Comment: update description of included dictionaries and models

...

These instructions are for end users. With these instructions you can install Apache cTAKES, configure it, and use it to process text (typically text associated with a medical record). If you were planning to expand, change, or modify the code within cTAKES, refer to the cTAKES 3.0 Developer Guide.

These instructions will cover installation and a test of the main product including trained models for sentence detection and tagging parts of speech, dictionaries from a subset of the UMLS, a very small subset of the full LVG resource, etc. Optional components are described in the Component Use Guide.

Once you have finished installing cTAKES and its separately-bundled resources, you will be able to see what cTAKES is capable of. Further exploitation of the software's ability may require following a few additional steps involving what dictionaries are being used. The last section on this page covers these next steps .

Prerequisites

Step

Example

1. Make sure you have Java 1.6 or higher. Most systems come with Java already installed.

Run this command to check your version.

Windows and Linux:

Code Block
languagenone
java -version

Windows:

Code Block
languagenone
C:\>java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)


Linux:

Code Block
languagenone
tbleeker@system:/$ java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.1) (6b22-1.10.1-0ubuntu1)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

...

Also, before you go on to process text in production you will need want to consider dictionaries and models. cTAKES does not distribute from Apache a complete dictionary capable of annotating production data. The models provided (within the separate resources download) have been trained on data that may not match your data well enough to be effective. In most some cases , you will need might want to modify the dictionaries and train models on your own data to be effective.
