Evaluating syntactic proposals using minimalist grammars and minimum description length

Ermolaeva Marina

Journal of Language Modelling

2023

Vol. 11, No. 1

67--119

Many patterns found in natural language syntax have multiple pos-sible explanations or structural descriptions. Even within the cur-rently dominant Minimalist framework (Chomsky 1995, 2000), it is not uncommon to encounter multiple types of analyses for the same phenomenon proposed in the literature. A natural question, then, is whether one could evaluate and compare syntactic proposals from a quantitative point of view. In this paper, we show how an evaluation measure inspired by the minimum description length principle (Rissa-nen 1978) can be used to compare accounts of syntactic phenomena implemented as minimalist grammars (Stabler 1997), and how argu-ments for and against this kind of analysis translate into quantitative differences.

Relative clauses as a benchmark for Minimalist parking

Graf T., Monette J., Zhang C.

Journal of Language Modelling

2017

Vol. 5, No. 1

57--106

Minimalist grammars have been used recently in a series of papers to explain well-known contrasts in human sentence processing in terms of subtle structural differences. These proposals combine a top-down parser with complexity metrics that relate parsing difficulty to memory usage. So far, though, there has been no large-scale exploration of the space of viable metrics. Building on this earlier work, we compare the ability of 1,600 metrics to derive several processing effects observed with relative clauses, many of which have been proven difficult to unify. We show that among those 1,600 candidates, a few metrics (and only a few) can provide a unified account of all these contrasts. This is a welcome result for two reasons: First, it provides a novel account of extensively studied psycholinguistic data. Second, it significantly limits the number of viable metrics that may be applied to other phenomena, thus reducing theoretical indeterminacy.
