Interactive visualization has become a popular approach to support decision makers coping with complex decision problems in the commercial world. However, it is not clear that these interactive visualizations result in better decision making. Human judgment under uncertainty is known to fall victim to a number of biases that result from the heuristics that we employ, yet the design of many interactive...
This paper discusses the results of four empirical evaluations that assess the effects that visualizing system meta-information have on decision-making, particularly on confidence, trust, workload, time and performance. These four case studies correspond to the analysis of (1) the effects that visualizing uncertainty associated with sensor values (position, speed, altitude, etc. and track quality)...
Taken in isolation, algorithmic "data sciences" approaches and human-centred "visual analytics" methods hold great promise for operationalizing archival datasets and streaming real-time data in support of strategic and operational decision-making across a broad range of human activities.
Data quality metadata (QM) is the set of quality measurements associated with the data. Literature has demonstrated that the provision of QM can improve decision performance. In this paper, we examine how information systems, specifically, decision support systems can be designed to help users make better use of QM, using a two-stage approach. In stage-1, we develop a theoretical model and validate...
In this study we examine the impact of providing data quality (DQ) metadata together with its associated data, on decision outcomes. Literature has shown that, when DQ metadata is provided to decision-makers along with the data, it is used, and when used, it can affect decision outcomes. Two key issues have not received sufficient attention: (a) does DQ metadata improve decision outcomes? (b) What...
Geovisualization is both a process for leveraging the data resources to meet scientific and societal needs and a research field that develops visual methods and tools to support a wide array of geospatial data applications. While researchers have made substantial advances in geovisualization over the past decade, many challenges remain. To support real-world knowledge construction and decision making,...
