In this seminar we focus on learning how to carry out linguistic research, in this case specifically cross-linguistic research using (parallel) corpora. Through several case-studies, we work on 1) digesting scientific literature to uncover the state-of-the-art on a particular topic; 2) formulating a relevant research question; 3) studying the right method to answer the research question; 4) carrying out the research, in this case searching and annotating corpora; and 5) presenting the results in both oral and written format. Over the course of the seminar we will work in group-form with several corpora and on several topics, including verbal lexical semantics (motion, perception, ingestion, communication, placement), Komolgorov complexity, pronouns, and question marking. For the final assessment, each student works further on one of the case-studies or on their own research question, presents their work orally and writes a conference abstract.
