Peer review is the "gold standard" for evaluating journal and conference papers, research proposals, on-going projects and university departments. However, it is widely believed that current systems are expensive, conservative and prone to various forms of bias. One form of bias identified in the literature is “social bias” linked to the personal attributes of authors and reviewers. To quantify...

Current tools for exploratory data analysis (EDA) require users to manually select data attributes, statistical computations and visual encodings. This can be daunting for large-scale, complex data. We introduce Foresight, a visualization recommender system that helps the user rapidly explore large high-dimensional datasets through “guideposts.” A guidepost is a visualization corresponding to a...

Facilitating engaging user experiences is essential in the design of interactive systems. To accomplish this, it is necessary to understand the composition of this construct and how to evaluate it. Building on previous work that posited a theory of engagement and identified a core set of attributes that operationalized this construct, we constructed and evaluated a multidimensional scale to mea...

Graph layout is the process of creating a visual representation of a graph through a node-link diagram. Node-attribute graphs have additional data stored on the nodes which describe certain properties of the nodes called attributes. Typical force-directed representations often produce hairball-like structures that neither aid in understanding the graph’s topology nor the relationship to its att...

This paper proposes a new hybrid multiattribute decision making (MADM) model which deals with the interactions that usually exist between hostel attributes in the process of measuring the students’ satisfaction towards a set of hostels and identifying the optimal strategies for enhancing their satisfaction. The model uses systematic random stratified sampling approach for data collection purpos...

Information Visualisation is an emerging discipline that concerns the design of interactive computer systems that provide the user with a visual model of abstract data. Information Visualisation implies a mapping from the data attributes to the units of visual perception. Information Sonification is an embryonic field that uses sound rather than imagery to present abstract data. Information Son...

Interest in interpreting this data has spawned an active market for software packages that summarize and analyze this data, providing histograms, pie graphs, and other charts summarizing usage patterns. While useful, these summaries obscure useful information and restrict users to passiv...

The Automated Network Games Enhancement Layer (ANGEL) project aims to leverage machine learning techniques to automate the classification and isolation of interactive (e.g. games, voice over IP) and noninteractive (e.g. web) traffic. This information is then used to dynamically reconfigure the network to improve the Quality of Service provided to the current interactive traffic flows and subseq...

This paper presents a method for combined interactive filtering and visualization of volumetric data. The user can set the filter parameters of a shape preserving class of morphological filters, called connected filters, efficiently. The filters work by computing some attribute describing the shape or size for each connected component, and then deciding which to keep based on some threshold. We...
