Analytic representations: the design of tools to create and exploit them
Gregory Dyke
Carnegie Mellon University

My dissertation focussed on computer support for "human analysis" (as opposed to the semi-automated or computer assisted analysis). As a result I created a tool called Tatiana ( ) which has interesting properties for researchers who collect and analyse various kinds of process data (videos, computer logs, transcripts, etc.). Tatiana is built on a framework for constructing and managing analytic representations using four quasi-orthogonal operation types: transformation, enrichment, visualisation and synchronisation.

This talk will describe Tatiana and the underlying framework:
- What Tatiana can currently do and what features are planned for the future.
- How Tatiana may be able to help solve research problems when analyzing videos, computer logs, transcripts, etc.
- Situations in which it might be beneficial to extend Tatiana, rather than constructing new software from scratch.

About Gregory Dyke: I am interested in the creation of tools to help humans analyse data of computer mediated collaboration (and learning). My PhD resulted in the creation of Tatiana (Trace Analysis Tool for Interaction ANAlysts), a flexible, extensible tool particularly well suited for the analysis of small group face to face and computer mediated interaction. My current work involves examining and assisting the discovery of how interaction unfolds over time.
