BACKGROUND The presenting features and clinical course of biomass smoke induced bronchial anthracofibrosis (BAF) are not well known. PATIENTS AND METHODS 333 patients who had a history of long-term exposure to biomass smoke, having BAF confirmed by a bronchoscopy from January 1998 to December 2004, were included in this study. The clinical features,(More)
Most information retrieval systems, including Web search engines, use similarity ranking algorithms based on a vector space model to find relevant information in response to a user's request. However, the retrieved information is frequently irrelevant, because most of the current information systems employ index terms or other techniques that are variants(More)
A primary goal of this project is to design, develop, test, enhance, and integrate techniques and mechanisms for specifying the semantic content in units of multimedia information. By the semantic content of a multimedia object O, we refer to the meaning-based categories into which O may be classified, such as " students " , " research projects " , and "(More)
The DBMS performance might change by allocating resources and by performing a specific kind of workload. Database administrators should be able to identify relative resources that can change DBMS performance in order to effectively manage database systems. This paper aims to identify the relative resources that can affect the DBMS performance depending on(More)
The primary goal of this project is to design, develop, deploy, and test methodologies for exploiting semantic aspects of the data. Toward this end, we have developed an information system based on ontologies (collections of key concepts and terms along with their interrelationships) to provide intelligent information selection. The main capabilities of the(More)

The primary goal of this project is to design, develop, and test methodologies for exploiting semantic aspects of the multimedia earthquake science data. The nature of data in the earthquake science domain is full of variety. That is, the interpretations of data differ from resource to resource and scientist to scientist. Therefore, our system must provide(More)
