The Web offers a unique opportunity for State Departments of Transportation and planning agencies to disseminate to large audience interactive results of transportation studies. This paper provides a technical backgrounder about the differences between GIS desktop applications and web mapping applications in the context of transportation planning. In a web mapping application the application se...

Requirements engineering is highly challenging particularly when designing innovative software products. This is so because there are no corresponding products, ultimate needs of actors are difficult to capture, the products may have unforeseeable impacts on the actors’ behavior, and it is hard to find out how value-added and competitive the product actually is. In this paper, we propose a nove...

Ontology-based knowledge management systems enable the automatic discovery, sharing and reuse of structured data sources on the semantic web. With the emergence of multilingual ontologies, accessing knowledge across natural language barriers has become a pressing issue for the multilingual semantic web. In this paper, a semantic-oriented cross-lingual ontology mapping (SOCOM) framework is propo...

Ontologies as means for conceptualizing and structuring domain knowledge within a community of interest are seen as a key to realize the Semantic Web vision. However, the decentralized nature of the Web makes achieving this consensus across communities difficult, thus, hampering efficient knowledge sharing between them. In order to balance the autonomy of each community with the need for intero...

Improve the quality of web service composition using the petri nets and ontology. Previously web services are design independently. These kinds of services are not compatible. We observe the different security issues. Now in this paper we design new semantic web networks using petri nets and ontology. Start the interaction process levels display the decisions using colored petri nets environmen...

The Semantic Web is rapidly becoming a defacto distributed repository for semantically represented data, thus leveraging on the added on value of the network effect. Various ontology mapping techniques and tools have been devised to facilitate the bridging and integration of distributed data repositories. Nevertheless, ontology mapping can benefit from human supervision to increase accuracy of ...

Exposure to particulate matter (PM) in ambient air leads to adverse health effects. To design cost effective mitigation strategies, a thorough understanding of the sources of particulate matter is crucial. We have successfully generated a web map service that allows to access information on fuel dependent health effects due to particulate matter. For this purpose, the LOTOS-EUROS air pollution ...

This poster investigates problems and solutions for searching the Web for geospatial data produced by various levels of government. Currently, geospatial data to meet particular needs are difficult to find. We suggest using Internet DBMS and Semantic Web technology to improve search techniques over metadata by using context-oriented search phrases, full query expressions, and semantic mappings....

We examine the use of semantic web resources in robot navigation; more specifically, in qualitative navigation where uncertain reasoning plays a significant role. We propose a framework for robot navigation that connects existing semantic web resources based on probabilistic description logics, with probabilistic relational learning and planning. We show the benefits of this framework in a real...
