DBpedia is distributed, among other formats, as a set of .ttl.bz2 files. We use a selection of these .ttl files, as defined in data/config/dbpedia2mongo.config.json. You can download these files from DBpedia Website. We provide a minimal sample from DBpedia under data/dbpedia-2015-10-sample, which can be used for testing Nordlys on a local machine. Check data/raw-data/dbpedia-2015-10 for detailed information.
The Freebase Annotations of the ClueWeb Corpora (FACC) is used for building entity surface form dictionary. You can download the collection from its main Website. and further process it using our scripts. Alternatively, you can download the preprocessed data from our server. Check the README file under data/raw-data/facc for detailed information.
Word2Vec vectors (300D) trained on Google News corpus, which canbe dowloaded from the its Website. Check the README file under data/raw-data/word2vec for detailed information.
