In this repo, we present the application of CASE-BASED REASONING FOR DRUG REPURPOSING

Code for the AKBC'20 paper -- A Simple Approach to Case-Based Reasoning in Knowledge Bases

Setup

Download the experiment data from here, untar it in the root directory of the project.

The compressed size is ~401M and uncompressed size is ~716M.

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

Set the pythonpath in root directory of the project

export PYTHONPATH=`pwd`

To reproduce results from the paper, run the following:

WN18RR
python code/cbr.py --dataset_name WN18RR --test --k_adj 5 --max_num_programs 25

To run for a new dataset, first a random subgraph around each entity needs to be collected and written to disk.

In our experiments, we just collect 1000 random paths aorund each entity by doing DFS.

python code/data/get_paths.py --dataset_name <insert_dataset_name> --num_paths_to_collect 1000 --data_dir cbr_akbc_data
