Ontology Learning for the Semantic Web

by Er Maedche, Steffen Staab - IEEE Intelligent Systems , 2001
"... The Semantic Web relies heavily on the formal ontologies that structure underlying data for the purpose of comprehensive and transportable machine understanding. Therefore, the success of the Semantic Web depends strongly on the proliferation of ontologies, which requires fast and easy engineering o ..."

Web Server Workload Characterization: The Search for Invariants (Extended Version)

by Martin F. Arlitt, Carey L. Williamson , 1996
"... The phenomenal growth in popularity of the World Wide Web (WWW, or the Web) has made WWW traffic the largest contributor to packet and byte traffic on the NSFNET backbone. This growth has triggered recent research aimed at reducing the volume of network traffic produced by Web clients and servers, b ..."

, by using caching, and reducing the latency for WWW users, by using improved protocols for Web interaction. Fundamental to the goal of improving WWW performance is an understanding of WWW workloads. This paper presents a workload characterization study for Internet Web servers. Six different data sets

ANALYSIS OF WIRELESS SENSOR NETWORKS FOR HABITAT MONITORING

by Joseph Polastre, Robert Szewczyk, Alan Mainwaring, David Culler, John Anderson , 2004
"... We provide an in-depth study of applying wireless sensor networks (WSNs) to real-world habitat monitoring. A set of system design requirements were developed that cover the hardware design of the nodes, the sensor network software, protective enclosures, and system architecture to meet the require ..."

present a set of experiences from a four month long deployment on a remote island. We analyze the environmental and node health data to evaluate system performance. The close integration of WSNs with their environment provides environmental data at densities previously impossible. We show that the sensor

NiagaraCQ: A Scalable Continuous Query System for Internet Databases

by Jianjun Chen, David J. Dewitt, Feng Tian, Yuan Wang - In SIGMOD , 2000
"... Continuous queries are persistent queries that allow users to receive new results when they become available. While continuous query systems can transform a passive web into an active environment, they need to be able to support millions of queries due to the scale of the Internet. No existing syste ..."

A Hierarchical Internet Object Cache

by Anawat Chankhunthod , Peter B. Danzig, Chuck Neerdaels, Michael F. Schwartz, Kurt J. Worrell - IN PROCEEDINGS OF THE 1996 USENIX TECHNICAL CONFERENCE , 1995
"... This paper discusses the design andperformance of a hierarchical proxy-cache designed to make Internet information systems scale better. The design was motivated by our earlier trace-driven simulation study of Internet traffic. We believe that the conventional wisdom, that the benefits of hierarch ..."

of hierarchical file caching do not merit the costs, warrants reconsideration in the Internet environment. The cache implementation supports a highly concurrent stream of requests. We present performance measurements that show that the cache outperforms other popular Internet cache implementations by an order

Measuring Bottleneck Link Speed in Packet-Switched Networks

by Robert L. Carter, Mark E. Crovella - PERFORMANCE EVALUATION , 1996
"... The quality of available network connections can often have a large impact on the performance of distributed applications. For example, document transfer applications such as FTP, Gopher and the World Wide Web suffer increased response times as a result of network congestion. For these applications, ..."

Ontology Mapping: The State of the Art

by Yannis Kalfoglou, Marco Schorlemmer , 2003
"... Ontology mapping is seen as a solution provider in today's landscape of ontology research. As the number of ontologies that are made publicly available and accessible on the Web increases steadily, so does the need for applications to use them. A single ontology is no longer enough to support t ..."

the tasks envisaged by a distributed environment like the Semantic Web. Multiple ontologies need to be accessed from several applications. Mapping could provide a common layer from which several ontologies could be accessed and hence could exchange information in semantically sound manners. Developing

Internet web servers: Workload characterization and performance implications

by Martin F. Arlitt, Carey L. Williamson - IEEE/ACM Transactions on Networking , 1997
"... This paper presents a workload characterization study for Internet Web servers. Six different data sets are used in the study: three from academic environments, two from scientific research organizations, and one from a commercial Internet provider. These data sets represent three different orders o ..."

The WSLA framework: Specifying and monitoring service level agreements for web services

by Alexander Keller, Heiko Ludwig - JOURNAL OF NETWORK AND SYSTEMS MANAGEMENT , 2003
"... We describe a novel framework for specifying and monitoring Service Level Agree-ments (SLA) for Web Services. SLA monitoring and enforcement become increasingly important in a Web Service environment where enterprise applications and services rely on services that may be subscribed dynamically and o ..."

Although WSLA has been designed for a Web Services environment, it is applicable as well to any inter
