- ZeitschriftenartikelDesign and implementation of a platform for the citizen science project migraine radar(it - Information Technology: Vol. 60, No. 1, 2018) Wogenstein, Florian; Gaul, Charly; Kropp, Peter; Scheidt, Jörg; Siebenhaar, Yannic; Drescher, JohannesIn this paper we introduce the design and technical implementation of the citizen science project Migraine Radar. The goal of the project is to establish a large collection of migraine attack data in order to explore the trigger factors of migraine attacks. A main focus is the investigation of the influence of environmental factors like weather or changes in the geomagnetic activity on the frequency of migraine attacks. After registering with the project, participants report their migraine attack data using a web app or one of the smartphone apps implemented for Android and iOS. As a benefit, the system serves as a personal headache calendar and participants have access to statistics and individualized reports about their attacks. For scientific analysis the data are pre-processed and provided to the researchers in an anonymized way.
- ZeitschriftenartikelSoftware Requirements Selection with Incomplete Linguistic Preference Relations(Business & Information Systems Engineering: Vol. 63, No. 6, 2021) Sadiq, Mohd.; Parveen, Azra; Jain, S. K.Software requirements (SRs) selection is a multicriteria group decision making (MCGDM) problem whose objective is to select the SRs from the pool of the requirements on the basis of different criteria. In MCGDM, different decision makers have different opinions of the same requirement so it is difficult to decide which set of SRs to implement during the different releases of the software. During the MCGDM process, decision makers may use linguistic variables to specify preferences of requirements over other requirements. In real life applications, it has been observed that sometimes decision makers cannot evaluate the SRs due to their lack of knowledge and limited expertise related to the problem domain. In this situation, incomplete linguistic preference relations (LPRs) are constructed. In literature, SRs selection with incomplete LPRs is still an unresearched problem. Therefore, to address this issue, a method is presented for the selection of SRs with incomplete LPRs. Finally, the applicability of the proposed method is explained with the help of an example.
- ZeitschriftenartikelSoziale Wissensumgebungen(Wirtschaftsinformatik: Vol. 56, No. 2, 2014) Pawlowski, Jan M.; Bick, Markus; Peinl, René; Thalmann, Stefan; Maier, Ronald; Hetmank, Lars; Kruse, Paul; Martensen, Malte; Pirkkalainen, HenriWissensmanagement stellt ein Schlüsselelement sowohl für Wissenschaftler als auch für Praktiker in der Wirtschaftsinformatik dar. Das gilt auch für jene, die von den bisher erzielten Resultaten, die den übertriebenen Versprechungen und idealisierten Visionen nicht gerecht werden konnten, desillusioniert sind. Social Software hat als globale Erfolgsgeschichte ähnliche Erwartungen geweckt in Bezug auf die Art und Weise, wie Unternehmen mit ihrem Wissen besser umgehen können. Können diese Erwartungen jedoch in der wissenschaftlichen Forschung und in der Praxis erfüllt werden? Der Artikel versucht, aktuelle Forschungstrends und -lücken aufzuzeigen und legt hierbei einen Schwerpunkt auf soziale Wissensumgebungen. Das vorgeschlagene Forschungsprogramm weist vier Schwerpunkte auf: Die semi-permeable Organisation, Social Software in professionellen Arbeitsumgebungen, Wissen der Crowd und grenzüberschreitendes Wissensmanagement. Um diese Herausforderungen zu adressieren werden drei methodische Lösungen identifiziert: designorientierte Lösungen, analytische Lösungen und interdisziplinärer Dialog.AbstractKnowledge management represents a key issue for both information systems’ academics and practitioners, including those who have become disillusioned by actual results that fail to deliver on exaggerated promises and idealistic visions. Social software, a tremendous global success story, has prompted similarly high expectations regarding the ways in which organizations can improve their knowledge handling. But can these expectations be met, whether in academic research or the real world? The article seeks to identify current research trends and gaps, with a focus on social knowledge environments. The proposed research agenda features four focal challenges: semi-permeable organizations, social software in professional work settings, crowd knowledge, and cross-border knowledge management. Three solutions emerge as likely methods to address these challenges: design-oriented solutions, analytical solutions, and interdisciplinary dialogue.
