LightNE

Code for SIGMOD 2021 submission LightNE: A Lightweight Graph Processing System for Network Embedding.

LightNE algorithm is in the LightNE directory.

Dependencies Installation

Install g++

The code is compiled and run with g++ 6.5.0 and 5.4.0 (any supporting c++17 should work in theory).

Install Boost

In the spectral propagation step, we need modified Bessel functions of the first kind. Boost provides such functions. So we need to install Boost.

sudo apt-get install libboost-dev

Install Intel MKL

There are two ways to install Intel MKL.

  • The first way is to install with Anaconda (recomended)
conda create -n lightne python=3.7 # first create a new python env
conda activate lightne # activate the new created env
conda install mkl -c intel --no-update-deps
conda install mkl-devel
  • The second way is to download directly from Intel. Please follow
https://software.intel.com/en-us/mkl/choose-download/linux

You will download something named parallel_studio_xe_2019_update4_cluster_edition_online.tgz and the installation script will install intel mkl (by default) at /opt/intel.

Install other necessary dependencies

The preprocessing script (which translate .mat or .edgelist graph to AdjacencyGraph format) and the evaluation script requires the following python libs:

pip install sklearn pandas scipy

Compile

To compile Ligne, you need to edit Makefile a little, indicating the directories of your Intel MKL.

If you install intel mkl directly, then you need to set something like:

INCLUDE_DIRS = -I../ -I/opt/intel/mkl/include
LINK_DIRS = -L"/opt/intel/mkl/lib/intel64"

Otherwise, if install with Anaconda, then you need to set something like:

INCLUDE_DIRS = -I../ -I"/home/XXX/anaconda3/envs/lightne/include"
LINK_DIRS = -L"/home/XXX/anaconda3/envs/lightne/lib"

Then run make to compile.

To clean the compiled file, run make clean.

Run

BlogCatalog

I have uploaded BlogCatalog dataset and this git repo (at data_bin/blogcatalog.mat).

If your intel mkl is installed directly, you need something like:

export LD_LIBRARY_PATH=/opt/intel/mkl/lib/intel64

If installed with Anaconda, then you need something like:

export LD_LIBRARY_PATH=/home/XXX/anaconda3/envs/lightne/lib

Then you can run blog_lightne.sh. The running log is stored at blog_lightne.log

Datasets from NetSMF paper

Download and unzip datasets used in NetSMF paper

cd data_bin
wget https://sampledbsql1backup.blob.core.windows.net/www19netsmf/datasets.zip
unzip datasets.zip

unzip will give you the following files:

Archive:  datasets.zip
  inflating: blogcatalog.mat
  inflating: flickr.mat
  inflating: mag.edge
  inflating: mag.label.npz
  inflating: MicrosoftResearchDataLicenseAgreement.pdf
  inflating: ppi.mat
  inflating: Readme.txt
  inflating: youtube.mat

Besides BlogCatalog, You can run youtube_lightne.sh, mag_lightne.sh for each dataset.
