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.

The W3C Rule Interchange Format (RIF) Working Group has published six Candidate 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:

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.
