Document Understanding Best Practises / REFramwork

Help Document Understanding

Dear Community,

I’m currently trying to build a template for the whole document understanding process / life cycle and came across a few problems regarding best practises when combining document understanding with the REFramework.

This is the basic process of document understanding according to UiPath:

1122×416 40.2 KB

In my case, I’ve added a 3.5 as well, which is another validation station as in step 5, for documents where the classifier is below a certain confidence level.

So my process basically looks like this:

documentUnderstandingProcess
documentUnderstandingProcess1531×521 24 KB

My big question is, how to split up the process in order to maximize parallelism. I cannot wait with the process until a user has finished their classification or extraction tasks because I might have to extract data from hundreds or thousands of documents.

So I was thinking about using queues between a lot of the steps and having several different bots (or rather processes).

Example: Once the document is classified, the classification results get put into a queue for further processing. This happens when either the bot or a person does the classification. Same for the data extraction, results get put into a queue for further processing. I’ll probably also need queues for retraining the models.

This would mean I’d have to split my process into 3 different parts connected by queues: Digitizing + Classification, Data Extraction and further processing of the extracted data.

Each of those parts would then use the REFramework.

Another idea would be to create an Orchestration Process and run this for every single file which needs to be processed. This is definitely easier to implement but there might be a time with hundreds or more processes waiting for user input and I’m not sure how this is handled.

The first approach is definitely scaleable with simply adding more robots, not sure about the second way.

I’d be great if we could discuss those approaches or you could even share your own way of tackling the whole document understanding process.

Hi @T0Bi!

Your observations are absolutely spot on!

We are currently exploring both approaches you mentioned:

  1. Splitting the processing flow into smaller sub-processes that pass data to each other through Queues. Orchestration Processes will do just fine, you don’t necessarily need the REF as long as you take care of exceptions & retry mechanisms.
  2. Using an Orchestration Process to process an input file end-to-end

In the first scenario, make sure you don’t leave any queue items as In Progress when a suspension point is reached. Otherwise, if the action is not completed within 24h, the item would get Abandoned.

In the second scenario, a dispatcher process simply starts a job for every input file. Scaling it is as simple as adding more robots to the “processing pool” (environment or modern folder, depending on the case).

Just for awareness, without any promises on availability: we are working on an out-of-the box Studio RPA template that would implement the logging, error handling & retry mechanisms specific for Document Understanding processes.

Cheers,
Alex.

Hi @Alexandru-Luca

thanks for your answer!

I haven’t thought about leaving queue items as In Progress will lead to them getting “Abandoned” after a while, that’s a really good point.

For now I’ll stick with a dispatcher and an Orchestration Process, it seems like the easiest way.

I’m looking forward to seeing such a template, I think it would make the Document Understanding process faster and easier to implement.

Cheers,
T0Bi

Hi @T0Bi,
Are there any updates on your progress or UiPath’s progress on combining the REFramework with Document Understanding best practices?

Thanks!

As @wasea already stated, we’re using the Document Undestanding Framework as well.

It’s actually really really good
