In this paper we give an overview of the ILLC-UvA(Institute for Logic, Language and Computation University of Amsterdam) submission to the 7th International Workshop on Spoken Language Translation evaluation campaign. It outlines the architecture and configuration of the novel feature we are introducing: a syntax-based model for source-side reordering via tree transduction. We have concentrated...

After perceiving multi-modal behaviour from a user or agent a conversational agent needs to be able to determine what was intended with that behaviour. Contextual variables play an important role in this process. We discuss the concept of context and its role in interpretation, analysing a number of examples. We show how in these cases contextual variables are needed to disambiguate multi-modal...

The paper we present compares the three systems for program synthesis, namely Adate, an approach through evolutionary computation, the inductive/abductive logic program synthesizer Dialogs-II and the classification learner Atre, capable of simultaneously learning mutually dependent, recursive target predicates. It gives an overview over the functionality of all three systems, and evaluates thei...

In this paper we argue that conversational dialog systems must model a multidimensional space defined by syntactico-semantic, circumstantial, and interactional dimensions. We take as a testcase the interpretation of a very simple query type within a conversational navigation system that we have implemented. We outline the decision logic this system follows in interpreting next-turn and numbered...

Argumentation has proved a useful tool in defining formal semantics for assumption-based reasoning by viewing a proof as a process in which proponents and opponents attack each others arguments by undercuts (attack to an argument’s premise) and rebuts (attack to an argument’s conclusion). In this paper, we formulate a variety of notions of attack for extended logic programs from combinations of...

Recently, virtual personal assistant (VPA) applications have been employed in mobile devices, which provide a natural and convenient interface between human and machines. As the VPA services become popular, consumers demand for a wider service than their scope, so the rapid development becomes more important. This paper introduces a dialog act modeling approach for VPA applications, which is an...

Situated dialogue corpora are invaluable resources for understanding the complex relationships among language, perception, and action. Accomplishing shared goals in the real world can often only be achieved via dynamic negotiation processes based on the interactants’ common ground. In this paper, we investigate ways of systematically capturing structural dialogue phenomena in situated goal-dire...
