This thesis investigates what knowledge is necessary to solve mechanics problems. A program NEWTON is described which understands and solves problems in mechanics mini-world of objects moving on surfaces. Facts and equations such as those given in mechanics text need…

This project investigates how doctoral students make
‘learning leaps’ to recognise and cross conceptual
and skills thresholds in their research and ways in
which they can be best supported to do so. It
responds to current national and international
concerns…

This paper presents an overview of a theory of discourse structure, and discusses a model for assimilating text into a frame-based data structure. The model has been applied to the analysis of news articles. The theory assumes sentences contain links…

How can we insure that knowledge embedded in a program is applied effectively? Traditionally the answer to this question has been sought in different problem solving paradigms and in different approaches to encoding and indexing knowledge. Each of these is…

El pensamiento filosófico, introducido a partir de la obra de los presocráticos, particularmente de Heráclito y Jenófanes, formula unas consideraciones sobre la creación poética, las cuales discrepan de la concepción de ella como fruto de la actividad inspiradora de la…

Se propone una metodología para la construcción automatizada de KOS adaptable a
diferentes entornos a partir de un corpus documental y unas aplicaciones de tratamiento textual
que soporten todo el proceso de construcción y mantenimiento automatizado del KOS. Esta
metodología…

El subcomplejo sarcoglicano-sarcospan (SG-SSPN), el cual forma parte del
complejo de proteínas asociadas a la distrofina (DGC), se encuentra
compuesto por un grupo de glicoproteínas transmembranales denominadas
sarcoglicanos (SGs; subunidades y ) y por la tetraspanina asociada de nombre

In a Communication Bootstrapping system, peer components with different perceptual worlds invent symbols and syntax based on correlations between their percepts. I propose that Communication Bootstrapping can also be used to acquire functional definitions of words and causal reasoning knowledge.…

This paper describes a natural language system START. The system analyzes English text and automatically transforms it into an appropriate representation, the knowledge base, which incorporates the information found in the text. The user gains access to information stored in…

The report describes a recognition system called GROPER, which performs grouping by using distance and relative orientation constraints that estimate the likelihood of different edges in an image coming from the same object. The thesis presents both a theoretical analysis…
