Web-Based Information Extraction Technology

Information extraction techniques on the Web are the current research hotspot. Now many information extraction techniques based on different principles have appeared and have different capabilities. We classify the existing information extraction techniques by the principle of information extraction and analyze the methods and principles of semantic information adding, schema defining,rule expression, semantic items locating and object locating in the approaches. Based on the above survey and analysis,several open problems are discussed.

Discovering Frequent Subtrees from XML Data Using Neural Networks

By rapid progress of network and storage technologies, a huge amount of electronic data such as Web pages and XML has been available on Internet. In this paper, we study a data-mining problem of discovering frequent ordered sub-trees in a large collection of XML data, where both of the patterns and the data are modeled by labeled ordered trees. We present an efficient algorithm of Ordered Subtree Miner （OSTMiner） based on two- layer neural networks with Hebb rule, that computes all ordered sub-trees appearing in a collection of XML trees with frequent above a user-specified threshold using a special structure EM-tree. In this algo- rithm, EM-tree is used as an extended merging tree to supply scheme information for efficient pruning and mining frequent sub-trees. Experiments results showed that OSTMiner has good response time and scales well.

基于自动机技术的XML复杂数据类型验证

复杂数据类型验证是XML文档验证的主要内容,是检查XML文档结构是否符合模式规则的关键.根据Schema规范中复杂数据类型的描述和自动机理论,提出了一种称为模式自动机的数据结构,讨论了将XML复杂数据类型结构转换成模式自动机的方法,并设计了用来验证文档结构的算法.使用模式自动机验证算法可以全面地发现XML文档中的结构错误并准确地给出相应的错误信息,在实际应用中具有很高的效率.

A UDDI Based Shared Resources Management Mechanism in Virtual Enetrprises .

Service and information resources are two kinds of major shared resources in virtual enterprises, where, service resources include third party‘s service resources and enterprise‘s legacy service resources, and information resources include database resources and file resources. Since service and information resources have distributed, autonomic, remotely bound as well as some other similar characteristics, an implementation mechanism on managing shared resources based on UDDI are presented. XML instances are used to describe resources authorization information, WSDLbased special XML instance represents information resource metadata, and these XML instancesare referenced by tModel for realizing the purpose of managing shared resources metadata based on UDDI.
