Students I co-supervise and co-supervised:


2020/12/17: The paper Evaluating data-to-text NLG accuracy by natural language inference by me & Zdeněk kasner has received the INLG 2020 Best Short Paper award!

2020/11/21: Two INLG 2020 papers by Zdeněk Kasner & me are now out on arXiv: Data-to-text generation by iterative text editing and Evaluating data-to-text NLG accuracy by natural language inference.

2020/11/16: The list of accepted papers and a preliminary schedule for the NLG Evaluation Workshop I'm co-organizing at INLG 2020 is now available.

2020/09/29: The Statistical Dialogue Systems course I'm teaching with Vojtěch Hudeček has started its 2020/2021 run.

2020/07/25: We got two papers on neural text-to-speech accepted to Interspeech, both are available on arXiv: Tomáš Nekvinda's One Model, Many Languages: Meta-learning for Multilingual Text-to-Speech and Jan Vainer's SpeedySpeech: Efficient Neural Speech Synthesis.

2020/07/01: Me & Vojtěch started working on a joint project METOD with Agnostix, investigating dialogue management modelling and visualizations, supported by the City of Prague.

2020/05/26: We (Jindřich Libovický, Zdeněk Kasner, Jindřich Helcl & me) took part in the STAPLE/Duolingo translation & paraphrasing WNGT shared task. Our report is now in the ACL anthology.

2020/04/06: Our paper “Fact-based Content Weighting for Evaluating Abstractive Summarisation” (by Xinnuo Xu, me, Jingiy Li, Yannis Konstas & Verena Rieser) was accepted for ACL. You can read the paper in the ACL anthology.

2020/04/01: Our grant project THEaiTRE for automatically generating theatre plays was accepted by the Czech Technical Agency (and actually got the highest ranking of all submissions)! We plan to have a theatre play performed in January 2021, for the 100th anniversary of Karel Čapek's R.U.R.

2020/03/23: Verena Rieser and I were guests at the NLP Highlights podcast, and we talked about data-to-text generation. You can listen to the podcast on Soundcloud.

2020/03/03: I gave a short talk at the Czechbots chatbot meetup. You can find the slides here.
