Meaning at the joints

Notes for a post:

Plato said (Phaedrus, 265e) that we should “carve nature at its joints,” which assumes of course that nature has joints, i.e., that it comes divided in natural and (for the Greeks) rational ways. (“Rational” here means something like in ways that we can discover, and that divide up the things neatly, without overlap.)

For Aristotle, at least in the natural world those joints consist of the categories that make a thing what it is, and that make things knowable as those things.

To know a thing was to see how it’s different from other things, particularly (as per Aristotle) from other things that they share important similarities with: humans are the rational animals because we share essential properties with other animals, but are different from them in our rationality.

The overall order of the universe was knowable and formed a hierarchy (e.g. beings -> animals -> vertebrates -> upright -> rational) that makes the differences essential. It’s also quite efficient since anything clustered under a concept, no matter how many levels down, inherits the properties of the higher level concepts.

We no longer believe that there is a perfect, economical order of things. “We no longer believe that there is a single, perfect, economical order of things. ”We want to be able to categorize under many categories, to draw as many similarities and differences as we need for our current project. We see this in our general preference for search over browsing through hierarchies, the continued use of tags as a way of cutting across categories, and in the rise of knowledge graphs and high-dimensional language models that connect everything every way they can even if the connections are very weak.

Why do we care about weak connections? 1. Because they are still connections. 2. The Internet’s economy of abundance has disinclined us to throw out any information. 3. Our new technologies (esp. machine learning) can make hay (and sometimes errors) out of rich combinations of connections including those that are weak.

If Plato believed that to understand the world we need to divide it properly — carve it at its joints — knowledge graphs and machine learning assume that knowledge consists of joining things as many different ways as we can.

[eim][misc] Tagging rises

Both Facebook and Apple have announced the use of tags. Yay!

Tags have continued to percolate through the ecosystem after their most auspicious introduction in Delicious.com. (Note the phrase “most auspicious”; tags have always been with us.) It’s great to see them increase both because they are a great way to get use out of the craziness while preserving it in its original form for others, and because there is great value in scaling tags, as Flickr has shown.

So, yay for tags. And yay for the crazy.

[eim][misc] Too big to categorize

Amanda Filipacchi has a great post at the New York Times about the problem with classifying American female novelists as American female novelists. That’s been going on at Wikipedia, with the result that the category American novelist was becoming filled predominantly with male novelists.

Part of this is undoubtedly due to the dumb sexism that thinks that “normal” novelists are men, and thus women novelists need to be called out. And even if the category male novelist starts being used, it still assumes that gender is a primary way of dividing up novelists, once you’ve segregated them by nation. Amanda makes both points.

From my point of view, the problem is inherent in hierarchical taxonomies. They require making decisions not only about the useful ways of slicing up the world, but also about which slices come first. These cuts reflect cultural and political values and have cultural and political consequences. They also get in the way of people who are searching with a different way of organizing the topic in mind. In a case like this, it’d be far better to attach tags to Wikipedia articles so that people can search using whatever parameters they need. That way we get better searchability, and Wikipedia hasn’t put itself in the impossible position of coming up with a taxonomy that is neutral to all points of view.

Wikipedia’s categories have been broken for a long time. We know this in the Library Innovation Lab because a couple of years ago we tried to find every article in Wikipedia that is about a book. In theory, you can just click on the “Book” category. In practice, the membership is not comprehensive. The categories are inconsistent and incomplete. It’s just a mess.

It may be that a massive crowd cannot develop a coherent taxonomy because of the differences in how people think about things. Maybe the crowd isn’t massive enough. Or maybe the process just needs far more guidance and regulation. But even if the crowd can bring order to the taxonomy, I don’t believe it can bring neutrality, because taxonomies are inherently political.

There are problems with letting people tag Wikipedia articles. Spam, for example. And without constraints, people can lard up an object with tags that are meaningful only to them, offensive, or wrong. But there are also social mechanisms for dealing with that. And we’ve been trained by the Web to lower our expectations about the precision and recall afforded by tags, whereas our expectations are high for taxonomies.

Go tags.

[misc] The US GAAP Taxonomy is Miscellaneous

Well, here’s an application of some of the ideas in Everything is Miscellaneous that I wasn’t expecting: The US GAAP Taxonomy. A post at the XBRL Business Information Exchange says:

The US GAAP Taxonomy was built by the accounting standards setter, the FASB. It was built by accountants. It is a consensus-based product. Not one SEC XBRL filer uses the US GAAP Taxonomy as is to file with the SEC. Every SEC reorganizes the US GAAP Taxonomy.

But the US GAAP Taxonomy is not built to be reorganized. The structure of the taxonomy is more like a book. Can the US GAAP Taxonomy be reorganized? Of course it can. But it is certainly not optimized to allow for reorganization and reorganization is not even mentioned in the design characteristics. As such, it will cost more and be harder to create and maintain these reorganizations.

So how do you make it easier to reorganize? Many smaller pieces which can be put together as needed is vastly easier for a computer to deal with than having one large piece and trying to break that piece apart. That is one example of what can be done. Another is communicating the metadata which exists in the taxonomy, for example the information modeling patterns employed. A third is to make the existing metadata real metadata, rather than burying it in the labels of the concepts. Another is to add more metadata.

The post points out that it’s not that everything about that taxonomy should thrown into a big pile. There are key data points required by law and to achieve financial integrity. Still, this is not a place I would have thought miscellanizing would help. It seems, however, that I may well be happily wrong.

Mr. Dewey, tear down that wall!

Tim Spalding, founder of the estimable LibraryThing, is calling on us all to create an open shelves classification project to replace Dewey and his pals. LibraryThing is a brilliant implementation of a what a library built on a social network of readers can be, so I’m excited about Tim’s new idea.
