PAGOdA : pay-as-you-go ontology query answering using a datalog reasonerZhou, Yujiao January 2015 (has links)
Answering conjunctive queries over ontology-enriched datasets is a core reasoning task for many applications of semantic technologies. Conjunctive query answering is, however, computationally very expensive, which has led to the development of query answering procedures that sacrifice either the expressive power of ontology languages, or the completeness of query answers in order to improve scalability. This thesis describes a hybrid approach to query answering over OWL 2 ontologies that combines a datalog reasoner with a fully-fledged OWL 2 reasoner in order to provide scalable "pay-as-you-go" performance. The key feature of this hybrid approach is that it delegates the bulk of the computation to the datalog reasoner and resorts to expensive OWL 2 reasoning only as necessary to fully answer the query. Although the main goal of this thesis is to efficiently answer queries over OWL 2 ontologies, the technical results are more general and the approach is applicable to first-order knowledge representation languages that can be captured by rules allowing for existential quantification and disjunction in the head; the only assumption is the availability of a datalog reasoner and a fully-fledged reasoner for the language of interest, both of which are used as "black boxes". All techniques proposed in this thesis are implemented in the PAGOdA system, which combines the datalog reasoner RDFox and the OWL 2 reasoner HermiT. An extensive evaluation shows that PAGOdA succeeds in providing scalable pay-as-you-go query answering for a wide range of OWL 2 ontologies, datasets and queries.

Emprego de um software baseado em mineração de texto e apresentação gráfica multirrepresentacional como apoio à aprendizagem de conceitos científicosCosta, Ana Paula Metz January 2014 (has links)
Esta dissertação apresenta quatro estudos independentes, do tipo quasi-experimental com aplicação de pré-teste e pós-testes e grupo de controle não equivalente. O objetivo dos quatro estudos é investigar como uma ferramenta baseada em mineração de texto e apresentação gráfica multirrepresentacional (SOBEK) pode contribuir com o processo de construção de conceitos científicos. Textos do tipo refutacional oriundos de pesquisas internacionais já publicadas foram utilizados nos estudos, assim como os testes de desempenho correspondentes a cada texto. Os conceitos abordados são energia, evolução Darwiniana e a natureza particulada da matéria. Realizados em uma escola municipal da região metropolitana de Porto Alegre, os estudos contaram com a participação de 73 alunos distribuídos em duas turmas de 8º ano e duas turmas de 9º ano. As análises estatísticas dos escores registrados pelos alunos nos testes identificaram uma melhora significativa no desempenho dos alunos de 9º ano que utilizaram a ferramenta SOBEK como apoio para o estudo do texto. Para os alunos de 8º ano, não houve diferenças estatisticamente significativas entre os alunos que usaram a ferramenta e os que responderam questionários sobre o texto. Estudos de maior profundidade são necessários para identificar a ocorrência e extensão de possíveis mudanças conceituais promovidas pela abordagem proposta. / This work presents four independent studies, in a quasi-experimental design with application of pre-test and post-tests with non-equivalent control groups. The set of four studies aim to investigate how a tool based on text mining and multirrepresentacional graphical presentation (SOBEK) can contribute to the process of constructing scientific concepts. Refutational texts from international published researches were used in the studies, as well as the corresponding performance´s tests about each text. The concepts covered are energy, Darwinian evolution and the particulate nature of matter. Performed in a municipal school in the Porto Alegre´s metropolitan region, in Southern Brazil, the studies included 73 students divided into two classes of 7th grade and two classes of 8th grade. Statistical analysis of the scores performed by students in the tests show a significant improvement in student´s performance in 8th grade that used the SOBEK tool as support for the study of the text. For students in grade 7th, there were no statistically significant differences in the performances of students who used the SOBEK tool and those who answered questionnaires about the text. More detailed studies are needed to identify the occurrence and the extent of possible conceptual changes supported by the proposed approach.
