About Me


My name is Sara Rosenthal (My maiden name is Sara Stolbach). I am a sixth year PhD student in the NLP Group. My Advisor is Kathy McKeown.

I completed my Masters in Computer Science at Columbia University on the Machine Learning Track in Spring 2008. I recieved my BS in Computer Science with a minor in Math at Ramapo College of New Jersey. I interned at Google on the Sentiment Analysis Team in New York City in Summer 2007 and in the Services Group at IBM Research in Summer 2013. Prior to pursuing my Master's degree I worked at RustyBrick as a Web Programmer.

I got married on August 2, 2009 to David Rosenthal (picture of us from our wedding on the left). I have a 3 year old son, Avraham, and a baby daughter, Malky, who was born on my birthday! (picture on the left)

Research Interests


My main interests lie in applying Natural Language Processing to study Sociolinguistics in Social Media. My current research in this area is funded under the DARPA deft project (previously funded under IARPA SCIL project) where I work on automatically detecting influence in online conversations. This work involves identifying opinion, claims, persuasion, and agreement. Visit my publications page to see several related publications. I successfully proposed my Thesis in November 2012.

I am co-organizing Semeval 2014 Task 9: Sentiment Analysis in Twitter, which builds off the prior years task, https://www.cs.york.ac.uk/semeval-2013/task2.

I previously worked on GALE, a Question/Answering System involving Machine Translation where I maintained the pipeline and various services. During my undergraduate degree I did research in using Rule Based Expert Systems for an Intelligent Tutor System at Ramapo College with Dr. Amruth Kumar
