PublicationOne for All? Managing External and Internal Crowds through a Single Platform - A Case Study( 2017)
;Mrass, VolkmarWhereas crowdsourcing as a topic has often been addressed in recent literature, web-based crowdworking platforms that manage the interface between crowdsourcers and crowdworkers have not received much attention so far. Furthermore, most of these platforms focus on either the management of external or internal crowds; platforms that handle both groups are rare. This paper investigates such a provider: the German company Across Systems. It uses a hybrid model, offering an individual “mini crowdworking platform” that enables the simultaneous government of external and internal crowds as well as a more traditional marketplace crowdworking platform (crossMarket) where supply and demand meet. Using a single-case study approach, the main contribution of this paper is to shed light on a model that has the potential to change the current crowdworking platform market. We show that managing both external and internal crowds on one platform can increase the acceptance, quality and speed of task completion.Type: conference paper -
PublicationLifelong Learning and Collaboration of Smart Technical Systems in Open-Ended Environments – Opportunistic Collaborative Interactive Learning(IEEE Computer Society Press, 2016-07-19)
;Bahle, Gernot ;Calma, Adrian ;Lukowicz, Paul ;Oeste-Reiß, Sarah ;Reitmaier, Tobias ;Schmidt, Albrecht ;Sick, Bernhard ;Stumme, GerdZweig, KatharinaToday, so-called “smart” or “intelligent” systems heavily rely on machine learning techniques to adjust their behavior by means of sample data (e.g., sensor observations). But, it will be more and more complicated or even impossible to provide those data at design-time of that system. As a consequence, these systems have to learn at run-time. Moreover, these systems will have to self-organize their learning processes. They have to decide which information or knowledge source they use at which time, depending on the quality of the information or knowledge they collect, the availability of these sources, the costs of gathering the information or knowledge, etc. With this article, we propose opportunistic collaborative interactive learning (O-CIL) as a new learning principle for future, even “smarter” systems. O-CIL will enable a “lifelong” or “neverending” learning of such systems in open-ended (i.e., time-variant) environments, based on active behavior and collaboration of such systems. Not only these systems collaborate, also humans collaborate either directly or indirectly by interacting with these systems. The article characterizes O-CIL, summarizes related work, sketches research challenges, and illustrates O-CIL with some preliminary results.Type: conference paperDOI: 10.1109/ICAC.2016.36Scopus© Citations 11 -
PublicationRags to Riches - How signaling behaviour causes a power shift in crowdsourcing marketsCrowdsourcing has emerged as new form of digital work organization. This novel socio-technical ar-rangement changes the organization of work as well as its general nature. In this paper, we focus on the crowdworkers – a perspective that has been largely neglected by crowdsourcing research. We re-port results from crowdworker-interviews on two different platforms. Our research shows that quality signals of crowdworkers increase the bargaining power towards their principals, i.e. the crowdsourcers. As a result, the crowdworkers can reach a turning point of critical bargaining power at which the distribution of power shifts in their favor. We contribute to the literature by unraveling signaling behavior as mechanism influencing bargaining power and thus success in crowdsourcing. Beyond, we develop a theoretical model that indicates a shift in bargaining power over time and im-proves our understanding of crowdsourcing as novel way of organizing digital work. For practice, our results provide guidelines for crowdworkers how to improve their position in bargaining in relation to the crowdsourcer.Type: conference paper
