I have update the workflow by adding the Train Classifier Scope - This would allow you to train keyword based classifiers in cases where they are unable to classify the document.
I made a process based on your video, but I reported an error in one place： Data Extraction Scope: Index was outside the bounds of the array. And I cant fix it. Can you help me?
Hello Swati! the dataset that is created from the export extraction result is a collection of DataTables. This collection has has two DataTables - *Simple Field* and *Simple Field Formatted* This is the reason you are getting two message boxes. To check the names of the dataTables yourself you can add a message box in the for each loop with "table.TableName"
@@botbotgo4902 Thanks for the response. I did implement the for each loop with "table.TableName" and saw formatted and unformatted output. But if I unchecked the ‘FormatValuesIfPossible’ option in data extraction scope, then there will be duplication of data. How can I get only one set of data here?
Thanks for a great informative video. Just had a question in mind. If we have to define a keyword.json file for document classification then what is the use of texonomy.json?
Great video. What is not apparently clear for me is the documentPath variable you specified in the digitize document activity. I do not think you showed how you set that up, though I assume it is a variable that has the path of the file, correct ? If yes, alternatively we could also specify the file path directly in the Document path without creating the variable documentPath ? Thank you
Yes you understanding is correct. either we can directly specify the path in document path place or we can create a variable for same and pass it into specify area.
Anurag, can you please tell me how to extract line items from the invoice along with these details. I want to write it to excel preferably for a case when each document might have different number of line items
Hi Bro, I am not able to select 5 information on Page 1. I am only able to select one. Are you using shift or ctrl ki to select 5 information... I a,m working on 2 page PDF.Please suggest. I am waiting
Great video, thanks. One question: if you are satisfied with the results, can you remove the "Present Validation Station" command so it does not prompt the user everytime ? I have dozens of invoices to be processed in an unattended machine.
Hi, this is a good video. Actually I have question related to the intelligent ocr activities license. Is the activities free or must pay for the licenses. Thank you
Hi, while setting up the form extractor, you manually specify the location of document of 2 image (choose 2.jpg) , but at last you change document path location from 2 to 3.jpg. If we are manually specifying the location , how the form extractor fetches correct information!!
hey, file that you uploaded in the form extractor is just for generating a template. So no matter what document you read it will still work till the time the structure or the positions of various elements in the document remain same. Having said that if you try to extract data from an invoice with different structure, the extraction wont work.
@@botbotgo4902 Ok got it One more query, when i tried the same with create doc validation action and wait for validation action and comment out present validation it gives me that error "An extension of type 'UiPath.Activities.Contracts.Persistence.IPersistenceBookmarks' must be configured in order to run this workflow." ( I have created the storage bucket in orchestrator)
Hi may I know why you used both Form Extractor and ML Extractor? And also why does the workflow produce 2 sets of the same data table? What do i do if i only need 1.
Hey Sorry for replying late! 1. *Why i used both extractors* - I wanted to show that it is possible to combine extractors. It could happen that some attributes cannot be accessed by one of the extractors and in such case the other extractor will be used. Also the order of extractor usage is from left to right, that is, if the left most extractor is not able to get a particular attribute (or the confidence score is less than set threshold) only then the next extractor would be used. Also with configure extractor you have the possibility to decide which attributes are to be accessed by which extractor. 2. You get a list of tables (also know as *DataSet* ) and always take the first one from the list. -> *Dataset.tables(0)*
Hello @botBotGo, That was a great explanation.currently i am able to extract a single page with specific extraction fields,so how to loop through all pages in a pdf file with similar invoices ?
if you are using community version then u can only process documents with max 2 pages at once. one work around would be use some uipath pdf activities to breakdown your single pdf file into multiple pdf files and then loop through them.
A question how do I do so that it no longer shows the percentage or the "validation station" screen because every time it says to select the area 96% and it always takes it well? "Present Validation Station"
if you are so confident about the extraction confidence percentage then no need to use present validation activity in the flow, Directly you can check in the export result in the excel.
hey anurag, thank you for the wonderful explanation. i have one issue with the invoice date, its not comingb proper in csv file. its coming like : Key,Value "Month","5". my actual date in pdf is : May 26/20. it would be great if you could help on this..
Can you please check if the date is available in the text coming out of the digitize document activity. If not then it would not be possible to extract the date from any extractor. Then you might have to try with other OCR engines. If the date is available then you need to do some trial and error with different extractor activities.

Hello!! Thanks for the video. This is Rohit S. Lanjewar. Please help me how I can change confidence percentage of each field of Invoices in Present Validation station using Intelligent Form extractor in Document Understanding using UiPath.
Hello Sample Demo!! sorry for replying late. The confidence score is something that you set for a kind of extractor and if any attribute needed to be extracted by this extractor is below this score that field is not extracted. In such cases you can try using combination of extractors, where in if one extractor fails then the next extractor would be used. And if all fail then the user has to explicitly enter it.

Hey Year down! Sorry for replying late - I have made a video where i am solving a RPA challenge by extracting data from multiple pdfs - ua-cam.com/video/56AOiixQPKY/v-deo.html Let me know if this what you were looking for.
@Year Down this is mainly happening because Classifier is not able to classify your document. You would have to validate if the classification worked and if did not work then you need to extract data manually in present validation station. In order to check if classification worked 1. After the classification scope activity add an *IF Activity* 2. In The *IF Activity* check for condition if *classificationResult.Any* is True 3. In the true section move your *data extraction scope* 4. in the false section add an *assign activity* and assign extractionResults = Nothing
You overcomplicated the classification keywords by using "Add a new set" instead of just typing the right syntax into the first set to add multiple keywords. No need to have more than 1 set in these examples.
