Hello everyone,
Can anyone point me to an exhaustive set of documentation regarding cTakes?
* Not really. The wiki that you found is the most that there is.
* Most information is scattered across emails written on the dev and
user lists. You can search them here: https://apache.markmail.org//
The main site feels like it was written by a marketing major, lots of
flash and catchiness, but little in the way of detailed documentation.
Even the User Install Guide and the Developer Install guide read like
what they are, install guides.
For example:
Is cTakes the whole package, or just the front end?
* ctakes is a clinical nlp platform (vague enough?). I would say
"whole package", but extendable.
* It is built on Apache UIMA and allows users to create pipelines of
various nlp and i/o components.
* It comes with many components that have been built for clinical nlp.
* It is extendable; UIMA components from other sources can be placed in
the pipelines.
* There are front-ends for some tasks, such as running a pipeline or
creating a custom dictionary.
If it's just the front end, what's the back end?
* I would say that each UIMA component is a bit of back-end, as is the
controller that actually runs the pipeline.
* As mentioned above, you can extend it with non-ctakes back-end
components .
It mentions using my UMLS credentials, can you use a local copy of the
relevant UMLS data? If so how?
* If you are compiling and running the source then ctakes will
automatically download a default dictionary.
* If you are running a packaged binary then you'll need to manually pull
down a dictionary.
* Previous to ctakes 5 downlaoding, unzipping and copying the dictionary
was a manual process.
* If you are using v5 then you can run bin/getUmlsDictionary and a
simple gui will do it for you.
* You can also create your own custom dictionary.
* The wiki has a page on the dictionary creator gui.
* There are instructions on youtube that start with first steps.
Are the requirements listed, 1GB drive space, Oracle Java 1.8 the
minimum or the recommended? What about RAM or CPU? Is non-Oracle Java
acceptable? What about 1.17, the current LTS version?
== Java 1.8
> 2GB RAM (>= 4 recommended)
>= 64bit CPU
OpenJDK seems to be fine.
