people beyond the organization. It can be challenging , however, to design an effective collaborative process for a massive group. Collaboration engineering (CE) is an approach for the design and deployment of repeatable c...

Advances in artificial intelligence (AI) technologies have inspired businesses and researchers to identify new ways in which AI can improve our way of life. One such quest lies in giving AIs complex human capabilities-like leadership. We take the first step towards that goal and propose a pattern-based approach to leadership. We argue that leadersh...
Conference Paper
Full-text available
A single review is rarely sufficient for consumers to make a purchase decision. While consumers typically consult a set of reviews, scant attention has been paid to the helpfulness of a review set. Moreover, it is generally assumed that the helpfulness of a review set can be easily determined by averaging the individual reviews' helpfulness evaluat...

The integration of crowdsourcing in behavioral research in the IS field offers several advantages and opportunities. This paper builds on prior study, employing a design science research (DSR) paradigm to design, develop and evaluate a tool that assists researchers in adopting crowdsourcing when testing theory about behavioral phenomena. The propos...

What if artificial intelligence (AI) machines became teammates rather than tools? This paper reports on an international initiative by 65 collaboration scientists to develop a research agenda for exploring the potential risks and benefits of machines as teammates (MaT). They generated 819 research questions. A subteam of 12 converged them to a rese...

The selection of good ideas out of hundreds or even thousands has proven to be the next big challenge for organizations that conduct open idea contests for innovation. Cognitive load and attention loss hinder crowds to effectively run their idea selection process. Facilitation techniques for the reduction and clarification of ideas could help with...

Full-text available
Over the past decades, user engagement has become central to product success more than ever before. However, while engagement has been studied extensively in various disciplines, these bodies of knowledge are siloed. One indication of this separation is that there is no existing user engagement measure that can be used consistently and reliably acr...

Engagement on online learning platforms is essential for user retention, learning, and performance. However, there is a paucity of research addressing latent engagement measurement using user activities. In this work in progress paper, we present a novel engagement score consisting of three sub-dimensions -cognitive engagement, emotional engagement...

Crowdsourcing has become a popular and well ­adopted problem­ solving approach for organizations. An important challenge in crowdsourcing projects is the crowd evaluation and selection of promising ideas from a pool of generated ideas. In this study, we aim to conduct a lab experiment to test the effect of information quantity and information distr...
Conference Paper
