The workshop aims to bring together researchers from different background to discuss issues concerning language variation and change, especially in the context of language diversity in China. The workshop will take place on June 14-16, 2019 at The University of Chicago Center in Beijing. In addition to the invited research talks on June 14-15, we will also present two research method tutorials on June 16.

This workshop follows the success of the University of Chicago Language Research Forum that took place in March 2017 and March 2018 at the Hong Kong Jockey Club University of Chicago Academic Complex | The University of Chicago Francis and Rose Yuen Campus in Hong Kong.

Methods Tutorials (June 16th)

Dimensionality reduction for linguists: a practical introduction

Linguistic data is often high-dimensional: quantitative analysis is frequently carried out on a handful of features carefully selected for their linguistic relevance which are extracted from a complex signal containing many potentially analyzable features. In light of this property of language, processing linguistic data using dimensionality reduction is an attractive alternative in some cases. Dimensionality reduction methods algorithmically identify informative covariations among the many values of a data set and capture these using a smaller number of variables. Such an approach is “data-driven” rather than researcher-driven and is especially useful when the features for analysis are difficult to choose, extraction of the features is subject to undesirable amounts of inter-annotator variability, or holistic representations of data are required.

In this tutorial, we will focus on application (using the Python programming language) of simple dimensionality reduction methods to linguistic data of several types. We will focus on two methods: principal component analysis, on the one hand, maximizes variance in each successive principal component discovered, and as such is useful for creating lower-dimensional projections of high-dimensional data. We will also cover linear discriminant analysis, a related method which models differences among known categories using a recombination of variables present in the data, yielding a smaller number of linear discriminants whose values are maximally predictive of class membership.

Signal Detection Theory for Syntactic Research
Signal Detection Theory (SDT) provides a framework for modeling how humans make decisions under conditions of uncertainty. In linguistics we often place our experimental participants or language consultants in just those circumstances. And while SDT has seen some application in phonetics and laboratory phonology, it has not really penetrated research practices in syntax and semantics. Yet it holds much potential. It provides a precise means to characterize the latent cognitive variables which we theorize from, like acceptability. And, perhaps more practically, it provides a concrete way of talking about response bias, which is a well-known pitfall in fieldwork settings (e.g., a tendency to always say “yes”).
In this workshop participants will learn the fundamentals of SDT and how the tools of SDT can help out in linguistics. Examples will be drawn from research in sentence processing, experimental syntax and syntactic fieldwork. We will focus on the application of SDT methods to familiar designs in experimental syntax, such as the ratings task. Participants will have the opportunity to gain hands-on experience with descriptive and inferential SDT analyses in the R statistical environment using “off-the-shelf” software packages and code provided by the instructor. 
Familiarity with basic statistical concepts – like the Normal distribution – is recommended.
