Let's go to IEICE Workshops!

Demonstrating the Incremental Interaction Manager in an End-to-end “lets Go!” Dialogue System

The Incremental Interaction Manager supports the use of incremental speech recognition with conventional turn-based dialogue managers. We demonstrate its use in a complete statistical dialogue system in the “Lets Go” bus information domain. Our demonstration is two-fold. First, the user is able to call the system and have a complete dialogue. They are then able to inspect their own call using a...

IEICE Transactions on Communications: Editor's Message

I am pleased to take on the job of Editor-in-Chief for the IEICE Transactions on Communications. The IEICE Transactions on Communications is now in excellent shape. We received more than 1,200 original submissions in 2009, slight increase over 2008. More than 80% submissions were from outside Japan, including Korea, China and USA. Acceptance ratio for papers was less than 30%. On behalf of a co...

Constructability of Trip-lets

A trip-let is an object as shown on the cover of Hofstadter’s book Gödel, Escher, Bach: a solid, threedimensional object that, when viewed from three orthogonal directions, shows three different letters. In this paper we consider two problems related to the construction of such objects for a given set of three letters. First, we want to know whether the silhouettes of the object correspond to t...

On Desugaring Polymorphic Lets

Existing type literature has conflicting views on desugaring polymorphic lets to lambda terms. The conflict arises because, in certain cases, desugaring does not preserve typing. We describe a transformation of polymorphic lets to monomorphic lets such that, when the monomorphic lets are desugared, the typing is preserved. Our transformation requires no changes to either term or type syntax. Th...
