3 American Zone European-African Zone Asian-Pacific Zone Rotation Scheme for International ACL Conferences ACL

4 American Zone European-African Zone Asian-Pacific Zone Montreal 1998 Madrid 1997 Maryland 1999 Saarbrücken 2000 COLING Conferences ACL Conferences EACL Conferences Hong Kong 2000 Rotation Scheme for CL Conferences Toulouse 2001 Milwaukee 2002 ? Edmonton 2002 ? Taipei 2002

5 Two Alternatives for a Conference Rotation Scheme Basic Idea: every part of the world is assigned to a particular region that ACL will visit every third year American Zone European- African Zone Asian- Pacific Zone The vertical approach (eg. IJCAI Conferences) Arctic Zone Antarctic Zone Central Zone The horizontal approach (a “cool“ idea)

6 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) Arctic Region 2003 CL for the Snow iMac Central Region Antarctic Region 2002 CL for LINUX 2001 CL for Windows

8 Y2K: The Killer App for NLP (see Marcus 1997) Y2K  Y TO KB2B  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

9 Y2K: The Killer App for NLP Two Y2K problems (syntactic ambiguity) Two parse trees: Y 2 K Numerical Y2K problem: arises from early space-saving method 2000 Y 2000 ‘Y‘ to ‘K‘ 2 2 Non-Numerical Y2K problem:arises from a major spelling reform

10 The Seriousness of the Non-Numerical Y2K 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.

11 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 Various Approaches to the Non-Numerical Y2K Problem

12 ACL‘s FST Solution for the Non-Numerical Y2K Problem y:k  y:  S 1 Simple Very Efficient: O(n) Java Applet Finite-State Transducer Single State Two Transitions

13 Monday, 3 May 04 Mondak, 3 Mak 2004 Monday, 3 May 04 An example of the combined Y2K Problem

14 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 Thus, ACL has a key competitive advantage using its FST solution and bringing it to market right now. Januark, Februark, March, April, Mak, June, Julk, August, September, October, November, December

15 ACL's non-numerical Y2K Date Change Project We have gone through every line of code in 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.

24 A TV Ad Campaign for ACL Membership Growth Language Technology Increases Employee Job Satisfaction!

25  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) The Optimal PR Compaign for ACL

Chorus

27 The ACL Rap 2. Part BNC, DCI and DRS XLE, RST and TMS QLF, VIT and DCG FSA, CLR and CUG CLE, FUF and CCG ILL, SMT and TAG ALE, MGU and XML BDI, CSP and XOL Acronyms, are for the machine, When they know what we mean, It‘s just sensational, That's why there's ACL, So come and take our word for it, All those acronyms will be sentenced to life.
