Processamento de consultas na Web de Dados: uma abordagem para busca de fontes de dados relevantes

The adoption of Linked Data principles has contributed towards the creation of a Web of Data, allowing the development of applications and tools which run queries over available information. One of the main challenges for the query processing over the Web is the selection of relevant sources, i.e., sources which could contribute significantly to the result of a query. In this paper, we discuss ...

Construção de Mapa de Tópicos Semânticos Baseado na Integração de Fontes Heterogêneas

Nowadays one of the main challenges in the area of Information Retrieval (IR) is the development of systems that process correctly the idea or concept behind the queries issued by users. Conventional IR systems usually limit their indexing and retrieval capabilities to keywords, which creates poor results when indexing terms that are not listed in the query. Queries such as: “The king of Brazil...

Estimação de Probabilidade de Perda de Dados em Redes Através de Modelagem Multifractal de Tráfego e Teoria de Muitas Fontes

In this paper, we propose an approach to estimate the byte loss probability in computer network links considering multifractal properties of traffic flows. More specifically, we obtain a mathematical expression for the loss probability for finite buffer servers fed by multifractal traffic flows. The proposed approach is based on the Many Sources theory and on the multiplicative cascade based mu...

Uma Avaliação de Eficiência e Eficácia da Combinação de Técnicas para Deduplicação de Dados

Data Deduplication is the task of identifying and eliminating duplicate records in a single database. It is a complex process that involves several steps, including: defining blocking key, similarity function and indexing method. There are several approaches for each of these steps. In this context, the objective of this work is to find the best combination for such algorithms aiming to improve...
