Design/methodology/approach The analysis is based on a cross-sectiona...

While it is widely recognized that value perception increases when individuals engage in making physical objects, the impact of peer presence on value perception during production or consumption has not been studied. Peer production is prevalent for information products, which are the focus of the present study. Most research to date has focused on...

We address the disparity between availability of information and its actual implementation in decisions in the context of Web Accessibility (W-A). Organizations are aware of the importance of W-A for alleviating barriers to interaction with online platforms, such as visual, motor, hearing, and cognitive impairments. Information regarding inclusion...

Research to date on the value of information has mostly focused on the consumption side of information, namely, that consumers need to experience information in order to evaluate it. When it comes to digital media, users have multiple roles. In this context, materiality is applied to assess the role that technological components play in the interac...

In this study the evolution of Big Data (BD) and Data Science (DS) literatures and the relationship between the two are analyzed by bibliometric indicators that help establish the course taken by publications on these research areas before and after forming concepts. We observe a surge in BD publications along a gradual increase in DS publications....

People often need to select, evaluate, and integrate information from diverse online sources to support decision-making processes in everyday life. Information is a product which is often available for free, but which people are willing to pay for. Free access to information can presumably facilitate greater use of information sources, thereby lead...

Value perception increases when people engage in producing physical objects. However, information differs from physical objects by being intangible and easy‐to‐copy. Information as an experience good is inherently challenging to evaluate a priori; therefore, comparing value before and after different types of experience is likely to inform theory a...

1 Abstract The study examines the interaction between crowds (the users) and task (knowledge pooling) through gamification. By probing the sensitivity of three types of crowd to various scores mechanism designs, we aim to highlight the nuance between quantity and quality of knowledge contribution. Results support the importance of choosing the righ...

Background: Application of virtual reality (VR) to rehabilitation is relatively recent with clinical implementation very rapidly following technological advancement and scientific discovery. Implementation is often so rapid that demonstrating intervention efficacy and establishing research priorities is more reactive than proactive. This study use...

The proliferation of Web-based information sources and social media draw firms' attention to these channels as sources of competitive intelligence (CI). To date, research has focused mainly on information collection techniques rather than on CI uses and its influence on firm performance. We define CI embeddedness as the extent to which management a...

The current study investigates how the game points allocation function affects quality of responses and replaying behavior in a game-for-crowds implementation. In a series of experiments, we compare between two scoring designs across two types of users: students and public. Two reward-based mechanisms differing in the mathematical function were app...

Traditionally in clinics or hospitals, it is the staff (physician, nurses, and so forth) who would check the patient's health status (e.g., blood pressure, height, weight, body temperature, and so forth). However, when mobile apps are used as the point of contact between patients and healthcare providers, the self-monitoring of health status will b...

Information sources require consumers to use them in order to evaluate their quality, meaning that they are experience goods. The value perceived before acquisition and use may be different from the value obtained by actual use. Understanding the value perception gap is likely to inform more efficient selection of information sources. The current r...

Purpose To examine the relationship between the media, through which medical information was made available (e.g. digital versus printed), and the patients’ desire to play an active part in a medical decision in an SDM or an ISDM-based process. The goal of this research was to expand knowledge concerning social and personal factors that affect and...

The current empirical study examines relationships between network measures and learning performance from a social network analysis perspective.

Widely used information diffusion models are based on the assumption that exposure to information, like exposure to a virus, is enough for it to spread. However, the diffusion of information is more complex and involves an array of decisions regarding whether to consume the information received, and upon consumption, whether to pass it on to others...

Gamification, the use of game design elements in non-game contexts to encourage a desired type of behavior, have become increasingly popular over the last few years. Gamification attempts to harness the motivational power of games, however existing motivational models for video game play focus on how a game as a whole creates experiences of fun and...

While information may carry an intrinsic, objective value, this value is not known before consumption; therefore, it is the perception of its value by the user that determines if and how it will be acquired and applied. This pre-consumption perception is followed by post-consumption experience which may shed more light on the evolution of value per...

This study examines the role of free comments given in a commercial information service through the lens of the expectation-confirmation theory and continuance. Data from a question and answer web s...

This research explores the relationship between self-presentation and perception by others as manifested explicitly through the use of tags in a people tagging system. The study provides insights relevant for the organizational context since it is based on a system implemented within IBM. We developed a detailed codebook and used it to categorize 9...

The user-centered approach to information retrieval emphasizes the importance of a user model in determining what information will be most useful to a particular user, given their context. Mediated search provides an opportunity to elaborate on this idea, as an intermediary's elicitations reveal what aspects of the user model they think are worth i...

The objective of this paper is to better understand the incentives and rewards structure in online serious games for crowds. We address the issue of feedback mechanisms with a focus on the relationship between game behavior and accumulated game scores (points). We posit that the score keeping system design is likely to inform us regarding patterns...

Prediction Markets are a family of Internet–based social computing applications, which use market price to aggregate and reveal information and opinion from dispersed audiences. The considerable complexity of these markets inhibited the full realization of the promise so far. This paper offers the P–MART classification as a tool for organizing the...

The aim of this study is to understand the effect of self-efficacy on the performance of problem solving by looking into a specific category of problems, numeric riddles. Self-efficacy, the belief in one’s own ability to act in a manner that leads to success, shapes effective performance of individuals in different areas, and varies across activiti...

Social technologies tend to attract research on social structure or interaction. In this paper we analyze the individual use of a social technology, specifically an enterprise people-tagging application. We focus on active participants of the system and distinguish between users who initiate activity and those who respond to activity. This distinct...

This study explains the application of three bibliometric tools for the exploration of the maturity of the information society as a field of research. The authors discovered a disparity between the realization of the information society in everyday life and the state of the research in the area which is at a fairly early stage of evolving into a ma...

There is general consensus that critical mass at inception ensures the sustained success of online communities. However, no clear understanding of what constitutes such a 'critical mass' exists and too few quantitative studies have been conducted into the relationship between initial online community interaction and its longer term success to draw...

Prior research has shown that social interaction is important for continuation of question-and-answer (Q&A) activity online and that it also leads to monetary rewards. The present research focuses on the link between social interaction and the value of information. Expressions of self-presentation in the interaction between askers and answerers onl...

Purpose The purpose of this paper is to propose a method for statistical inference on data from power law distributions in order to explain behavior and social phenomena associated with web‐based social spaces such as discussion forums, question‐and‐answer sites, web 2.0 applications and the like. Design/methodology/approach The paper starts by hi...

Social matching systems recommend people to people. One of the key challenges such systems face is how to build introduction mechanisms that minimize privacy concerns, while maximizing the chance of successful introductions. Another challenge is to design systems that are suitable for mobile devices. We explored the relationship between introductio...

At our School of Management, novel Internet-based tools are employed in order to enrich the in- struction of theoretical aspects of decision making with hands-on experience and expose the stu- dents to these unique tools. One example is the incorporation of online Information Markets that use the financial markets mechanism as an information aggreg...

The World Wide Web is not merely an information system; it is a social space where people interact. One central form of interaction consists of asking and answering questions. This chapter focuses on question answering sites and examines why people provide answers to others, usually to complete strangers, with very few - if any - apparent incentive...

The principal objective of this research was to understand the incentive structure in a mixed economic and social market for information. Prior research suggests that tangible incentives will crowd out intangible incentives; however, information markets invite special examination of this finding. Data representing four years of activity by 523 rese...

Prior work has demonstrated that the impact of individual information-processing limits can be observed in dynamics of mass interaction in asynchronous collaborative systems (Usenet newsgroups and email lists). Here we present the first evidence of such impacts on synchronous social interaction environments through the analysis of an Internet Relay...
