CÁLCULO DE UN ÍNDICE DE HUMEDAD RELATIVA DEL AIRE, CONSIDERANDO LA RESILIENCIA ...
Marques da Silva, José; Bugalho, Lourdes; Sousa, Adélia; Pessanha, Luis; Quaresma, PauloUn índice de humedad relativa (IHR-LST), que se calcula utilizando la diferencia entre la LST (temperatura de la superficie del terreno), una hora después del amanecer y una hora después del medio día solar, dividida por el número de horas entre estos dos periodos, se compara con la humedad relativa del aire de un conjunto seleccionado de estaciones meteorológicas Los resultados muestran una clara asociación en...
Cálculo de um índice de humidade relativa do ar, considerando a resiliência tér...
Marques da Silva, José; Bugalho, Lourdes; Sousa, Adélia; Pessanha, Luis; Quaresma, PauloA relative humidity index (IHR-LST), estimated using the difference between the temperature LST (Land Surface Temperature), one hour after sunrise and one hour after solar noon, divided by the number of hours mediate these two periods, is compared with the air relative humidity of a selected set of meteorological stations.The results show a clear association between both values, relative humidity index and air ...
An Approach to the Main Task of QA4MRE-2013
Santos, Marília; Saias, José; Quaresma, PauloThis article describes the participation of a group from the University of Évora in the CLEF2013 QA4MRE main task. Our system has a superficial text analysis based approach. The methodology starts with the preprocessing of background collection documents, whose texts are lemmatized and then indexed. Named entities and numerical expressions are sought in questions and their candidate answers. Then the lemmatize...
BINLI: An Ontology-Based Natural Language Interface for Multidimensional Data A...
Saias, José; Quaresma, Paulo; Salgueiro, Pedro; Santos, TiagoCurrent technology facilitates access to the vast amount of information that is produced every day. Both individuals and companies are active consumers of data from the Web and other sources, and these data guide decision making. Due to the huge volume of data to be processed in a business context, managers rely on decision support systems to facilitate data analysis. OLAP tools are Business Intelligence soluti...
DI@UE in CLEF2012: question answering approach to the multiple choice QA4MRE ch...
Saias, José; Quaresma, PauloIn the 2012 edition of CLEF, the DI@UE team has signed up for Question Answering for Machine Reading Evaluation (QA4MRE) main task. For each question, our system tries to guess which of the five hypotheses is the more plausible response, taking into account the reading test content and the documents from the background collection on the question topic. For each question, the system applies Named Entity Recogni...
Analyzing the strength of ties of Retweet in health domain
Weitzel, Leila; Quaresma, Paulo; Palazzo, JoséSocial Network (SN) is created whenever people interact with other people.

Users follow someone mostly because they share common interests and they may exchange messages called tweets. If a user post...
Using machine learning algorithms to identify named entities in legal documents...
Poudyal, Prakash; Borrego, Luís; Quaresma, PauloThis paper deals with accuracy and performance of var- ious machine learning algorithms in the recognition and extraction of different types of named entities such as date, organization, reg- ulation laws and person. The experiment is based on 20 judicial decision documents from European Lex site. The obtained results were proposed for the selection of the best algorithm that selects appropriate maximum entitie...
Classificação de Argumentos Sintácticos: Aproximação preliminar
Sequeira, João; Gonçalves, Teresa; Quaresma, PauloEste artigo apresenta uma aproximação preliminar de uma vertente pouco explorada do processamento de linguagem natural para a líıngua Portuguesa, a classificação de argumentos sintácticos. Primeiro é dada uma introdução à classificação de argumentos sintácticos, posteriormente são explicados os passos necessários à criação de um classificador utilizando a ferramenta MinorThird. O desempenho foi verificado nos a...
Using Linguistic Information and Machine Learning Techniques to Identify Entiti...
Gonçalves, Teresa; Quaresma, PauloInformation extraction from legal documents is an important and open problem. A mixed approach, using linguistic information and machine learning techniques, is described in this paper. In this approach, top-level legal concepts are identified and used for document classifica- tion using Support Vector Machines. Named entities, such as, locations, organizations, dates, and document references, are identified us...
Tomo-GPU: um ambiente de resolução de problemas destinado à análise de dados to...
Quaresma, Paulo Jorge; Medeiros, Pedro Duarte; Lopes, Adriano; Preto, Bruno; Velhinho, AlexandreA caracterização micro-estrutural de materiais compósitos utiliza a tomografia de raios X para capturar informação sobre as características internas das amostras, de forma a elucidar o investigador sobre as suas propriedades intrínsecas. Os dados tomográficos em bruto carecem de processamento mediante diversas operações computacionais, que começam pela eliminação de ruído e outros artefactos. A experiência adqu...
