Ontology based Clinical Practice Justification in Natural Language
Mendes, David; Rodrigues, Irene Pimenta; Baeta, CarlosOne of the most important contributions that any decision support system can make to achieve wide acceptance among any community is to be able to justify its own suggestions. When dealing with highly technical and scientifically advanced practitioners like medical doctors or any other related clinical workers, the ability to justify itself using the domain specialist usual terminology and technicalities i...
Advances to Semantic Interoperability through CPR Ontology extracting from SOAP...
Mendes, David; Rodrigues, Irene PimentaWe present the work done as a contribution to use an enriched ontology as the support for Semantic Interoperability among technicians and systems in healthcare providing environments. Clinical practice ontologies are the next generation workhorse for automatic reasoning using Semantic Web techniques and tools in the healthcare sub-domain. Acquisition from semi-structured data that renders a full picture of the ...
Cooperative Question Answering Semantic Web
Melo, Dora; Rodrigues, Irene Pimenta; Nogueira, VitorIn this paper we propose a Cooperative Question Answering System that takes as input queries expressed in natural language and is able to return a cooperative answer obtained from resources in the Semantic Web, more specifically DBpedia represented in OWL/RDF as knowledge base and WordNet to build similar questions. Our system resorts to ontologies not only for reasoning but also to find answers and is independ...
INESC, Porto at TRECVID 2007: Automatic and Interactive Video Search
Calistru, Catalin; Ribeiro, Cristina; David, Gabriel; Rodrigues, Irene Pimenta; Laboreiro, GustavoThe INESC Porto group has participated in the search task (automatic and interactive). Our approach combines high-level features (the 39 con- cepts of the LSCOM-Lite set) with low-level features. We use a large set of low-level features with the intention of analysing as many facets as possible of each shot. The aggregation of large feature sets can be time consuming as it needs to be done at query time. We hav...
Using a Logic Programming Framework to Control Database Query Dialogues in Natu...
Quintano, Luis; Rodrigues, Irene PimentaWe present a natural language question/answering system to interface the University of Évora databases that uses clarification dialogs in order to clarify user questions. It was developed in an integrated logic programming framework, based on constraint logic programming using the GnuProlog(-cx) language [2,11] and the ISCO framework [1]. The use of this LP framework allows the integration of Prolog-like infere...
Um sistema de pergunta-resposta para uma base de conhecimentos
Quaresma, Paulo; Rodrigues, Irene Pimenta; Prolo, Carlos; Vieira, RenataNeste artigo apresentamos a metodologia seguida para a construc ̧a ̃o de um sistema de pergunta- resposta sobre uma base de documentos em Portuguˆes. Descrevemos o sistema que tem dois mo ́dulos distintos: ana ́lise pr ́evia dos documentos (extracc ̧a ̃o de informac ̧a ̃o) e processamento das perguntas (recuperac ̧a ̃o de informac ̧a ̃o). O nosso sistema procura fazer um processamento, do corpus e da perguntas,...
KNOWLEDGE REPRESENTATION APPROACH TO CLOSED LOOP CONTROL SYSTEM - A TANK SY...
Rato, Luís; Rodrigues, Irene Pimenta; Gomes, RuiControl engineering problems are dealt within a plethora of methods and approaches depending on the a priori knowledge, the description of the process to control, and the main control goal. Classical control theory is mainly based on properties of numerical models. This paper presents an approach that applies to a class of processes described by numerical and logical relations using inference and a knowledge ba...
