I am working on entity extraction in Pega. I have requirement to match a policy number which has 3 parts:
1) Optionally 1 would be first character in policy. It is optional
2) alphanumeric of length 2 followed by optionally Hyphen or Space
3) alphanumeric of length 3
So some examples of formats are:
AB-CDE, AB CDE, ABCDE, 1AB-CDE
23-456, 23 456, 23456, 123456
AB-2B4, AB-B2C, A1-2B4, 2A-34B, 12A-34B, 123-45C etc.
I am facing problem whenever policy number is starting with 2 or 3 digits or it don't have any space or hyphen.
For example 12A-34B, 123-45C, 23456, 123456.
I have written below script:
PACKAGE uima.ruta.example;
Document{-> RETAINTYPE(SPACE)};
("1")+? ((NUM* W*)|(W* NUM*)){REGEXP(".{2}")} ("-"|SPACE)? ((NUM* W* NUM*)|(W* NUM* W*)){REGEXP(".{3}")->MARK(EntityType,1,4)};
((NUM* W*)|(W* NUM*)){REGEXP(".{2}")} ("-"|SPACE)? ((NUM* W* NUM*)|(W* NUM* W*)){REGEXP(".{3}")->MARK(EntityType,1,3)};
This code is working fine for patterns having space/hyphen like: AB-CDE, AB CDE, 1AB-CDE. But not working if don't have space and hyphen or pattern starts with 2 or 3 digits.
Please help to write correct pattern. Thanks in advance.
The UIMA Ruta seed annotation NUM, covers the whole number. Therefore, examples like 23456, 123456 cannot be split in subannotations by Ruta.
A solution would be to use pure regexp to annotate all the mentioned examples:
"\\w{2,3}[\\-|\\s]?\\w{2,3}" -> EntityType;
