Character-based Neural Semantic Parsing

Abstract

I quite enjoyed my time as a PhD-student. This is largely due to all the people I spent time with over the past 4 years. I feel like I owe all of you a sincere thank you, so here goes.First, and most importantly, I'd like to thank Johan for hiring me and guiding me through the project. You gave me a lot of freedom, which I appreciated, but also gently pushed me back on track if needed. Let the record show that some of the more creative ideas in this thesis were yours. I really enjoyed working together, but also have great memories of the soccer matches and parties you hosted (despite your kids always beating me at chess).Antonio, asking you to be my co-supervisor was probably one of the best decisions I made during the PhD. Your knowledge about neural networks, eye for detail and pressing for experimental rigour made this a much better thesis. Above all, you were simply very pleasant to work with. Thanks a lot! Lasha, though not as an official supervisor, you helped me a lot during these 4 years (even co-authoring two of the papers) and I appreciate that.There is no one else out there who can be so clever, funny and confusing at the same time. I will surely always remember the "compensation cake".Of course, thanks to the reading committee, Michael Biehl, Anette Frank and Mirella Lapata, for reading and accepting my thesis. You provided me with a lot of useful feedback, which definitely improved the thesis.

Constructing a cross-document event coreference corpus for Dutch

“…Note that only the heads of the clusters are processed, which greatly improves the efficiency of the algorithm. As an additional step, before the sieves are passed through, each cluster is parsed using the Dutch Alpino parser (van Noord, 2006), and assigned a set of cluster properties such as number, gender, and entity type. No two clusters can be merged when there is a critical mismatch of these properties.…”

“…Head Matching Mentions are parsed using the Alpino dependency parser (van Noord, 2006) and their syntactic head is determined. Two mentions with the same syntactic head are assigned to the same coreferential chain when there is no conflict in their respective modifiers.…”

“…A table detailing each individual feature that was used can be found in the appendix. Syntactic, semantic and morphological features were extracted using the Dutch dependency parser Alpino (van Noord, 2006).…”
