Abstract: “At the Intersection of Data Science and Language”
Data science holds the promise to solve many of society’s most pressing challenges. But much of the data necessary to solve problems is locked within volumes of text and speech on the web.  Thus, in many cases, data science can only succeed if paired with natural language processing. In this talk, I will discuss the data science initiative at Columbia University and research within its New Media Center, where we investigate the analysis of news, Twitter, online discussion and as well as texts coming from digital humanities, scientific and other disciplines. I will describe research projects that draw from scientific journals, from historical sources, from online media, and from novels.

Abstract: “Bottom-Up Semantics”
Advances in statistical and machine learning approaches to natural-language analysis have yielded a wealth of methods and applications in information retrieval, speech recognition, machine translation, and information extraction. Yet, even as we enjoy these advances, we recognize that our successes are to a large extent the result of clever exploitation of redundancy in language structure and use, allowing our algorithms to eke out a few useful bits that we can put to work in applications. By focusing on applications that extract a limited amount of information from the text, finer structures such as word order or syntactic structure could be largely ignored in information retrieval or speech recognition. However, by leaving out those finer details, our language-processing systems have been stuck in an "idiot savant" stage where they can find everything but cannot understand anything. Our main language processing challenge is to create robust, accurate, efficient methods that learn to understand the main entities and concepts discussed in any text, and the main claims made. These will enable our systems to answer questions more precisely, to verify and update knowledge bases, and to trace arguments for and against claims throughout the written record. I will argue with examples from my team’s research that we need deeper levels of linguistic analysis to do this. But I will also argue that it is possible to do much that is useful even with our very partial understanding of linguistic and computational semantics, by taking (again) advantage of distributional regularities and redundancy in large text collections to learn effective analysis and understanding rules.

Professor Richard Kenway, Vice Principal for High Performance Computing, and Professor Chris Williams, Director of the CDT in Data Science, from the University of Edinburgh will also give short presentations.

In 1985 she received a National Science Foundation Presidential Young Investigator Award, in 1991 she received a National  Science Foundation Faculty Award for Women, in 1994 she was selected as a AAAI Fellow, in 2003 she was elected as an ACM Fellow, and in 2012 she was selected as one of the founding Fellows of the Association for Computational Linguistics. In 2010, she received the Anita Borg Institute Women of Vision Award in Innovation for her work on text summarization. McKeown is also quite active nationally. She has served as President, Vice President and Secretary-Treasurer of the Association of Computational. She also served as a board member of the Computing Research Association and as secretary of the board.
