Extraction Browser
From Knowitall
(Re)starting the Extraction Browser Web Demo on Reliable
- Log in to reliable as knowall
- check that a screen called 'extractionBrowser' is not already running. If it is, switch to it (using command 'screen -r extractionBrowser') and skip the next step.
- run the command 'screen -S extractionBrowser'.
- run the command 'java -jar ~/web/jetty/jetty-distribution-8.0.4.v20111024/webapps/extractionbrowser-1.0.0-jetty-console.war --port 8088'. This will start the extraction browser servlet listening on port 8088 (openie.cs <==> reliable.cs:8088)
- If everything works normally, stdout should display a small amount of output ending with the text "STARTING", without any error messages or stack traces. At this point, the Servlet is ready to serve demo requests.
- Verify that you can see the demo at openie.cs.washington.edu and optionally (if troubleshooting) reliable.cs.washington.edu:8088
- Detach the screen session by pressing 'Control-a d'.
Note: Extraction Browser should automatically restart itself under knowall on the machine reliable in the event of a reboot, due to the following crontab entries: (current as of 12/23/2011)
- @reboot screen -dmS extractionBrowser java -jar ~/web/jetty/jetty-distribution-8.0.4.v20111024/webapps/extractionbrowser-1.0.0-jetty-console.war --port 8088
- @reboot /home/knowall/local/opt/memcached/bin/memcached -d -m 2048 -l `hostname --ip` -p 11211
Bug List
- Search for predicate:"is located in" yields a null error.
- Search for argument1:"United States" overconstrains the results.
