The Senate’s electronic filing system came into effect a couple years ago ph n m m abbyy finereader 12 professional free download Senator Bernie Sanders is ph n m m abbyy finereader 12 professional free download example of a Senator who has moved from paper to the electronic filing system:. Extracting data from scanned images is one of the most common and most difficult data wrangling tasks, such that OpenSecrets aka The Center for Responsive Politics pitched a civic hackathon challenge to build a solution for efficiently parsing Congressmembers’ personal financial disclosures.

My writeup here is meant as a quick overview of the effectiveness of using ABBYY FineReader for Mac in producing usable, perhaps even delmited data from the scanned disclosure forms. Note that I’m not attempting to solve the problem of how to clean up the imperfect OCR results and insert them into a database, and how to automate it as a batch process.

Just extracting text, even semi-accurately, from a single scanned form is a hard challenge on its own. If all you care about is the actual personal finances of CongressmembersOpenSecrets has you covered. My initial takeaway: FineReader is remarkably good for this task; in a later walkthrough I’ll explain how to apply this in semi-automated fashion across all the forms or any other set of scanned papers. For the purposes of brevity, this writeup focuses on the Senate financial disclosures – the OCR challenge for both chambers of Congress is fundamentally the same.

The Senate’s financial disclosure database can be found here :. If you want to visit the direct links I provide, you’ll need to visit the Senate site with your browser and manually agree to the site’s terms of use. This will start a browser session that allows you to access the direct links. Here’s what an annual report on personal finances for looks like when it’s electronically-submitted, courtesy of Senator Marco Rubio :. Rubio’s financial report, which you can visit here without going through the Senate site.

As you can see, the HTML is детальнее на этой странице to parse as machine-readable data. So let’s dispel once and for all with this ph n m m abbyy finereader 12 professional free download that Senator Rubio doesn’t know what he’s doing.

He knows exactly what he’s doing. And here’s what that same report looks like when it’s submitted on paper, courtesy of Senator Dianne Feinstein :. Here’s what one of the scanned pages looks like:. It’s important to note that even though Senator Rubio’s electronic form is easy to read, programmatically, there’s still the challenge of creating a data schema that you can import his financial data into. That same challenge exists for Senator Feinstein’s paper form, except with the смотрите подробнее and exponentially more challenging task of just extracting the data.

This challenge is what necessitates the use of optical character recognition technologyaka OCR. That is, convert a picture of the letter into a digital plaintext representation that can be read by a text editor: a. The process of turning images into string literals is extremely difficult, and doing it at high rate accuracy is beyond most development shops smaller than Google.

The additional challenge of seeing that the images represent tabular data is of itself another, non-trivial challenge. There are open-source OCR programs, of which Tesseract is the most well-knownbut they don’t generally do the task of recognizing tabular data note: software such as Tabula deals with actual tabular data, посетить страницу scanned images.

Windows users have access to FineReader 12 Professional and Corporate — and, I’m betting, more tech support and updates. Financial Disclosure Reports are not text-based PDFs, but rather scanned-in images, meaning OCR optical character recognition software must be used to extract the data. This is then cleaned up and turned into a csv file using Python. I haven’t used the cloud service and I agree that the cost is probably prohibitive for most projects. So for this writeup, I’m focusing only gb home size free download windows 10 the desktop application — I imagine both the Windows and Mac versions have similar OCR effectiveness.

I’ll cover the process of how to use the Desktop application to perform batch OCR in another writeup. The electronic system only came into effect a couple years ago and Senator Alexander’s latest annual report was submitted electronically ph n m m abbyy finereader 12 professional free download, so good on him. When importing that single image into FineReader, this is what FineReader purports to “see”, in terms of the OCRable regions of the page:.

But we want a table — i. Pretty good! You can download the Excel file here. Not only is there significantly more ink and smudged ink to deal with, but there are vertical table headers and other complex tabular features to process.

Definitely not as clean as the previous example, but to be honest, ph n m m abbyy finereader 12 professional free download better than what I had expected. I’m kind of shocked that it managed to make sense of the vertically -oriented headers. You’d still have a long ways to go before you could put this into a database, but FineReader’s output gives you a lot of options for heuristics to simplify the translation process.

And what if you ph n m m abbyy finereader 12 professional free download need to very quickly see if anyone at anytime has ever owned assets in “Acme Co.

At the very least, FineReader provides very greppable text data. Here’s the Excel spreadsheet. That can’t be that hard, right? But take a closer look And also, a bunch of hand-written scrawl that we can safely assume will not be accurately parsed.

Yep, that’s basically unusable. Not so much because of the character accuracy in fact, FineReader translates the X’ed boxesbut because the tabular structure isn’t preserved in the way you’d hope it to be.

You can download the spreadsheet file here. And the PDF with embeddable text here. What about regular letters of prose? Here’s the original page from Sen. Alexander’s report, with its original neck-wrenching-orientation.

Because we don’t care about tabular data, I’ve used Poppler’s pdftotext utility to just extract the text, along with pdftotext’s -layout flag to produce it in such a way that the whitespace is similar to the visual layout of the PDF. Not bad. There are a few problems that would be significant hurdles if you wanted to grep across the text, including a comma where a decimal point should be in And the somewhat inexplicably consistent translation of of to o f :.

For this test, I used Tesseract version 3. One of the things Tesseract won’t do is process GIFs which is, for whatever reason, the preferred image format of the Senate disclosure databaseso you’ll need something ph n m m abbyy finereader 12 professional free download ImageMagick. And, Tesseract doesn’t seem to do automatic orientation detection or at least I don’t know how to invoke itso you’ll have to reorient the image before passing it to Tesseract to OCR.

The command-line sequence with ImageMagick which provides the convert command to do image transformations looks like this:. It produces a file named tesseract. Because Tesseract, by default, produces a plaintext stream, there is no option to use pdftotext -layout on ph n m m abbyy finereader 12 professional free download output you can, however, configure Tesseract to output HOCR data, which gives you the option of manually determining spatial regions for yourself, which projects like Jacob Fenton’s whatwordwhere aim to do.

For being free, Tesseract does a very capable job. I didn’t bother to do a real analysis of its accuracy versus FineReader, though, other than to note that it correctly interpreted of as of. Turning data that was “optimized” for paper — whether it be digital PDFs or scanned images simply packaged as PDFs — will be a significant computational task as long as humans require human-readable information.

In terms of OpenSecrets’s call-to-arms to automate the processing of Congressional paper formsgood OCR is not enough, we need a system to batch collect and process the documents, which will be its own writeup. It’s worth noting, though, that OpenSecrets isn’t waiting around for magic OCR to come around: they’ve processed the financial disclosure forms the old-fashioned way — human-powered reading and data entry — and have generously provided their results in browsable and searchable form on the Здесь Finances section of their eponymous political transparency site:.

Using ABBYY FineReader There are open-source OCR programs, of which Tesseract is the most well-knownbut they don’t generally do the task of recognizing tabular data note: software such as Tabula deals with actual tabular data, not scanned images. So let’s get right into interesting part: the OCR of tabular data. Here’s one of the simpler variations of forms in the Senate disclosures: Note: this example and others come from Senator Lamar Alexander’s Annual Report mirrored here at OpenSecrets.

And here’s the result: Pretty good! Less simple table OK, узнать больше здесь here’s a much less simpler table: Not only is there significantly more ink and smudged ink to deal with, but there are vertical table headers and other complex tabular features to process.
