In memoriam: Christopher Cieri 1963-2023
With deep sadness, LDC announces the passing of Christopher Cieri, our
Executive Director. Chris led the Consortium for over 25 years,
guiding its evolution from a small data repository and research hub to
a prominent global data center.

An accomplished linguist, computer scientist, and a well-read
humanist, Chris embodied the best qualities for executing the wide
range of duties demanded by his leadership role. He was a valued
colleague and friend and will be sorely missed.

All are welcome to visit our remembrance page for Chris.

New publications:
Penn Korean Universal Dependency Treebank contains 5010 sentences and
132,041 tokens annotated in dependency format under the Universal
Dependencies framework. It is a conversion of Korean Treebank
Annotations Version 2.0 (LDC2006T09), which was produced in
constituency format.

The source text is newswire stories from LDC’s Korean Press Agency
collection contained in Korean Newswire (LDC2000T45). Sentences were
automatically converted for dependency annotation; the output was
manually checked. The corpus contains 112 files in CoNLL-U format, the
Universal Dependencies standard, with a mapping to their counterpart
in LDC2006T09.

2023 members can access this corpus through their LDC accounts.

*
DEFT English Light and Rich ERE Annotation was developed by LDC and
consists of 1190 English discussion forum, newswire, and proxy
documents annotated for entities, relations, and events (ERE). Light
ERE annotation labels entity mentions for the target set of entity,
relation, and event types between and among those entities, including
coreference. Rich ERE annotation expands types and tagging in the
entities, relations, and events annotation tasks and replaces strict
event coreference with a more loosely defined event hopper annotation.

902 documents were annotated following Light ERE annotation
guidelines. 288 documents were labeled with Rich ERE annotation in a
second pass after being annotated for Light ERE. The source data
consists of English discussion forum web text collected by LDC for the
DARPA BOLT program and contained in BOLT English Discussion Forums
(LDC2017T11); newswire documents published in various data sets
released in the TAC KBP project (Text Analysis Conference Knowledge
Base Population); and proxy documents intended to mimic government
analysis reports of newswire content published in DEFT Narrative Text
(LDC2016T07).
