  • Autentiska och artificiella frågor till svensk text Automatisk frågegenerering jämfört med användares frågor för informationsåtkomst : Authentic and artificial questions to Swedish text Automatically generated questions versus user-generated questions for information access
  • 2015
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • Informationssökning mot ostrukturerade datakällor som fri text är ett av de områden där användargränssnitt med fri formulering i naturligt språk har tagits fram. I ett sådant, eventuellt AI-betonat, system kan några grundläggande svårigheter från användarperspektivet märkas. En sådan svårighet är att en användare inte känner till huruvida en fråga som hon avser att ställa egentligen kan besvaras av den aktuella texten. Denna svårighet, tillsammans med andra, som de kraftiga variationsmöjligheterna för formen för ett giltigt svar på en ställd fråga, riskerar att leda till att användarintrycken av systemtypen blir negativa. De moment som behöver ingå i ett sådant frågebaserat informationssystems funktionssätt måste på något sätt inbegripa en mappning av frågeled i frågan (t.ex. när) till den form och grammatisk funktion som svaret i texten måste ha (för frågan när normalt ett tidsadverbial). Bland annat denna iakttagelse inbjuder till användning av automatisk frågegenerering (question generation, QG). Frågegenerering innebär att frågor som en naturlig text besvarar initialt utvinns av ett program som samlar in dem i explicit form. Tanken för användning i informationssökning är att en användare i gränssnittet enbart ska kunna ställa just dessa frågor, vilka faktiskt besvaras av texten. Denna studie gäller just de frågor som ett automatiskt frågegenereringssystem för svenska kan, och genom vidare utveckling, skulle kunna generera för godtycklig digital svensk text. Även om mängden automatiskt genererade frågor och frågeformuleringar kan bli mycket stor, utrymmesmässigt många gånger större än ursprungstexten, så är det tydligt att den beskrivna metoden för frågegenerering för svenska inte kan och troligen inte heller kommer att kunna förmås att skapa alla de frågor och frågeformuleringar som en vanlig användare skulle anse att en viss text besvarar. Men hur väl fungerar då automatiskt genererade frågor i detta sammanhang? Denna uppsats kretsar kring en användarundersökning där undersökningsdeltagare har ombetts att formulera frågor som texter besvarar, och som anses vara relevanta frågor. Den resulterande samlingen frågor undersöktes och kategoriserades. Resultatet av undersökningens huvudfråga visar att bara 20-25 % av användarnas frågeformuleringar skulle kunna genereras direkt automatiskt med aktuell ansats – utan vissa informationstekniska förbättringar. Uppsatsen föreslår viss ny terminologi för detta outforskade område, bl.a. för att skilja mellan de olika grader av processkrav som generering av olika frågeslag från text kräver.

  • Cognitive Architectures Based on Natural Info-Computation
  • 2022
  • Ingår i: Studies in Applied Philosophy, Epistemology and Rational Ethics. - Cham : Springer. - 2192-6255 .- 2192-6263. ; , s. 3-13, s. 3-13
  • Bokkapitel (refereegranskat)abstract
    • At the time when the first models of cognitive architectures have been proposed, some forty years ago, understanding of cognition, embodiment and evolution was substantially different from today’s. So was the state of the art of information physics, information chemistry, bioinformatics, neuroinformatics, computational neuroscience, complexity theory, self-organization, theory of evolution, as well as the basic concepts of information and computation. Novel developments support a constructive interdisciplinary framework for cognitive architectures based on natural morphological computing, where interactions between constituents at different levels of organization of matter-energy and their corresponding time-dependent dynamics, lead to complexification of agency and increased cognitive capacities of living organisms that unfold through evolution. Proposed info-computational framework for naturalizing cognition considers present updates (generalizations) of the concepts of information, computation, cognition, and evolution in order to attain an alignment with the current state of the art in corresponding research fields. Some important open questions are suggested for future research with implications for further development of cognitive and intelligent technologies.

  • Off the record: The invisibility work of doctors in a patient-accessible electronic health record information service.
  • 2021
  • Ingår i: Sociology of health & illness. - : Wiley. - 1467-9566 .- 0141-9889. ; 43:5, s. 1270-1285
  • Tidskriftsartikel (refereegranskat)abstract
    • In this article, we draw on Michael Lipsky's work on street-level bureaucrats and discretion to analyse a real case setting comprising an interview study of 30 Swedish doctors regarding their experiences of changes in clinical work following patients being given access to medical records information online. We introduce the notion of invisibility work to capture how doctors exercise discretion to preserve the invisibility of their work, in contrast to the well-established notion of invisible work, which denotes work made invisible by parties other than those performing it. We discuss three main forms of invisibility work in relation to records: omitting information, cryptic writing and parallel note writing. We argue that invisibility work is a way for doctors to resolve professional tensions arising from the political decision to provide patients with online access to record information. Although invisibility work is understood by doctors as a solution to government-initiated visibility, we highlight how it can create difficulties for doctors concerning accountability towards patients, peers and authorities.

  • Use of Commercial SaaS Solutions in Swedish Public Sector Organisations under Unknown Contract Terms
  • 2022
  • Ingår i: Electronic Government. - Cham : Springer Nature Switzerland AG. - 9783031150869 - 9783031150852 ; , s. 73-92
  • Konferensbidrag (refereegranskat)abstract
    • Lawful and appropriate use of cloud-based globally provided Software-as-a-Service (SaaS) solutions by a public sector organisation (PSO) for data processing and maintenance of digital assets presupposes an investigation of all relevant contract terms. Having obtained, analysed, and filed all relevant contract terms when using a SaaS solution is a prerequisite for good administration. Identifying and obtaining all relevant contract terms for a SaaS solution involves significant obstacles which in practice may be impossible to overcome for each PSO. This paper addresses how PSOs investigate contract terms prior to adoption, and why PSOs use a globally provided SaaS solution without having identified and obtained all relevant contract terms. Through a review of responses to questions and public documents from Swedish PSOs we analysed how each PSO had investigated contract terms and licences for the Microsoft 365 (M365) solution prior to adoption and use of the solution in each PSO. We find that no PSO had investigated all relevant contract terms prior to use of M365, which implies that each PSO uses M365 under unknown contract terms. Further, we find that all PSOs use M365 for data processing of its digital assets under unknown contract terms and that each PSO has significant dependence and trust in its supplier.

  • Machine Interpretable Representation of Commander's Intent
  • 2008
  • Ingår i: Proceedings of the 13th International Command and Control Research and Technology Symposium (13th ICCRTS).
  • Konferensbidrag (refereegranskat)abstract
    • The Network-Centric approach envisioned in the Global Information Grid enables the interconnection of systems in a dynamic and flexible architecture to support multi-lateral, civilian and military missions. Constantly changing environments require commanders to plan for missions that allow organizations from various nations and agencies to join or separate from the teams performing the missions, depending on the situation, as missions unfold. The uncertainty within an actual mission, and the variety of potential organizations that support the mission after it is underway, makes Command Intent (CI) a critical concept for the mission team. With new and innovative information technologies, CI can now be made available to the team of organizations in a coalition environment. Using a flexible and linguistically based approach for representing CI allows Intent to be interpreted and processed by all participants – both humans and machines. CI representations need to be able to express mission team’s purpose, the anticipated End-State of the mission and desired key tasks. In this work, the expression of CI is developed to enable the structure and dynamics of collaboration support.

  • Medicine At A Distance In Sweden: Spatiotemporal Matters In Accomplishing Working Telemedicine
  • 2011
  • Ingår i: Science Studies. - 0786-3012. ; 24:2, s. 43-62
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper examines the accomplishment of making technology work, using the discourse around telemedicine in Swedish healthcare during 1994-2003. The paper will compare four projects launched in the mid-1990s and policymakers’ visions of healthcare through telemedicine. I will employ a sociotechnical approach developed within Actor-Network Theory that understands functioning technology not as something intrinsic but as an outcome of an ongoing process of negotiations. In the paper, I will extend the sociotechnical approach of what constitutes working technology to include spatiotemporal matters. I will also approach the closely related issue of space that has become a concern of Actor-Network Theory scholars interested in the accomplishment and continued workings of technology as it travels. In this discussion, an emphasis on fixed relations (network space) has been challenged by investigations into changing relations (fluid space). This paper suggests that in order to travel well, technology must be both fixed and fluid.⁰

  • Natural Morphological Computation as Foundation of Learning to Learn in Humans, Other Living Organisms, and Intelligent Machines
  • 2020
  • Ingår i: Philosophies. - Basel, Switzerland : MDPI AG. - 2409-9287. ; 5:3
  • Tidskriftsartikel (refereegranskat)abstract
    • The emerging contemporary natural philosophy provides a common ground for the integrative view of the natural, the artificial, and the human-social knowledge and practices. Learning process is central for acquiring, maintaining, and managing knowledge, both theoretical and practical. This paper explores the relationships between the present advances in understanding of learning in the sciences of the artificial (deep learning, robotics), natural sciences (neuroscience, cognitive science, biology), and philosophy (philosophy of computing, philosophy of mind, natural philosophy). The question is, what at this stage of the development the inspiration from nature, specifically its computational models such as info-computation through morphological computing, can contribute to machine learning and artificial intelligence, and how much on the other hand models and experiments in machine learning and robotics can motivate, justify, and inform research in computational cognitive science, neurosciences, and computing nature. We propose that one contribution can be understanding of the mechanisms of 'learning to learn', as a step towards deep learning with symbolic layer of computation/information processing in a framework linking connectionism with symbolism. As all natural systems possessing intelligence are cognitive systems, we describe the evolutionary arguments for the necessity of learning to learn for a system to reach human-level intelligence through evolution and development. The paper thus presents a contribution to the epistemology of the contemporary philosophy of nature.

  • Exploring User-Suitable Metaphors for Differentially Private Data Analyses
  • 2022
  • Ingår i: Proceedings of the 18th Symposium on Usable Privacy and Security, SOUPS 2022. - 9781939133304 ; , s. 175-193
  • Konferensbidrag (refereegranskat)abstract
    • Despite recent enhancements in the deployment of differential privacy (DP), little has been done to address the human aspects of DP-enabled systems. Comprehending the complex concept of DP and the privacy protection it provides could be challenging for lay users who should make informed decisions when sharing their data. Using metaphors could be suitable to convey key protection functionalities of DP to them. Based on a three-phase framework, we extracted and generated metaphors for differentially private data analysis models (local and central). We analytically evaluated the metaphors based on experts’ feedback and then empirically evaluated them in online interviews with 30 participants. Our results showed that the metaphorical explanations can successfully convey that perturbation protects privacy and that there is a privacy-accuracy trade-off. Nonetheless, conveying information at a high level leads to incorrect expectations that negatively affect users’ understanding and limits the ability to apply the concept to different contexts. In this paper, we presented the plausible suitability of metaphors and discussed the challenges of using them to facilitate informed decisions on sharing data with DP-enabled systems.

  • An industry experiment of academic performance and drop-out in gamified distance education
  • 2021
  • Ingår i: CEUR Workshop Proceedings. - 1613-0073.
  • Tidskriftsartikel (refereegranskat)abstract
    • In an experimental study with 1780 adults who participated in distance education, it was shown that gamification did not have an effect on performance, drop-out rate and pass-rate compared to a control group. Although no effect was shown, descriptive survey data suggests that the students were positive towards having similar gamification in other courses and would likely recommend the course due to the design. While previous research on gamification in online education indicates that gamification can have a positive effect, gamification researchers highlight the importance of context and design for successful implementations. The present study supports the need for context considerations and psychological design in gamifying online education. Furthermore, the present study highlights the need for a more nuanced understanding of engagement measures in gamification research and for more practical frameworks regarding the successful application of gamification in online education.
