about me

I am a PhD candidate and research assistant at the Linguistics Department of the University of Potsdam since October 2012. I work in the Theoretical Computational Linguistics group, supervised by Alexander Koller.


current: generating instructions in a situated dialog context

My current research is about the automatic generation of instructions directed to human listeners in a virtual or physical environment. In particular, I have been working on the problem of automatically generating referring expressions for given objects in the environment, which make it easy for human users to identify those objects. To do that, I am using machine learning methods to predict which expressions have a higher chance of being correctly understood by listeners, based on recorded system-human interactions. For collecting data and testing my method I am using the GIVE virtual environment. For more information, you can take a look at my publications.

I work in close collaboration with Martín Villalba and Alexander Koller. Most of my work has been funded by the D6 project titled Structuring Information in Natural Language Generation of the Collaborative Research Center SFB 632 of the German Research Foundation (DFG).


In 2012, as a MSc student at the Computational Linguistics department of Saarland University, I did my Master's thesis on the effects of language complexity on cognitive load and driving performance in a dual-task experiment, under the supervision of Vera Demberg and Asad B. Sayeed. I also worked in a project on word sense disambiguation, supervised by Annemarie Friedrich and Manfred Pinkal.

Before that, as an undergraduate student at the Department of Informatics of the University of Athens, I wrote my thesis on sentiment analysis of product reviews using machine learning methods, supervised by Giorgos Paliouras. I later worked as an external assistant at NCSR Demokritos in the SYNC3 project about identifying sentiment in news blogs.


WS 2013-14: Discourse as a joint activity

In the winter semester of 2013-14, I co-taught a pragmatics seminar titled Discourse as a joint activity jointly with my colleague and office mate Martín Villalba. Our main textbook was Herbert H. Clark's Using Language, which describes human discourse, and in particular conversation, as a joint activity, in which the speaker and addressee coordinate their actions based on their mutual belief about what consists common ground between them, in order to achieve their shared and/or private communicative goals.
