Building word2vec

1. Install standard utilities, packages and platform specific dependencies

• RHEL (6.9, 7.3, 7.4, 7.5)

   sudo yum install -y git gcc make wget tar unzip

• SLES (11 SP4, 12 SP2, 12 SP3)

• Ubuntu (16.04, 17.10, 18.04)

   sudo apt-get update
   sudo apt-get install -y git gcc make wget tar unzip

2. Create a working directory and download word2vec source code

    mkdir /<source_root>/
    cd /<source_root>/
    wget https://storage.googleapis.com/google-code-archive-source/v2/code.google.com/word2vec/source-archive.zip
    unzip source-archive.zip
   

3. Build word2vec

    cd word2vec/trunk
    make CFLAGS="-lm -pthread -O3 -Wall -funroll-loops"
   

4. Set environment variables

    export PATH=$PATH:/<source_root>/word2vec/trunk
   

5. Test word2vec using demo scripts

    ./demo-word.sh
    ./demo-phrases.sh
   

   Note: Enter test corpus as input and get word vectors as output, e.g. Input=france
