Users are asked to evaluate the quality of the composed product after purchase. The quality of the basic service influences the performance of the composed services but cannot be observed directly. The question we pose is whether it is possible to use user evaluations on composed services to assess the quality of basic services. We discuss how to combine aggregation of evaluations across users and disaggregation of information on composed services to derive valuations for the single components. As a solution we propose to use the (weighted) average as aggregation device in connection with the Shapley value as disaggregation method, since this combination fulfills natural requirements in our context. In addition, we address some occurring computational issues: We give an approximate solution concept using only a limited number of evaluations which guarantees nearly optimal results with reduced running time. Lastly, we show that a slightly modified Shapley value and the weighted average are still applicable if the evaluation profiles are incomplete.}}, author = {{Feldotto, Matthias and Haake, Claus-Jochen and Skopalik, Alexander and Stroh-Maraun, Nadja}}, booktitle = {{Proceedings of the 13th Workshop on Economics of Networks, Systems and Computation (NetEcon 2018)}}, isbn = {{978-1-4503-5916-0}}, location = {{Irvine, California, USA}}, pages = {{5:1--5:6}}, title = {{{Disaggregating User Evaluations Using the Shapley Value}}}, doi = {{10.1145/3230654.3230659}}, year = {{2018}}, } @inproceedings{2832, author = {{Schlangenotto, Darius and Kundisch, Dennis and Poniatowski, Martin}}, booktitle = {{Proceedings of the 24th Americas Conference on Information Systems (AMCIS)}}, location = {{New Orleans, USA}}, title = {{{What Drives Paid Search Success: A Systematic Literature Review}}}, year = {{2018}}, } @inproceedings{2861, abstract = {{The Digital Transformation alters business models in all fields of application, but not all industries transform at the same speed. While recent innovations in smart products, big data, and machine learn-ing have profoundly transformed business models in the high-tech sector, less digitalized industries—like agriculture—have only begun to capitalize on these technologies. Inspired by predictive mainte-nance strategies for industrial equipment, the purpose of this paper is to design, implement, and evaluate a predictive maintenance method for agricultural machines that predicts future defects of a machine’s components, based on a data-driven analysis of service records. An evaluation with 3,407 real-world service records proves that the method predicts damaged parts with a mean accuracy of 86.34%. The artifact is an exaptation of previous design knowledge from high-tech industries to agriculture—a sector in which machines move through rough territory and adverse weather conditions, are utilized exten-sively for short periods, and do not provide sensor data to service providers. Deployed on a platform, the prediction method enables co-creating a predictive maintenance service that helps farmers to avoid resources shortages during harvest seasons, while service providers can plan and conduct maintenance service preemptively and with increased efficiency. }}, author = {{Lüttenberg, Hedda and Bartelheimer, Christian and Beverungen, Daniel}}, location = {{Portsmouth, UK}}, title = {{{Designing Predictive Maintenance for Agricultural Machines}}}, year = {{2018}}, } @inproceedings{2564, author = {{Gutt, Dominik}}, booktitle = {{Proceedings of the 25th European Conference on Information Systems (ECIS)}}, location = {{Portsmouth, UK}}, title = {{{In the Eye of the Beholder? – Empirically Decomposing Different Economic Implications of the Online Rating Variance}}}, year = {{2018}}, } @techreport{2565, abstract = {{This note deals with agreeability in nontransferable utility (NTU) differential games.
