As the amount of data grows very fast inside and outside of an enterprise, it is getting important to analyze both of them for getting total business intelligence. While online analytical processing (OLAP) techniques have been proven very useful for analyzing structured data, they face challenges in handling unstructured data. To this end, new multidimensional models have been proposed for OLAP purposes...
Resource Space Model (RSM) is a semantic data model for specifying, storing, managing, and locating versatile resources based on multi-dimensional categorization. However, the structure of the model needs to be extended for managing and searching contents. This paper proposes an extensive model of RSM to solve the problem by building a new layer of RSM to store, manage and search the meaning units...
The paper addresses the problem of XML document adaptation - transforming a document valid against an old version of an XML schema to a document valid against the new version of the schema. We propose a solution using a conceptual model, where the relationships between the old and new versions are specified declaratively. We focus on those scenarios, where mere between the structures of the schemas...
In order to parse GML data more effectively and accurately, the homologous regular expression (abbreviated to HRegExp) which is a powerful grammar tool for recognizing strings of text is put forward. HRegExp is generated from the regular expression by rational extension and reconstruction. the syntax structure and elements internal organization of simple data type and complex data type in GML schemas...
In healthcare there are perceived benefits in the integration of multi-institutional patient data. The use of multiagent systems may facilitate the discovery and retrieval of patient data from the multiple health institutions that the patient has come into contact with. The main objective of this work is to define an architecture that allows agents to seek and collect health data from an HL7 based...
