We call such marketplaces IT service markets. IT service markets have some core architectural building blocks that impact the quality attributes of these markets. However, these building blocks and their impacts are not well-known. Thus, design choices for IT service markets have been made ad-hoc until now. Furthermore, only single aspects of such markets have been investigated until now, but a comprehensive view is missing.In this paper, we identify common features and their interrelations on the basis of a systematic literature review of 60 publications using grounded theory.This knowledge provides an empirical evidence on the interdisciplinary design choices of IT service markets and it serves as a basis to support market providers and developers to integrate market features. Thereby, we make a first step towards the creation of a reference model for IT service markets that provides a holistic integrated view that can be used to create and maintain successful markets in the future.}}, author = {{Jazayeri, Bahar and Platenius, Marie and Engels, Gregor and Kundisch, Dennis}}, booktitle = {{Proceedings of the 14th International Conference on Service Oriented Computing (ICSOC)}}, pages = {{301--316}}, publisher = {{Springer}}, title = {{{Features of IT Service Markets: A Systematic Literature Review}}}, doi = {{10.1007/978-3-319-46295-0_19}}, volume = {{9936}}, year = {{2016}}, } @article{2467, author = {{Bach, Christoph and Kundisch, Dennis and Neumann, Jürgen and Schlangenotto, Darius and Whittaker, Michael}}, journal = {{HMD Praxis der Wirtschaftsinformatik}}, number = {{4}}, pages = {{486--498}}, title = {{{Dokumentenorientierte NoSQL-Datenbanken in skalierbaren Webanwendungen - Eine Analyse am Beispiel von MongoDB und der Webanwendung PINGO}}}, volume = {{53}}, year = {{2016}}, } @inproceedings{3283, author = {{Bräuer, sebastian and Monhof, Markus and Klör, Benjamin and Beverungen, Daniel}}, booktitle = {{Proceedings of the IEEE Conference on Business Informatics (CBI 2016)}}, location = {{Paris, France}}, title = {{{Residential Energy Storage from Repurposed Electric Vehicle Batteries — Market Overview and Development of a Service-Centered Business Model}}}, year = {{2016}}, } @inproceedings{2699, author = {{Görzen, Thomas and Kundisch, Dennis}}, booktitle = {{Proceedings of the 22nd Americas' Conference on Information Systems (AMCIS)}}, location = {{San Diego, USA}}, title = {{{Can the Crowd Substitute Experts in Evaluation of Creative Ideas?

We use data from a popular German Question & Answer community where goals are represented in the form of badges.

After this certain badge, the difficulty level sud-denly drops and remains constant throughout up to the last badge in the hierarchy.

(1999) propose a prospect theory model for goal behavior. Their analytical model is based on the assumption that goals inherit the main properties of the prospect theory value function, i.e., reference point dependence, loss aversion, and diminishing sensitivity. We investigate whether these main properties transfer to goal behavior in the field. We take user activity data from a gamified Question & Answer community and analyze how users adjust their contribution behavior in the days surrounding goal achievement, where goals are represented by badges. We find that users gradually increase their performance in the days prior to earning a badge, with performance peaking on the day of the promotion. In subsequent days, user performance gradually diminishes again, with the decline being strongest on the day immediately following the badge achievement. These findings reflect the characteristic S-shape of the prospect theory value function which is convex below the reference point and concave above it. Employing the target-based approach, we can interpret the value function as a cumulative density function of a unimodal probability distribution. Our results suggest that it is more likely that active members of the community focus on the next badge relative to the status already achieved, as their next goal and are less likely to focus on more remote (higher-ranked) badges. Our results thus support the transferability of the main properties of the prospect theory value function to goal behavior in the field and suggest a distinct shape of the value function around goals.}}, author = {{von Rechenberg, Tobias and Gutt, Dominik and Kundisch, Dennis}}, journal = {{Decision Analysis}}, number = {{2}}, pages = {{153----171}}, publisher = {{INFORMS}}, title = {{{Goals as Reference Points: Empirical Evidence from a Virtual Reward System}}}, doi = {{10.1287/deca.2016.0331}}, year = {{2016}}, } @inproceedings{205, author = {{Herrmann, Philipp and Gutt, Dominik and Rahman, Mohammad}}, booktitle = {{INFORMS Annual Meeting}}, location = {{Nashville, USA}}, title = {{{Crowd-Driven Competitive Intelligence: Understanding the Relationship between Local Market Structure and Online Rating Distributions}}}, year = {{2016}}, } @inproceedings{206, author = {{Herrmann, Philipp and Gutt, Dominik and Rahman, Mohammad}}, booktitle = {{NBER Summer Institute on the Economics of Information Technology and Digitization}}, location = {{Cambridge, MA, USA}}, title = {{{Crowd-Driven Competitive Intelligence: Understanding the Relationship between Local Market Structure and Online Rating Distributions}}}, year = {{2016}}, } @inproceedings{180, abstract = {{Recent literature reports concerns about implausibly high Overall ratings in the sharing economy, which undermines the credibility of this rating as a quality signal. This study empirically investigates the relationship between quality and price, commonly captured by the Value dimension in multidimensional rating systems, to reveal whether reviewers form a perception of quality that they then express in the Value dimension, rather than in the Overall rating. We test our hypotheses on a comprehensive panel dataset for 14,859 Airbnb listings in New York. Our preliminary empirical findings show that an increase in price leads to a significant and substantial decrease in the Value rating, suggesting that Value ratings can offer a valuable source of information for potential buyers in addition to the supposedly inflated Overall rating. Moreover, this mechanism has substantial implications for potential buyers who seek to evaluate a listing’s quality and for a seller’s price setting. }}, author = {{Gutt, Dominik and Kundisch, Dennis}}, booktitle = {{Proceedings of the 37th International Conference on Information Systems (ICIS), Dublin, Ireland}}, location = {{Dublin, Ireland}}, title = {{{Money Talks (Even) in the Sharing Economy: Empirical Evidence for Price Effects in Online Ratings as Quality Signals}}}, year = {{2016}}, } @article{5676, author = {{Rauchecker, Gerhard and Schryen, Guido}}, journal = {{Im Einsatz}}, pages = {{44--46}}, publisher = {{Stumpf & Kossendey}}, title = {{{Projekt KUBAS: Koordination ungebundener Vor-Ort-Helfer}}}, volume = {{23}}, year = {{2016}}, } @inproceedings{4374, author = {{Zimmermann, Steffen and Herrmann, Philipp and Kundisch, Dennis and Nault, Barrie}}, booktitle = {{Workshop on IS Design and Economic Behavior (ISDEB)}}, location = {{Ilmenau, Germany}}, title = {{{How do different Sources of the Variance of Online Consumer Ratings matter?}}}, year = {{2016}}, } @inproceedings{5595, author = {{Wagner, Gerit and Prester, Julian and Roche, Maria and Benlian, Alexander and Schryen, Guido}}, booktitle = {{International Conference on Information Systems}}, title = {{{Factors Affecting the Scientific Impact of Literature Reviews: A Scientometric Study}}}, year = {{2016}}, } @article{5617, abstract = {{CAPTCHAs are challenge-response tests that aim at preventing unwanted machines, including bots, from accessing web services while providing easy access for humans. Recent advances in artificial-intelligence based attacks show that the level of security provided by many state-of-the-art text-based CAPTCHAs is declining. At the same time, techniques for distorting and obscuring the text, which are used to maintain the level of security, make text-based CAPTCHAs diffcult to solve for humans, and thereby further degrade usability. The need for developing alternative types of CAPTCHAs which improve both, the current security and usability levels, has been emphasized by several researchers.

When generating such ideas, humans make use of two properties of the human cognitive system: First, their ability to build up knowledge (i.e., raw material for new ideas), and second, their ability to flexibly recombine that knowledge. While these properties enable humans to generate innovative ideas, the amounts of knowledge and cognitive flexibility that humans can possess are limited, which in turn limits human idea generation capability. With business model idea generators, a new class of information systems is proposed that can contribute to alleviating the limits that constrain human idea generation. The ideas that such idea generators produce can complement human business model ideas, thereby increase the probability for high-quality ideas, and eventually raise the odds of successful business model innovation.
