Overview

A Critical Assessment of State-of-the-Art in Entity Alignment

This repository contains the source code for the paper

A Critical Assessment of State-of-the-Art in Entity Alignment
Max Berrendorf, Ludwig Wacker, and Evgeniy Faerman
https://arxiv.org/abs/2010.16314

Installation

Setup and activate virtual environment:

python3.8 -m venv ./venv
source ./venv/bin/activate

Install requirements (in this virtual environment):

pip install -U pip
pip install -U -r requirements.txt

In order to run the DGMC scripts, you additionally need to setup its requirements as described in the corresponding GitHub repository's README. We do not include them into requirements.txt, since their installation is a bit more involved, including non-Python dependencies.

Preparation

MLFlow

In order to track results to a MLFlow server, start it first by running

mlflow server

Note: When storing the result for many configurations, we recommend to setup a database backend following the instructions. For the following examples, we assume that the server is running at

TRACKING_URI=http://localhost:5000

OpenEA RDGCN embeddings

Please download the RDGCN embeddings extracted with the OpenEA codebase from here and place them in ~/.kgm/openea_rdgcn_embeddings. They require around 160MiB storage.

BERT initialization

To generate data for the BERT-based initialization, run

(venv) PYTHONPATH=./src python3 executables/prepare_bert.py

We also provide preprocessed files at this url. If you prefer to use those, please download and place them in ~/.kgm/bert_prepared. They require around 6.1GiB storage.

Experiments

For all experiments the results are logged to the running MLFlow instance.

Note: The hyperparameter searches takes a significant amount of time (~multiple days), and requires access to GPU(s). You can abort the script at any time, and inspect the current results via the web interface of MLFlow.

Zero-Shot

For the zero-shot evaluation run

(venv) PYTHONPATH=./src python3 executables/zero_shot.py --tracking_uri=${TRACKING_URI}

GCN-Align

To run the hyperparameter search run

(venv) PYTHONPATH=./src python3 executables/tune_gcn_align.py --tracking_uri=${TRACKING_URI}

RDGCN

To run the hyperparameter search run

(venv) PYTHONPATH=./src python3 executables/tune_rdgcn.py --tracking_uri=${TRACKING_URI}

DGMC

To run the hyperparameter search run

(venv) PYTHONPATH=./src python3 executables/tune_dgmc.py  --tracking_uri=${TRACKING_URI}

Evaluation

To summarize the dataset statistics run

(venv) PYTHONPATH=./src python3 executables/summarize.py --target datasets --force

To summarize all experiments run

(venv) PYTHONPATH=./src python3 executables/summarize.py --target results --tracking_uri=${TRACKING_URI} --force

To generate the ablation study table run

(venv) PYTHONPATH=./src python3 executables/summarize.py --target ablation --tracking_uri=${TRACKING_URI} --force
