Rule Interchange Format (RIF) Advances to W3C Proposed Recommendation

By   /  May 12, 2010  /  Uncategorized  /  No Comments

The Rule Interchange Format (RIF) Working Group has published six Proposed Recommendations. Together, they allow systems using a variety of rule languages and rule-based technologies to interoperate with each other and with Semantic Web technologies.

Three of the drafts define XML formats with formal semantics for storing and transmitting rules:

Building Competency in Semantic Web Technology

By   /  December 1, 2009  /  Data Blogs | Information From Enterprise Leaders, Data Education, Smart Data Blogs, Smart Data News, Articles, & Education  /  No Comments

 In part I of this two-part series, Dean Allemang & Scott Henninger draw on years of teaching TopQuadrant’s introduction course on the Semantic Web to make some observations on teaching Semantic Web concepts to a wide variety of students.


Whenever we learn something new, there is a tendency to relate it to things we already know.  This is how we bring our experience to bear on new things; the better we can apply what we already know, the more quickly we can come up to speed on new things.   But when it comes to learning a new technology, this tendency can also be a handicap.  A new technology is only interesting if it does something different from existing technologies.  Viewing everything as an old trick in new clothing conceals exactly the interesting aspects of a new technology.

The Semantics of Meaningful XML Keyword Search Using SQL

By   /  April 14, 2009  /  Data Articles | Data Science, Business Intelligence, & More  /  No Comments

Executive Summary
  

XML Keyword Search is still a popular academic subject. It has not reached or been recognized by XML and Internet commercial products yet. The concepts involved are also very important to the semantic web. The semantics industry today with its work on higher level semantics like ontologies and taxonomies has overlooked the importance of utilizing the semantics of hierarchical structured data like XML. When working with hierarchically structured data, the first level of handling semantic understanding must be recognizing the hierarchical structure and its (lower level) hierarchical semantics. This is then used to eliminate false keyword search results that can show up as matches in hierarchical structures; otherwise they will go undetected to the higher level semantic processing which will also not detect them since they are not concerned with the structure of the data. This will cause unmeaningful results to be returned.
