Item type:Publication, A design model for knowledge-based pricing services in the retail industryMarketing research has identified several benefits of dynamic pricing strategies in the retail industry. However, today's retailers are limited to apply them in real-time to customer needs as corresponding pricing services provided by smart product infrastructures have not been adopted so far. In addition, dynamic pricing strategies rely on a business service ecosystem of retailers, suppliers, customers and regulatory bodies and thus, interoperability is required. Because unprecedented, our objectives are therefore to propose, implement and evaluate a design model for pricing services that rely on explicit semantics and rules, denoted as knowledge-based pricing services (KPSs). In this work, we propose a design model for KPSs and empirically evaluate their utility from a customer perspective with the help of a web-based application. We finally draw implications for business models in the retail industry and discuss tools that already exist to adopt KPSs in the near future.Type:journal articleJournal:International Journal of Web Engineering and TechnologyVolume:6Issue:4Scopus© Citations 3 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The Role of Product Reviews on Mobile Devices for In-store Purchases: Consumers' Usage Intentions, Costs and Store PreferencesProduct reviews help consumers in purchase decisions. In contrast to reviews obtained from websites on the desktop, it is open if they are adopted for in-store purchases on mobile devices. Further, it is open to which degree free product reviews provided by users or paid product reviews provided by experts are adopted and influence consumers' preferences for stores that offer access to them. To address these questions, a theoretical model based on Innovation Diffusion Theory, Technology Acceptance Model and Theory of Planned Behaviour is developed and empirically tested with 116 subjects. Results indicate that consumers intend to use product reviews on mobile devices for in-store purchases. Moreover, they are willing to pay almost five percent of the product's price for a review. Based on these findings, new business models for providers of product reviews and store managers are feasible, which extend physical products with value-added online servicesType:journal articleJournal:International Journal of Internet Marketing and Advertising: Special Issue on Information Systems and MarketingVolume:6Issue:3Scopus© Citations 22 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Towards Empirically Validated Ubiquitous Information Systems : Results from a Pretest and Three Empirical StudiesResearch on ubiquitous information systems (UIS) has recently gained attention in the IS community. But dedicated empirical instruments that are robust and capture individual characteristics of UIS are still missing. A rather new empirical construct derived from Task-Technology Fit theory was proposed and denoted as Situation-Service Fit (SSF). This paper shows how SSF can be used within the Situational Design Method for IS, a design method tailored to UIS. For this purpose, the SSF instrument is first tested for face validity as well as discriminant and convergent validity. Then, SSF is evaluated as a predictor variable of behavioral intentions to use services that are embedded in UIS. Hereby, also discriminant validity of SSF with regard to perceived usefulness and perceived ease of use is assessed. For this purpose, data from a four-year EU project is used, which includes a pretest and three empirical user studies. Results show that SSF can be a significant predictor of service usage. However, validity issues still exist and thus, further research on the SSF instrument is recommended.Type:conference paperVolume:online - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Effects of External Conceptual Models and Verbal Explanations On Shared Understanding in Small GroupsEffective conceptual modeling requires a shared understanding of the concepts that are found in an application domain. Achieving such understanding, especially for large design problems, is a challenging, and long-standing problem. Conceptual models tend to be either subjective representations of individuals that require mutual knowledge sharing between members of a modeling team or externalized normative representations that require knowledge transfer from model preceptors to model receptors. Model preceptors have either created a conceptual model or conceived it by another preceptor. In prior studies, normative conceptual models were used to investigate knowledge transfer between preceptors and receptors. This research, in contrast, investigates knowledge transfer of conceptual models between model owners and receptors. A 2x2 study design with modeling novices was used that varied the type of conceptual modeling language and the type of information system. Further testing investigated whether knowledge transfers were affected by additional verbal explanations given by the preceptor. Each modeler was provided access to two conceptual modeling languages that naturally support structure or process representations. The study investigated whether the use of particular conceptual modeling languages differ in their effects on shared understanding between two persons and whether additional verbal explanations might increase shared understanding. The results of this exploratory empirical study provide useful insights into the use of Conceptual Modeling Language pairs for shared understanding in conceptual modeling in small groupsType:conference paperJournal:Lecture Notes in Computer Science (LNCS)Volume:Volume 6998Scopus© Citations 6 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Linkage of Heterogeneous Knowledge Resources within In-store Dialogue InteractionDialogue interaction between customers and products improves presentation of relevant product information in in-store shopping situations. Thus, information needs of customers can be addressed more intuitive. In this article, we describe how access to product information can be improved based on dynamic linkage of heterogeneous knowledge representations. We therefore introduce a conceptual model of dialogue interaction based on multiple knowledge resources for in-store shopping situations and empirically validate its utility with end-usersType:conference paperVolume:LNCS 6497Scopus© Citations 3 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, IKS Deliverable - D8.9: Interactive Knowledge Impact Report According to EU Impact Assessment GuidelinesPublic EU Deliverable of the IKS project - This report provides an evaluation of the impact that IKS and its related projects had on the CMS community. Impact metrics have been selected from online analytics tools (i.e. website visits, unique visitors, page views, page views per visit, average visit duration, bounce rate and percentage of new visits) as well as EU assessment guidelines, feedback from the third EU review meeting and Information Systems research (i.e. technology impact, business impact, research impact, educational impact, impact on CMS community, sustainability of project results and on going activities beyond 2012, benefits of semantic-enhanced CMS). Data used for this impact evaluation was taken from online access to websites relevant to IKS and the IKS Impact Assessment Survey 2012 conducted at the end of 2012. Results indicate that IKS and its related projects have generated almost 360 000 page views over the course of the last six months in 2012. This together with the graduation of Apache Stanbol from its incubator status in 2012 can be interpreted as a remarkable impact of the project. Moreover, results of the IKS Impact Assessment Survey 2012 indicate that the combination of semantic technologies and CMS are able to provide several benefits such that semantic-enhanced CMS are recommended to a high degree. Additionally, technological impact, business impact and educational impact of IKS results are rated at a notable degree, too. All in all, it can be therefore concluded that IKS was a successful EU project.Type:work report - Some of the metrics are blocked by yourconsent settings
Item type:Publication, IKS Deliverable - D6.4: End User Perception of Semantic CMS ApplicationsPublic EU Deliverable of the IKS project - This deliverable develops and tests a user-oriented content-support acceptance model (CSAM) which helps to better understand the phenomena of content service adoption. Additional, it provides recommendations on how to improve existing IKS-related content services. In this regard, a literature review on adoption constructs is conducted from which then CSAM is developed. The major advantage of CSAM is its flexibility to incorporate various empirical constructs and dimensions such as content service characteristics (e.g. interactivity, relevancy, perceived ease of use), service utility (e.g. perceived usefulness) or service utilization (e.g. likeliness of reuse) that can be particularly applied to the evaluation of concrete CMS applications. This flexibility will be shown in this report by applying CSAM to a traditional CMS application in a business situation (i.e. the IKS Tourism use case) as well as to a ubiquitous CMS application in a private situation (i.e. the IKS AmI use case). Results show, that CSAM is supported by the empirical data and that informed decision can be derived for a revision of existing IKS-related content services.Type:work report - Some of the metrics are blocked by yourconsent settings
Item type:Publication, IoT-I Deliverable - D2.4: Social Acceptance and Impact EvaluationInternet of Things (IOT) services - namely sensor-based IS services facilitated by identification technologies such as barcode, radio frequency, IPv6, or global satellite communication - provide new security and privacy challenges in private and business situations of our everyday life. Accordingly, the relevance of privacy and security has been addressed in prior Information Systems research and, as a result, design methodologies, guidelines and policies have been discussed and proposed. However, there still exists no robust empirical instrument that has been developed and successfully tested for the class of IOT services and that combines critical privacy factors and IT acceptance research. Thus, privacy factors need to be identified that have an impact on the behavioural intention to use IOT services, individuals' willingness to pay for these services and their willingness to provide personal information in business situations and private situations. The contribution of this report is therefore to address this lack of knowledge in order to provide policy makers, IT developers and IS researchers with recommendations on how to design IOT services. The proposed underlying research model is based on utility maximization theory and integrates theoretical constructs from the Extended Privacy Calculus Model and the Technology Acceptance Model. This model is empirically tested with 92 IT-savvy subjects via an online survey. Results indicate that behavioural intentions to use IOT services are influenced by various contradicting success factors such as perceived privacy risks and personal interests. That is, the driver of adoption results from the trade-off between these factors. Additionally, success factors depend on the underlying usage situation be it a business situation or a private situation. It can be further stated that contextual factors such as legislation and data security as well as transparency of information use influence the adoption of IOT services. Accordingly, further research must focus on a better understanding of these success factors to increase the adoption of both useful and secure IOT services in the future.Type:work report - Some of the metrics are blocked by yourconsent settings
