This section describes the steps to download and install a full version of the NCI Thesaurus for the LexEVS Service.
The NCI Thesaurus differs from other OWL formatted resources and, as a result administrators usually take advantage of some of the custom loading resources available in LexEVS. While users can download the Thesaurus.owl file from NCI and load it into LexEVS without it failing, many users will want to customize it with xml formatted manifest and preferences files.

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. |
