My areas of research are in discourse, semantics, pragmatics (particularly figurative language and sentiment analysis) and summarization. Please contact me if you are interested in a BA or MA thesis in those topics. Current ideas for thesis topics and areas include but are not limited to the following:
Popularity Prediction for Social Media Posts (MA/BA).
Modelling the Influence of Information Retrieval on Timeline Summarization (MA).Timeline Summarization generates dated timelines for long-running social events such as wars, disease outbreaks or financial crises. In contrast to standard single or multidocument timeline summarization, it summarizes hundreds of documents and is therefore dependent on good IR processes before summarization. Current research neglects this aspect; in particular, it is unclear whether performance differences for summarization systems hold up across differing prior IR models. This project will explore the combination of different IR and different timeline summarization models to explore this question.
Models for comparative anaphora and bridging (MA/BA).In both comparative and bridging anaphora, anaphora and antecedent are not coreferent. In comparative anaphora, anaphor and antecedent are mutually exclusive sets (Donald Trump --- other presidents) whereas in bridging the anaphor is associated by a world knowledge or lexical relation to the antecedent (a house --- the door). For both problems, automatic resolution results are substantially lower than for coreference resolution. Several subjects for the automatic modelling of these problems are possible as thesis topics:
- Building a minimalistic classifier for comparative/bridging anaphora. Training data for these problems is limited and often domain-specific. It is therefore useful to explore a domain-independent general rule-based classifier for these problems.
- Word embeddings for comparative/bridging anaphora resolution.
- An integrated, joint approach to coreference and bridging resolution.
Several projects on offensive language identification.In addition, my PostDoc Michael Wiegand offers several projects on offensive language identification. The descriptions can be found under https://www.cl.uni-heidelberg.de/~wiegand/thesisTopics.txt
If you do not find anything you like, but still would like something in the area of summarization, sentiment or discourse please contact me.
