TBox 与ABox
caleon 发表于 2006-3-6 19:43:24

TBox存放的是一些结点以及结点之间的关系,而ABox存放的就是这些结点或则关系具体的实例。类似于类,以及对象的关系。

对语义网的一点理解
caleon 发表于 2006-3-6 19:32:22

 其实我们现在所构造的语义网无非就是对客观世界的一种抽象,与面向对象的方法稍有不同的是它将客观世界抽象为概念,以及概念之间的关系。而面向对象的方法则将客观世界抽象为一系列的对象,相比较概念而言更加抽象。然后根据这些概念和关系构造更加复杂的概念和关系。最后形成一个概念和关系的层次网络。"计算机可理解"就是计算机根据一系列的规范来对这些概念和关系进行推理,以进一步发现其中内在的逻辑和关系。    感觉现在的所谓的DL完全是借用离散数学中的概念和定义。没有什么创新之处。难道非要等基础数学发展才行?!

匹配引擎应该具有的特点
caleon 发表于 2006-3-4 20:24:44

the matching engine must satify the following desiderate:
匹配引擎必须满足以下的要求:
the matching engine should support flexible semantic matching between advertisments and requests on the basis of the ontologies availble to the servies and the matching engine
首先在基于可以利用的本体的基础上的匹配的灵活性 despite the flexibility of match,the matching engine should minimize false positives and false negatives.
Furthermore,the requesting sevice should have some control
on the amount of matching flexibi


服务profiles 和model的区别
caleon 发表于 2006-3-4 15:41:14

The Process Model and the Profile provide two different points view of the same Web Service.the profile specifies the capabilities of the Web service(what the Web service does),while the process model provides a declarative sepecification of how the Web service achieves its goals,and how its requesters can interact with it. for ex,the Profile says that a Web service ,say amzon's sells books,the Process Model says that in order to buy books the requester needs to find the book,and provide pa


OWL-S 中的IOPE的例子
caleon 发表于 2006-3-4 15:17:25

a for-pay news reporting service might require as inputs a date and a credit card number;have as a precondition that the credit card number is  a valid one and not overdrawn;have as output a web page with news of that day,and have the effect that the specified credit card is charged. 讲述的就是一个订阅付费新闻 的例子。 其中的inputs就是credit card number,preconditions是卡号必须是有效的 output 就是你会收到订阅的新闻,产生的effect就是卡上的费用被扣除了


Semantic request and response for standardized Web services
caleon 发表于 2006-2-20 21:27:21

Since WSDL may contain embedded Web services or share the common object data types within more than one Web service, while the meaning and content of the data and services cannot be described, WSDL is a puzzle to the application developers who deploy Web services into their own applications. Anticipating the enormous growth of Web services by different service providers in the near future, it is difficult for application developers to track and understand the different routines for invoking

  论文这两天还是没什么着落,先看看国外的关于semantic web services的动态再说,争取最近个把月有自己的想法。   周末了,大家商量着去给老板拜年,呵呵,跟着去凑合。   另外也思考一下今年的安排,争取5月份论文发表,六,七月份写论文,今年毕业
