EMOTION AND SENTIMENT ANALYSIS IN TEXT

Research addressed RBC need for tools to help identify the emotional response of clients regarding bank services in order to improve their customer services. As of date, they are interested in a software solution to help them visualize networks of subsidiaries, in order to analyse money flow between different counterparts (borrowers and lenders)

 

GOALS & MISSION:
_________________________________________________________________________

To develop visualization analysis tools which can be used (internally) by RBC to better understand existing data.

THE CARE AND COGNITION MONITOR

Visual analytic tools, combined with social networks and mobile platforms, make it possible to create multi-dimensional, holistic pictures of people’s health care and condition and expand the scope of information addressed in medical records. The Care and Condition Monitor (CCM) is a tablet-based, networked visual analytics tool for collecting, structuring and analyzing informal and qualitative healthcare data and visualizing it in a circular format. It illustrates how social communication within teams of caregivers enables capturing of longitudinal informal data that can (a) result in rich and meaningful information visualizations, (b) improve comprehension of healthcare data and changes in condition over time, and (c) support medical decision making.

THE STACKED STACKED BAR GRAPH

Stacked-stacked bar graph is the working title of a visualization that builds on the strengths of a stacked bar graph. Where a stacked bar graph allows for a visual comparison of the parts to the whole, our proposed visualization further divides the parts to allow for additional points of comparison.

THE INFINITE CANVAS

The Infinite Canvas is a tablet display for news search results display that takes advantage of spatial relationships to understand connections between articles.  The articles are sorted by relevance along the vertical direction, and by date along the x direction.

A TANGIBLE USER INTERFACE FOR DATA QUERY

We are creating a Tangible User Interface (TUI) designed to interactively query a database.  While much work has been done on TUI, showing that they encourage collaboration and positively enhance user experience, few tangible systems have been designed specifically for data analysis tasks.  Our system combines a tabletop (non-digital) graspable user interface with a two-dimensional screen display; the user interrogates the data by placing tokens on or off the tabletop and the screen displays the results of the user’s query.  The objects are tagged using fiducial markers, which are identified with open-source ReacTIVision computer vision software, and the visualization code is written in Processing.  We use radio station listenership demographic data for our current prototype, but the system can be used to query any type of database.

Below is a schematic of our tangible data query system.  Users create queries by placing objects onto a table, which has a camera placed discretely below it; the results of the query are displayed onto an overhead screen placed at one end of the table.  A video of the interaction can be viewed here: https://www.youtube.com/watch?v=XfTvTsqG5ZI
