Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - A disaster is the impact of natural or man-made hazard and all the disasters require mitigation measures. Current Disaster Management Systems are dependent upon manual data entry, analysis, and decision making. Semantic Web technologies have actively been used for the development of intelligent and self governed web based system. These systems include the use of XML, RDF and ontologies for formulation and semantic interpretation of data. The ontology defines rules essential to search the data from unstructured world i.e., World Wide Web, which are later used for information extraction and reasoning purpose. Various disasters related ontologies have been considered but none conceptualizes the domain completely. Most of the ontologies are designed for the specific purpose in the domain like the disaster plans, the task ontology for the emergency operation center. We have developed disaster ontology which almost covers every important aspect of disasters like disaster type, disaster date, losses including human loss as well as infrastructure loss, services, service providers, disaster location, and relief items etc.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - For the management of disasters, the use of Natural Language Processing (NLP) for the extraction of facts is in its early stages. Some of the systems are being developed but they are not addressing the specific problem of disaster management. Most of the available online disaster management systems do not employ the semantic technologies of automatically converting the data into information and are dependent on manual input. In this research work a new approach for implementation of disaster management system is proposed, implemented and evaluated. The developed system searches for the disaster related data from the unstructured world and extracts the disaster related information from that data. An ontology based crawler is responsible to search for the URLs containing the required data. This data is then passed for the Information extraction. So, the main focus of this work is on the development of system that can extract the disaster related information from text resources.…
