Peter Klügl commented on UIMA-3382:
-----------------------------------
Short answer: no that is not possible with word lists, but...
The wordlists in UIMA Ruta are designed to work as a dictionary sensible to the
current filtering settings of your rule script. There are several kind of word
lists, but internally they are represented as a trie, a tree structure of
chars. This can greatly improve the performance, but makes the usage of regular
expression impossible (at least as it is implemented right now).
UIMA Ruta also supports simple regexp rules:
http://uima.apache.org/d/ruta-current/tools.ruta.book.html#ugr.tools.ruta.language.regexprule
You could use them to create a list of regular expression in a Ruta script like:
{noformat}
"azithromyci.?"-> Medication;
"azithromyci.+susp"-> Medication;
{noformat}
btw, you can also ask question on the mailing lists.
> Ruta: REGEXP from WORDLIST
> --------------------------
>
> Key: UIMA-3382
> URL: https://issues.apache.org/jira/browse/UIMA-3382
> Project: UIMA
> Issue Type: Question
> Components: ruta
> Reporter: Olga Patterson
> Priority: Trivial
> Labels: features
>
> WORDLIST is defined as a list of text items. What if I have a list of regular
> expressions that I want to mark as the same type. Is there a command that
> would do it?
> My use case is that I want to find medication statements in text, but there
> is a large variation in spelling and dose description, so regular expressions
> are a more concise way to cover all possible cases. So I was trying to use
> syntax below, but the only matches were for those cases where there was a
> single word without special regex syntax.
> DECLARE Medication;
> WORDLIST MedicationList='Medication.regex';
> Paragraph{-> MARKFAST(Medication, MedicationList, true,1)};
> What can I change in the rules so that the items in MedicationList are
> treated as regular expressions.
> Thank you.
