MIRACLE at GeoCLEF Query Parsing 2007: Extraction and Classification of Geographical Information

This paper describes the participation of MIRACLE research consortium at the Query Parsing task of GeoCLEF 2007. Our system is composed of three main modules. First, the Named Geo-entity Identifier, whose objective is to perform the geo-entity identification and tagging, i.e., to extract the “where” component of the geographical query, should there be any. This module is based on a gazetteer built up from the Geonames geographical database and carries out a sequential process in three steps that consist on geo-entity recognition, geo-entity selection and query tagging. Then, the Query Analyzer parses this tagged query to identify the “what” and “geo-relation” components by means of a rule-based grammar. Finally, a two-level multiclassifier first decides whether the query is indeed a geographical query and, should it be positive, then determines the query type according to the type of information that the user is supposed to be looking for: map, yellow page or information. According to a strict evaluation criterion where a match should have all fields correct, our system reaches a precision value of 42.8% and a recall of 56.6% and our submission is ranked 1st out of 6 participants in the task. A detailed evaluation of the confusion matrixes reveal that some extra effort must be invested in “user-oriented” disambiguation techniques to improve the first level binary classifier for detecting geographical queries, as it is a key component to eliminate many false-positives

Narración futbolística: conducir; pasear y surfear

Los narradores somos lo que quieran los partidos. Sólo hay que intentar latir a su compás y no molestarles demasiado. En el periodismo deportivo, la clásica crónica ha dado paso a un nuevo formato más centrado en la narración. Retransmitir un acontecimiento deportivo es armar un relato capaz de desbordar los hechos sin más y cautivar a la audiencia de una manera más profunda e intensa.Universidad de Málaga.

Redes sociales y docencia en Tercer Ciclo

El uso de las redes sociales en el ámbito universitario de tercer ciclo puede ser un gran aliado en la docencia y aprendizaje. Y esto en dos sentidos, en el ámbito laboral para el desempeño de la profesión y en el investigador para conocer qué pasa en la sociedad en la que se desenvuelve el investigador, sobre todo cuando hablamos del ámbito de las ciencias sociales. En este artículo analizamos la importancia del uso de las redes sociales en el ámbito universitario, centrándonos en el Máster Universitario en Comunicación Institucional y Política de la Universidad de Sevilla

Remarks on multisymplectic reduction

The problem of reduction of multisymplectic manifolds by the action of Lie groups is stated and discussed, as a previous step to give a fully covariant scheme of reduction for classical field theories with symmetries.Comment: 9 pages. Some comments added in the section "Discussion and outlook" and in the Acknowledgments. New references are added. Minor mistakes are correcte

The Hamiltonian tube of a cotangent-lifted action

The Marle-Guillemin-Sternberg (MGS) form is local model for a neighborhood of an orbit of a Hamiltonian Lie group action on a symplectic manifold. One of the main features of the MGS form is that it puts simultaneously in normal form the existing symplectic structure and momentum map. The main drawback of the MGS form is that it does not have an explicit expression. We will obtain a MGS form for cotangent-lifted actions on cotangent bundles that, in addition to its defining features, respects the additional fibered structure present. This model generalizes previous results obtained by T. Schmah for orbits with fully-isotropic momentum. In addition, our construction is explicit up to the integration of a differential equation on G. This equation can be easily solved for the groups SO(3) or SL(2), thus giving explicit symplectic coordinates for arbitrary canonical actions of these groups on any cotangent bundle.Peer ReviewedPostprint (author's final draft
