Mediators in the architecture of future information systems

by Gio Wiederhold - IEEE COMPUTER , 1992
"... The installation of high-speed networks using optical fiber and high bandwidth messsage forwarding gateways is changing the physical capabilities of information systems. These capabilities must be complemented with corresponding software systems advances to obtain a real benefit. Without smart softw ..."

-level functional partitioning. These partitions are mapped into information process-ing modules. The modules are assigned to nodes of the distributed information systems. A central role is assigned to modules that mediate between the users ' workstations and data re-sources. Mediators contain

RSVP: A New Resource Reservation Protocol

by Lixia Zhang, Stephen Deering, Deborah Estrin, Scott Shenker, et al. , 1993
"... Whe origin of the RSVP protocol can be traced back to 1991, when a team of network researchers, including myself, started playing with a number of packet scheduling algorithms on the DARTNET (DARPA Testbed NETwork), a network testbed made of open source, workstation-based routers. Because scheduling ..."

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 ..."

CQ is scalable, we have also employed other techniques including incremental evaluation of continuous queries, use of both pull and push models for detecting heterogeneous data source changes, and memory caching. This paper presents the design of NiagaraCQ system and gives some experimental results on the system

Extracting patterns and relations from the world wide web

by Sergey Brin - In WebDB Workshop at 6th International Conference on Extending Database Technology, EDBT’98 , 1998
"... Abstract. The World Wide Web is a vast resource for information. At the same time it is extremely distributed. A particular type of data such as restaurant lists may be scattered across thousands of independent information sources in many di erent formats. In this paper, we consider the problem of e ..."

DBpedia -- A Crystallization Point for the Web of Data

by Christian Bizer , Jens Lehmann , Georgi Kobilarov , Sören Auer , Christian Becker , Richard Cyganiak , Sebastian Hellmann , 2009
"... The DBpedia project is a community effort to extract structured information from Wikipedia and to make this information accessible on the Web. The resulting DBpedia knowledge base currently describes over 2.6 million entities. For each of these entities, DBpedia defines a globally unique identifier ..."

that can be dereferenced over the Web into a rich RDF description of the entity, including human-readable definitions in 30 languages, relationships to other resources, classifications in four concept hierarchies, various facts as well as data-level links to other Web data sources describing the entity

Efficient power control via pricing in wireless data networks

by Cem U. Saraydar, Narayan B. M, Senior Member, David J. Goodman - IEEE Trans. on Commun , 2002
"... Abstract—A major challenge in the operation of wireless communications systems is the efficient use of radio resources. One important component of radio resource management is power control, which has been studied extensively in the context of voice communications. With the increasing demand for wir ..."
Abstract - Cited by 339 (8 self) - Add to MetaCart
for wireless data services, it is necessary to establish power control algorithms for information sources other than voice. We present a power control solution for wireless data in the analytical setting of a game theoretic framework. In this context, the quality of service (QoS) a wireless terminal receives

Improving MapReduce Performance in Heterogeneous Environments

by Matei Zaharia, Andy Konwinski, Anthony D. Joseph, Randy Katz, Ion Stoica , 2008
"... MapReduce is emerging as an important programming model for large-scale data-parallel applications such as web indexing, data mining, and scientific simulation. Hadoop is an open-source implementation of MapReduce enjoying wide adoption and is often used for short jobs where low response time is cri ..."

Impact of network density on Data Aggregation in wireless sensor networks

by Chalermek Intanagonwiwat, Deborah Estrin , Ramesh Govindan , John Heidemann , 2001
"... In-network data aggregation is essential for wireless sensor networks where resources (e.g., bandwidth, energy) are limited. In a previously proposed data dissemination scheme, data is opportunistically aggregated at the intermediate nodes on a low-latency tree which may not necessarily be energy ef ..."

Protecting Privacy when Disclosing Information: k-Anonymity and Its Enforcement through Generalization and Suppression

by Pierangela Samarati, Latanya Sweeney , 1998
"... Today's globally networked society places great demand on the dissemination and sharing of person-specific data. Situations where aggregate statistical information was once the reporting norm now rely heavily on the transfer of microscopically detailed transaction and encounter information. Thi ..."
