Anforderungsvalidierung unter Nutzung echtzeit simulierter virtueller Prototypen zur Verbesserung der Produktqualität
(FAU University Press, 2017)
Im Rahmen der Anforderungsermittlung werden verschiedene Methoden, wie Befragungs‐ und Beobachtungstechniken eingesetzt, um die bewussten Kundenanforderungen zu erfassen. Verborgene (unbewusste) Kundenanforderungen werden dabei meist nicht berücksichtigt. Aus erhobenen Kundenanforderungen lassen sich z.B. mit einer QFD die späteren Produktmerkmale ableiten. Aufgrund der unscharfen Kundenanforderungslage kommt es bei dem entwickelten Produkt oft zu einer Abweichung von den vom Kunden gewünschten Eigenschaften. Jede ...

Structured Eyetracking-based Requirements Validation with the Help of Virtual Prototypes
(INEGI/Faculdade de Engenharia Universidade do Porto, 2017)
Customer requirements form the basis of every product development project. Incomplete requirements and lack of involvement of customers are the main factors for the failure of a product at the buyer's market (Hull et al. 2011). The Quality Function Deployment (QFD) describes a common method for translating customer requirements into product features. For this purpose, the QFD provides various matrices for the prioritization and quantification of the requirements, through the various phases of the product development. ...

Classifying Smart Personal Assistants: An Empirical Cluster Analysis
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2019)
The digital age has yielded systems that increasingly reduce the complexity of our everyday lives. As such, smart personal assistants such as Amazon’s Alexa or Apple’s Siri combine the comfort of intuitive natural language interaction with the utility of personalized and situation-dependent information and service provision. However, research on SPAs is becoming increasingly complex and opaque. To reduce complexity, this paper introduces a classification system for SPAs. Based on a systematic literature review, a ...

Not All Reviews are Equal - a Literature Review on Online Review Helpfulness
(Association for Information Systems, 2019)
The amount of online reviews is growing significantly. Between 2014 and 2017, the number of reviews for TripAdvisor grew by 300% and for Yelp by 208%. However, not all online reviews are equally valuable. Some reviews are perceived to be more helpful or trustworthy then others. Hence, plethora of scholars have investigated the role of online reviews and researched factors and characteristics determining its helpfulness. Nevertheless, mixed findings were found. Consequently, the purpose of our paper is to present a ...

Towards A Taxonomy of Text Mining Features
(Association for Information Systems, 2019)
Recently, text mining has received special attention from both researchers and practitioners, since it enables the development of intelligent and automated services. Text mining has been influenced by different disciplines like computer science, statistics, computational linguistics and library and information sciences. However, text mining features that evolved in one particular discipline are often unknown or rarely used in the other disciplines. No scientific feature framework exits which facilitates costly feature ...

Gestaltung smarter persönlicher Assistenten zwischen Rechtsverträglichkeit und Dienstleistungsqualität
(Gesellschaft für Informatik e.V. (GI), 2019)
Smarte persönliche Assistenten von Amazon, Google und zahlreichen anderen Anbietern ermöglichen es, qualitativ hochwertige elektronische Dienstleistungen anzubieten. Gleichzeitig bringen diese Systeme auch viele Risiken mit sich. Berichte von diskriminierenden oder unverständlichem Systemverhalten häufen sich und verursachen Skepsis in der Gesellschaft. Diesen Problemen kann mit einer gleichermaßen rechtsverträglichen und qualitätsorientierten ITGestaltung entgegengewirkt werden. In diesem Beitrag werden Rechtsvert ...

Alexa, Can You Help Me Solve That Problem? - Understanding the Value of Smart Personal Assistants as Tutors for Complex Problem Tasks
(universi - Universitätsverlag Siegen, 2019)
In recent decades, the number of students per lecturer at universities has constantly risen. In these learning scenarios, individual lecturer support for helping students actively acquiring new knowledge is hardly possible. However, active student behavior is necessary for successful learning. Smart Personal Assistants such as Amazon’s Alexa or Google’s Home promise to fill this gap by being students’ individual tutors. In order to understand what students expect from Smart Personal Assistants as tutors and how they ...

Assessment of the changeability of plastics processing systems
(Society of Plastics Engineers, 2014)
Changeable production systems are still being developed, especially in the field of plastics processing. Here, the assessment of the changeability is a decisive factor. This investigation deals with the assessment of the changeability of a modular pilot plant, and derives approaches for the further development of an evaluation system, as well as potential means to increase the changeability.
