Talk Title

: OntoNotes: A Unified Relational Semantic
Representation

Talk

Abstract:
The OntoNotes project is creating a corpus of large-scale
accurate and integrated annotation of multiple levels of the
shallow

semantic structure in text. Such rich integrated
annotation covering m

any levels will allow for richer cross-level
models enabling significa

ntly better automatic semantic analysis.
At the same time it demands a
robust efficient scalable mechanism
for storing and accessing these

complex inter-dependent annotations.
We describe a relational database

representation that captures both
the inter- and intra-layer dependenci

es and provide details of an
object-oriented API for efficient multi-ti

ered access to this data.

The OntoNotes project is funded by DARPA u

nder the GALE program
and is a collaborative effort between BBN Technol

ogies University of
Colorado University of Pennsylvania and Informati

on Sciences
Institute at the University of Southern California.
