In this month's newsletter, the LDC would like to announce the availability of a new LDC Online service and the release of three new corpora.
------------------------------------------------------------------------
The LDC is pleased to announce that an improved LDC Online service is now available. LDC Online can be accessed at the following url:
https://online.ldc.upenn.edu/login.html
Organizations that hold 2005 Membership in the LDC will be able to perform text searches on our entire English Gigaword corpus. This corpus is a comprehensive archive of newswire text data that has been acquired over several years by the LDC. Current members will also be able to access the American English Spoken Lexicon (AESL). AESL contains pronunciations in individual audio files for more than 50,000 of the most common words in English
Even if your organization is not a current member, you can access LDC Online through a guest account. As a guest, an LDC online user will be able to access the American English Spoken Lexicon.
We will offer periodic updates to LDC Online to include new corpora and search functions. Please check in with us often as we anticipate this will be an exciting offering.

ACE 2004 Multilingual Training Corpus
Sites were evaluated on system performance in six areas: Entity Detection and Recognition (EDR), Entity Mention Detection (EMD), EDR Co-reference, Relation Detection and Recognition (RDR), Relation Mention Detection (RMD), and RDR given reference entities. All tasks were evaluated in three languages: English, Chinese and Arabic.ACE 2004 Multilingual Training Corpus is distributed on one CD-ROM.
2005 Subscription Members will automatically receive two copies of this corpus. 2005 Standard Members may request a copy as part of their 16 free membership corpora. Nonmembers may license this data for US$3000.

Chinese News Translation Text Part 1
The source Chinese text and its English translations were selected and translated in different LDC projects. A total of about 474K Chinese characters were selected from two sources, namely Xinhua and AFP, and translation services were provided by seven translation agencies. Each Chinese news story was translated once. Chinese News Translation Text Part 1 is distributed via ftp.
2005 Subscription Members will automatically receive two copies of this corpus on CD-ROM. 2005 Standard Members may request a copy as part of their 16 free membership corpora. Nonmembers may license this data for US$1500.

Dr. Dan Gildea from University of Rochester will be giving a talk on his recent work on March 18th, Noon.
Syntactic Structure and Statistical Machine Translation
Given that statistical methods have revolutionized both
natural language parsing and machine translation, it may
seem surprising that most current statistically-based
translation systems make no use of syntactic structure.
I will describe work on models of translation that aim
to fill this gap, presenting results for models that
make use of syntactic information provided for one or
both languages, as well as models that infer structure
directly from parallel bilingual text. I will also
describe the use of syntactic information for the
automatic evaluation of machine-produced translations.
