envinment that they call "Task Computing Environment" (TCE) that uses
standard Semantic Web (RDF, OWL, DAML-S) and Web Services (SOAP, WSDL)
technology to define, disconver, compose and deliver services.  Their

Users need better ways to explore linked open data collections and obtain information from it. Using SPARQL requires not only mastering its syntax and semantics but also understanding the RDF data model, the ontology used by the DBpedia, and URIs for entities of interest.  Natural language question answering systems solve the problem, but these are still subjects of research. We are developing a compromise approach in which non-experts specify a graphical ``skeleton'' for a query and anno...]]></description>

  <description><![CDATA[The past few years have seen significant work in mobile data management, typically based on the client/proxy/server model. Mobile/wireless devices are treated as clients that are data consumers only, while data sources are on servers that typically reside on the wired network. With the advent of pervasive computing environments, an alternative scenario arises where mobile devices gather and exchange data from not just wired sources, but also from their ethereal environment and one another.

  <description><![CDATA[RDF123 is an application and web service for converting data in simple spreadsheets to an RDF graph.  Users control how the spreadsheet's data is converted to RDF by constructing a graphical RDF123 template that specifies how each row in the spreadsheet is converted as well as metadata for the spreadsheet and its RDF translation.  The template can map spreadsheet cells to a new RDF node or to a literal value. Labels on the nodes in the map can be used to create blank nodes or labeled nodes, a...]]></description>

  <description><![CDATA[The Semantic Web was designed to unambiguously define and use ontologies to encode data and knowledge on the Web. Many people find it difficult, however, to write complex RDF statements and queries because it requires familiarity with the appropriate ontologies and the terms they define. We describe a framework that eases the experiences in authoring and querying RDF data, in which we focus on automatically finding a set of appropriate Semantic Web ontology terms from a set of words used as t...]]></description>

  <description><![CDATA[A growing number of e-businesses have been using XML schemas in recent years. Schema mapping now plays a crucial role in integrating heterogeneous ebusiness applications. Since large-scale XML schema mapping using complex and hybrid similarity measures requires significant amount of processing time, a sophisticated similarity analysis algorithm is needed to handle its complexity and performance. In this paper, we focus on designing a service-oriented architecture (SoA) for schema mapping, bas...]]></description>

Further, each row in the spreadsheet can be mapped with a fairly different RDF scheme. Two i...]]></description>

This process is generally template driven, device centric, limited in its expressibility, time consuming and error prone which can lead to configurations where policies are violated or there are unintended consequences that are difficult to detect and resolve. In this paper, we propose an alternate mechanism for policy based network...]]></description>

  <description><![CDATA[OWL (the Web Ontology Language) and the related RDF (Resource Description Framework) are XML-based languages designed to represent the semantics of data. These languages enable systems to go beyond simple controlled vocabularies and specify the contexts and logical relationships among terms. Formal ontologies use classes (e.g., Species A) and properties (e.g., is a member of, or eats, or has body mass) to represent concepts and relationships as assertions. For example, two assertions might be...]]></description>

  <description><![CDATA[The Semantic Web was invented by Tim Berners-Lee in 1998 as a web of data for machine consumption. Its applicability in supporting real world applications on the World Wide Web, however, remains unclear to this day because most existing works treat the Semantic Web as one universal RDF graph and ignore the Web aspect. In fact, the Semantic Web is distributed on the Web as a web of belief: each piece of Semantic Web data is independently published on the Web as a certain agent's belief instead...]]></description>

  <description><![CDATA[We examine the intersection of data mining and semantic web in this paper. We briefly identify some points where they can impact one another, and then develop a specific example of intrusion detection, an application of distributed data mining. We have produced an ontology specifying a model of computer attacks. Our model is based upon an analysis of over 4,000 classes of computer attacks and their corresponding attack strategies using data derived from CERT/CC advisories and NIST’s ICAT me...]]></description>

  <description><![CDATA[Service matching is one of the crucial elements in the success of large, open agent systems. While finding "perfect" matches is always desirable, it is not always possible. The capabilities of an agent may change over time; some agents may be unwilling to, or unable to communicate their capabilities at the right level of details. The solution we propose is to have the broker agent dynamically refine the agent’s capability model and to conduct performance rating. The agent capability model w...]]></description>

from manually configuring and instructing computer systems. As the general
trend of computing is progressing towards an open and dynamic infrastructure,
building context-aware systems can be difficult and costly. In order to build

  <description><![CDATA[The FOAF (Friend of a Friend) vocabulary has become one of the most used semantic web ontologies and can be found in millions of RDF documents on the web. FOAF is used to describe basic attributes of people and relationships among them.

foafPub is a dataset of information extracted from FOAF files
collected during the Fall of 2004.  The data represents 7118 foaf
documents collected from 2044 sites (identified by their symbolic IP
address). A total of 201,612 RDF triples with provenance ...]]></description>

  <description><![CDATA[A vast amount of information is encoded in tables on the web, spreadsheets and databases. Considerable work has been focused on exploiting unstructured free text; however techniques that are effective for documents and free text do not work well with tables. Early work in table interpretation in the field of document analysis and later on the Web, focused mainly on understanding and extracting tables from scanned documents and html web pages. Relatively little work has addressed the understan...]]></description>

  <description><![CDATA[Users need better ways to explore linked open data collections and obtain information from it. Using SPARQL requires not only mastering its syntax and semantics but also understanding the RDF data model, the ontology used by the DBpedia, and URIs for entities of interest. Natural language question answering systems solve the problem, but these are still subjects of research. We are developing a compromise approach in which non-experts specify a graphical “skeleton” for a query and annotat...]]></description>

Abstract: 
The Semantic Web language RDF was designed to unambiguously define and use ontologies to encode data and knowledge on the Web. It is difficult, however, to write complex RDF statements and queries because doing so requires familiarity with the appropriate ontologies and the terms they define. While ontologies have been developed for various branches of the sciences, their use remains limited. We describe ...]]></description>

  <description><![CDATA[The Semantic Web language RDF was designed to unambiguously define and use ontologies to encode data and knowledge on the Web. Many people find it difficult, however, to write complex RDF statements and queries because doing so requires familiarity with the appropriate ontologies and the terms they define. We describe a system that suggests appropriate RDF terms given semantically related English words and general domain and context information. We use the Swoogle Semantic Web search engine t...]]></description>

It is also, in part, a re-branding of the semantic web itself, with less emphasis on semantics, and more on RDF linkages amongst data sources. Also heavily emphasized is the proper role of web architecture (http requests and responses; 303 redirects; etc.), and the distinction between information resources (those that physically reside on the web), and non-information resources (those that exist in t...]]></description>

  <description><![CDATA[At the present time, Bayesian networks (BNs), presumably the most popular uncertainty inference framework, are still widely used as standalone systems. When the problem itself is distributed, domain knowledge has to be centralized and unified before a single BN can be created. Alternatively, separate BNs describing related sub-domains or different aspects of the same domain may be created, but it is difficult to combine them for problem solving even if the interdependent relations between var...]]></description>
