Personalized distance learning based on multiagent ontological system
2004
The paper presents architecture of a personalized distance learning system based on multiagent technology and ontological modelling of students' profiles. Delocalization of a student data in the system is achieved by software agents, which assumed to be distributed at different platforms. These platforms operate as separate Web services and use the ACL (agent communication language) for the data transfer. In this paper the algorithm is proposed, according to which the multiagent ontological system for personalized distance learning (MOSPDL) solves the tasks of distant learning process automation, which assume utilization of the ontological models of students' and learning resources' profile…
An Integrated Framework for Meta Modeling
2006
Meta modeling is an essential means to systematize, formalize, standardize, integrate, analyze and compare models, techniques, methods and tools. Numerous fields, such as databases, software engineering, software architectures, semantic web, computer-aided tools and method engineering, have benefited from it. The importance of meta modeling is ever increasing along with the emergence of novel approaches, architectures, techniques and languages based on UML and MDA. This paper presents a framework to integrate and compare divergent conceptions of meta modeling in databases, software engineering, and information systems development. The framework is applied to analyze and compare conceptions …
Visualising knowledge from chat debates in argument diagrams
2010
This study investigates whether combining chat discussion and construction of an argument diagram stimulates students to formulate new ideas in practising argumentation. In this study, 16 secondary school students discussed vivisection and gender equality in pairs using both free and structured chat tools. In structured chat, the students selected and completed partial sentences provided by the computer. After the discussion, they jointly constructed either argument diagrams freely based on the previous discussions with an Internet tool or modified a diagram the computer had constructed automatically during the structured chat. The freely constructed diagrams contained more of the students'…
A Latent Class Analysis of Spanish Travelers’ Mobile Internet Usage in Travel Planning and Execution
2014
A study of 476 Spanish travelers found mixed interest and use for the many travel-related mobile internet services that are involved in planning and executing a trip. The findings indicate that these Spanish respondents can be classified into four segments based on the timing of using mobile apps for over a dozen activities involved in travel planning and execution: Savvies, Planners, Opportunists, and Low-techs. Each segment exhibits distinct patterns of mobile internet services usage. Savvies tend to be heavy mobile device users both before and during their trip, while Planners make heavy use of mobile devices in advance of but not during their trip. The Opportunists show a pattern oppos…
A reflective characterisation of occasional user
2017
This work revisits established user classifications and aims to characterise a historically unspecified user category, the Occasional User (OU). Three user categories, novice, intermediate and expert, have dominated the work of user interface (UI) designers, researchers and educators for decades. These categories were created to conceptualise user's needs, strategies and goals around the 80s. Since then, UI paradigm shifts, such as direct manipulation and touch, along with other advances in technology, gave new access to people with little computer knowledge. This fact produced a diversification of the existing user categories not observed in the literature review of traditional classificat…
Mobile Electronic Commerce: Emerging Issues
2000
There are many definitions for Mobile Electronic Commerce (M-Commerce). We define M-Commerce as any type of transaction of an economic value having at least at one end a mobile terminal and thus using the mobile telecommunications network. The Wireless Application Protocol (WAP) plays an important role in m-commerce by optimizing Internet standards for the constraints of the wireless environment and thus bridging the gap between Internet and mobile world. Mobile Network Operators can play a major role in m-commerce by being strategically positioned between customers and content/service providers. In this paper we investigate the roles the operator can play in m-commerce and discuss respecti…
On marrying ontological and metamodeling technical spaces
2007
In software engineering, the use of models and metamodeling approaches (e.g., MDA with MOF/UML) for purposes such as software design or software validation is an established practice. Ontologies constitute domain models formalized using expressive logic languages for class definitions and rules. Hence, when seen from an abstract point of view, the two paradigms and their various technological spaces seem closely related. However, in the state-of-the-art research and practice the two technologies are just beginning to converge and the relationship between the two is still under exploration. In this paper, we give an outline of current ontology technologies, such as the Semantic Web standards…
New ways in fostering self-regulated learning at university: How effective are web-based courses when compared to regular attendance-based courses?
2020
Abstract. Self-regulated learning is essential for studying successfully at university. However, students often show deficits in their ability to learn in a self-regulated way. Consequently, it has become crucial to foster students' self-regulated learning at university. The effectiveness of such courses has primarily been investigated in regular class contexts that require physical attendance. However, web-based course formats are currently gaining in importance. Web-based courses have several advantages (e. g., that students can decide when and where they want to study). The question of whether a web-based course is as effective as an attendance-based one has yet to be answered. In a ran…
Increasingly emotional design for growingly pragmatic users? A report from Finland
2012
Researchers and practitioners in the field of information and communication technologies (ICT) have for a while been embracing the concepts of user and consumer experience as well as emotions in design, encouraging the industry to emphasise hedonic and symbolic qualities of products and services, over and beyond their utilitarian characteristics. However, the idea that mobile phone users, for instance, seek increasingly experience-rich, personalised products can not be taken for granted. Therefore, it is valuable to investigate the degree to which users really share designers' increasingly socio-emotional stances. The presented longitudinal study investigated users' mobile phone-related pro…
Website quality and internal business factors: An empirical investigation in the Italian wine industry
2016
Purpose The purpose of this paper is dual. The first is to assess the quality of websites of Italian wineries, using the Web Assessment Index (WAI), and compare e-commerce and e-marketing websites. The second is to verify the existence of a relationship between the website quality and business revenue, on one hand, and the characteristics of managers, on the other. Design/methodology/approach A two-step survey was carried out to respond to the aims of the study. First, a sample of wineries was contacted to capture information on both the wineries and managerial characteristics. On the basis of the observed data, a second step of the analysis was performed taking into consideration 84 winer…
