Exploratory Visualization Involving Incremental, Approximate Database Queries and Uncertainty

Danyel Fisher, Steven M. Drucker, A. Christian Knig
2012 IEEE Computer Graphics and Applications  
In exploratory systems, users will try riskier queries and can modify their subsequent queries with the previous ones in mind.  ...  The queries that users issue in exploratory visualization differ fundamentally from those arising in noninteractive batch systems.  ...  Online query processing is meant to help enable exploratory data visualization on very large datasets.  ...

Trust, but Verify: Optimistic Visualizations of Approximate Queries for Exploring Big Data

Dominik Moritz, Danyel Fisher, Bolin Ding, Chi Wang
2017 Proceedings of the 2017 CHI Conference on Human Factors in Computing Systems - CHI '17  
Analysts need interactive speed for exploratory analysis, but big data systems are often slow.  ...  With sampling, data systems can produce approximate answers fast enough for exploratory visualization, at the cost of accuracy and trust.  ...  "I'm doing exploratory data analysis and I don't need full accuracy."  ...

Concept-Driven Visual Analytics

In Kwon Choi, Taylor Childers, Nirmal Kumar Raveendranath, Swati Mishra, Kyle Harris, Khairi Reda
2019 Proceedings of the 2019 CHI Conference on Human Factors in Computing Systems - CHI '19  
Visualization tools facilitate exploratory data analysis, but fall short at supporting hypothesis-based reasoning.  ...  We conducted an exploratory study to investigate how visualizations might support a concept-driven analysis style, where users can optionally share their hypotheses and conceptual models in natural language  ...  For instance, when querying lung cancer mortality in Minneapolis, P7 simply noted: "I don't know what to expect".  ...

Kumaripaba Athukorala, Dorota Głowacka, Giulio Jacucci, Antti Oulasvirta, Jilles Vreeken
2015 Journal of the Association for Information Science and Technology  
One reason is the lack of empirical knowledge on how to distinguish exploratory and lookup search behaviors in IR systems.  ...  Exploratory search is an increasingly important activity yet challenging for users.  ...  Antti Salovaara for reading the draft and providing insightful comments, and Kalle Ilves and Imtiaj Ahmed for helping to set up the user study.  ...

2014 Proceedings of the 32nd annual ACM conference on Human factors in computing systems - CHI '14  
A preliminary user study shows promising results: that users have a justified confidence in their answers with our system.  ...  Uncertain visualizations are good at representing data distributions emerging from samples, but are more limited in allowing users to carry out decision tasks.  ...  In sample-based analyses, we carry out approximate versions of these queries: we estimate the expected average, sum, or count of a dataset based on the sample, and infer a distribution on this expected  ...

GeoSneakPique: Visual Autocompletion for Geospatial Queries [article]

Vidya Setlur, Sarah Battersby, Tracy Wong
2021 arXiv   pre-print
GeoSneakPique presents a novel method for using a mapping widget to support the NL query process, allowing users to specify location via direct manipulation with data-driven guidance on spatial distributions  ...  While location is at the heart of many data questions, geographic location can be difficult to specify in natural language (NL) queries.  ...  The named region is saved by the system and can be referenced in future queries (e.g. "what are the recent ones in the midwest?"). The main map is updated to show the result from the query.  ...
