Building on Kyle's and Jenn's responses – it seems to me the analogy is: grammaticality is to BLiMP and SyntaxGym as truth is to COMPS and plausibility (albeit that's not binary) is to EWoK. So, to apply our framework to those datasets, perhaps one should swap truth/plausibility for grammaticality?

Screenshot of a figure with two panels, labeled (a) and (b). The caption reads: "Figure 1: (a) Illustration of messages (left) and strings (right) in toy domain. Blue = grammatical strings. Red = ungrammatical strings. (b) Surprisal (negative log probability) assigned to toy strings by GPT-2."

New work to appear @ TACL!

Language models (LMs) are remarkably good at generating novel well-formed sentences, leading to claims that they have mastered grammar.

Yet they often assign higher probability to ungrammatical strings than to grammatical strings.

How can both things be true? 🧵👇

Not quite sure what you mean by a “complete” corpus. I do think the basic philosophical assumptions of frequentist probability are applicable to corpora, using the large-numbers-of-native-speakers thought experiment.

And productivity is a property of the asymptotic distribution, if I’m getting you.

If there were enough native speakers of the language living at once, you’d quickly get enough instances of the prefix for relative frequency estimation of the next token distribution. Too few humans are alive for this in practice, but that’s not a problem for theoretical validity of the construct!

You might be interested in this paper we did some time ago!

It supports your conjecture that, insofar as we think the “true distribution” is a valid theoretical construct (which I consider a highly defensible position), large-N Cloze would not give it to us.

#linguistics Bluesky: what are the best available quantitative measures of dialect/language mutual intelligibility? The more fine-grained, the better: I'm hoping to vividly illustrate at least one specific dialect continuum (e.g., the Romance languages of the Mediterranean coast)

Today in linguists are NOT KIDDING when we say that your capacity for language enables you to understand sentences that have never before been uttered in human history.

Absolutely, the Nature EiC has it completely backwards. Checking for errors and quality of data (and of math, code, and argumentation) is the most important work that reviewers can do.

The quotes from Nature EiC Magdalena Skipper about whether journals should be checking for errors/data quality as part of peer review are quite surprising to me.

TL;DR: prior expectations of what kids *want to say* is crucial. (Knowing how kids mispronounce words is too.)
