Semantic Web Breakthrough: TopQuadrant Claims World's First Tool Supporting Multiple Reasoning Engines

TopBraid Composer 2.0 moves the ultimate promise of Semantic Web solutions closer to reality

TopQuadrant - the company for which AJAXWorld 2007 East speaker Dean Allemang (pictured) works as a Semantic Web consultant - has announced the succesful development of what it claims is "the only commercially-ready ontology design environment that meets the needs of application developers who are building scalable applications for consumers and enterprises" - enabling software applications to organize and process information, thus making the web 'smarter' for people and machines.

TopBraid Composer 2.0, says the company, allows users to select from a catalog of available inference (reasoner) engines and execute the reasoners in a specified order.  Users can run SPARQL queries or rules on top of a description logic reasoner.

Allemang is a long-time traveller in knowledge science. He was awarded his PhD in AI in 1990, worked at five different AI labs in Europe between 1990-1996, and co-founded a company in the mid-90s that tried to invent the Semantic Web when the standards were just a gleam in the eye of a few W3C folks.

As a consultant for TopQuadrant he is the one running the training course, but he learns more from the students than they ever guess, he saus.

His laptop is full of Semantic Web software, and he even knows how to use more than half of it. "It's an exciting time," says Allerman, "for those of us who have been fans of abstraction for the past three decades."

Allemang's session at AJAXWorld 2007 East is called "Using RDFa to Build Semantic Mash-ups." Semantic Mash-ups ("SMash-ups" for short) are combinations of information from multiple sources using the W3C Semantic Web languages (RDF and OWL) to control merging and filtering of the mashed-up data.

Allemang will present a system for building Smash-ups from many different kinds of Web sources, including RDF source, databases, and Web pages (via RDFa, the RDF in HTML proposal).

这个⋯⋯突破意义何在?

现在的reasoner是单独使用的,比如你想换一种推理规则,就要用另一个reasoner。我想上面说的是,他们实现了几个reasoner的组合使用,这样就更加灵活了。便于商业应用。主要的难点应该是在解决reasoner相互的一致性。

为什么这就是突破了……

应该是种突破。试想一下如果面对成百上千个需求各异的用户,是否要定义成百上千个reasoner。如果定义了基本的reasoner,然后基本的可以根据需要组合成更复杂的,就大大提高了商用灵活性。

reasoner不是指FaCT、Racer之类的推理机吗?
一个推理机应该可以完成多种不同的推理任务吧
不同推理机之间差别在哪呢?
