A long line of research in Natural Language Processing (NLP),
including our own, has addressed the task of identifying and
extracting information about opinions with the goal of determining
what people (and other entities) are thinking or feeling.  In this
talk, I'll present new research on argument mining, a relatively new
area of study in NLP that focuses less on extracting from text WHAT
people think or feel, but rather analyzing argumentative text to
understand WHY they do so.

Specifically, I will first present some of our new research on the
automatic analysis of informal, user-generated arguments in which we
aim to expose the intended underlying structure of the argument.
Next, we will examine the arguments on a public debate forum to
determine what makes one argument more convincing than another.  In
particular, recent studies in NLP have provided empirical evidence
that the language of the debaters and their patterns of interaction
play a key role in changing the mind of a reader/listener. On the
other hand, research in psychology has shown that prior beliefs can
affect our interpretation of an argument.  Using debate forum data, I
will present the results of our work to determine the relative roles
of language use vs. prior beliefs in the creation of persuasive
argumentative text.


Claire Cardie is the John C. Ford Chaired Professor of Engineering in
the Departments of Computer Science and Information Science at Cornell
University. She was the founding Chair of Cornell's Information
Science Department.  Cardie has a B.S. in Computer Science from Yale,
and M.S. and Ph.D. degrees in Computer Science from the University of
Massachusetts. She has worked in the area of Natural Language
Processing (NLP) for longer than she would like to admit on topics
ranging from information extraction, text summarization and noun
phrase coreference resolution to the the automatic analysis of
opinions, sentiment and deception in text and was selected as a Fellow
of the Association for Computational Linguistics in 2015.  She has
served on the executive committee of the Association for Computational
Linguistics (ACL), the executive council of AAAI, and twice as
secretary of the North American chapter of the ACL (NAACL).  Cardie
was also Program Chair for EMNLP 1997, CoNLL 2000, and the joint
ACL/COLING conference in 2006 and is very happy to have recently
completed a successful stint as General Chair for ACL 2108.
