Data preprocessing

Preprocessing steps to obtain query-specific graph $\widetilde{G}$

Step 0: Download Freebase

wget https://download.microsoft.com/download/A/E/4/AE428B7A-9EF9-446C-85CF-D8ED0C9B1F26/FastRDFStore-data.zip --no-check-certificate

unzip FastRDFStore-data.zip.

Step 1: Filter Freebase

python get_id2name.py
python manual_filter_rel.py
python filter_rel.py

Step 2: Prepare basic elements (entities, answers, topic entities) for dataset

python preprocess_step0.py 

Step 3: Use PPR algorithm to get $\widetilde{G}$ for each query

python PPRmultithread.py
