NL Seminar-UNDERSTANDING THE WORLD'S COMPOSITIONAL CONCEPTS

Speaker: Marius Pasca, Google

Talk Title: UNDERSTANDING THE WORLD'S COMPOSITIONAL CONCEPTS

Series: Natural Language Seminar

Abstract: Compositional topics ("Swiss passport", "German grammar") of interest to Web users may be available as entries within structured knowledge resources. But such topics are not necessarily connected to, let alone represented in relation to, entries of the constituent topics ("Switzerland" and "Passport", or "German language" and "Grammar") from which their approximate meaning could be aggregated. Web documents - more precisely, encyclopedic articles - and Web search queries are shown to be useful in complementary tasks relevant to understanding compositional topics. The tasks are the decomposition of potentially compositional topics into zero, one or more constituent topics; and the interpretation of the role ("issued by", "of") played by constituents ("Swiss", "German") within ambiguous compositional phrases that might refer to compositional topics.





Biography: Marius Pasca is a research scientist at Google in Mountain View, California. Current research interests include factual information extraction from unstructured text within documents and queries, and its applications to Web search.
