When considering the development of the grid as the universal computing infrastructure, one of the important issues that has to be faced is porting legacy codes to the grid. In this paper an approach to wrapping cluster codes as grid services using the latest generation of grid middleware is analyzed. This approach was derived from several experiments of wrapping legacy codes. The application-d...

We report on some recent advancements on the development of the ROADRUNNER system, which is able to automatically infer a wrapper for HTML pages. One of the major drawbacks of the ROADRUNNER approach was its limited ability in handling irregularities in the source pages. To overcome this issue, we have developed a technique to deal with chunks of unstructured HTML code. Several experiments have...

Feature selection is an important technique in dealing with application problems with large number of variables and limited training samples, such as image processing, combinatorial chemistry, and microarray analysis. Commonly employed feature selection strategies can be divided into filter and wrapper. In this study, we propose an embedded two-layer feature selection approach to combining the ...

Continual advances in the manufacturing processes of integrated circuits provide designers the ability to create more complex and denser architectures and increased functionality on a single chip. The increased usage of embedded cores necessitates a core-based test strategy in which cores are also tested separately. The IEEE P1500 proposed standard for Embedded Core Test (SECT) is a standard un...

This paper presents a novel method for extracting information from collections of Web pages across different sites. Our method uses a standard wrapper induction algorithm and exploits named entity information. We introduce the idea of post-processing the extraction results for resolving ambiguous facts and improve the overall extraction performance. Postprocessing involves the exploitation of t...

This paper summarizes our approach to the Semeval 2007 shared task on “Classification of Semantic Relations between Nominals”. Our overall strategy is to develop machine-learning classifiers making use of a few easily computable and effective features, selected independently for each classifier in wrapper experiments. We train two types of classifiers for each of the seven relations: with and w...

In this paper, we propose an approach to extract information from HTML pages and to add semantic (XML) tags to them. Wrapping is an essential technique used to automatically extract information from Web sources. This paper describes both, a general approach based on rules, which can be used to automatically generate wrappers, and an assistant generator wrapper called WebMantic. We also provide ...

Components-based development is promising in improving software development productivity and software quality by re-using existing well-tested software components. However, one of the challenges of component-based development is how to integrate various components in software systems. In this paper, an approach is presented to apply design patterns to component integration. This approach uses a...
