-----------------------------------------

             Summary: Problem with optional quantifiers and starting rule element annotation
                 Key: UIMA-3927
                 URL: https://issues.apache.org/jira/browse/UIMA-3927
             Project: UIMA
          Issue Type: Bug
          Components: ruta
    Affects Versions: 2.2.0ruta
            Reporter: Prokopis Prokopidis


Hi,

As the Ruta documentation mentions, "writing rules that contain a first rule element with
an optional quantifier is discouraged and will result in ignoring the optional attribute of
the quantifier." A solution for overcoming this is to declare a rule element as a starting
rule element by adding “@” directly in front of it. Thus, I am using ruta rules like

{code}
Token??{REGEXP(Token.posTag.value, "At")} // Article
Token??{REGEXP(Token.posTag.value, "Aj")} // Adjective
@Token{REGEXP(Token.posTag.value, "No")->MARK(Chunk, 1,3)}; // Noun
{code}

to mark nouns and optional pre-modifiers before them as chunks

However, the rule seems to match only Adj Noun sequences and not to match input like:

{code}
anArt|At anAdj|Aj aNoun|No
{code}

Thanks for looking into this.
