Visualizing Concept Based Text Searches Zack Jacobson (zack.jacobson@cac.gc.ca) Ben Houston (ben.houston@cac.gc.ca)

Concept Based Queries User gives a query as keywords or in the form of a question. Search engine (Inquizit) identifies concepts related to the query. For each concept relevant portions of documents are identified.

An Example... 1) The Query: 2) The Concepts: What color is the sky? 2) The Concepts: Color, Hue, Sky, Atmosphere 3) The Extracts and Documents: “the sky is blue.” Questions Children Ask “the bluish hue results from the refraction of light in the upper atmosphere” Introduction to Physics

Visualizing Relations Concepts. Extracts -- relates the Concepts to the Documents. Documents. sky blue Intro to Physics Questions Children Ask
