In the 21st Meetup of KW Intersections, we will have two talks, the first will be presented by Olga Buchel and is entitled ‘Towards knowledge discovery with visualization techniques’. The second talk, “just enough parsing and grammar for a DSL, when a (single) regular expression won’t quite cut it by”will be presented by Pieter Geerkens.

Towards knowledge discovery with visualization techniques by Olga Buchel, PhD

Information visualization and visual analytics are relatively new disciplines that are concerned with

the design of visual representations and interactions for improving knowledge discovery, decision making, and problem solving. In this presentation, I will demonstrate how visualization techniques can improve the analysis

of complex geo-social datasets (i.e., datasets that have references to geographic locations and relationships among geospatial entities). These techniques may lead to new insights which are hard to detect with traditional network and geospatial visualization tools.

Olga Buchel is an interdisciplinary researcher specializing in information visualization, geovisualization, and visual analytics. She has a PhD in Library and Information Science from Western University. Her most recent publications are about interactive exploratory visualizations in public health and business. She presented her research at a number of international conferences, including GEOMED, iConference, ASIST, the workshop on Provenance of Sensemaking at IEEE VIS, and other conferences. She currently works at siTechnologyGroup, Inc., where she develops health apps and visualizations from health data. She also teaches interactive design at Fanshawe College in London, ON.

just enough parsing and grammar for a DSL, when a (single) regular expression won’t quite cut it by Pieter Geerkens

The first part of the talk is a simple Recursive Descent structure using Regex’s for validation of individual lines or partial lines, using examples from a game project. Next we build a more complex grammar using Irony.NET ( http://irony.codeplex.com/ ), using a QABC Music Notation parser Pieter wrote a few years ago as an example.
