Workshop: Optimizing (Socio-)linguistic Analysis: Language Variation Suite Toolkit

Time: 04/12/18 1:30pm EST – 3:00pm EST

Venue: Woodburn Hall, 200 (SSRC Grand Hall)

In the format of hands-on session, this workshop will introduce participants to the Language Variation Suite (LVS), a user-friendly interactive web application built in R. LVS provides access to advanced statistical methods and visualization techniques, such as mixed-effects modeling, conditional and random tree analyses, cluster analysis. These advanced methods enable researchers to handle imbalanced data, measure individual and group variation, estimate significance, and rank variables according to their significance.

Workshop: Data Visualization for Corpus Linguistics via Shiny Framework

“The purpose of visualization is insight, not pictures”
(Ben Schneidermen, 1999)

Information visualization affords new opportunities for corpus linguistics. In addition to interpretable data synthesis (Keim et al., 2006), visualization allows researchers to unveil linguistic patterns through data exploration and discovery. Until recently, the full integration of visual analytics into corpus tools was not feasible. For example, web-based corpora (e.g., COCA and BNC) were limited to pre-defined text collections and functionalities, whereas software applications were mainly built for a specific purpose (e.g., AntConc – concordances, TigerSearch – syntactic query). The recent development of Shiny web framework makes it possible to integrate visualization tools into the corpus analysis. Shiny is a reactive system allowing for interactive data analysis and visualization. Built with R, Shiny web framework also provides access to advanced text mining and quantitative algorithms, thus advancing corpus linguistics studies. In this workshop, you will learn the fundamentals of reactive web framework and visual analytics for corpus analysis.

Shiny Web Application – Workshop

“The impact of data scientists’ work depends on how well others can understand their insights to take further actions” (blog)

In this workshop, I will introduce you to the concept of Declarative Reactive Web Frameworks, allowing for interactive user-friendly data visualization and data analytics, particularly Shiny. Shiny is an R package that creates interactive applications for data visualization.

You will learn some Shiny basics: how to build your reactive app and deploy it to the server.

Seminar on ITMS and LVS: Quantitative Methods and Text Mining

The main objective of this workshop is to introduce researchers to user-friendly analytical tools. ITMS and LVS are two web-based tools for visualization and quantitative analysis.  In contrast to existing software programs (e.g., SAS, SPSS, and Tableau), these two applications are built in R and require no installation or programming skills.

This hands-on workshop will provide an overview of available statistical and text-mining techniques in these tools. You will learn how to import csv, text and pdf files, create plots, and run statistical analysis, including conditional trees and random forest tests. You will also learn about natural language pre-processing techniques, such as stopwords removal and stemming. Finally, you will be able to perform topic modeling and cluster analysis.
