The singer's information is essential in organizing, browsing and retrieving music collections. In this technical report, a system for automatic singer identification is developed which recognizes the singer of a song by analyzing the music signal. Meanwhile, songs which are similar in terms of singer's voice are clustered. The proposed scheme follows the(More)

Optimal paths computed by conventional path-planning algorithms are usually not " optimal " since realistic traffic information and local road network characteristics are not considered. We present a new experiential approach that computes optimal paths based on the experience of taxi drivers by mining a huge number of floating car trajectories. The(More)
This paper presents a new framework for Grid-enabled GIService web portals to facilitate the building of high-level intelligent Internet GIServices. The five-tier architecture suggested here can support advanced semantic search and query functions for distributed GIServices by combining Grid computing, Semantic Web, and software agent technologies. The(More)
—A reliable and accurate short-term traffic forecasting system is crucial for the successful deployment of any Intelligent Transportation System. To address the complexity of real-world traffic forecasting conditions, this paper presents a layered traffic forecasting algorithm, which is implemented by a clustering neural network, Kohonen Self-Organizing Map(More)
This article discusses how Participatory GIS (PGIS) can be improved by applying current start-of-the-art computing technologies, in particular high performance computing technology. The discussion covers the methods and tools for the four types of space-time collaboration situations (different place/time). While the four types are all addressed, the focus(More)
This paper introduces a design framework for developing GIService web portals which are supported by Grid computing and Service-Oriented Architecture. A GIS web portal can be enhanced by Grid computing technologies to improve its performance, usability and security. The loosely-coupled Internet GIServices can be combined and integrated by implementing(More)
Current map generalization for massive spatial data is becoming more and more urgent. It is necessary to study the integration of new technologies, such as distributed computing, which is important to provide high-quality geographic information services. This paper proposes an architecture of automated map generalization in istributed environments, and(More)
