Over the last few decades, however, researchers and practitioners alike have, following the advances in natural language understanding, started recognizing the benefits of integrating soft information into financial modelling. In line with the above, this paper examines whether contemporary attention-based sequence-to-sequence models, known as Transformers, can help improve stock return volatility prediction when applied to corporate annual reports. Using a publicly available benchmark dataset, we show, in an empirical analysis, that out-of-the-box Transformer models have the ability to outmatch current state-of-the-art results and, more importantly, that our proposed feature-based Transformer approach can outperform a robust numerical baseline. To the best of our knowledge, this is the first empirical study focusing on stock return volatility prediction (1) to ever experiment with state-of-the-art Transformer architectures and (2) to demonstrate that a model based solely on soft information can surpass its numerical counterpart. Furthermore, we show that by including an additional numerical feature into our best text-only model, we can push the performance of our model even further, suggesting that soft and hard information contain different predictive signals."}],"status":"public","publication":"2020 IEEE International Conference on Big Data (Big Data)","type":"conference","language":[{"iso":"eng"}],"_id":"21563","department":[{"_id":"196"}],"user_id":"60721"},{"extern":"1","language":[{"iso":"eng"}],"_id":"17096","department":[{"_id":"196"}],"user_id":"72849","abstract":[{"text":"Augmented Reality (AR) technologies have evolved rapidly over the last years, particularly with regard to user interfaces, input devices, and cameras used in mobile devices for object and gesture recognition.

Against this background, in this case study, we explain how hospitals can successfully implement organization-wide process orientation. To do so, we conducted an exploratory single case study with semi-structured, face-to-face interviews and document analyses as our primary data-collection methods. We developed a theoretical framework of antecedents, interventions, enablers, barriers, and consequences that explain the trajectory of this successful hospital-reorganization project. We contribute a substantive theory on which other researchers can build and can extend in future studies. Further, in analyzing our unique case, we identify factors that the extant literature has not yet discussed, such as the blackboxing of diagnosis and treatment activities as an enabler. In line with existing literature, we also found that, even in this case, inflexible healthcare IT represented a barrier that hindered the case study in implementing process orientation.","lang":"eng"}],"publication":"Journal of Information Technology Theory and Application","type":"journal_article","main_file_link":[{"url":"https://aisel.aisnet.org/jitta/vol19/iss4/3/"}],"title":"Hospital-wide Process-oriented Organization of Care: The Case of Turku University Central Hospital","volume":19,"date_created":"2020-06-17T09:30:22Z","author":[{"full_name":"Suomi, Reima","last_name":"Suomi","first_name":"Reima"},{"last_name":"Müller","id":"72849","full_name":"Müller, Oliver","first_name":"Oliver"},{"first_name":"Jan","last_name":"vom Brocke","full_name":"vom Brocke, Jan"}],"date_updated":"2022-08-17T07:21:21Z","page":"3","intvolume":"        19","citation":{"short":"R.

The majority of technology vendors now have IMC technologies in their portfolio, and the interest of companies in adopting such solutions in order to benefit from big data is increasing. Although there is first research on the business value of IMC in the form of case studies, there is a lack of large-scale quantitative evidence on the positive effect of such solutions on firm performance.

We perform an automated content analysis to identify cultural factors that employees em-phasize in their reviews. Through a regression analysis on numerical employee satisfaction ratings, we find that a culture of learning and performance orientation contributes to employee motivation, while a culture of assertiveness and gender inegalitarianism has a strong negative influence on em-ployees’ satisfaction in the IT workforce.

Traditionally, to analyze natural language, one has used qualitative data-analysis approaches, such as manual coding. Yet, the size of text data sets obtained from the Internet makes manual analysis virtually impossible. In this tutorial, we discuss the challenges encountered when applying automated text-mining techniques in information systems research. In particular, we showcase how to use probabilistic topic modeling via Latent Dirichlet allocation, an unsupervised text-mining technique, with a LASSO multinomial logistic regression to explain user satisfaction with an IT artifact by automatically analyzing more than 12,000 online customer reviews. For fellow information systems researchers, this tutorial provides guidance for conducting text-mining studies on their own and for evaluating the quality of others."}],"status":"public","type":"journal_article","publication":"Communications of the Association for Information Systems"},{"author":[{"last_name":"Gorbacheva","full_name":"Gorbacheva, Elena","first_name":"Elena"},{"last_name":"Stein","full_name":"Stein, Armin","first_name":"Armin"},{"full_name":"Schmiedel, Theresa","last_name":"Schmiedel","first_name":"Theresa"},{"first_name":"Oliver","last_name":"Müller","id":"72849","full_name":"Müller, Oliver"}],"date_created":"2020-06-22T08:14:06Z","date_updated":"2022-01-06T06:53:05Z","doi":"10.18151/7217329","title":"A gender perspective on business process management competences offered on professional online social networks","publication_identifier":{"isbn":["978-3-00-050284-2"]},"citation":{"ieee":"E.

Core business activities are being carried out through OLTP systems that provide limited monitoring capabilities of the running process instances. The article shows how to turn the gap between the classic transactional system and the process-centric approach into an organization that provides more accurate and faster decisions on the strategic and operational management levels. This study aims at determination of what kind of information can be retrieved during the process execution and it tries to identify the need for the real-time process intelligence on the example of the order-to-cash process. Furthermore, we compare two architectural approaches of the real-time process intelligence monitoring system. The proposed frameworks retrieve process data from the ERP system in order to record crucial performance indicators on a real-time basis with the use of the in-memory technology."}],"department":[{"_id":"196"}],"user_id":"72849","_id":"17106","language":[{"iso":"eng"}],"extern":"1"},{"doi":"10.1108/bpmj-02-2014-0012","title":"Interview with Michael Rosemann on ambidextrous business process management","date_created":"2020-06-22T08:24:21Z","author":[{"first_name":"Thomas","last_name":"Kohlborn","full_name":"Kohlborn, Thomas"},{"first_name":"Oliver","full_name":"Müller, Oliver","id":"72849","last_name":"Müller"},{"full_name":"Poeppelbuss, Jens","last_name":"Poeppelbuss","first_name":"Jens"},{"first_name":"Maximilian","full_name":"Roeglinger, Maximilian","last_name":"Roeglinger"}],"date_updated":"2022-01-06T06:53:05Z","publisher":"Emerald Group Publishing Limited","page":"634-638","citation":{"ama":"Kohlborn T, Müller O, Poeppelbuss J, Roeglinger M.

With the steady growth of the number of apps in the repositories the providers will inevitably face the need to fine-grain the existing hierarchy of categories used to organize the apps. In this paper we present a method to bootstrap the categorization process via topic modeling. We apply Latent Dirichlet Allocation (LDA) to the textual descriptions of iTunes apps in order to identify recurrent topics in the collection. We evaluate and discuss the results obtained from training the model on a set of almost 600,000 English-language app descriptions. Our results demonstrate that automated categorization via LDA-based topic modeling is a promising approach, that can help to structure, analyze and manage the content of app repositories. The topics produced complement the original iTunes categories, concretize and extend them by providing insights into the underlying category content.","lang":"eng"}],"publication":"International Conference on Information Systems","type":"conference","extern":"1","language":[{"iso":"eng"}],"department":[{"_id":"196"}],"user_id":"72849","_id":"17111"},{"doi":"10.2139/ssrn.2195435","title":"Open Societal Innovation: The Alemannic Definition","author":[{"last_name":"von Lucke","full_name":"von Lucke, Jörn","first_name":"Jörn"},{"full_name":"Herzberg, Johann","last_name":"Herzberg","first_name":"Johann"},{"full_name":"Kluge, Ulrike","last_name":"Kluge","first_name":"Ulrike"},{"first_name":"Jan","last_name":"vom Brocke","full_name":"vom Brocke, Jan"},{"last_name":"Müller","id":"72849","full_name":"Müller, Oliver","first_name":"Oliver"},{"full_name":"Zimmermann, Hans-Dieter","last_name":"Zimmermann","first_name":"Hans-Dieter"}],"date_created":"2020-06-23T08:07:29Z","date_updated":"2022-01-06T06:53:05Z","citation":{"apa":"von Lucke, J., Herzberg, J., Kluge, U., vom Brocke, J., Müller, O., &#38; Zimmermann, H.-D.
