We developed Toronto Open Data Search to support the ad hoc, interactive discovery of connections or linkages between datasets. It can be used to efficiently navigate through the open data cloud. Our system consists of three parts: a user-interface provided by a Web application; a scalable backend infrastructure that supports navigational queries; and a dynamic repository of open data tables. O...

In this paper, we propose an interactive visualization technique for analysis of results of large-scale software regression testing. Results of this analysis identify the most probable root causes of deterioration or improvement. The provided multi-level visualization solution allows to evaluate project status and efficiently manage project lifecycle. This technique can be used on top of almost...

An object-oriented architecture of a topological data structure that allows high-level interactive two-dimensional (2-D) geometric modeling, called HETOOL, is introduced in this paper. The implementation based on the well-known half-edge for 2-manifold solids, adapted here to deal efficiently with general 2-D models and planar subdivisions, often employed science engineering problems. HETOOL wa...

We present a comprehensive set of conditions and rules to control the correctness aggregation queries within an interactive data analysis session. The goal is extend self-service preparation Business Intelligence (BI) tools automatically detect semantically incorrect aggregate on analytic tables views built by using common operations including filter, project, join, aggregate, union, difference...

AIM We aimed to evaluate an interactive problem-solving approach for teaching traumatology from perspectives of students and consider its implications on Faculty development. METHODS A two hour problem-solving, interactive tutorial on traumatology was structured to cover main topics in trauma management. The tutorial was based on real cases covering specific topics and objectives. Seven tutor...

Traditional interactive system architectures such as MVC [Goldberg, A., 1984. Smaltalk-80: The Interactive Programming Environment, Addison-Wesley Publ.] and PAC [Coutaz, J., 1987. PAC, an implementation model for dialog design. In: Interact’87, Sttutgart, September 1987, pp. 431–436; Coutaz, J., 1990. Architecture models for interactive software: faillures and trends.

Recent theory and experimental work in metapopulations and metacommunities demonstrates that long-term persistence is maximized when the rate at which individuals disperse among patches within the system is intermediate; if too low, local extinctions are more frequent than recolonizations, increasing the chance of regional-scale extinctions, and if too high, dynamics exhibit region-wide synchro...

The purpose of this study is to examine the relationship between local government services and the overall satisfaction of users with the e–recruitment website (e–job website) in Taiwan. A two–dimensional mean value matrix (TDMVM) technique was used to explore the identification, classification, and application of website service quality. The results show that the asymmetrical relationship betw...

Software design is crucial to successful software development, yet is a demanding multi-objective problem for software engineers. In an attempt to assist the software designer, interactive (i.e. human in-the-loop) meta-heuristic search techniques such as evolutionary computing have been applied and show promising results. Recent investigations have also shown that Ant Colony Optimization (ACO) ...
