Ruta: limited support of UIMA arrays

[Miguel Alvarez <mi...@gmail.com>]

Hi Peter,

 

You mentioned that the latest version of RUTA (2.4.0) introduces limited
support of UIMA arrays, but I don't seem to find anything in the
documentation about how to use it. Could you please give me an example of
what is possible? Is it possible to loop through an array of annotations
contained in a feature?

 

Thanks,

Miguel

... forgot to answer your question: Yes, it is possible to loop through
an array of annotations
contained in a feature.

Example from the unit test:

DECLARE Inner (FSArray a);
DECLARE Struct (FSArray as);
W{-> CREATE(Inner, a=W)}; // relink each word as the value of a feature
of Inner
Document{-> CREATE(Struct, as=Inner)}; // assign all Inner annotations
to a Struct annotation spanning the complete document
Struct.as{->T1}; // match on all Inner annotations contained in Struct
Struct.as.a{->T2}; // match on all word annotations contained in Inner
annotations, which are contained in each Struct annotation

Best,

Peter

Hi,

I did not add a real documentation by purpose since the functionality is
not implemented as it should. There was no time left to finish it. The
parts implemented right now should work nevertheless.

The existing functionlity can best be inspected in the unit tests:
/ruta-core/src/test/java/org/apache/uima/ruta/expression/annotation/AnnotationFeatureExpressionTest.java

The goal is that the users should be able to use UIMA arrays in a most
natural way in ruta rules without using extra language contructs.

Best,

Peter
