Software for People: A Paradigm Change in the Software Industry
No full textThe highly competitive and globalized software market is creating pressure on software companies. Given the current boundary conditions, it is critical to continuously increase time-to-market and reduce development costs. In parallel, driven by private life experiences with mobile computing devices, the World Wide Web and software-based services, peoples’ general expectations with regards to software are growing. They expect software that is simple and joyful to use. Given these boundary conditions, software companies need to fundamentally reconsider the way they develop and deliver software to their customers. This editorial article motivates the paradigm change towards “software for people”. We first illustrate in more detail the two important categories of challenges software companies are currently faced with. Building on a short review of the historic evolution of software, we explain the major reasons that caused these challenges. Driven by the more mature automotive industry, we outline a set of key principles that may help software companies to tackle these challenges. Finally, we summarize the structure and content of the book, building on these key principles and providing a comprehensive overview on fundamentals, trends and best practices for building software for people
Software usability in small and medium sized enterprises in Germany: An empirical study
No full textUsability has become a competitive factor in the software industry. Specifically, the software industry in the United States has recognized this important factor and successfully leverages it for achieving competitive advantage. Compared to this fast development in the US, it seems questionable whether this view is also widespread among small and medium sized software producing and client companies in Germany and whether they direct sufficient attention to usability. This article presents the results of an empirical study exploring the status quo of the importance, the knowledge and the actual use of usability concepts among small and medium sized enterprises (SMEs) in Germany. Following an organizational field perspective, we investigate how interactions between actors in the software field influence the usability awareness as well as the knowledge and actual use of usability concepts. Based on the results of our study, we provide recommendations on how to increase awareness and maturity of software usability in SMEs in Germany
„Mehr als nur Programmieren“ - Eine KI-Werkstatt am KIT bildet Studierende für praktische Anwendungen von künstlicher Intelligenz aus. - Campus-Report am 21.12.2021
No full textDer Einsatz Künstlicher Intelligenz scheint keine Grenzen zu kennen. Überall entstehen riesigen Datenmengen, mit denen man sogenannte KI-Systeme trainieren kann. Dadurch werden ganz neue Dienstleistungen und Produkte möglich. Wer auf den globalen Märkten der Zukunft die Nase vorn haben will, muss mit den KI-Technologien kreativ umgehen können. Das aber erfordert mehr als nur Kenntnisse im Programmieren von Algorithmen. Im Rahmen der Bund-Länder-Initiative „Künstliche Intelligenz in der Hochschulbildung“ hat das Karlsruher Institut für Technologie jetzt gemeinsam mit den Hochschulen in Hohenheim, Bayreuth und Frankfurt den Auftrag erhalten, eine KI-Werkstatt zu entwickeln. In ihr werden Studierende der Wirtschaftswissenschaften lernen, wie man Künstliche Intelligenz in der Praxis gewinnbringend einsetzen kann
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
LadderBot: A requirements self-elicitation system
No full textLadderBot is an end-user requirements self-elicitation system using the laddering interview technique. The system is currently in a pre-final state, with most of its functionalities working. It is capable of conducting a laddering interview with end-users and visualizing the interview structure in a graphical interface.
LadderBot is configured to elicit consequences and values for three attributes. The list of attributes for the evaluation will be generated in a pre-test session, via triadic sorting. LadderBot asks the user to identify the most relevant attribute from the list. This attribute is used as seed for the ACV chain until the users switch to the next attribute, for which the selection process is repeated, excluding already chosen attributes. When asking why-questions repeatedly, the chatbot will rely on four techniques for rephrasing questions to help and guide the user. Peer-reviewed guidelines for human interviewers on how to conduct laddering interviews inspired the utilized techniques. For now, the four techniques are applied by LadderBot at random. However, no technique may be used two times in a row. The visualization of the current status of the interview on the left side updates itself for each elicited consequence before LadderBot asks the next question. To end the elicitation for a specific attribute, or the interview in general, a human interviewer would need to identify when an interviewee has reached the ‘end’ of an ACV chain. As the current iteration of LadderBot is not capable of recognizing whether a user has already described all values for a chain of consequences, the bot requires the user to indicate if they want to continue the laddering process for the current attribute, or switch to the next chain. The user can make this indication using the command ‘stop’. After eliciting three ACV chains, LadderBot ends the interview.</p
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
