Automatic translation of formal data specifications to voice data-input applications.
This thesis introduces a complete solution for automatic translation of formal data specifications to voice data-input applications. The objective of the research is to automatically generate applications for inputting data through speech from specifications of the structure of the data. The formal data specifications are XML DTDs. A new formalization called Grammar-DTD (G-DTD) is introduced as an extended DTD that contains grammars to describe valid values of the DTD elements and attributes. G-DTDs facilitate the automatic generation of Voice XML applications that correspond to the original DTD structure. The development of the automatic application-generator included identifying constraints on the G-DTD to ensure a feasible translation, using predicate calculus to build a knowledge base of inference rules that describes the mapping procedure, and writing an algorithm for the automatic translation based on the inference rules.Dept. of Computer Science.

Language acquisition and machine learning
In this paper, we review recent progress in the field of machine learning and examine its implications for computational models of language acquisition. As a framework for understanding this research, we propose four component tasks involved in learning from experience - aggregation, clustering, characterization, and storage. We then consider four common problems studied by machine learning researchers - learning from examples, heuristics learning, conceptual clustering, and learning macro-operators - describing each in terms of our framework. After this, we turn to the problem of grammar acquisition, relating this problem to other learning tasks and reviewing four AI systems that have addressed the problem. Finally, we note some limitations of the earlier work and propose an alternative approach to modeling the mechanisms underlying language acquisition
Interactive Technologies for the Public Sphere Toward a Theory of Critical Creative Technology
Digital media cultural practices continue to address the social, cultural and aesthetic
contexts of the global information economy, perhaps better called ecology, by inventing
new methods and genres that encourage interactive engagement, collaboration, exploration
and learning. The theoretical framework for creative critical technology evolved from the
confluence of the arts, human computer interaction, and critical theories of technology.
Molding this nascent theoretical framework from these seemingly disparate disciplines was
a reflexive process where the influence of each component on each other spiraled into the
theory and practice as illustrated through the Constructed Narratives project. Research
that evolves from an arts perspective encourages experimental processes of making as a
method for defining research principles. The traditional reductionist approach to research
requires that all confounding variables are eliminated or silenced using methods of
statistics. However, that noise in the data, those confounding variables provide the rich
context, media, and processes by which creative practices thrive. As research in the arts
gains recognition for its contributions of new knowledge, the traditional reductive practice
in search of general principles will be respectfully joined by methodologies for defining
living principles that celebrate and build from the confounding variables, the data noise.
The movement to develop research methodologies from the noisy edges of human
interaction have been explored in the research and practices of ludic design and ambiguity
(Gaver, 2003); affective gap (Sengers et al., 2005b; 2006); embodied interaction (Dourish,
2001); the felt life (McCarthy & Wright, 2004); and reflective HCI (Dourish, et al., 2004).
The theory of critical creative technology examines the relationships between critical
theories of technology, society and aesthetics, information technologies and contemporary
practices in interaction design and creative digital media. The theory of critical creative
technology is aligned with theories and practices in social navigation (Dourish, 1999) and
community-based interactive systems (Stathis, 1999) in the development of smart
appliances and network systems that support people in engaging in social activities,
promoting communication and enhancing the potential for learning in a community-based
environment. The theory of critical creative technology amends these community-based
and collaborative design theories by emphasizing methods to facilitate face-to-face
dialogical interaction when the exchange of ideas, observations, dreams, concerns, and
celebrations may be silenced by societal norms about how to engage others in public
spaces.
The Constructed Narratives project is an experiment in the design of a critical creative
technology that emphasizes the collaborative construction of new knowledge about one's
lived world through computer-supported collaborative play (CSCP). To construct is to
creatively invent one's world by engaging in creative decision-making, problem solving
and acts of negotiation. The metaphor of construction is used to demonstrate how a simple
artefact - a building block - can provide an interactive platform to support discourse
between collaborating participants. The technical goal for this project was the development
of a software and hardware platform for the design of critical creative technology
applications that can process a dynamic flow of logistical and profile data from multiple
users to be used in applications that facilitate dialogue between people in a real-time
playful interactive experience
