The explosive growth and popularity of the World Wide Web has resulted in a huge number of information sources on the Internet. However, due to the heterogeneity and the lack of structure of Web information sources, access to this huge collection of information has been limited to browsing and keyword searching. Sophisticated Webmining applications, such as comparison shopping, require expensiv...

As our reliance on computers increases, so does the need for robust software. Previous studies have shown that many C libraries exhibit robustness problems due to exceptional inputs. This paper describes the HEALERS system that uses an automated approach to increasing the robustness of C libraries without source code access. The system extracts the C type information for a shared library using ...

To enable accessing deep web information at semantic level, this paper develops a semantic query rewriting and planning mechanism on heterogeneous database enabled web information system with complex ontology mapping technology. It discusses the procedure of converting database schema and instances to ontologies at first, and then the patterns of complex ontology mappings , and then the ontolog...

We present a general framework for information extraction from web pages based on a special wrapper language, called token-templates. By using token-templates in conjunction with logic programs we are able to reason about web page contents, search and collect facts and derive new facts from various web pages. We give a formal definition for the semantics of logic programs extended by token-temp...

THE CURRENT TREND of SoC design has made conventional test methodologies increasingly difficult. Performing brute-force test pattern generation (ATPG) on the entire SoC is often infeasible, because the design can exceed the test pattern generator’s capabilities. At other times, some black-box third-party cores within the SoC might have their own test patterns generated at the core boundary. IEE...

Many process industry subsystems were developed separately. They didn’t collaborate efficiently, which makes it difficult for information integration. In this paper, a web service based framework is presented to address this problem, in which every process industry subsystem is described as a web service by web service wrapper and registered in the UDDI register centre, according to different i...

In this report we compare the papers [AKM + 03] and [ETL03]. We show that the two proposed systems realize different goals with the same or similar underlying technics. • Source data of interest [ETL03] takes web pages containing HTML tables of interest for a given application domain as the input whereas [AKM + 03] considers unstructured text from webpages for the knowledge extraction process. ...

We present the architecture and implementation of an interactive system for monitoring long-running jobs on large computational clusters. JobMon comprises an asynchronous intra-cluster communication server and a Clarens web service on a head node, coupled with a job wrapper for each monitored job to provide monitoring information both periodically and upon request. The Clarens web service provi...

The transition from existing World Wide Web content to the Semantic Web relies on the labeling and classification of existing information before it is useful to end-users and their agents. This paper presents a wrapper induction system designed to allow end-users to create, modify, and utilize semantic patterns on unlabeled World Wide Web documents. These patterns allow users to overlay documen...
