Alles nur Show? Ein automatischer Vergleich von Nachrichten vor der Bundestagswahl mit dem Koalitionsvertrag mittels Natural Language Processing

Objective

The topic is to analyze the coalition agreement (e.g., [0][1]) using Natural Language Processing (NLP) methods. This can involve applying or developing methods to identify the most surprising statements in the text (e.g., text classification for surprise detection, see [2]). Additionally, the goal of the thesis could be to compare which topics and statements, previously mentioned in news articles before the federal election, made it into the coalition agreement and which ones did not. Those that made it into the agreement should be examined in greater detail. For instance, the sources of the news articles that covered these statements before the election can be revealed. The thesis may also examine changes between the parties’ pre-election statements and what was ultimately included in the coalition agreement. Ideas of the student can also be taken into account.

It is expected that the student will submit the work as a joint scientific publication with the supervisor at a later stage. The core tasks include processing the data (e.g., with Python) and applying and evaluating methods for automatic sentence comparison (e.g., SentenceBERT, ABCNN [3], BM25).
