Hi All,
Greeting for the day..
I want to extract infobox properties and abstract from
(pages-articles.xml.bz2).I am able to download this file using command
"../run download config=download.de.properties"
here I have configured file download.de.properties.file to download only
german page-article file.
Now when i am trying to extract information out from it using "../run
extraction extraction.de.property" it is giving me below error. In
*extraction.de.property
*I have mentioned dir properly , the same which I have mentioned in
download.de.properties file.
Please let me know what wrong is going on?Is there any change need to be
done in pom.xml of cump dir.
