Steps to install the smlar extension into Postgres

Published on 7/28/2014

The smlar extension lets you do TF-IDF and cosine similarity calculations in Postgres.

If you figure out how to compile these on Windows (64-bit), please let me know.

In your shell:

cd /usr/local/src

git clone git://sigaev.ru/smlar.git

cd smlar

export USE_PGXS=1

make

make install

In Postgres:

create extension smlar;

Test it out:

select smlar( '{a,b}'::text[], '{c,a}'::text[] );

Output

	smlar real
1	0.5
