This paper describes the development of an image retrieval
system that combines probabilistic and ontological information1. The
process is divided in two different stages: indexing and retrieval. Three
information flows have been created with different kind of information
each one:…

Within the context of globalisation, the diversification of learning contexts and the implementation of national and transnational policy measures concerning teacher education, teaching competences and lifelong learning, teacher identity has emerged as being problematic and paradoxical. Drawing on recent research…

We present a new algorithm to process captured images of reflected Placido rings. Up to our knowledge, conventional topographers transform from Cartesian to polar coordinates and vice-versa, thus extrapolating corneal data and introducing noise and image artefacts. Moreover, captured data…

Algunas aplicaciones del procesamiento del lenguaje natural, p.ej. la traducción
automática, requieren una base de conocimiento provista de representaciones conceptuales que
puedan reflejar la estructura del sistema cognitivo del ser humano. En cambio, tareas como la
indización automática o la…

Data mining is at the core of the knowledge discovery process. However, an initial preprocessing step is crucial for assuring reliable results within this process. Preprocessing of data is a time-consuming and non-trivial task since data quality issues should be…

A concept of pedagogical process knowledge (PPK) is introduced to partner pedagogical content knowledge (PCK). This concept arises from observing the learning of teachers engaged in a course supporting them in introducing more inquiry-based methods into their practice. This course…

The purpose of the study was to investigate whether teachers’ knowledge of student assessment was influenced by their gender and if it was related to their teaching experience (years in education). One hundred and twenty six physical education teachers (n=126)…

The methodology “b-learning” is a new teaching scenario and it requires the creation, adaptation and application of new learning tools searching the assimilation of new collaborative competences. In this context, it is well known the knowledge spirals, the situational leadership…

The underlying assumption of this study is the understanding of a specialized term as a summary of disciplinary knowledge, formalized at a textual level in the contextual relations which structure disciplinary lexical knowledge and are therefore essential for the successful…

Obtaining an implementation of a data warehouse is a complex task that forces designers to acquire wide knowledge of the domain, thus requiring a high level of expertise and becoming it a prone-to-fail task. Based on our experience, we have…
