Non-instructional linguistic communication with virtual actors
In this paper, we explore a new paradigm for natural language communication with autonomous agents. While the dominant paradigm is to use natural language instructions from which the agent behaviour is generated, we investigate how natural language input can influence a pre-existing planbased behaviour, by interfering with the various types of sub-goals in such a plan. Using as a testbed a fully-implemented interactive storytelling application based on virtual actors, we identify various forms of communicative actions and how these can influence actors' behaviours. We report early results from the use of a speech processing system, used within the storytelling application to influence the behaviour of the artificial actors
Message-Passing Protocols for Real-World Parsing -- An Object-Oriented Model and its Preliminary Evaluation
We argue for a performance-based design of natural language grammars and
their associated parsers in order to meet the constraints imposed by real-world
NLP. Our approach incorporates declarative and procedural knowledge about
language and language use within an object-oriented specification framework. We
discuss several message-passing protocols for parsing and provide reasons for
sacrificing completeness of the parse in favor of efficiency based on a
preliminary empirical evaluation.Comment: 12 pages, uses epsfig.st
Towards virtual communities on the Web: Actors and audience
We report about ongoing research in a virtual
reality environment where visitors can interact with
agents that help them to obtain information, to perform
certain transactions and to collaborate with them in order
to get some tasks done. Our environment models a
theatre in our hometown. We discuss attempts to let this
environment evolve into a theatre community where we
do not only have goal-directed visitors, but also visitors
that that are not sure whether they want to buy or just
want information or visitors who just want to look
around. It is shown that we need a multi-user and multiagent
environment to realize our goals. Since our environment
models a theatre it is also interesting to investigate
the roles of performers and audience in this environment.
For that reason we discuss capabilities and personalities of agents. Some notes on the historical development of networked communities are included
Agents for educational games and simulations
This book consists mainly of revised papers that were presented at the Agents for Educational Games and Simulation (AEGS) workshop held on May 2, 2011, as part of the Autonomous Agents and MultiAgent Systems (AAMAS) conference in Taipei, Taiwan. The 12 full papers presented were carefully reviewed and selected from various submissions. The papers are organized topical sections on middleware applications, dialogues and learning, adaption and convergence, and agent applications
Constructing Social Systems through Computer-Mediated Communication
The question whether computer-mediated communication can support the formation of
genuine social systems is addressed in this paper. Our hypothesis, that technology creates
new forms of social systems beyond real-life milieus, includes the idea that the
technology itself may influence how social binding emerges within on-line environments.
In real-life communities, a precondition for social coherence is the existence of social
conventions. By observing interaction in virtual environments, we found the use of a
range of social conventions. These results were analyzed to determine how the use and
emergence of conventions might be influenced by the technology. One factor contributing
to the coherence of on-line social systems, but not the only one, appears to be the degree
of social presence mediated by the technology. We suggest that social systems can
emerge by computer-mediated communication and are shaped by the media of the
specific environment
