Two Alternatives for a Conference Rotation SchemeBasic Idea: every part of the world is assigned to a particular region

that ACL will visit every third year

The vertical approach (eg. IJCAI Conferences)

The horizontal approach (a “cool“ idea)

A New Three-Year Rotation Scheme:The horizontal partitioning approach

Creating two new Chapters: The Arctic Chapter of the ACL: AACL (Double ACL) The Antarctic Chapter of the ACL: AAACL (Triple ACL)

Y2K: The Killer App for NLP (see Marcus 1997)

Y2K Y TO K B2B B TO B(Business-to-Business)

$200 billion spent worldwide to address the Y2K problem

45 international conferences dealing with the Y2K problem

BUT: The Y2K problem is still open.

WHY? 2 [tu:] is a homophone with{to, too, two} as a homophonic set

Y2K Y TWO K B2B B TWO B

Y2K: The Killer App for NLP

Two Y2K problems (syntactic ambiguity)

Two parse trees:

Y 2 K11 Y 2 K22

11 Numerical Y2K problem: arises from early space-saving method

2000

Y 2000 ‘Y‘ to ‘K‘

22 Non-Numerical Y2K problem: arises from a major spelling reform

The Seriousness of the Non-NumericalY2K Bug

The numerical Y2K bug hype was greatly overblown

But: The non-numerical Y2K bug can cause serious economic and social harm

Extensive use of date expressions (MUC, Verbmobil)

IT that supports global capital flow

payrolls

small business inventories

is highly vulnerable.

Embedded IT systems in: aviation

health care

telecommunications

are unable to deliver services in a normal manner.

• Synchronous tree adjoining grammars

• Combinatory categorial grammar with typed feature unification

• HPSG grammar compiled to a lexicalized tree adjoining grammar

• CFG approximation of a probabilistic LFG parser

• Bidirectional cascade of chunk parsers

Status of ACL's Y2K Date Change Project

We have now implemented all changes to all programs and all data to reflect the new date standards:

Mondak, Tuesdak, Wednesdak, Thursdak, Fridak, Saturdak, Sundak,

Microsoft has announced a solution for the the non-numerical Y2k problem. However a Microsoft spokesman said that it will relesead not before 2004.

Thus, ACL has a key competitive advantage using its FST solution and bringing it to market right now.

ACL's non-numerical Y2K Date Change Project

We have gone through

every line of codein every program in every system.

We have analyzed

all databases, all knowledge bases all data files all backups all historic archives.

and modified all data with ACL's non-numerical Y2K technology to reflect the change.

We are proud to report that we have completed the date change mission.

A TV Ad Campaign for ACL Membership Growth

Language Technology Increases Employee Job Satisfaction!

TV ad campaign is less efficient than an ACL song that makes it onto the top international music

charts

What type of song? What music style?

Folk music (too old-fashioned)

Jazz (too sophisticated)

Post-Punk (too loud)

Techno (no underlying message)

Rap/Hip-Hop (Street poetry)
