How to use Type comparison?

[Reza Hay <re...@gmail.com>]

Hi All,

The following Ruta (2.6.0) statement gives me correct answer:
TYPESYSTEM Types.DKPROTypeSystem;
IMPORT de.tudarmstadt.ukp.dkpro.core.api.syntax.type.dependency.ROOT FROM Types.DKPROTypeSystem AS DEP_ROOT;

DEP_ROOT{DEP_ROOT.Governor.pos.PosValue == "VBZ" -> LOG("root: " + DEP_ROOT.Governor.pos.ct)};

However, the following statement (comparing types) results in empty output:
DEP_ROOT{DEP_ROOT.Governor.pos == VERB -> LOG("root: " + DEP_ROOT.Governor.pos.ct)};

Isn't it possible to compare types as I did?

Regards,
Reza

Hi,


there is a mixup between annotations and types here and type expressions
on annotation expressions are not yet implemented. Else you could write
DEP_ROOT.Governor.pos.type==VERB;


Something like this could mabye help you:


DEP_ROOT.Governor.pos{IS(VERB)};


or


DEP_ROOT<-{DEP_ROOT.Governor.pos{IS(VERB)};};


if you do not want to change the match context of the rule element.


btw I personally use label expressions more and more since they avoid
ambiguities when resolving an annotation given a type expression.


root:DEP_ROOT<-{root.Governor.pos{IS(VERB)};};



Best,


Peter
