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...

Definição e Avaliação de uma Abordagem para Extração e Catalogação de Conteúdo Obtido da Deep Web

This paper presents an approach for the extraction and labeling of data presented in Deep Web databases. Such a data are extracted from a set of HTML pages generated as the result of a query posed on the hidden database through a Web form. Data labeling (and persistence) aims at providing further structured queries over this hidden content. Preliminary experiments had demonstrated that the prop...

Uma Proposta de Ontologia de Referência para Autorização Orçamentária e Execução da Despesa Pública

There are a number of barriers for the consumption of government expenditure data by citizens and computational systems. These include the lack of standardization in the structure of data in portals, as well as the significant complexity of the (highly technical and specialized) subject domain. In this paper we address these problems proposing a reference ontology for the Brazilian government b...

Geração Automática de Visões de Objeto de Dados Relacionais

Views are used to publish data from a database into a new structure or schema. The definition of object views over relational data allows this data to be published into an object oriented structure, without the need for changing the database schema. This paper proposes a three-step approach to generate object views of relational data. First, the user defines the view schema. Second, the user id...
