Natural language processing, focusing on meaning and inference, representations for textual information and applied methods for exploring it.
ABOUT MY WORK
My research area is applied semantic processing, mostly based on data driven machine learning methods. My group, together with colleagues established the textual entailment recognition paradigm.
We are investigating various aspects of natural language inference, including detecting the semantics structure of sentences and identifying the sematnive relationships between words and phrases.
More recently, we have been focusing on the challenge of extracting and representing the consolidated information expressed in multiple texts and in developing novel interactive summarization approaches, which allow people to explore such information.
