PROMPT: Algorithm and Tool for Automated Ontology Merging and Alignment

by Natalya Fridman Noy, Mark A. Musen , 2000
"... Researchers in the ontology-design field have developed the content for ontologies in many domain areas. Recently, ontologies have become increasingly common on the WorldWide Web where they provide semantics for annotations in Web pages. This distributed nature of ontology development has led t ..."

The Ontolingua Server: a Tool for Collaborative Ontology Construction

by Adam Farquhar, Richard Fikes, James Rice - International Journal of Human-Computer Studies , 1996
"... Reusable ontologies are becoming increasingly important for tasks such as information integration, knowledge-level interoperation, and knowledgebase development. We have developed a set of tools and services to support the process of achieving consensus on common shared ontologies by geographically ..."

distributed groups. These tools make use of the worldwide web to enable wide access and provide users with the ability to publish, browse, create, and edit ontologies stored on an ontology server. Users can quickly assemble a new ontology from a library of modules. We discuss how our system was constructed

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

Ontologies are us: A unified model of social networks and semantics

by Peter Mika - In International Semantic Web Conference , 2005
"... Abstract. On the Semantic Web ontologies are most commonly treated as artifacts created by knowledge engineers for a particular community. The task of the engineers is to forge a common understanding within the community and to formalize the agreements, prerequisites of reusing domain knowledge in i ..."

Tor: The secondgeneration onion router,”

by Roger Dingledine - in 13th USENIX Security Symposium. Usenix, , 2004
"... Abstract We present Tor, a circuit-based low-latency anonymous communication service. This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, an ..."

, and efficiency. We briefly describe our experiences with an international network of more than 30 nodes. We close with a list of open problems in anonymous communication. Overview Onion Routing is a distributed overlay network designed to anonymize TCP-based applications like web browsing, secure shell

Simulation, verification, automated composition of web services

by Srini Narayanan, Sheila A. Mcilraith - In WWW , 2002
"... Web services-- Web-accessible programs and devices – are a key application area for the Semantic Web. With the proliferation of Web services and the evolution towards the Semantic Web comes the opportunity to automate various Web services tasks. Our objective is to enable markup and automated reason ..."

reasoning technology to describe, simulate, compose, test, and verify compositions of Web services. We take as our starting point the DAML-S DAML+OIL ontology for describing the capabilities of Web services. We define the semantics for a relevant subset of DAML-S in terms of a first-order logical language

A software framework for matchmaking based on semantic web technology

by Lei Li, Ian Horrocks , 2003
"... An important objective of the Semantic Web is to make Electronic Commerce interactions more flexible and automated. To achieve this, standardisation of ontologies, message content and message protocols will be necessary. In this paper we investigate how Semantic and Web Services technologies can be ..."
