Aims and motivation

The aim of this course is to introduce students to the emerging field of the visualization of linguistic information (LingVis) which combines techniques developed in the fields of Information Visualization (InfoVis) and Visual Analytics with methodology and analyses from theoretical and computational linguistics. As a specialized subfield of information visualization, the visualization of language continues to face particular challenges: Language data is complex, only partly structured and, as with todays language resources, comes in large quantities. The overall challenge lies in breaking down the multidimensionality into intuitive visual variables that enable an at-a-glance overview of the data and the patterns underlying it. In this course, we aim to introduce students to the basic principles of InfoVis and present concrete use cases of LingVis in both synchronic and diachronic dimensions. A part of the course will include hands-on sessions in which students can experiment with pre-prepared data sets and LingVis software in order to investigate how complex linguistic questions can profit from visual analysis.

Expected level and prerequisites: Introductory. Basic knowledge of linguistics is required. Elementary programming experience will be helpful but is not a priori required.
