• Title: Syntactic Variation Across the Grammar: Modelling a Complex Adaptive System
• Authors: Jonathan Dunn
• Abstract summary: We model dialectal variation across 49 local populations of English speakers in 16 countries. Results show that an important part of syntactic variation consists of interactions between different parts of the grammar. New Zealand English could be more similar to Australian English in phrasal verbs but at the same time more similar to UK English in dative phrases.

• Abstract: While language is a complex adaptive system, most work on syntactic variation observes a few individual constructions in isolation from the rest of the grammar. This means that the grammar, a network which connects thousands of structures at different levels of abstraction, is reduced to a few disconnected variables. This paper quantifies the impact of such reductions by systematically modelling dialectal variation across 49 local populations of English speakers in 16 countries. We perform dialect classification with both an entire grammar as well as with isolated nodes within the grammar in order to characterize the syntactic differences between these dialects. The results show, first, that many individual nodes within the grammar are subject to variation but, in isolation, none perform as well as the grammar as a whole. This indicates that an important part of syntactic variation consists of interactions between different parts of the grammar. Second, the results show that the similarity between dialects depends heavily on the sub-set of the grammar being observed: for example, New Zealand English could be more similar to Australian English in phrasal verbs but at the same time more similar to UK English in dative phrases.

  The current paper looks at diachronic trends in syntactic language change in both English and German, using corpora of parliamentary debates from the last c. 160 years. We base our observations on five dependencys, including the widely used Stanford Core as well as 4 newer alternatives. We show that changes in syntactic measures seem to be more frequent at the tails of sentence length distributions.

  We employ visual and linguistic representations of words sourced from pre-trained artificial neural networks. We find that the representation of verbs is generally more variable and less discriminable within domain than the representation of nouns. Visual variability is the strongest factor that internally drives verb learning, followed by visual-linguistic alignment and linguistic variability.

• Stability of Syntactic Dialect Classification Over Space and Time [0.0]
  This paper constructs a test set for 12 dialects of English that spans three years at monthly intervals with a fixed spatial distribution across 1,120 cities. The decay rate of classification performance for each dialect over time allows us to identify regions undergoing syntactic change. And the distribution of classification accuracy within dialect regions allows us to identify the degree to which the grammar of a dialect is internally heterogeneous.

  We investigate whether structural supervision improves language models' ability to learn grammatical dependencies in typologically different languages. We train LSTMs, Recurrent Neural Network Grammars, Transformer language models, and generative parsing models on datasets of different sizes. We find suggestive evidence that structural supervision helps with representing syntactic state across intervening content and improves performance in low-data settings.

  We investigate whether there are systematic sources of variation in the language models' accuracy. We find that certain nouns are systematically understood better than others, an effect which is robust across grammatical tasks and different language models. We find that a novel noun's grammatical properties can be few-shot learned from various types of training data.

  We studied whether a modern artificial neural network trained with "deep learning" methods mimics a central aspect of human sentence processing. Although the network was solely trained to predict the next word in a large corpus, analysis showed the emergence of specialized units that successfully handled local and long-distance syntactic agreement. We tested the model's predictions in a behavioral experiment where humans detected violations in number agreement in sentences with systematic variations in the singular/plural status of multiple nouns.
