I'm having a challenge to process and perform counts on text fields. I have about ~100k rows, Below is a snapshot of the data set
DocNo Section Reference Description
111 126.96.36.199 This is case1
124 Chap 4 Section 188.8.131.52 This is case2
100 Chapter 2 Section 2 This is case3
1985 S184.108.40.206 This is case4
The objective is the find the count of Section References for each document, Presently I'm using Regex Expression to capture valid refereces (like 220.127.116.11 ) and using cell splitter to put them in seperate columns and doing the counts with drill down (using Tableau Hierarchy feature), but the I'm not sure how do I handle case 2,3 and 4 with all the text fields in it.
Is there a good(or naive) solution in KNIME I can implement, like fuzzy match etc. and get counts for all section references, it doesnt have to be efficient or optimized.
Appreciate any leads, Thanks!
