This section describes the steps to download and install a full version of the NCI Thesaurus for the LexEVS Service.

Note
titleNote

The NCI Thesaurus has grown large enough that it can no longer be loaded on many typical desktop machines. We recommend a 64-bit operating system running on a multiprocessor computer with a minimum of 4g of memory. Server class Linux machines are the typical target for these loads. The time to load NCI Thesaurus will vary depending on machine, memory, and disk speed. Expect a couple of hours for a higher end machine.

Step

Using a web or ftp client go to the URL: ftp://ftp1.nci.nih.gov/pub/cacore/EVS/ screenshot of FTP directory

2

Select the version of NCI Thesaurus OWL you wish to download. Save the file to a directory on your machine.

3

Extract the OWL file from the zip download and save in a directory on your machine. This directory will be referred to as NCI_THESAURUS_DIRECTORY

Using the LexEVS utilities load the NCI Thesaurus:

Code Block

This section describes the steps to download and install a full version of the NCI Metathesaurus for the LexEVS Service.

Note
titleNote

NCI Metathesaurus contains many individual vocabularies some of which are large vocabularies in and of themselves. It requires many hours to load and index. It can require 36 hours on a multiprocessor machine with 6g plus memory. The total time to load NCI MetaThesaurus will vary depending on machine, memory, and disk speed. Because this loader uses a batch loading strategy it is less dependent on memory, but some users will see 3 or 4 day load times with average multiprocessor processing power.
