[SOLVED] Detect below string using regex in uima RUTA

Detect below string using regex in uima RUTA

I'm trying to annotate below string as a type using regex in UIMA RUTA.

SAMPLE:

*******$10.00*

Other Variant:

*******$10.00***
*******$90.00*
*******$99**

Regex: *+\$\d+.\d+*+

UIMA REGEX:

SPECIAL{REGEXP("\\*+\\$\\d+.\\d+\\*+") -> MARK(AmC,1)};

I'm not able to detect as * represent greedy regex but as I'm using escape character() still something is missing.Any workaround?

PS: It's working for other regex engine but not working in UIMA RUTA

Solution

The REGEXP condition applies Java Pattern matches() on the covered text of the matched annotation of the rule element. In your example, this is SPECIAL which is a single special character. Thus, the regex tried to match on a single "*" and then anew the next character (excluding the digit and the period).

The REGEXP condition is not really suitable here. You should rather use a simple regex rule like:

"\\*+\\$\\d+.\\d+\\*+" -> AmC;
