Puhekaverina botti
2020
Viestivät tekoälyt eli luonnollisella kielellä käytävään keskusteluun kykenevät algoritmit ovat yhä tyypillisempiä vuorovaikutuskumppaneita erilaisilla teknologisilla alustoilla. Yksi tyypillinen viestivän tekoälyn muoto on botti: automaattinen ohjelma, joka käyttää verkkopalvelun käyttäjätiliä tavallisen käyttäjän tavoin ja suorittaa yksinkertaisia toimintoja tai viestii. Tyypillisesti botit tavalla tai toisella pyrkivät näyttäytymään ihmiskäyttäjinä, tai ainakin niille ohjelmoidaan ja suunnitellaan ihmisenkaltaisia piirteitä.Artikkeli tarkastelee bottien roolia vuorovaikutuskumppaneina sisäisessä ja julkisessa mediatilassa kytkeytymällä tuoreeseen ihmis-koneviestinnän tutkimusalaan.

Meeting others—supporting situation awareness on the WWW
2001
Abstract World Wide Web (WWW) techniques provide a simple interface, which is accessible almost everywhere. The WWW supports document sharing and information retrieval, but has no tools for direct user interaction, simply because the mechanisms to support user awareness are missing. The aim of this paper is twofold. First, we present general concepts of situation awareness, which concerns the user interaction on the WWW platform, and a theoretical framework, which is used in examining existing awareness support systems. Second, we provide an analysis of PeopleAwarenessEngine, which supports situation awareness and enables user communication and collaboration on the WWW.
Emotion rating from short blog texts
2008
Being able to automatically perceive a variety of emotions from text alone has potentially important applications in CMC and HCI that range from identifying mood from online posts to enabling dynamically adaptive interfaces. However, such ability has not been proven in human raters or computational systems. Here we examine the ability of naive raters of emotion to detect one of eight emotional categories from 50 and 200 word samples of real blog text. Using expert raters as a 'gold standard', naive-expert rater agreement increased with longer texts, and was high for ratings of joy, disgust, anger and anticipation, but low for acceptance and 'neutral' texts. We discuss these findings in ligh…
Developing web-based learning resources in school education: a user-centered approach
2010
Published version of an article from the journal:Interdisciplinary Journal of Knowledge and Learning Objects. Also available from the publisher:http://www.ijello.org/Volume6/IJELLOv6p115-135Hadjerrouit688.pdf Web-based learning resources (WBLRs) are potentially powerful tools for enhancing teachingand learning processes in school education. They can provide teachers and learners with a widerange of new and exciting experiences that are not possible in a traditional classroom. However,WBLRs are still the domain of technical and software experts rather than teachers and learners.As a result, much of the development of WBLRs is carried out without a true understanding ofissues pertinent to lea…
Role Scripting as a Tool to Foster Transactivity of Asynchronous Student Discussions
2021
Transactivity of student discussions is crucial in computer-supported collaborative learning (CSCL). However, CSCL learners often lack well-developed argumentation and negotiation skills, which makes it challenging for them to engage in and maintain a transactive discussion. Collaboration scripts have been implemented in CSCL contexts and have demonstrated positive effects on students' collaboration and argumentation skills. Yet, the degree of transactivity of student interactions is rarely addressed directly in CSCL research. Employing a qualitative content analysis approach, this study seeks to understand how a role script affects the transactivity of students' argumentative knowledge co-…
Introduction: Reframing Humans and Information Systems
2010
Recent development of information and communication technologies (ICT) provides information systems (IS) designers with new potentialities to build systems for various purposes. The ongoing digital convergence refers to and discloses new views on the interactive reconfiguration of technological and social arrangements on a large scale in the contemporary society (Tilson et al. 2009). In addition to work-related activities, people use new technologies for increasingly diverse purposes, for example organizing their domestic affairs, for finding information and e-services, and for staying in touch with their friends and relatives (Lyytinen and Yoo 2002; Sorensen and Yoo 2005; Iivari et al. 201…
Following the WCAG 2.0 techniques: Experiences from designing a WCAG 2.0 checking tool
2012
Published version of a chapter in the book: Computers Helping People with Special Needs. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-31522-0_63 This paper presents a conceptual analysis of how the Web Content Accessibility Guidelines (WCAG) 2.0 and its accompanying documents can be used as a basis for the implementation of an automatic checking tool and the definition of a web accessibility metric. There are two major issues that need to be resolved to derive valid and reliable conclusions from the output of individual tests. First, the relationship of Sufficient Techniques and Common Failures has to be taken into account. Second, the logical combination of the…
Semantic Annotation and Retrieval of Services in the Cloud
2013
Recently, the economy has taken a downturn, which has forced many companies to reduce their costs in IT. This fact has, conversely, benefited the adoption of innovative computing models such as cloud computing, which allow businesses to reduce their fixed IT costs through outsourcing. As the number of cloud services available on the Internet grows, it is more and more difficult for companies to find those that can meet their needs. Under these circumstances, enabling a semantically-enriched search engine for cloud solutions can be a major breakthrough. In this paper, we present a fully-fledged platform based on semantics that (1) assist in generating a semantic description of cloud services…
Wortbildungsmuster in Hashtags in politischen Tweets: doppelte Kurzformen? Frz.-Deutsch kontrastiv
2018
International audience; Der Beitrag untersucht Wortbildungstendenzen in zwei Korpora politischer Tweets auf Deutsch und Französisch. Er geht davon aus, dass soziale Medien neue Kommunikationsformen mit sich gebracht haben, die mehrere für linguistische Fragestellungen interessante Merkmale aufweisen, darunter – was Twitter betrifft – die (allmähliche) Anpassung der Sprache und der Sprachgewohnheiten an die Kürze, u.a.m. durch Auslassungen, Zusammenschreibungen, Abkürzungen, Multimodalität... Ziel ist es, in diesem Rahmen folgende drei Themenkomplexe anzuschneiden: (i) Lassen sich gewisse Wortbildungstendenzen beobachten? (ii) Wenn ja, welche Funktionen können diesen Formen zugeordnet werden…
