Research Interests
- generation and summarization
- discourse coherence and information structure
My PhD is about sentence fusion, that is about how to generate a
single novel sentence from a set of related sentences. The approach
I undertake relies on dependency structures of sentences and,
similar to existing ones, proceeds in two steps: (1) a new tree is
generated; (2) this tree is linearized. It is not abstractive
summarization yet but can be considered a first step towards it.
The main goal of my PhD research is to find a way to generate
grammatical and readable sentences since this is what the existing
approaches have reportedly had trouble with. If you are interested
in the details, please have a look at the papers. The recent EMNLP
paper is about how a new dependency tree is generated by
compression from a graph of aligned words. The linearization
algorithm is described in the ACL07 paper. The INLG paper explains
how the method can be applied to sentence compression and presents
the results on English data.
Soon, I am going to put online the code and the data so that the
experiments can be replicated.
Other topics I am interested in are unsupervized and language
independent methods in NLP and, on the more linguistic side,
cognitive and functional linguistics.

About Me
Before coming to EML, I studied at school and at University in St.Petersburg (BA in
Linguistics), for the MA degree in CL in Tübingen (under
supervision of Prof.Dr. Erhard Hinrichs and Dr. Sandra
Kübler). Currently, I am a PhD student of Prof.Dr. Elke Teich at TU Darmstadt.
In case you wonder what the best time to go to Petersburg is, I
suggest June, late August-early September, and January. If you have to
choose between Heidelberg and Tübingen, I would recommend visiting
Heidelberg. Even if this information is of no use for you, well, you
still have learned something about me.

Personal Interests
I am pretty much
interested in everything, in particular, good books, good music, good (motion)
pictures and opera. It is tempting to write more, so I might put a
list with exact names and titles of what I consider "good".
