I'm Zahra Sarabi, a PhD candidate at the University of North Texas. I am a member of the Human Intelligence and Language Technologies laboratory in the Computer Science department at University of North Texas. My advisor is Dr. Eduardo Blanco.
In my spare time I serve as vice president of UNT Women in Computing.

My research interests lie in the areas of natural language processing and machine learning. I work to make computers understand and generate natural language better. I mainly work on Negation. In my research I am developing a system that can understand Negation in positive terms with applications ranging from machine translation to textual entailment and commonsense reasoning. More specifically, I am identifying the (usually few) tokens that are intended to be negated within a negated statement, and plan to rewrite them with their positive counterparts.

Past Work

Befor coming to UNT, I was working on Persian language processing. We designed and implemented an NLP Toolkit for Persian using JAVA (ParsiPardaz). This task was done as part of a larger project focused on designing a question answering system for the Persian language. The toolkit includes a Tokenizer, Lemmatizer, POS tagger and Dependency Parser. Results were published in [5]. An online version of ParsiPardaz toolkit is available: ParsiPardaz
