In this paper, we present a generic model to enrich user profiles by means of contextual and temporal information. This reflecting the current interests of these users in every period of time defined by a search session, and infers data freshness. We argue that the annotation of resources gives more transparency on users' needs. Based on this idea, we integrate social tagging in order to exploit part...
This study investigated the effects of teaching history of computing with videos of historical figures. Augmented reality (AR) techniques were applied to assist student accessing the videos of historical figures while reading a printed textbook. Whenever a student was interested in a historical figure, one could use a tablet PC to scan the figure's picture, and the corresponding video about the person...
This paper presents the design, implementation, and reflections of students and faculty of an innovative integrated course (taught in Spring 2012) that combined seemingly disparate topics from engineering and the humanities. The primary goal of the course was to promote the growth of intrinsically motivated students who internalize the value of their technical work, connect their technical work to...
This paper is focused on using computer timeline based interfaces in the domain of history learning. The paper explains what kind of problems do historians and learners face when they deal with chronologically ordered historical information. We review existing approaches and software tools that support timelines. Based on the timeline metaphor ontological model, we examine major features of existing...
Past analysis has considered query reformulation primarily from the perspective of individual Web searches. Findings from a recent study suggest ways that collaboration during the search process influences how users generate new terms for query reformulation.
This article examines the origins and early history of the field of computer engineering in the United States, from the mid-1940s to mid-1950s. The account is based on both primary and secondary sources and draws theory from technology studies and the sociology of professions. The author begins by discussing roles played by engineers and engineering during the development of some of the first high-speed...
This paper introduces a novel concept in the use of game technology and education. Instead of employing gaming technology to create entertaining fictions or develop practical training environments, this paper introduces the concept and demonstrates the practical benefits of docugames for preservation. A docugame for preservation is a simulation that incorporates historical or culturally relevant artifacts...
Graphical passwords provide a promising alternative to traditional alphanumeric passwords. They are attractive since people usually remember pictures better than words. In this extended abstract, we propose a simple graphical password authentication system. We describe its operation with some examples, and highlight important aspects of the system.
In recent years, digital games have been widely used in all fields for learning. Learners are immersed in the context and content, and have increased willingness to participate learning activities which implies the enhancement of learning motivations. The game built in this research was done with Oblivion game engine. First, we design a role-play game script according to the anti-Japanese war history...
The ongoing debate over the merits of classical software engineering (SE) methodologies and agile methodologies has so far resulted in no clear benefits for the SE community. This paper uses the CHAPL framework developed in our previous research to analyse the history of classical SE methodologies and agile methodologies. Our historical analysis focuses on the following three perspectives: the practices,...
The distribution of privileges in domains of subjects defines the protection state of a system. Operations which change this state are themselves authorized by privileges in the current state. This poses an analysis problem of characterizing states which are derivable from a given initial state. Analysis is particularly difficult if creation of new subjects is permitted. Also the need for tractable...
