- KonferenzbeitragA Hybrid and Modular Framework for Mobile Campus Applications(i-com: Vol. 14, No. 1, 2015) Kiy, Alexander; Geßner, Hendrik; Lucke, Ulrike; Grünewald, FrankaMobile devices and associated applications (apps) are an indispensable part of daily life and provide access to important information anytime and anywhere. However, the availability of university-wide services in the mobile sector is still poor. If they exist they usually result from individual activities of students and teachers. Mobile applications can have an essential impact on the improvement of students’ self-organization as well as on the design and enhancement of specific learning scenarios, though. This article introduces a mobile campus app framework, which integrates central campus services and decentralized learning applications. An analysis of strengths and weaknesses of different approaches is presented to summarize and evaluate them in terms of requirements, development, maintenance and operation. The article discusses the underlying service-oriented architecture that allows transferring the campus app to other universities or institutions at reasonable cost. It concludes with a presentation of the results as well as ongoing discussions and future work
- ZeitschriftenartikelBlessing or Curse: “Everybody Knows how to Write” – How Can Good Editorial Work Be Accomplished on an Intranet?(i-com: Vol. 14, No. 1, 2015) Häfele, HeikeIn many companies, employees and managers alike are critical about the quality of their intranet. Solutions focusing on technical and process improvements frequently fail to produce sustainable results because they ignore one key factor for the quality of written content: Amid the day-to-day business routine there are too many obstacles for doing good editorial work and acquiring writing skills. To encourage the production of quality texts, an environment must be created that encourages writing, a culture where editorial work is firmly established, trained and performed efficiently.
- ZeitschriftenartikelCall for a Holistic Approach to the Use of Social Intranets(i-com: Vol. 14, No. 1, 2015) Kolb, GeorgThere are high expectations on what social intranets can do for productivity. However, there is still a large gap between promise and delivery, mainly caused by a misunderstanding of the user perspective. Usability of social intranets needs to be redefined in a holistic way, integrating the four dimensions of business, culture, technology and communication. And we need to build this integration into the workflow of social intranet teams by establishing a cross-functional body steering the project.
- ZeitschriftenartikelDeveloping Intranet Strategy: An Interdisciplinary Building Block Model(i-com: Vol. 14, No. 1, 2015) Riemke-Gurzki, ThorstenIntranets became the central platform for internal corporate communication, business processes and information technology in the last decade. This huge application scope leads to severe project traps: How can a corporate-wide, interdisciplinary intranet strategy be developed, established and maintained? This article shows the challenges and potential problems for the development of an intranet strategy. It introduces a building block model for intranet strategy. The model includes strategic dimensions as well as cultural aspects and project scope.

- KonferenzbeitragItem Familiarity as a Possible Confounding Factor in User-Centric Recommender Systems Evaluation(i-com: Vol. 14, No. 1, 2015) Jannach, Dietmar; Lerche, Lukas; Jugovac, MichaelUser studies play an important role in academic research in the field of recommender systems as they allow us to assess quality factors other than the predictive accuracy of the underlying algorithms. User satisfaction is one such factor that is often evaluated in laboratory settings and in many experimental designs one task of the participants is to assess the suitability of the system-generated recommendations. The effort required by the user to make such an assessment can, however, depend on the user’s familiarity with the presented items and directly impact on the reported user satisfaction. In this paper, we report the results of a preliminary recommender systems user study using Mechanical Turk, which indicates that item familiarity is strongly correlated with overall satisfaction.
- KonferenzbeitragMerging Interactive Information Filtering and Recommender Algorithms – Model and Concept Demonstrator(i-com: Vol. 14, No. 1, 2015) Loepp, Benedikt; Herrmanny, Katja; Ziegler, JürgenTo increase controllability and transparency in recommender systems, recent research has been putting more focus on integrating interactive techniques with recommender algorithms. In this paper, we propose a model of interactive recommending that structures the different interactions users can have with recommender systems. Furthermore, as a novel approach to interactive recommending, we describe a technique that combines faceted information filtering with different algorithmic recommender techniques. We refer to this approach as blended recommending. We also present an interactive movie recommender based on this approach and report on its user-centered design process, in particular an evaluation study in which we compared our system with a standard faceted filtering system. The results indicate a higher level of perceived user control, more detailed preference settings, and better suitability when the search goal is vague.
- ZeitschriftenartikelNo More Battles – User-centric Approaches as Key to Successful Intranets(i-com: Vol. 14, No. 1, 2015) Wagner, Anne ChristineIn the short history of intranets a lot of IT-centric paradigms have been prevailing (tool choice, architectural questions, overall IT strategy). The emergence of intranet paradigms, referred to as Web2.0, as well as changed user expectations due to consumerization and high adaption of mobile devices challenge the traditionally technology-driven approach in enterprises: Today, users realize that there is more to claim and fight for. This article introduces approaches that start from the practitioner's perspective and help to align users, IT and strategic stakeholders with the purpose of forming an alliance between them and of finding the scope and design that fits all requirements.
- ZeitschriftenartikelNo Success without Purpose(i-com: Vol. 14, No. 1, 2015) Gumm, DorinaThe purpose an organisation attaches to its intranet should be the starting point for justifying an intranet project, defining use cases and ultimately being able to measure its success. An intranet's prospects for success are best when it is perceived as a tool for operations management. This is one of the core findings of the “KlinikNet 2.0” project chosen by hospital directors as one of five “IT Key Topics” in 2014.
