The way I see it, you have two options.

1. You could either attempt to implement an approach like this one exactly, or fork the repo behind this approach (or another like it) and extend/fix it to fit your purposes.

2. Do it yourself, from scratch. Here's the general approach:

Parse your dbpedia dataset into a format suitable for neo4j's insertion methods. There are libraries that exist like openRDF that exist to process data. Unless you plan to take the time to research which would suit your needs best, the existing solution I linked above already implements this library.

Then insert the formatted data into your neo4j db. One method to accomplish this is through neo4j's Batch Insertion component. Note this facility, as they state, is intended for initial imports (as it's not thread safe and is non-transactional, in other words, not ACID-compliant). So this really depends on your use case.

My 2 cents is that you use something already out there unless this functionality is the core of what you're developing. As it's something that will be a pain to build, and even more a pain to build something that runs efficiently.
