Computer-Aided Requirements Engineering Software, for doing Requirement Engineering with Business Processes
AGP

Role: Main Applicant

Financement: HES-SO Rectorat

Description du projet : Swiss administrations that want to acquire new IT services have to follow a strictly regulated public procurement procedure ('procédure d'appel d'offres'). To do so, they first need to gather their IT requirements in a process known as Requirements Engineering. Then, those requirements must be published. Based on this publication, IT vendors can propose their bid. Finally, the administration chooses the best bid and mandates the IT vendor for implementing the wanted service. The legal framework for public procurements is specified by very restrictive international agreements (GATT ' WTO). However nothing is available up to now in order to help Swiss administrations do their requirements engineering towards public procurement of IT services. On the other hand, Swiss administrations are at ease with Business Process Management and BPMN, which are enforced by the Swiss eGovernment strategy. The project presented here aims at offering a concrete aid for Swiss administrations in the form of an online platform called CARES (Computer-Aided Requirements Engineering Software). This platform would help them do their requirements engineering, leveraging standards and best practices of BPM defined in the Swiss E-Government strategy, thus facilitating the public procurement process for IT services in Switzerland. The main objectives of the project are: 1. Define a modeling language suited for requirements engineering in the context described (e.g. BPMN possibly extended) 2. Create a practical methodology of requirements engineering towards the public procurement for IT services 3. Set up an online platform allowing Swiss administrations to create WTO-conform procurement for IT-services (platform will include the methodology above and relevant modeling tools). As issuing WTO-conform procurements does not only apply to public administrations, but is also useful for private companies, the platform will be generic enough to be re-used outside the strict context of public administrations. The project will allow the HES-SO to strengthen its importance in the field of eGovernment and become a key actor in this context. It will also foster the collaboration with public and private organizations, opening the way to future projects and mandates opportunities.

Making sense of radiomics :
Scientific paper ArODES
insights on human–AI collaboration in medical interaction from an observational user study

Jakub Mlynár, Adrien Depeursinge, John O. Prior, Roger Schaer, Alexandre Martroye de Joly, Florian Evéquoz

Frontiers in Communication,  2024, 8

Link to the publication

Summary:

Technologies based on “artificial intelligence” (AI) are transforming every part of our society, including healthcare and medical institutions. An example of this trend is the novel field in oncology and radiology called radiomics, which is the extracting and mining of large-scale quantitative features from medical imaging by machine-learning (ML) algorithms. This paper explores situated work with a radiomics software platform, QuantImage (v2), and interaction around it, in educationally framed hands-on trial sessions where pairs of novice users (physicians and medical radiology technicians) work on a radiomics task consisting of developing a predictive ML model with a co-present tutor. Informed by ethnomethodology and conversation analysis (EM/CA), the results show that learning about radiomics more generally and learning how to use this platform specifically are deeply intertwined. Common-sense knowledge (e.g., about meanings of colors) can interfere with the visual representation standards established in the professional domain. Participants' skills in using the platform and knowledge of radiomics are routinely displayed in the assessment of performance measures of the resulting ML models, in the monitoring of the platform's pace of operation for possible problems, and in the ascribing of independent actions (e.g., related to algorithms) to the platform. The findings are relevant to current discussions about the explainability of AI in medicine as well as issues of machinic agency.

Stopping aside :
Scientific paper ArODES
pedestrians' practice for giving way to a self-driving shuttle

Jakub Mlynár, Grace Eden, Florian Evéquoz

Social Interaction. Video-Based Studies of Human Sociality,  2023, vol. 6, no. 1

Link to the publication

Summary:

Contributing to interactionist studies of walking and to research on human-machine interaction, this article draws on video recordings of a self-driving shuttle being tested as a means of public transportation. The analytical focus is on yielding as achieved through the practice of pedestrians’ stepping aside, stopping, and letting the shuttle pass. The paper examines and describes how solitary pedestrians “stop aside” as well as how mobile formations of multiple persons take part in the practice. Finally, it discusses stopping aside as a social action that is often followed by displays of gratitude and reflects on this facet with regard to automated vehicles. In the context of this special issue, the central claim advanced is that agency reflexively emerges from the organized and sequential character of the situation and is grounded in assemblages of human and technological aspects, rather than originating in clearly distinguishable singular actors or agents.

Summary:

Background : Radiomics, the field of image-based computational medical biomarker research, has experienced rapid growth over the past decade due to its potential to revolutionize the development of personalized decision support models. However, despite its research momentum and important advances toward methodological standardization, the translation of radiomics prediction models into clinical practice only progresses slowly. The lack of physicians leading the development of radiomics models and insufficient integration of radiomics tools in the clinical workflow contributes to this slow uptake. Methods We propose a physician-centered vision of radiomics research and derive minimal functional requirements for radiomics research software to support this vision. Free-to-access radiomics tools and frameworks were reviewed to identify best practices and reveal the shortcomings of existing software solutions to optimally support physician-driven radiomics research in a clinical environment. Results : Support for user-friendly development and evaluation of radiomics prediction models via machine learning was found to be missing in most tools. QuantImage v2 (QI2) was designed and implemented to address these shortcomings. QI2 relies on well-established existing tools and open-source libraries to realize and concretely demonstrate the potential of a one-stop tool for physician-driven radiomics research. It provides web-based access to cohort management, feature extraction, and visualization and supports “no-code” development and evaluation of machine learning models against patient-specific outcome data. Conclusions : QI2 fills a gap in the radiomics software landscape by enabling “no-code” radiomics research, including model validation, in a clinical environment. Further information about QI2, a public instance of the system, and its source code is available at https://medgift.github.io/quantimage-v2-info/. Key points: - As domain experts, physicians play a key role in the development of radiomics models. - Existing software solutions do not support physician-driven research optimally. - QuantImage v2 implements a physician-centered vision for radiomics research. - QuantImage v2 is a web-based, “no-code” radiomics research platform.

Getting into the engine room :
Scientific paper ArODES
a blueprint to investigate the shadowy steps of AI ethics

Johan Rochel, Florian Evéquoz

AI society,  2021, vol. 36, no. 2, pp. 609-622

Link to the publication

Summary:

Enacting an AI system typically requires three iterative phases where AI engineers are in command: selection and preparation of the data, selection and configuration of algorithmic tools, and fine-tuning of the different parameters on the basis of intermediate results. Our main hypothesis is that these phases involve practices with ethical questions. This paper maps these ethical questions and proposes a way to address them in light of a neo-republican understanding of freedom, defined as absence of domination. We thereby identify different types of responsibility held by AI engineers and link them to concrete suggestions on how to improve professional practices. This paper contributes to the literature on AI and ethics by focusing on the work necessary to configure AI systems, thereby offering an input to better practices and an input for societal debates.

Link to the publication

Summary:

Annotations produced by analysts during the exploration of a data visualization are a precious source of knowledge. Harnessing this knowledge requires a thorough structure of annotations, but also ameans to acquire themwithout harming user engagement. Themain contribution of this article is amethod, taking the formof an interface, that offers a comprehensive “subject-verb-complement” set of steps for analysts to take annotations, and seamlessly translate these annotations within a prior classification framework. Technical considerations are also an integral part of this study: through a concrete web implementation, we prove the feasibility of our method, but also highlight some of the unresolved challenges that remain to be addressed. After explaining all concepts related to our work, from a literature review to JSON Specifications, we follow by showing two use cases that illustrate how the interface can work in concrete situations. We conclude with a substantial discussion of the limitations, the current state of the method and the upcoming steps for this annotation interface.

Summary:

Dans le domaine de la mobilité, l’arrivée de systèmes de transport autonome prend de l’ampleur. Dès lors, il est capital de prendre en compte les facteurs qui auront une incidence sur l’adoption de ces systèmes par les utilisateurs. De manière générale, pour que la mise en oeuvre d’une technologie soit réussie, le service fourni par celle-ci doit améliorer le confort et la sécurité de l’utilisateur. Nous présentons dans cet article les résultats d’immersion de 21 utilisateurs de la navette autonome de la ville de Sion en Suisse. Cette étude est la première étape d’une approche de design de service afin d’optimiser les navettes autonomes en tant que service public de mobilité.

Which lobby won the vote ? :
Book chapter ArODES
visualizing influence of interest groups in Swiss Parliament

Florian Evéquoz, Hugo Castanheiro

Dans Lindgren, Ida, Electronic government  (13 p.). 2019,  Cham : Springer

Link to the publication

Summary:

Members of national parliaments (MPs) often have ties to interest groups, or ‘lobbies’, which might try to influence policies. In order to quantify the influence of lobbies on parliamentary decisions, we design an online platform that allows users to explore votes results, focusing on how interest groups members voted, in order to identify which lobbies voted for or against a given measure and in which proportion. We apply this approach to the specific case of the Swiss Federal Parliament. To achieve this, we build a database that combines two sources of openly available data: (1) a register of politicians’ interest ties, main- tained by Lobbywatch.ch, an association dedicated to the monitoring of Swiss politicians’ interest ties and (2) the individual votes results in the Swiss Federal Parliament, accessible through a web-service provided by the parliamentary service of the Swiss government. Our platform allows users to explore the following perspectives of the data: (1) general information about lobbies (e.g. size, domains), (2) individual votes results, with a drill-down by lobby that shows the distribution of votes in each interest group for each specific vote, and (3) overall (dis)agreement of individual MPs with their party and lobbies across all considered votes. We believe that such an exploration platform can be a powerful tool to help quantify the influence of lobbies in politics. Indeed, a qualitative evaluation of the prototype was conducted with 7 domain experts (5 journalists and 2 politicians). They were all able to complete successfully the submitted tasks. They rated its usability and usefulness as rather high (mean respectively 7.4/10 and 6.8/10). Moreover, most of them reported that such a platform has the potential to increase the accountability of politicians towards the people and consequentially to raise the trust of the population in their elected representatives.

Pedestrians and visual signs of intent :
Scientific paper ArODES
towards expressive autonomous passenger shuttles

Himanshu Verma, Guillaume Pythoud, Grace Eden, Denis Lalanne, Florian Evéquoz

Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies,  2019, vol. 3, no. 3, article no. 107

Link to the publication

Summary:

Autonomous Passenger Shuttles (APS) are rapidly becoming an urban public transit alternative. Traversing populous commercial and residential centers, these shuttles are already operating in several cities. In the absence of a human driver and embedded means of communicating the autonomous shuttle's intent, the task of seamlessly navigating crosswalks and pedestrian-friendly zones becomes a challenging pursuit for pedestrians. We contribute to the emerging notion of AV-Pedestrian Interaction by examining the context of autonomous passenger shuttles (APS) in real-world settings, and by comparing four different classes of visual signals -- namely instructional, symbolic, metaphorical, and anthropomorphic -- designed to communicate the shuttle's intentions. Following a participatory methodology involving local residents and public transport service provider, and working within the framework of inflexible road traffic regulations concerning the operation and testing of autonomous vehicles, we conducted a participatory design workshop, a qualitative, and a survey study. The findings revealed differences across these four classes of signals in terms of pedestrians' subjective perceptions. Anthropomorphic signals were identified as the preferred and effective modality in terms of pedestrians' interpretation of the communicated intent and their perceived sense of attention, confidence, and calmness. Additionally, pedestrians' experiences while judging the intention of transitionary vehicular states (starting/slowing) were reported as perplexing and evoked stress. These findings were translated into design and policy implications in collaboration with other stakeholders, and exemplify a viable way for assimilating human factors research in urban mobility.

Electronic Government and Electronic Participation: Joint Proceedings of Ongoing Research, Posters, Workshops and Projects of IFIP eGOV and ePart 2014,  octobre 2014, vol. 21, pp. 197-205

Link to the publication

Summary:

Information and Communication Technologies provide public administrations new ways to meet their users’ needs. At the same time, e- Government practices support the public sector in improving the quality of service provision and of its internal operations. In this paper we discuss the impacts of digitization on the management of administrative procedures. The theoretical framework and the research model that we will use in this study help us tackle the question of how digitization transforms administrative procedures as, for example, in terms of time and roles. The multiplicity of institutions involved in issuing building permits led us to consider this administrative procedure as a very interesting case study. An online survey was first addressed to Swiss civil servants to explore the field, and here we present some of its results. We are currently undertaking an in-depth case study of the building permit procedures in three Swiss Cantons, which we will also present in this paper. We will conclude with a discussion and the future steps of this project.

Summary:

Purpose This paper addresses the complex relationships between AI, medical education and research, embodied in QuantImage v2, a software platform for radiomics. Existing research has indicated lack of user studies and physicians’ low confidence in the diagnosis and treatment planning proposed by AI models. In this context, we explore how QuantImage, designed as a tool for radiomics research, can be repurposed for education. Methods Specifying the possible educational uses and required technical adjustments of QuantImage, we have organized user studies in the form of collective trial sessions at the Centre hospitalier universitaire vaudois (CHUV) in Lausanne, Switzerland. These 13 sessions, in which pairs of novice users worked with the platform together with an expert tutor, have been video recorded, transcribed, and analyzed in detail, focusing on troubles that participants encountered. Results Based on the analyses, we formulate actual and potential design implications. Actual changes already implemented in the platform include a paradigm shift in feature selection and highlighting central elements of the user interface, which are both motivated by the aims of making the work with QuantImage more accessible to users with varying levels of expertise. Potential improvements include implementation of three different modes for the use of the platform: basic, advanced, and tutorialmode, with the last one reflecting specific needs of higher education and broadening the relevance of the obtained skills beyond the particular platform. Conclusions Understanding the practical work with AI-based models is key for making radiomics respectable in oncology and radiology and overcoming the resistance to their adoption in clinical practice. Taking into account that different user groups and use scenarios place different requirements on the design of QuantImage opens the possibility of using the platform to leverage timely reflections of the practical role of AI in medicine.

Summary:

Significant and rapid advancements in cancer research have been attributed to Artificial Intelligence (AI). However, AI’s role and impact on the clinical side has been limited. This discrepancy manifests due to the overlooked, yet profound, differences in the clinical and research practices in oncology. Our contribution seeks to scrutinize physicians’ engagement with AI by interviewing 7 medical-imaging experts and disentangle its future alignment across the clinical and research workflows, diverging from the existing “one-size-fits-all” paradigm within Human-Centered AI discourses. Our analysis revealed that physicians’ trust in AI is less dependent on their general acceptance of AI, but more on their contestable experiences with AI. Contestability, in clinical workflows, underpins the need for personal supervision of AI outcomes and processes, i.e., clinician-in-the-loop. Finally, we discuss tensions in the desired attributes of AI, such as explainability and control, contextualizing them within the divergent intentionality and scope of clinical and research workflows.

Summary:

We examine the technological aspects of political collaborative practices in one of the first studies of participatory constitution writing in the course of its progression. In particular, we examine how digital collaborative and communicative tools can facilitate (or inhibit) the permeation of boundaries, which manifest through the differences in political ideologies and partisan beliefs. Our study is grounded in interviews with 15 members of the Constituent Assembly in the canton of Valais, Switzerland, and its primary contribution is in constructing a fine-grained contextualized understanding of political collaborations, their evolution, and their relationship with collaborative tools. Our findings demonstrate the centrality of versatile and widely available digital tools (such as WhatsApp and Google Docs) in political work. In addition, elected lawmakers prefer tools that allow them to organize their collaborative and communicative actions based on dynamic social boundaries, and their need for asynchronous work practices. We observed a tendency of simultaneously using multiple digital tools to accomplish specific political objectives, and leveraging them in plenary sessions for strategic advantages. On the one hand, collaborative tools enabled strategic advantages by selective permeation of boundaries across political ideologies. On the other hand, lack of awareness about boundaries between ‘private’ and ‘public’ on social networks were considered as privacy blind spots. By focusing on boundaries of different kinds, our paper elucidates how the introduction of digital technologies into political process transforms the long-established categories, distinctions and divisions that are often taken for granted.

Summary:

Driverless Passenger Shuttles are operating as a public transport alternative in the town of Sion, Switzerland since June'16, and traversing the populated commercial and residential zones of the city center. The absence of a human driver and the lack of dedicated AV-pedestrian interface makes it challenging for road users (pedestrians, cyclists, etc.) to understand the intent or operational state of the vehicle and negotiate road usage. In this article, we present a co-design study aimed at informing the design of interactive communication means between pedestrians and autonomous vehicles (AVs). Conducted in two stages with the local community --which is accustomed to the AV's ecosystem and has interacted with it on a daily basis-- the study highlights the interactive experiences of road users, and furnishes contextualized design guidelines to bridge the communication with the pedestrians.

Summary:

The integration of autonomous vehicles (AVs) onto public roads presents both technical and social challenges. Public understanding and acceptance of AVs requires engagement with people who live in, work at or visit cities where they are deployed on public road networks. We investigate the impact of one of the first placements of AV passenger transport on public roadways: the Sion <>. This late-breaking research presents preliminary results from interviews with local shopkeepers, residents, pedestrians and drivers to understand their attitudes and opinions of the shuttle. We also discuss video-based fieldwork that demonstrates how drivers negotiate next moves with one another through their windscreens using embodied signals such as gestures, lip-reading, and head nods to coordinate and manage a traffic situation. Finally, we consider the implications for how fully autonomous vehicles might be designed to take into account the subtle negotiations that road users engage in to coordinate with one another.

Summary:

Passenger acceptance is a key factor for the successful integration, uptake and use of autonomous vehicles (AVs) in the domain of public transpor-tation. Especially knowing opinions and attitudes around safety, comfort and convenience. We discuss a pilot study conducted as part of a larger research project where AVs are being tested to transport members of the general public on a specified route with designated stops. We present preliminary findings of fieldwork conducted where people were asked their opinions and attitudes both before and after riding on an AV shuttle as a passenger for the first time. This allows us to compare user expectation beforehand with actual experience after-wards.

Summary:

L'évaluation naturaliste de prototype est une approche utilisée pour évaluer (1) le potentiel pratique d'une technologie dans des contextes et des situations du monde réel (son utilité) et (2) son interface (son utilisabilité). Cet article présente une nouvelle technique d'évaluation de prototype, le Modèle d’Evaluation de l’Activité (MEA) (Activity Evaluation Framework – AEF), qui s’inspire d’orientations sociologiques dont l’ethnométhodologie (EM). Le modèle repose sur la vidéo pour analyser la « parole-en-interaction » des participants interagissant avec un prototype technologique. Nous discutons l'utilisation du MEA comme une technique qualitative systématique et robuste pour l'évaluation à la fois de l'utilité et de l’utilisabilité de prototypes et nous l’illustrons au moyen d’un cas d’utilisation dans une installation muséale de réalité virtuelle et augmentée.

Summary:

Most of today's commercial companies heavily rely on social media and community management tools to interact with their clients and analyze their online behaviour. Nonetheless, these tools still lack evolved data mining and visualization features to tailor the analysis in order to support useful marketing decisions. We present an original methodology that aims at formalizing the marketing need of the company and develop a tool that can support it. The methodology is derived from the Cross-Industry Standard Process for Data Mining (CRISP-DM) and includes additional steps dedicated to the design and development of visualizations of mined data. We followed the methodology in two use cases with Swiss companies. First, we developed a prototype that aims at understanding the needs of tourists based on Flickr and Instagram data. In that use case, we extend the existing literature by enriching hashtags analysis methods with a semantic network based on Linked Data. Second, we analyzed internal customer data of an online discount retailer to help them define guerilla marketing measures. We report on the challenges of integrating Facebook data in the process. Informal feedback from domain experts confirms the strong potential of such advanced analytic features based on social data to inform marketing decisions.

Summary:

This article presents a methodology based on design thinking and user experience design methods for creating what we call `people-aware' IoT applications, where user needs, not technological opportunities, drive the development. This methodology is divided into 7 steps: discovery, capturing, research, design, prototype, evaluate and refine. The tools used include conventional user experience procedures such as problem identification, group brainstorming, surveys, or interviews, mixed with more IoT-specific design specificities. The results of the methodology include well-described and user-oriented scenarios meeting user's needs and also a complete toolbox to assist the implementation and the testing of abovementioned scenarios in an IoT perspective. The article describes the methodology in detail with the help of a use case conducted in a business environment available for the project that leads to the identification and partial design of concrete people-aware IoT applications in the context of a smart meeting room.

Summary:

In this case study, we combine the user centered design and the gamification design methodologies to design the eCH-BPM portal, a platform designed to enable public administration of Switzerland to publish and share their business process documentation in BPMN and discuss best practices in introducing Business Process Management (BPM) practices in the administration. The overall goal of the platform is to foster the development of a BPM mindset in the Swiss administration, in order to optimize and modernize the operations and deliver quality services. However, actively sharing process descriptions and template business processes, as well as actively participating in the community of practice for BPM in the public administration requires motivation and engagement on the part of public servants. A key factor in the success of the platform will be its ability to create, retain and expand a critical users’ base. To address this issue, we designed the platform using user-centered design and gamification design, developing an original framework to combine both approaches that can be applied to the design of other e-government services. Both user centered design and gamification design, individually, are known to benefit various aspects and types of e-services and applications. Here, we present a unified methodology by combining both methodologies, for the design of e-government applications. We believe that User Centered Design and Gamification design can help improve e-government services, for example, by increasing participation and increasing interest in the service, and following the combined methodology will help us do so. The case study highlights the mistakes made, and the lessons learnt while designing the platform for researchers to further test and build on the proposed methodology. As an example we learnt that virtual rewards, which form the core of the gamification framework have to be meaningful in order to work effectively. Simply using a gamut of badges (virtual rewards) without keeping the user motivations and behavior in mind only leads to building an ineffective system.

Summary:

With the ever-rising energy usage, costs for the current and upcoming years is exponentially growing and unfortunately is being manage with poor or non-existing management tools and/or methods. In Switzerland the energy management is gaining interests the last decades, especially in the public sectors where a mine of data to be processed exists, but sadly is not exploited enough. Consequently, data remains scattered into silos and therefore prevented from being correlated automatically. We believe that these data can be mapped and put in perspective providing interesting information and enough knowledge helpful for decision makers. This paper presents an ongoing experiment in Swiss municipalities to analyze the current situation and design and propose an approach for energy managing by dashboards.
