Understanding Business Analysts' Needs for Data Report Authoring
(The Eurographics Association, 2022)Business analysts often create static, data-driven reports to summarize and communicate findings from marketing dashboards. However, the requirements and workflow for creating data-driven reports in business analytics have ... -
Understanding the Role and Value of Interaction: First Steps
(The Eurographics Association, 2011)Visual Analytics strongly emphasizes the importance of interaction. However, until now, interaction is only sparingly treated as subject matter on its own. How and why interactivity is beneficial to gain insight and make ... -
A Unified Process for Visual-Interactive Labeling
(The Eurographics Association, 2017)Assigning labels to data instances is a prerequisite for many machine learning tasks. Similarly, labeling is applied in visualinteractive analysis approaches. However, the strategies for creating labels often differ in the ... -
The Use of High-Dimensional Visualizations in Explaining Hospital Pricing Patterns
(The Eurographics Association, 2015)The Centers for Medicare and Medicaid Services (CMS) has made public a data set showing what hospitals charged and what Medicare paid for the one hundred most common inpatient stays. By law payments approximate a hospital's ... -
Utilizing Treemaps for Multicriterial Search of 3D Objects
(The Eurographics Association, 2010)We propose a treemap based interface for presentation of search results according to multiple search criteria. Different colors are used to represent the relevance of each item in the database according to the different ... -
Visual Analysis for Hospital Infection Control using a RNN Model
(The Eurographics Association, 2020)Bacteria and viruses are transmitted among patients in the hospital. Infection control experts develop strategies for infection control. Currently, this is done mostly manually, which is time-consuming and error-prone. ... -
Visual Analysis of Advanced Manufacturing Simulations
(The Eurographics Association, 2011)Today's manufacturing companies are faced with requests for highly customer-specific products that come in numerous variants but small numbers of units per variant. Therefore, their manufacturing processes need to be ... -
Visual Analysis of Degree-of-Interest Functions to Support Selection Strategies for Instance Labeling
(The Eurographics Association, 2019)Manually labeling data sets is a time-consuming and expensive task that can be accelerated by interactive machine learning and visual analytics approaches. At the core of these approaches are strategies for the selection ... -
Visual Analysis of Expert Systems for Smart Grid Monitoring
(The Eurographics Association, 2013)This application paper introduces the combination of an expert system with a visualization system, specifically designed for SmartGrid control rooms. It supports operators in the efficient monitoring of electric grids with ... -
Visual Analysis of Explicit Opinion and News Bias in German Soccer Articles
(The Eurographics Association, 2012)Most state-of-the-art opinion and sentiment analysis techniques were developed for customer feedback data or reviews. Applying them to another domain is often not possible because the algorithms are based on the assumption ... -
Visual Analysis of Geo-spatial Data in 3D Terrain Environments using Focus+Context
(The Eurographics Association, 2017)Visual analysis of geo-spatial data represented within a three-dimensional frame of reference is a challenging task. Focus+ Context is a common concept that aids this process. This paper addresses the question, how ... -
Visual Analysis of Optical Coherence Tomography Data in Ophthalmology
(The Eurographics Association, 2017)Optical coherence tomography (OCT) enables noninvasive high-resolution 3D imaging of the human retina and thus, plays a fundamental role in detecting a wide range of ocular diseases. Despite OCT's diagnostic value, managing ... -
Visual Analysis of Public Transport Vehicle Movement
(The Eurographics Association, 2012)Public transport vehicles record detailed operational logs. In major networks, this quickly amounts to massive datasets. Traditionally, these are analysed only using statistical tools, yet they show great potential for the ... -
Visual Analysis of Relations in Attributed Time-Series Data
(The Eurographics Association, 2015)In this paper, we present visual-interactive techniques for revealing relations between two co-existing multivariate feature spaces. Such data is generated, for example, by sensor networks characterized by a set of ... -
Visual Analysis of Tracts of Homozygosity in Human Genome
(The Eurographics Association, 2013)We propose a new visual analytics system designed for genetic researchers to study genome-wide homozygosity regions. Finding significant tracts of homozygosity (TOH) using single nucleotide polymorphisms (SNPs) from a ... -
Visual Analysis of User Behaviour in Pay-Per-Bid Auctions
(The Eurographics Association, 2011)In pay-per-bid auctions, placing a bid costs a fee, and only raises the price of the item by a small increment. At the conclusion of the auction, the last bidder wins, and the price paid by the winning bidder is subsidised ... -
Visual Analytics and Uncertainty: Its Not About the Data
(The Eurographics Association, 2015)Uncertainty visualization research has a long history, with contributions from scientific, information, geo-graphic and other visualization perspectives as well as from cognitive and HCI perspectives. But we still do not ... -
A Visual Analytics Approach for User Behaviour Understanding through Action Sequence Analysis
(The Eurographics Association, 2017)Analysis of action sequence data provides new opportunities to understand and model user behaviour. Such data are often in the form of timestamped and labelled series of atomic user actions. Cyber security is one of the ... -
A Visual Analytics Approach to Segmenting and Labeling Multivariate Time Series Data
(The Eurographics Association, 2014)Many natural and industrial processes such as oil well construction are composed of a sequence of recurring activities. Such processes can often be monitored via multiple sensors that record physical measurements over time. ... -
A Visual Analytics Field Experiment to Evaluate Alternative Visualizations for Cyber Security Applications
(The Eurographics Association, 2014)The analysis and exploration of emerging threats in the Internet is important to better understand the behaviour of attackers and develop new methods to enhance cyber security. Fully automated algorithms alone are often ...
