Title: Inferring and Exploiting Relational Structure in Large Text Collections
Abstract: The digitization of knowledge and concerted retrospective scanning
projects are making overwhelming amounts of text in diverse domains,
genres, and languages available to readers and researchers. To make
this data useful, our group is working on improving OCR, language
modeling, syntactic analysis, information extraction, and information
retrieval. I will focus in particular on problems of inferring the
relational structure latent in large collections of documents, such as
books, web pages, patent applications, grant proposals, and social
media postings. Which books or passages quote, translate, paraphrase,
and cite each other? This research requires improvements in modeling
translation and other forms of similarity, as well as improvements in
efficiently comparing large numbers of passages. Finally, I will
discuss how passage similarity relations can be used to improve tasks
such as named-entity recognition and syntactic parsing.
Host: John Lafferty
