We describe a scalable architecture, particularly well-suited to cloud-based computing, which can be used for Web-deployment of spoken dialogue systems. In common with similar platforms, like WAMI and the Nuance Mobile Developer Platform, we use a client/server approach in which speech recognition is carried out on the server side; our architecture,(More)
We present a distributed garbage collection algorithm that eventually collects all cycles in an open network. As with recent reference counting algorithms, it explicitly maintain the distributed inverse reference graph (i.e., each object maintains a list of sites known to have references to it). We show that a modiied depth-rst traversal of this inverse(More)

For Web services to fulfil their promise in truly heterogeneous environments, the different base operations being included in Web services will need to appear in multiple Web Services with different names as well as different authorization and authentication mechanisms, different service level agreements, and even different formats. We describe service(More)
We describe an extension of regular expresions using arbitrary all-groups and numeric exponents (as in W3C XML Schema). We are able to provide polynomial-time algorithms for testing UPA and content model subsumption for these extended regular expressions. The algorithm handles numeric exponents (as opposed to the Kleene operators of traditional regular(More)

We describe a version of the CALL-SLT spoken conversation partner adapted for use on a mobile device. The system allows beginner/intermediate language students to practise interactive spoken language skills, using a version of MIT's " translation game " concept: the machine prompts using an abstract description of what the student is supposed to say, and(More)
