Hi Richard,
Thanks very much for your replies (UIMA and webanno groups). I have
updated my research blog with your response and will hopefully soon get
to a point where I can follow the advice you have given.
Regards
James Kitching

Hi James,
<taking Apache UIMA hat off, putting UKP Lab hat on>
I'm working on the WebAnno (and DKPro Core) project. Thanks for checking it out
and providing feedback!

I had hoped that I could use webanno for this task however webanno does not
allow the direct import of UIMA components or UIMA output.
WebAnno [1] is an annotation tool. It's scope is not the building or running of
pipelines.
WebAnno can quite immediately consume XMIs created with the DKPro Core [2]
collection of UIMA components, since the built-in annotation types of WebAnno
are modelled after the DKPro Core types. Actually, all import/export filters in
WebAnno are UIMA components from DKPro Core.
WebAnno is not meant to be a universal XMI/CAS editor. It is meant to be a
user-friendly annotation tool. However, we internally use the UIMA CAS to
represent annotations.
To visualizes UIMA annotations in WebAnno, they need to be mapped to WebAnnos (cf.
brat's) interaction paradigms. To this end, WebAnno supports three specific type-system
design patterns (aka "layer types"): span, relation, and chain.
A "span" is basically a UIMA "Annotation". A "relation" is an annotation with two features pointing
to a "span" type. A "chain" is basically a variation of a linked list. Additional primitive features are also
supported.
If you want to use WebAnno with existing UIMA data, you can try this:
- define custom annotation layers in WebAnno that closely resemble the data you
wish to interface with
- export the layer definition as JSON
- edit the JSON file and change the type names "webanno.custom.XXX" into
whatever these types are called in your existing UIMA type sytem
- create a new project
- import the modified JSON layer configuration
For basic type system designs, this should work ok.
Cheers,
