Probing the discourses of climate change (CC)
What can automatic text mining reveal about CC communication?
In a series of interrelated student projects, spanning across several seminars and research modules in 2020/2021, we apply text mining methods to a variety of text corpora (some of which we built ourselves). The overarching goal is to identify patterns, opinions and arguments brought forward in different CC discourses.
NEW (June 2021): On June 25, Prof. Stede will give an invited talk "Framing Climate Change: A Computational Approach" at the NLDB conference.
NEW (May 2021): A video that introduces five of our recent student projects (largely in German), targeting the general public, is available at the online "Potsdamer Tag der Wissenschaften" here.
- GerCCT: 12.000 pairs of German Climate Change Tweets, collected at DRL (see Schäfer/Stede 2020 below)
- NatSciCC: 490 editorials from Nature and Science (1966-2015), manually annotated by Hulme et al. 2018 for thematic framing categories. We built a digital version of the corpus.
- NYTAC: New York Times Annotated Corpus. We identified 10.000 articles related to CC.
- CMV-CC: A CC subset of the "Change My View" subreddit corpus compiled by Webis.
- Framing in NatSciCC: Following up on the work of Hulme et al. 2018, we analyze the linguistics of framing in editorials.
- Classifying the NatSciCC texts: Focusing on the problem of imbalanced data, we aim at automatically reconstructing the topic frame annotations by Hulme et al. 2018 (see Bracke 2020 below).
- Tracking CC in NYTAC: We use unsupervised methods to detect patterns in CC reporting in The New York Times (1987-2007).
- Argumentation in Twitter exchanges: We study various subtaks of argumentation mining on the GerCCT corpus.
- News headlines: We searched the archives of German newspapers for climate change articles, collected their headlines and study trends of term usage
- Glossary: In collaboration with Digitales Wörterbuch der Deutschen Sprache, we build a linguistically-oriented glossary of German climate change terms.
