-------------------------------------
Summary: | and & REs may miss matches
Key: UIMA-6324
URL: https://issues.apache.org/jira/browse/UIMA-6324
Project: UIMA
Issue Type: Bug
Components: Ruta
Affects Versions: 2.8.1ruta
Reporter: Michael Stenger
Fix For: 2.9.0ruta
Hey Peter...
I have two examples where rules using | and & presumably miss out matches.
However, this may be cause by other steps of the execution process than these
rule elements since I couldn't find a bug in ComposedRuleElement class.
Hopefully, you can enlighten me on this. I used the Workbench to test this:
* Example 1
Text:
{noformat}
A B A B
{noformat}
Script:
{noformat}
DECLARE A, B, C;
"A" {-> A};
"B" {-> B};
((B A) | ("B" "A")){-> C} W;
{noformat}
I'd expect a C annotation on "B A" here, but it only outputs the A and B
annotations from the first 2 rules. On the other hand, if I replace the | with
&, it creates a C as exprected. That doesn't seem right. | should be a less
strong condition.
* Example 2
Text (same):
{noformat}
A B A B
{noformat}
Script:
{noformat}
DECLARE A, B, C;
"A" {-> A};
"B" {-> B};
((B A) & ("B" "A")){-> C} @W;
{noformat}
Here, its the other way around, meaning that a C annotation is created using |,
but not &. I don't see way either the direction or the use of &/| should make
any difference in this case.
Thanks,
Michael
