== Short description ==
[[Groth%2C_Dennis_P.|Dennis P. Groth]] claims that there is not only a wealth of information within common visualization systems, but also within the user's interaction with the actual system. He states that while it is no doubt important for a single user to gain knowledge und to come to certain conclusions while using a visualization system, it is equally important that other users are can easily understand and reproduce the results. Therefore he suggests to employ a system that actually visualizes the user's interactions with the existing visualization system. 
Exploring these interactions utilizes various visualization techniques for knowledge discovery in order to unveil implicit phonemes. As most exploration settings take place in a highly diverse environment employing multiple activities, individuals and locations tracking and processing is quite challenging.
Commonly used interactive visualizations are not only limited to a single application in question but also disseminating findings for further exploration are not provided adequately.
 
 
The presented framework employs a fine-grained provenance tracking.
{{Quotation|The visualization of hierarchical information structures is an important topic in the visualization community. Most of the work concentrated on the challenge to display large hierarchies in a comprehensible form.| [Groth, D.P., 2007]}}
 
Generally this framework is based on three building blocks:
*Session (the overall block containing multiple activities)
*Activity (represents a single application (e.g. visualization system, browser, etc.))
*Action (User actions like zooming, rotating an image or even browsing through the web)
 
[[Image:session_activity_action.jpg|300px]] 
''Schematic view of building blocks''
 
 
As multiple activities arise within a session a logical linkage evolves. In general, three types of linkage are given:
*Serial events representing a temporal order
*Branching relations when actions are considered as logical states
*Association when action happens across activities
 
From the arithmetic perspective this framework can be described as a directed graph.
Nodes
describes state of the system, whereby branches occur when the user reverts to an earlier state of an activity. Hence the user is able to browse through the exploration history afterwards.
Edges
transitions among the states. the latest implementation of proposed frameworks supports colored edges indicating different activities.

{{Quotation|Annotation plays a critical role in the exploration process, in that it provides a mechanism for users to capture their observations of what they are seeing in the visualization.| [Groth, D.P., 2007]}}
 
Therefore a minor tagging theme is implemented whether tagging is manually or automatically associated with a given action. Hence another type of clustering actions and alternate graph representations are provided.

However, this project is still in construction as further extensions are progressed. So an API is going to be provided in order to link applications in question into the provenance tracking system. Furthermore more explorations on automated tagging scheme are underway.

Dennis P. Groth is a researcher in the field of information visualization and an associate professor at the Indiana University. He also gained substantial industry experience, as manager and consultant in various software projects and firms prior to his academic career.

== Biography ==

Groth received his B.S. degree in Computer Science at the Loyola University of Chicago in 1983. He subsequently started working in the software industry before he decided to enter graduate school. His major industry occupations are outlined in the following:
 
*1983 - 1984: Consultant, Andrea Data Systems
*1984 - 1990: Project Manager, Spectrum Healthcare Solutions
*1990 - 1994: Manager, Systems Development, Moore Advanced Services
*1994 - 1995: Director, Crawford Consulting, Inc.
*1995 - 1996: Independent Software Development Consultant
 
In May 2002 he received his Ph.D. in Computer Science at the Indiana University, where he has since been engaged in various tasks:

*2002 - 2008: Assistant Professor, School of Informatics
*2006 - 2008: Director, Undergraduate Studies, Department of Informatics
*2008 - present: Associate Professor, School of Informatics, Adjunct Associate Professor, Department of Computer Science
*2008 - present: Associate Dean for Undergraduate Studies, School of Informatics

== Research Interests ==

Groth‘s main research interest is in database visualization, data mining and human-computer interaction. He especially focuses on exploring ways in which visualizations can be manipulated in the same fashion as the data that the visualizations are generated from. In developing such techniques Groth sees an opportunity to facilitate knowledge gain for the user.
