Prob-CBR

Code for the EMNLP-Findings paper -- Probabilistic Case-based Reasoning for Open-World Knowledge Graph Completion

Download data

Download the experiment prob-cbr-data from here, untar it in the root directory of the project. The compressed size is ~17M and uncompressed size is ~91M.

wget http://iesl.cs.umass.edu/downloads/cbr-akbc-data/prob-cbr-data.tar.gz && tar xzvf prob-cbr-data.tar.gz

NOTE: data_dir expects the path to the top level directory prob-cbr-data

KBC streaming experiments

Prob-CBR-Stream

To reproduce results from the paper, run the following:

# WN18RR

python prob_cbr/prob_cbr_streaming.py -dataset WN18RR \
  --data_dir ../prob-cbr-data/ \
  --expt_dir ../prob-cbr-expts/ \
  --test --test_file_name testI.txt \
  --max_num_programs 200 --k_adj 50 --cluster_threshold 0.7 \
  --stream_init_proportion 0.5 --n_stream_updates 10 \
  --name_of_run online_stream_wn18rr_test
# FB122

python prob_cbr/prob_cbr_streaming.py -dataset FB122 \
  --data_dir ../prob-cbr-data/ \
  --expt_dir ../prob-cbr-expts/ \
  --test --test_file_name testI.txt \
  --max_num_programs 80 --k_adj 10 --cluster_threshold 0.6 \
  --stream_init_proportion 0.5 --n_stream_updates 10 \
  --name_of_run online_stream_fb122_test

To speed up stream running time, you can use a preprocessing step

# Preprocessing
# PROC_NUM can be 
# -1 (to process all steps) 
# OR
# an int in range [0, n_stream_updates] to preprocess a certain step

python prob_cbr/prob_cbr_streaming.py -dataset FB122 \
  --data_dir ../prob-cbr-data/ \
  --expt_dir ../prob-cbr-expts/ \
  --test --test_file_name testI.txt \
  --max_num_programs 80 --k_adj 10 --cluster_threshold 0.6 \
  --stream_init_proportion 0.5 --n_stream_updates 10 \
  --name_of_run online_stream_fb122_test \
  --just_preprocess --process_num $PROC_NUM
# Actual run

python prob_cbr/prob_cbr_streaming.py -dataset FB122 \
  --data_dir ../prob-cbr-data/ \
  --expt_dir ../prob-cbr-expts/ \
  --test --test_file_name testI.txt \
  --max_num_programs 80 --k_adj 10 --cluster_threshold 0.6 \
  --stream_init_proportion 0.5 --n_stream_updates 10 \
