2. CmapTools: Integrating knowledge and information visualization

The CMEX Mars knowledge model consists of over 100 concept maps that are used as a means to browse and search through over 600 MBs of resources of all types.

The “Mars” concept map in the figure is the top-level map, the entry point to this knowledge model. Some concepts in the “Mars” concept map have small icons underneath them. These icons indicate that there are other resources (e.g., images, text, videos, Web pages, other concept maps) that contain additional information, refer to, or further explain that particular concept. By clicking on the “concept map” icon underneath a concept, a list of available concept maps is displayed, which the user can select and open.

3. Searching and mining the web from concept maps

Utilizing context information provided by a concept map to (1) provide more complete queries to the search engines, and (2) enhance the ranking of the results provided by the engines.
