My eventual goal is to transform thousands of pdfs into a corpus / document term matrix to conduct some topic modeling. I am using the pdftools package to import my pdfs and work with the tm package for preparing my data for text mining. I managed to import and transform one individual pdf, like this:

PDF scraping: get company and subsidiaries tables

Asked 2021-May-26 at 06:59

I am trying to scrape this PDF containing information about company subsidiaries. I have seen many posts using the R package Tabulizer but this, unfortunately, doesn't work on my Mac for some reasons. As Tabulizer uses Java dependencies, I tried installing different versions of Java (6-13) and then reinstalling the packages, still no luck in getting this to work (what happens is when I run extract_tables the R session aborts).

I need to scrape the whole pdf from page 19 onwards and construct a table showing company names and their subsidiaries. In the pdf, names start with any letters/number/symbol, whereas subsidiaries start with either a single or double dot.

So I tried with pdftools and pdftables packages. The code below provides a table similar to the one on page 19:

Like @Justin Coco hinted, this was a lot of fun. The code ended up a bit more complex than I anticipated, but I think the result should be what you imagined.

I used pdf_data instead of pdf_text so I can work with the position of words.

locating specific columns in a pdf table from R

Asked 2021-May-17 at 11:54

I was wondering how I could locate the 2nd & 3rd columns from left in the table on the last page (page 18) of the this pdf document.

I'm using pdftools package, I'm wondering if there is a way to extract the 2nd & 3rd columns from left which are just numeric data?

...

ANSWER

Answered 2020-Dec-31 at 07:03

Making use of some tidy verse packages this could be achieved like so:

Filter for the values in the 2nd and 3rd column. The 2nd column values start at position x=189, the 3rd col at x=252.
Additionally to make sure that we only get the values I first convert to numeric whereby all text gets converted to NA. Note: One of the values has a comma as decimal mark, which I first had to remove.
After getting the values I reshape the dataset using pivot_wider for which I add a row id.
Finally I rename the cols.

Answered 2021-May-06 at 03:27

There seems to be an issue with pdf_convert handling one-page raw pdf data (it wants to use basename(pdf) under these conditions), so I have edited that function so that it also works with the second attached pdf file.

If you only need the first file then you could run this with the original pdf_convert function, but it will give an error with the second file.

If you are interested in rendering raster graphics from the attached files this worked for me:

c# adobe acrobat SDK: file is still locked after SDK quit

Asked 2021-Apr-29 at 11:28

I'm working with C# and adobe acrobat SDK. When the program throws an error due to the pdf already being compressed I want to move the pdf.

However, C# complains that the file is being used by another process and I know it has to do with the SDK and not another program. After some debugging I found out that compressPDFOperation.Execute is the culprit.

How can I close it so that I can move the file?

ANSWER

Answered 2021-Apr-29 at 11:28

I've found a solution , it's not best practice but I don't know an other way to do it. I've declared all the variables used to execute the compression (sourceFileRef, compressPdfOperation, ...) before the try catch statement and after result.SaveAs(...) I set those variables to null and run the garbage collection.

Scraping PDF tables with empty Cells

Asked 2021-Apr-02 at 08:01

I'm using R to pull data from PDFs and so far it has been going well. I just opened up a new batch of PDFs and saw that I have to figure out how to account for empty cells. I haven't found a way to do this, and I have hundreds of pages that I need to go through.

I've included some sample data. I haven't found a way to attach the PDFs here, and these are not posted on the web anywhere. I saved df as a CSV, then copied and pasted that into a word document which I saved as a CSV for this example. Screenshot attached as well.

Answered 2021-Apr-01 at 02:09

This looks like a good scenario to use the tabulizer package. It works really well when there are nicely formatted tables like this in the PDF. See the vignette. The best function here for you would be tabulizer::extract_tables. It should also recognize the blank spaces as empty values assuming the PDFs are all well formatted like this.

All articles have a pdf link to them so I've been trying to pull the pdf link and scrape the entire text onto a csv.

Looking at your last function, if I understand correctly, you want to take the url and scrape all the text into the a data frame/tibble and then export it to a csv. Here is how you can do it with just 1 article, and you should be able to loop through some links with a little manipulation (apologies if I am misunderstanding):
