The thesis explores architectural form generation through two behavior based artificial intelligence approaches: the communication of agents in an unpredictable simulation system, and the codification of information within an evolutionary process. Both concepts stem from the evaluation of potentially definable…

I have invented "Internet Fish," a novel class of resource-discovery tools designed to help users extract useful information from the Internet. Internet Fish (IFish) are semi-autonomous, persistent information brokers; users deploy individual IFish to gather and refine information related to…

Information Retrieval Systems normally deal with keywordbased technologies. Although those systems reach satisfactory results, they aren’t able to answer more complex queries done by users, especially those directly in natural language. To do that, there are the KnowledgeBased Systems, which…

This paper presents a proposal for an architecture that integrates knowledge discovery systems (automatic acquisition) and knowledge based systems (experts systems). This work formulates considerations over the viability of the implementation of this architecture according to the advance of the…

We describe an adaptation of the knowledge gradient, originally developed for discrete ranking and selection problems, to the problem of calibrating continuous parameters for the purpose of tuning a simulator. The knowledge gradient for continuous parameters uses a continuous approximation…

The supervision of postgraduate Master's Degree dissertations has attracted little attention in the
academic literature and is an under researched area of supervisory activity. This research was a
response to generate new knowledge concerning the praxis of supervisors who supervise…

Content vocabulary may have different connotative values and different denotational meanings in different languages according to cultural idiosyncracy, manifested in culture-specific "key" meanings and culture-related scripts. Our claim here is that, even in all these cases involving the use of…

In recent research, it is claimed that deviant features of interlanguage grammars arise only
from the users' knowledge of the rule system of the target language. This paper examines
the relative contribution of the rule system of each of the…

The chemical effects of acoustic cavitation are obtained in sono-reactors built-up from a vessel and an ultrasonic
source. In this paper, simulations of an existing sono-reactor are carried out, using a linear acoustics model, accounting
for the vibrations of the…

This paper presents the main
characteristics of an Agent-based Architecture
for the design and implementation
of a Spoken Dialogue System. From
a theoretical point of view, the system is
based on the Information State Update
approach, in particular, the system…
