How to get matches using REGEX in Contextual Analysis?

dowdalj — Thu, 22 Aug 2019 20:39:30 GMT

I'm running into problems with the REGEX feature for custom concepts in SAS contextual analysis. I'm attempting to match strings of numbers with in textual documents. For example, one of my documents contains a sentence of the form

"Bob and Marie live at 1234 Main St"

I'm attempting to use the code:

REGEX: \d{4}

To match the string "1234". When I test/run the custom concept I'm getting no matches. Does anyone know how I can fix this?

Cheers,

SOLVED: I found my own mistake.

I was using

REGEX: \d{4}

ins SCA. I was not aware of the systems sensitivity to spaces at the beginning. The correction I needed to make was to remove it and write

REGEX:\d{4}
