The ODMG standard is a proposal to solve one of the main drawbacks of object-oriented databases (OODBs): the lack of a standard for object definition and management. Nevertheless, this standard does not offer a solution for another lack of OODBs, related to the definition of external schemas. In this work, a methodology to define external schemas in ODMG databases is put forward. This methodolo...

In cognitive science, image schemas are identified as fundamental patterns of cognition. They are schematic prelinguistic conceptualisations of events and serve as conceptual building blocks for concepts. This paper proposes that image schemas can play an important role in computational concept invention, namely within the computational realisation of conceptual blending. We propose to build a ...

Sharing schemas is a shortcut to data interoperability, while in grid environments there are many difficulties such as schema disagreements and schema evolutions. We propose a new ”mappings first, schemas later” schema model, named Grid Schema. The Grid Schema uses the idea of context-free mapping to modularize schemas and its translation rules. This is incorporated into its schema validation m...

Merging schemas to create a mediated view is a recurring problem in applications related to data interoperability. The task becomes particularly challenging when the schemas are highly heterogeneous and autonomous. Classical data integration systems rely on a mediated schema created by human experts through an intensive design process. Automatic generation of mediated schemas is still a goal to...

bounded scope dialogue with the user in order to collect his suggestions about the structure and content of the texts to be su~mmrized, and his requirements on the summary to be generated. This information is embedded in two different frameworks called working_ text schema and working summmar~, schema which contain the user's suggestions and requirements, respectively. The schemas will constitu...

There is a need to integrate XML schemas, i.e., schemas written in XML Schema, into UML-based software development processes. Not only the production of XML schemas out of UML models is required, but even more the integration of given XML schemas as input into the development process. In the model driven architecture, a two step integration is assumed, comprising a platform specific model and a...

OBJECTIVE The first aim of this study was to examine the relationships between perceived parenting styles and interpersonal schemas. The second purpose was to investigate the mediator role of interpersonal schemas between perceived parenting styles and psychological symptoms. METHOD University students (N=94), ages ranging between 17-26, attending to different faculty and classes, have comple...

<span>On the internet where number of database developers is increasing with availability huge data to be stored and queried. Establishing relations between various schemas helping by filtering, prioritizing, suggesting relevant schema a requirement. Recommendation system plays an important role in searching through large volume dynamically generated provide personalized services. Althoug...

The aim of this study was to assess the reliability and validity of the Questionnaire of Cognitive Schema Activation in Sexual Context (QCSASC; Nobre & Pinto-Gouveia, 2000b). A total of 319 individuals (96 with sexual dysfunctions and 223 without sexual dysfunctions) participated in the study. The QCSASC assesses 28 self-schemas proposed by J. S. Beck (1995), usually associated with psychologic...
