Hi!!! Knime Experts
Hope you are doing well.
Just need your help to compare certain words, so that i can progress in my workflow.
Requirement:
Input:
Name of Vendor:
Qwerty Private Limited
Qwerty Private Ltd.
Qwerty Pvt. Ltd.
All the three name is for single vendor, but in KNIME it’s showing 3 unique name, what steps shall i use or what changes shall i do that knime would consider all 3 as same.
Thanks in advance.
Hi @ravi13,
You can replace Pvt. and Ltd. (and any other similar abbreviations) with their complete forms or vice versa.
hi!!
@armingrudd Thanks, but it is not only for this vendor, their are many vendor, can you suggest any Specific node that I can use.
Can you provide more examples?
Sure like
We need to give the condition that knime need to consider as one name.

Thanks!! @HansS
just 1 question, how to get string similarity node?
that node is not in my arsenal
Hi @ravi13
The String Similarity node comes with the Paladian nodes. Additional extensions are available by enabling the Update Site in KNIME via File -> Preferences -> Install/Update -> Available Update Sites Add: http://download.nodepit.com/palladian/4.0 And then it can be installed: by selecting File -> Install KNIME Extensions (source: https://www.knime.com/community ).

@HansS Thanks!! 
Hi!! @HansS but using String similarity we gets only percentage of similarity. How to further use it to consider as one name.
That is a good question. I think you need a human in the loop. You have to find out, to what percentage you can go, to be sure (to some level) it is the same company. Maybe it is a good step to first “clean” your data and enrich it with some business logic, translated to rules (as @armingrudd suggested).

Still here ,involvement of human how will it benefit ?
All names are of same vendor, but one is 72.2% same & another is only 41.2% how to solve this issue, + this is only example for 1 vendor there are many more, in that situation we need to give different range for different vendor, it will become little bit tedious.
please guide … 
You may need to play with n value for n-gram. and see which one is working better.
Hi!!
@armingrudd Can you please guide me, I am stuck here?27_Data.xlsx (85.3 KB)
This are name of vendors
As @HansS suggested, you can first clean the strings (a bit) and then find similar names to replace.
Here I have built a workflow. I hope it helps. And of course, any feedback would be appreciated (@mlauber71, @ipazin, @HansS).

I have set the threshold to 0.8 but you can change it to your desired value.
Hi!! @armingrudd really kind of you.
Hi there @armingrudd,
didn’t look in details but seems in such cases Index Query node is better option. Used it couple of times and was really satisfied with outcome. I can try to create example and compare workflows and results.
