Question answering over Freebase (single-relation).

This is the source code for Question Answering over Freebase via Attentive RNN with Similarity Matrix based CNN.

• Python 3.5
• PyTorch 0.2.0
• NLTK
• NLTK data (tokenizers, stopwords list)
• Virtuoso

After install Virtuoso, you should modify config file at freebase_data/dump_virtuoso_data/virtuoso.ini (or you could copy your virtuoso.ini file to this directory)

1. You have to change the variables such as NumberOfBuffers and MaxDirtyBuffers depending on your RAM. For other variables you can follow the official documents.
2. Add the absolute path of XXX/freebase_data/dump_virtuoso_data/ to DirsAllowed.

This may need to be under the root user.

Run the setup script. This takes a long time. It fetches datasets, does some preprocesses, and dumps Freebase triples into Virtuoso.
