Sanda Harabagiu's Publications

Selected Recent Publications by Sanda Harabagiu
Below I include links to some of my recent papers, many of which were written with co-authors, in reverse chronological order. Most of my research has been in the general areas of natural language processing(NLP) and in parallel processing(PP). Specifically, I am concerned with problems in textual Question-Answering, Information Extraction, and Reference Resolution, Text Summarization and Discourse and Dialog Processing. In general, I am interested in many aspects of the integrations of syntactic, semantic and pragmatic knowledge for understanding texts and conversations and for building applications that enable better interactions between humans and computers.

I have annotated my papers according to which of these fields they correspond to.

NLP: Natural Language Processing

SE: Search Engines

PP: Parallel Processing
