Object-oriented database management systems (OODBMS) are especially suited to model complex and highly dynamic application domains. In this paper, we propose a schema uersioning approach which supports the dynamic change of an objectoriented database schema while it is used by running applications. OUT mechanism allows to have applications working with diflerent schema weTsions on top of the sa...

The use of multi-agent systems to model and control complex domains is increasing. The application of multi-agent systems to distributed real-world domains motivates the development of domain independent agent architectures to foster the re-use of existing research. A domain independent agent architecture is defined as a set of representations, reasoning mechanisms and algorithms that can be us...

schema matching is a critical step in many applications, such as data warehouse loading, online analytical process (olap), data mining, semantic web [2] and schema integration. this task is defined for finding the semantic correspondences between elements of two schemas. recently, schema matching has found considerable interest in both research and practice. in this paper, we present a new impr...

The aim of this study is to examine the effects of personality (temperament and character) on specific depression and specific anxiety. A total of 541 Japanese undergraduates were investigated by using the Temperament and Character Inventory (TCI) and the Hospital Anxiety and Depression (HAD) scale. Hierarchical multiple regression analyses demonstrated that specific depression was predicted by...

The combined effects of counseling and the Transcendental Meditation program were compared with the effect of the Transcendental Meditation program alone and counseling alone on three groups of young adults over an eight-week period. Changes in locus of control, present-orientation, and self-support were measured using the Adult NowickiStrickland Internal/External Locus of Control Scale and the...

Advanced object-oriented applications require the management of schema versions, in order to cope with changes in the structure of the stored data. Two types of versioning have been separately considered so far: branching and temporal. The former arose in application domains like CAD/CAM and software engineering, where different solutions have been proposed to support design schema versions (co...

overlapping/related ontologies or schemas. • support for Semantic match approach STROMA Evaluation STROMA follows a 2-step approach to semantic matching Rahm, E.: Towards largescale schema and ontology matching. Recently large amounts of schema data, which describe data structure of various domains such as purchase order, health, publication, geography, agriculture. Increase in web and informat...

The identification of semantic relationships between schema elements, or schema matching, is the initial step in the integration of data sources. Existing approaches in automatic schema matching have mainly been concerned with discovering equivalence relationships between elements. In this paper, we present an approach to automatically discover richer and more expressive semantic relationships ...

Data integration is one of the main problems in distributed data sources. An approach is to provide an integrated mediated schema for various data sources. This research work aims at developing a framework for defining an integrated schema and querying on it. The basic idea is to employ recent standard languages and tools to provide a unified data integration framework. RDF is used for integrat...

Schema/ontology matching is a critical problem in many application domains, such as, semantic web, schema/ontology integration, data warehouses, e-commerce, catalog matching, etc. Many diverse solutions to the matching problem have been proposed so far. In this paper we present a taxonomy of schema-based matching techniques that builds on the previous work on classifying schema matching approac...
