Ambiguity and the design of language

The general objective of this workshop is to bring together several researchers working within different fields, such as experimental linguistics, artificial intelligence, categorial grammar, theoretical linguistics, sign languages and complex systems, in order to determine the importance of ambiguity in defining the design of language.

The central questions to be discussed in this workshop will be:
 
1. Are there any optimality considerations, related to the structure of lexicon or to general conditions on efficient communication, that favor the emergence of ambiguity?

2. What is the role of ambiguity in the origin of complex syntax?

3. What are the types of ambiguity displayed in sign languages?

4. At what grammatical level of representation are ambiguities resolved?

5. How is ambiguity treated in highly formalized grammatical
systems, such as Montague grammar and categorial grammar?

6. What is the role of prosody and gesture in avoiding ambiguity?
