What To Know before You Begin

How to Start a New OpenCyc image

A “Cyc Image” is simply a version of Cyc running on an individual computer. Before you can use the browser in order to look at the KB, you must get a new image running on your computer. The steps for doing so differ by platform:

  • NT image:
    • (not yet available)
  • C image for Unix (LINUX):
    • Connect to the directory with the Cyc executable:cd OpenCyc-x.x.x/scripts/linux [where x.x.x = current version]
    • Launch the Cyc server:./run-cyc.sh

How to Get to the KB Browser (and other places)

To get to the KB browser, first start up Netscape Navigator. Then, you can access the following useful URLs for navigating around:

The OpenCyc KB Browser (http://<hostname>/cgi-bin/cyccgi/cg?cb-start): the main tool for accessing the Cyc Knowledge Base (KB). If you’ve just started up your image for the first time, this should probably be the URL to go to.

The Cyc Navigator (http://<hostname>/cgi-bin/cyccgi/cg?cyc-navigator): a suite of tools for the Cyc System.

The Cyc Documentation Table of Contents (http://<hostname>/cycdoc/toc.html): documentation for anything and everything in the Cyc System.

Note: With all of these URLs, please replace the string “<hostname>” with the name of your webserver. If your webserver is running under NT, you’ll need to replace the “cg?” with “cg.exe?”.
