So, if I want to see all redirects using custom build index file (that
includes complete redirects_en.nt dump), I need to do the following steps
1. Change the config/minincoming.properties min-score=0 (I want all the
redirects to come in the result)
2. Create incoming_links.txt again using the entityrankings.sh link
provided by Rupert in previous mail.
2. Regenrate the index file with redirects_en.nt included (and using
incoming_links file created in step 2)
And then use that index file and run the following query :
{
"selected": [
"rdfs:label" ],
"offset": "0",
"limit": "5",
"constraints": [{
"type": "reference",
"field": "http://dbpedia.org/ontology/wikiPageRedirects";,
"value": "http://dbpedia.org/resource/Athletic_shoe";
}]
}
Are above steps complete or I have missed anything missing?
Thanks and Regards,
Manish
