 Syntactic and Semantic Complexity in Natural Language Processing Systems

	Workshop to be held in conjunction with ANLP-NAACL2000

		 Date: Sunday, April 30 2000

			Seattle, Washington.

The last decade has seen an explosion in the work done in the development
of robust natural language processing systems. A common methodology used in
building these systems has been to analyze a sample of the data available
(either manually, or automatically for training statistical systems), build
statistical/heuristical schemas based upon the analysis, and test the system 
on a blind sample of the data. Due to this commonly used paradigm, an 
important area of research that has not been given the attention it deserves is 
the estimation of syntactic and semantic complexity faced by these systems in 
the tasks they perform.

At the AAAI 1999 Fall Symposium on Question Answering Systems, the problem of 
semantic complexity, a topic of a 90 minutes panel, motivated a lot of interest 
and discussion. To continue the investigation of this important issue, in this 
workshop, we will address the question of complexity as it pertains to the 
syntax and semantics of natural language. In particular, the workshop will 
seek to address the following areas:

1) How can we model syntactic and semantic complexity for formal models of 
 natural language?
2) How does complexity impact acquisition of semantic and conceptual
3) How does syntactic and semantic complexity impact document classification in 
 information and text retrieval tasks?
4) How do statistical clustering approaches compare to knowledge-based
 approaches at partitioning and quantifying the semantic space in a document
5) Concerning NLP systems that are deployed in the field, how can we quantify
 the information extraction task and QA task in ways similar to what is
 currently done with IR tasks and algorithms?
6) How does the estimation of syntactic and semantic complexity impact the 
 evaluation of such systems?
7) Can syntactic and semantic complexity coupled with a history of the past 
 performance of a system be used to predict future performance of the system 
 on a different data set?

The workshop invites short papers, full-length papers, proposals for panel
discussions, and position statements that deal with any aspect of syntactic 
and/or semantic complexity of NLP systems. In particular, the workshop is 
interested in addressing the following topics:
 - estimation of the syntactic and semantic complexity of specific NLP tasks
 - semantic complexity and world knowledge
 - role of syntactic and semantic complexity in system design and testing
 - syntactic and semantic complexity and its role in the evaluation of NLP 
 - use of syntactic and semantic complexity as a performance predictor
 - relationship between syntactic and semantic complexity


Paper submissions should consist of either a short paper (2000 words or less,
including references), a position statement (2000 words or less, including
references), or a full paper (5000 words or less, including references). Each 
submission should include a separate title page providing the following 
information: the title, the type of paper (short/position/full), the word 
count, a short abstract, names and affiliations of all the authors, the full 
address of the primary author (or alternate contact person), including phone, 
fax, and email. Proposals for panels should consist of a short (upto 500 
words) description of the proposed panel along with the names of the proposed 

Papers and proposals for panel discussions may be submitted by submitting three 
hard copies or one soft copy (ASCII, or PS) to:
