Hierarquias de Conceitos para um Ambiente Virtual de Ensino Extraídas de um Corpus de Jornais Populares

In this paper we present conceptual hierarchies automatically obtained from the popular newspaper Diário Gaúcho. The hierarchies were generated by means of ExATOlp tool through the extraction of noun phrases considered concept candidates by applying linguistic and statistic approaches. When accessed in a virtual learning environment, the hierarchies became a differentiated resource for vocabula...

Operadores de Seleção por Similaridade para Sistemas de Gerenciamento de Bases de Dados Relacionais

Searching operations in complex datasets are performed using comparison criteria based on similarity because equality comparison are barely useful and those based on the ordering relationships cannot be applied due to the nature of these datasets. There are two basic operators for similarity queries: Range Query and k-Nearest Neighbor Query. A great amount of research was done to achieve effect...

Protocolo de Leilões Simultâneos com Escalonamento: Aplicação ao Problema de Planejamento de Movimentações de Derivados de Petróleo

In supply chains of the petroleum industry, fulfill demand and maintain an adequate inventory level for multiple classes of petroleum products is a crucial issue. Basically, this kind of chain consists of several elements like producer bases, consumer bases and terminals that are linked by 1 Programa de Pós-Graduação em Engenharia Elétrica e Informática Industrial (CPGEI) Universidade Tecnológi...

Seleção de Valores para Preenchimento Automático de Formulários Web

In this paper we present a proposal for the implementation and evaluation of some strategies for automatically filling Web forms. The goal is to minimize the number of queries that must be generated for automatic filling of Web forms. Our solution takes a form as input, extracts fields from it and fills appropriate fields. Experiments are presented to evaluate the proposed strategies.
