Many processes within the oil and gas domain deal with ‘big data’–large sets of multidimensional data. Effectively analyzing these data sets is crucial to understanding the structure and the be­ haviour of oil and gas fields, and to the optimization of hydrocarbons production. However, experts face many challenges while attempting to analyze these data sets due to their high dimensionality, the...

The purpose of the study reported on in this paper was to gain insight into how instructional designers conceptualise learning objects (LOs) and their attributes. It aimed to identify the range and types of conceptualisations of LO attributes held by a group of designers. Data were collected during two phases of semi-structured phone interviews with 10 instructional designers working in Canadia...

During product configuration one of the main challenges is to understand the available options and the consequences of decisions, e.g., in terms of functionality (features) and other characteristics (attributes) of the product. In this paper, we aim to provide support for understanding consequences of configuration decisions, focussing in particular on numerical product attributes resulting fro...

We present a set of interactive techniques for the visual analysis of multi-dimensional categorical data. Our approach is based on multiple correspondence analysis (MCA), which allows one to analyse relationships, patterns, trends and outliers among dependent categorical variables. We use MCA as a dimensionality reduction technique to project both observations and their attributes in the same 2...

Even with simple everyday tasks like online shopping or choosing a restaurant, users are easily overwhelmed with the large number of choices available today, each with a large number of inter-related attributes. We present ExRank, an interactive interface for exploring data that helps users understand the relationship between attribute values and find interesting items in the dataset. Based on ...

Recently, the TODIM$^1$(an acronym in Portuguese of interactive and multi-criteria decision making) method has attracted increasing attention and many researchers have extended it to deal with multiple attribute decision making (MADM) problems under different situations. However, none of them can be used to handle MADM problems with positive, independent, and negative interactions among attribu...

In this article, we define interactive storytelling as a gaming experience where the form and content of the game is customized in real time and tailored to the preferences and needs of the player to maximixe enjoyment. The primary focus of interactive storytelling should not be on the attributes of the technology or characteristics of the medium, such as the AI techniques, planning formalisms,...

Software architecture is an essential early stage in the software design process. In this stage, the architect should give the quality attributes a special consideration because a good level of meeting these attributes can be performed by well-designed architecture. This means that there is a close relationship between quality attributes and software architecture. However, quality attributes ca...

There is a rising trend of data analysis and visualization tasks being performed on a tablet device. Apps with interactive data visualization capabilities are available for a wide variety of domains. We investigate whether users grasp how to effectively interpret and interact with visualizations. We conducted a detailed user evaluation to study the abilities of individuals with respect to analy...
