The Use of Latent Semantic Indexing to Mitigate OCR Effects of Related Document Images

Due to both the widespread and multipurpose use of document images and the current availability of a high number of document images repositories, robust information retrieval mechanisms and systems have been increasingly demanded. This paper presents an approach to support the automatic generation of relationships among document images by exploiting Latent Semantic Indexing (LSI) and Optical Character Recognition (OCR). We developed the LinkDI (Linking of Document Images) service, which extracts and indexes document images content, computes its latent semantics, and defines relationships among images as hyperlinks. LinkDI was experimented with document images repositories, and its performance was evaluated by comparing the quality of the relationships created among textual documents as well as among their respective document images. Considering those same document images, we ran further experiments in order to compare the performance of LinkDI when it exploits or not the LSI technique. Experimental results showed that LSI can mitigate the effects of usual OCR misrecognition, which reinforces the feasibility of LinkDI relating OCR output with high degradation.

GIS/GPS to document increased access to community-based treatment for tuberculosis in Africa

Application of geographic information system (GIS) and global positioning system (GPS) technology in the Hlabisa community-based tuberculosis treatment programme documents the increase in accessibility to treatment after the expansion of the service from health facilities to include community workers and volunteers.

Document retrieval for e-mail search and discovery using Formal Concept Analysis

This paper discusses a document discovery tool based on Conceptual Clustering by Formal Concept Analysis. The program allows users to navigate e-mail using a visual lattice metaphor rather than a tree. It implements a virtual. le structure over e-mail where files and entire directories can appear in multiple positions. The content and shape of the lattice formed by the conceptual ontology can assist in e-mail discovery. The system described provides more flexibility in retrieving stored e-mails than what is normally available in e-mail clients. The paper discusses how conceptual ontologies can leverage traditional document retrieval systems and aid knowledge discovery in document collections.

Agroecologia periurbana a Sant Cugat: document base per a la redacció del Pla de Gestió i Desenvolupament del parc rural de la Torre Negra

El parc rural de la Torre Negra ha estat protegit recentment després de 15 anys de lluita ciutadana, gràcies a l’aprovació del Pla Especial de Protecció i Millora el 29 de juny del present any. A partir d’ara, s’obre un ampli ventall de possibilitats per a la seva gestió i desenvolupament. En aquest context és on es situa el present estudi, amb la finalitat de presentar unes línies estratègiques bàsiques per a iniciar l’activitat al parc. Una activitat que té en el punt de mira el desenvolupament rural de l’espai i la transformació social de la ciutadania.

DETERMINE Working document #4 'Economic arguments for addressing social determinants of health inequalities'

The Institute of Public Health in Ireland (IPH) is a partner in the European project DETERMINE, building on its previous involvement in the Closing the Gap project in 2004-2006. In Year 2 the DETERMINE project  focused on identifying and exploring economic arguments to support action on social determinants of health inequalities.  Working document #4 'Economic arguments for addressing social determinants of health inequalities' presents the findings.

DETERMINE Working Document #1 'Policies and actions addressing the social determinants of health inequalities: examples of activity at EU member state level in Europe'

The Institute of Public Health in Ireland (IPH) is a partner in the European project DETERMINE, building on its previous involvement in the Closing the Gap project in 2004-2006. In the first year of the project (2007-2008) 15 DETERMINE partners identified policies and actions that have taken place within countries, and at the EU level, to address Social Determinants of Health Inequalities. These policies and actions were identified via a questionnaire, which also identified structures and tools/mechanisms being used in the country to support a 'health in all policy' approach.

A Fitter Future for All: Consultation Document

The prevalence of people who are overweight and obese has been steadily rising in Northern Ireland, and in the western world, over the last few decades. It has been described as an “obesity time-bomb”, given the impact that obesity can have on physical and mental health and wellbeing.Evidence has shown that, while weight gain is the result of a relatively simple energy imbalance, the causes that underpin changes to energy intake and expenditure are very complex and cover issues such as social and individual psychology, physiology, food production and consumption, individual activity, and the built environment.This Framework aims to “empower the population of Northern Ireland to make healthy choices, and reduce the level of harm related to overweight and obesity, by creating an environment that supports and promotes a physically active lifestyle and a healthy diet”.In addition, the following overarching target has been set: to reduce the level of obesity in Northern Ireland to the 2005-06 level by 2021.
