Filtering of documents using document similarity

I have 100 comments that I process and run Document Similarity against. Works great, but I'm only interested in finding documents containing specific words, say "workload". So I filter the example set, rerun the process, and document similarity gives me the results on those documents only containing "workload". Perfect. Problem is, by filtering it also remaps the IDs of the documents to the filtered set so I no longer know their original document IDs. This makes it very difficult to find the originals because a .73 similarity between doc ids 1 and 17 in the filtered set does not map to documents 1 and 17 in the original non-filtered data set.

Is there a way to keep the original IDs in the filtered dataset?

Hi!

After filtering you could use Generate ID. It adds exactly the same numbers (the document number) to the example set as a new attribute. Then you can use Remember or Store to get a copy of the data with the IDs and then Join to get back the matching document text.

Here's an example process.

It is admittedly a bit involved but you can get the desired result with a few additional operators.

Thanks for your great example, Balázs. After I posted the question and thought about it a bit more, I thought maybe generate attributes to match the original IDs? But your solution is better and gives me more ideas to work through. Thanks again.
