Instructions to create triples file and load in blazegraph format

Server files including triples can be created by following the instructions below. We use blazegraph to host the server, however any other triple store should work too.

Create triples file

Get wikidata_proc_json_2 from CSQA Dataset

python json_to_triples.py

Load triples to blazegraph

bash load_ttl.sh

This will produce wikidata.jnl

Start server

• copy properties filem wikidata.jnl and wd_prefix.ttl into server_files
• Get the blazegraph.jar via Blazegraph

export PATH=$PATH:$JAVA_HOME
cd path_to/server_files
/usr/java/java-11.0.5/bin/java -server -Xmx150g -XX:+UseG1GC -Dcom.bigdata.rdf.sail.sparql.PrefixDeclProcessor.additionalDeclsFile=wd_prefix.ttl -jar blazegraph.jar
