UMLS suggestions

A compact search engine to suggest (preferred) UMLS terms.

Installation

This is a small nodeJS and elasticsearch project.

• Download UMLS : http://www.nlm.nih.gov/research/umls/
• Run the load scripts to get the UMLS records in database
• Add index keys to the mrconso and mrsty database (on CUI)
  • ALTER TABLE mrconso ADD INDEX(CUI);
  • ALTER TABLE mrsty ADD INDEX(CUI);
• npm install to get the node modules.
• cp json/example_config.json json/config.json to create a local config file. Edit this to the correct database settings.

Usage

If you have elasticsearch, node and npm installed you can use npm start (assuming elasticsearch runs on localhost:9200). There is now an app on localhost:9000. Since it is only a prototype there are no security settings. To setup your "database" goto: localhost:9000/install. This will create an empty index for new records.

After installing you can insert UMLS records. Enter the CUI + preferred title and alternatives. The alternatives can contain multiple entries seperated by |.
