  <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>

environments such as those enabled by the semantic web and pervasive computing technologies. The presence of heterogeneous entities that
are neither pre-determined nor permanent, and the lack of central

policies address this problem while maintaining openness and

  <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[A knowledge base can be thought of as a special kind of database for knowledge management. It provides the means for computerized collection, organization and retrieval of knowledge. Due to growth in deployment of sensors, we encounter many scenarios where data is constantly flowing between sensors and applications. The volume of data produced is large, so is the rate of the data-flow. In such scenarios, knowledge extraction boils down to finding useful information i.e. detecting events of in...]]></description>

  <description><![CDATA[We describe RDF123, a highly flexible open-source tool for transforming spreadsheet data to RDF. Existing spreadsheet-to-RDF tools typically map only to star-shaped RDF graphs, i.e. each spreadsheet row is an instance, with each column representing a property. RDF123, on the other hand, allows users to define mappings to arbitrary graphs, thus allowing much richer spreadsheet semantics to be expressed.  Further, each row in the spreadsheet can be mapped with a different RDF/OWL scheme. ...]]></description>

  <description><![CDATA[Specialized stores for RDF data are essential parts of many
Semantic Web applications. Current RDF stores have primarily
focused on efficiently storing and querying large volumes
of data and little attention has been given other features
common to many database systems, including how information
can updated and maintained or access to data
controlled. The problem is complicated by the fact that the
addition or deletion of a simple fact (i.e., an RDF triple) are

  <description><![CDATA[Semantic Web languages are being used to represent, encode and
exchange semantic data in many contexts beyond the Web -- in
databases, multiagent systems, mobile computing, and ad hoc networking
environments.  The core paradigm, however, remains what we call the
{em Web aspect} of the Semantic Web -- its use by independent and
distributed agents who publish and consume data on the World Wide Web.
To better understand this central use case, we have harvested and

finding all supporting sources and rejecting all irrelevant ones, but
neither RDF document nor triple is appropriate. Therefore, we approach
this goal using lossless decomposition of RDF graph at RDF molecule

However, the appropriate level of granularity for tracking provenance of RDF graph remains in debate. RDF document is too coarse since it could contain irrelevant information.

  <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.

It provides the means for computerized collection, organization and retrieval

where data is constantly flowing between sensors and applications. The volume of data
produced is large, so is the rate of the data-flow. In such scenarios, knowledge extraction

  <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>

approach encompasses a set of principles

Its utility depends on three issues: availability (existence of data), accessibility (users can retrieve the data they want), and quality (users can judge the quality of the retrieved data). While more data are available in the Semantic Web, the latter two issues are often ignored or circumscribed due to lacking of tools and mechanisms.

  <description><![CDATA[Peter Patel-Schneider gave a talk on the Semantic Web at Google several weeks ago and you can see the video here.  The abstract:

"The Semantic Web has been attracting considerable attention the last few years. From the point of view of Knowledge Representation, the Semantic Web affords opportunities for both research and application. However, several aspects of the Semantic Web, as it has been envisioned, cause problems from the Knowledge Representation viewpoint. Overcoming some of these ...]]></description>

  <description><![CDATA[Yesterday we posted directions on how to tell if your Semantic Web document is in Swoogle's database.  Unfortunately, our directions suggested using a service that, if called outside our firewall, requires a Swoogle API key.  (This is seperate from being a registered Swoogle user.)  We didn't notice at first, because we were inside the firewall when we tested it.   When we did, we deleted the post, but PlanetRDF had already picked up the post and it was still in our database.  We're working t...]]></description>

Foaf is a well-known semantic web practice on the Web, and we know that there are millions of FOAF instances on the Web. A scutter can help use to recursively find foaf documents online using hyperlinks in foaf documents; however, how to obtain the initial seeds is still a big issue.

In addition,  many semantic web users would like to find out the population of ontology, e.g. the instances of a defined class such as foaf:Person, or where foaf:email...]]></description>

  <description><![CDATA[If you go to Swoogle on this Groundhog's Day you will see a change.  We've released a new version, Swoogle 2006, that is a nearly complete rewrite of  Swoogle Classic, which now answers to Swoogle 2005. While Swoogle is currently missing some of Swoogle 2005's features, it enjoys a cleaner and simpler model and foundation.  We will be adding in some of these features as well as new ones over the next few months. Here are some of Swoogle 2006's highlights:

Replies are sent to the whole group.  We're not exactly sure what Swooglers will have to talk about, but it might be a place to share your experiences in using Swoogle, ask other users for advice, etc.]]></description>

  <description><![CDATA[The W3C's RDF-in-HTML task force has been wrestling with the problem developing recommended ways to embed RDF content in XHTML documents.  I think that this is incredibly important as many of the use cases for the Semantic Web can benefit from documents that have both human and machine readable portions.  RDF-in-HTML is actually a joint task force of the Semantic Web Best Practices and Deployment and HTML  Working Groups. Last week, the task force released a new version of the primer on  RDF/...]]></description>

  <description><![CDATA[Recently ClĂˇudio Fernandes asked on several semantic web mailing lists

"Can someone point me to some huge owl/rdf files?  I'm writing a owl parser with different tools, and I'd like to benchmark them all with some really really big files."

I just ran some queries over Swoogle's collection of 850K RDF documents collected from the web.  Here are the 100 largest RDF documents and OWL documents, respectively.  Document size was measured in terms of the number of triples.  For this query, a...]]></description>
