New Audacious Research Project, In Codice Ratio, Bets on AI and OCR To Make Sense of Handwritten Texts in Vatican's Secret Archives (theatlantic.com) 111

A new project untangles the handwritten texts in one of the world's largest historical collections. From a report: The Vatican Secret Archives is one of the grandest historical collections in the world. It's also one of the most useless. The grandeur is obvious. Located within the Vatican's walls, next door to the Apostolic Library and just north of the Sistine Chapel, the VSA houses 53 linear miles of shelving dating back more than 12 centuries. That said, the VSA isn't much use to modern scholars, because it's so inaccessible. Of those 53 miles, just a few millimeters' worth of pages have been scanned and made available online. Even fewer pages have been transcribed into computer text and made searchable. If you want to peruse anything else, you have to apply for special access, schlep all the way to Rome, and go through every page by hand.

But a new project could change all that. Known as In Codice Ratio, it uses a combination of artificial intelligence and optical-character-recognition (OCR) software to scour these neglected texts and make their transcripts available for the very first time. If successful, the technology could also open up untold numbers of other documents at historical archives around the world.

      Indeed. That is why the hypemongers have come up with the term "weak AI", i.e. the AI without the "I". Classically this was called automation and here it is the subspecies called "pattern recognition".

      Incidentally, I disagree about the "few decades" for "strong/true AI". At this time we have zero indications it is even physically possible and hence, if it is possible, then > 50 years is a realistic timeline. No, human beings do not count as "reference implementation" for a number of reasons. It starts with us not even knowing what life is and we certainly cannot create it. Next, we do not know how humans generate intelligence and claiming that it must obviously be a physical process is just ignorant quasi-religious physicalism, not science. Just because we see the interface does not imply what is going on behind it. And we do not. Add to that that natural intelligence seems to require consciousness, where we know even less what it is or where it comes from. Now, I am not arguing for some form of mysticism, I am arguing that science is entirely clueless about what these things are and hence any predictions that strong AI is possible are vastly premature. Also note that what human beings have comes with free will (or at least some form of independence if you think free will does not exist) and that would pretty much make it useless as basis of a technical machine. All the problems with slave labor would apply. And in addition, there is indication that a technical implementation, if possible, of a human's mind would actually not be faster than the real thing and would need just the same slow education to be able to do anything worthwhile.

        Natural intelligence is correlated with sentience. But then carbon monoxide is correlated with ICE cars, but it is a byproduct, and cars can use other motive mechanisms. It's not clear if strong AI requires sentience, and intelligence is not well defined. I'd agree that pattern recognition is often a better term, which it used to be called when I started working in it. The AI research group was a distinct group, more concerned with symbolic processing.

        While I agree with your main point, it's worth pointing out that AI researchers have never been striving for "strong AI", rather "AI" as a technical term just means "solving problems that would seem at first to require intelligence", that is, difficult automation.

          BTW, we have a lot more knowledge about the origins of man's intelligence than you seem to realize. After all, it's been studied quite extensively. We understand what structures in the brain are responsible for what (mostly from study of brain damage). We understand to some extent the relationship between neurology and personality. We understand that consciousness is, neurologically, an extension of the ability to visualize yourself doing something without actually doing it. We understand that your actions can be driven from more primitive areas of the brain, and that's more likely to happen the stronger basic needs become.

          Not so. We do understand that damage to certain elements of the brain causes damage to certain functions. That does not imply these areas create these functions. Ever heard of cutting a cable preventing some technical function from being performed? Now, did that function originate in that cable? Also, as to consciousness, your statement is just pseudo-profound bullshit, probably spouted by some scientist unable to admit his cluelessness.

          All of that could be used to research machine intelligence, by following the one known successful approach. But why would anyone do that?

      According to TFS, the library is inaccessible because it hasn't been scanned.
      So their solution is to use AI driven OCR, which requires ... scanning.

      • Exactly my reaction. Once they scan them, they can put them on-line. Done and done.

      • Of course the documents need to be scanned, but I am surprised the OP used the term OCR, when, they should have used ICR: https://en.wikipedia.org/wiki/... [wikipedia.org] When you have hand written things the difference between an S and a 5 i sometimes contextual, but no so in part numbers that use both numbers and letters. Position sometimes helps. Also, a I might be slighly slanted one way \ or and other / - and in some cases, that is a slanted I and other times a forward or backward slash.

      Hell no. You don't digitize manuscripts destructively. There's not yet an official standard for digitizing medieval MSS, but the short version is that amateurs use cellphones or consumer cameras, wannabes use "archival scanners" (which require the document to be flat), and pros use a rig with medium-format cameras. but, for OCR, as their examples show, the current tech doesn't benefit from detailed images. This team is starting with the Papal Registers, which the ASV has been selling in a 300 dpi black-and-white (not grayscale) format for at least 15 years. 96% character recognition is about what other MSS OCR teams are getting. As TFA implies, people don't write letters; they write words, but you can't get the computational power to read words. So this inherently limits their approach, even with easy-to-read Carolingian Miniscule (the picture, btw, is of a "transitional hand" or "proto-gothic" more than CM). So they then choose between likely readings according to latinity. Cool, but with archival documents, the most valuable information for traditional research are the proper names, and these are usually less "Latinish" than the rest, so the net result is to increase the batting average slightly while grounding into a lot more double plays. In short: pilot project that uses digitizations from 2 generations back, produces results that aren't useful thanks to methodology dictated by current technology, and makes a few interesting tweaks. It would be cool to see, but first it'd be great to digitize and publish online the ASV. Of course, it's not so bad to go to Rome, go through the rigamarole of getting access to the ASV, and working directly with the originals. But the current catalog system dates from the eighteenth century, and is harder to read than the medieval manuscripts. So, you get what you can; if you're lucky they let you stay till 1600. Then you gotta find something to do in Rome until the next morning.

    But honestly, isn't it long past time to open them up to scholarly research.

    Scan them first. (How long do we estimate it will take?) Then start with the transcriptions, with or without OCR and deep learning.

    And let's stop kidding ourselves: there is no AI. AI is a campy buzz word that the hipsters throw around because they think it makes them look kewl when they use it. But it really just makes them sound stupid.

      Libraries commonly measure their capacity for books in shelf feet. In different areas of the library, books may be stored at different densities. In the periodicals section, a collection of journals or magazines may be stored at 30 issues per shelf foot, and in the reference section, maybe they only get 8 volumes per shelf foot.

      Uh, no. Not only are you misinformed about the hell thing, but the Church has actively supported making the documents available to wider audiences. There's no reason to be scared of what is said because the validity of the Church is not based on some kind of myth of absolute human perfection. It's funny that people have to make up silly stories about popes when actual history is scandalous enough, and yet it does not undermine the Church one bit. One of my favorites is Pope Pius II, who wrote a raunchy play about priests picking prostitutes before he became pope. But that doesn't undermine the Church. We don't need the pretense that it is comprised of perfect human beings, because its authority is not grounded on human perfection but rather divine election. Even the claim that the pope can teach infallibly does not mean that everything he says is infallible, nor that he is a particularly excellent human being.

      Perhaps the thing people are more afraid of seeing is how much documentary evidence actually speaks in favor of the Church. Many people will easily look past anything that doesn't complement their Dan Brown view of history.

    This sounds like a great idea, but it's likely to be extraordinarily complicated. Not only does handwriting differ from age to age, culture to culture, and place to place (just try reading 20th century German Sütterlin [wikipedia.org]), but many medieval manuscripts utilize complex systems of abbreviations called sigla [wikipedia.org]. Interpreting these can be very complicated because they are heavily context-dependent. One symbol can mean several different things. For example, a cross through a p can mean per, prae, or pro. A line over some letters can signify anything being cut out in-between. Just try figuring out what this inscription says: here [blogspot.com].

    Reading such abbreviations was probably expected to be relatively simple for the human brain to decipher both because the human actually interprets the text while deciphering symbols and because the original audience would have a better sense of how a particular community tended to use abbreviations.

    The task is not impossible for a computer, though. In most cases there are a limited number of words that could be signified by abbreviations, and it is possible to determine which word is most likely intended according to immediate context. However, that would require the machine to have a grasp of the Latin grammar, and even then not everything is going to follow perfect rules. There is so much potential interpretation involved. The AI component here does help with this inasmuch as it uses statistical data to optimize recognition, but it's still likely to run into many difficulties.

    The main innovation in TFA, as I see it, is that it responds to one of the major problems of reading old Carolingian minuscule. The letters are bunched together and there are times when you cannot be sure whether you are looking at two i's or a u, for example. The two can look exactly the same, not even just similar. The software in question attempts to handle this by recognizing individual penstrokes. Although I am not sure that this is 100% better than the older approach mentioned--recognizing whole words at a time--it does show significant promise because of its combination with AI. Perhaps some day it will be able to note, for example, that a certain author always strokes the i in a certain way. However, I'm sure there's going to be plenty of hurdles before getting to that point.

      Cuneiform texts have similar problems, and translation is a tedious process. I'm hopeful that new systems can help automate the process, but I'm not holding my breath waiting for it.

      For a hint at the problems, cuneiform was used for thousands of years, across several languages.

      In the early days, it was very terse, writing just the key words that would allow a literate native speaker of the language to reconstruct the real sentence. You would have a sentence written as "(picture of a man) (picture of a house) (picture of a noun that sounds like the verb to-build)". The reader would be expected to know that the intended sentence was something like "Lugale-e-mundu" or "The King built the house" and infer from the context (for example stamped on the still-wet bricks) that it meant "The king ordered the construction of these houses" or whatever.

      Over time, the symbols were pared down from little drawings to simplified figures, to abstract representations, to a couple of strokes that carry very little similarity to the original drawings.

      At the same time, the scribes got really inventive with the symbols. A written symbol could mean the noun that it once resembled, or it could mean a verb that sounds similar to the noun, or it could be a syllable, or it could be a marker to indicate that the next or previous stuff was a proper name, or the name of a deity.

      Additionally, symbols multiplied. They ended up with dozens of symbols for the "e" sound, for example, with different meanings. So you could have two sentences with different meanings that sounded exactly the same, but they could be written with exact symbols, or with generic symbols.

      To make things even more fun, Sumerian died out as a spoken language long before it faded as a written language. So, the scribes lost confidence in their writing and started gradually writing everything out longhand. This actually turned out to be fantastic for us, because it let us see the structure of the spoken language in ways that were completely hidden in older writings.

      And other cultures with completely different unrelated languages started using the writing system. So you might find a tablet that you can't translate because it is Akkadian written phonetically, for example. Even worse, it could be written as if it were Sumerian, so the structure would make sense, but the names wouldn't.

      That is actually how the Sumerian language was re-discovered ~1200 years after it died completely. There was a language still living enough for scholars to know what it sounded like, and ancient clay tablets written by people who had spoken that language centuries before.

      The scholars noticed two things. First, there was a huge pile of those tablets that were completely incomprehensible. And second, that the ones they could read showed a writing system that was a hilariously bad fit for the written language. Like the subject, object and verb order was SVO when spoken, but SOV when written, and the written language was full of markers that were not present in the spoken language, and the markers in the spoken language were completely absent in the writing system.

      Eventually, they figured out that they were looking at several different languages, and they were able to reconstruct Sumerian from that mess.

      Anyhow, to process one of these tablets, you need to examine the strokes in the clay and match them to symbols. Then you take a wild guess at which language you think it might be and see if you can find a meaningful translation in that language. If not, you go back to pick a different language and try again. And again, and again.

      Because of the tedium of doing this by hand, and the very short supply of people who know these languages and can do the work, our museums quite literally have tons of these tablets that have never been translated.

      Other ancient writings face a similar problem. We have more of them in storage than we know what to do with. It was big news a few weeks ago that a 1500-year old C

    This is a two part problem, and if they are at all worried about the effort to OCR the documents, then they have the cart before the horse, IMHO. This isn't your average library. You cannot use a high speed book scanner on ancient books. Each will need to be brought out, and each page carefully turned by gloved hands. I am not sure it is much of an exaggeration to say that you could probably hire a few typists to transcribe the text faster than they can do the actual imaging. Once it is digitized, a much larger group of scholars can be included on the difficult task of making it computer readable.
