The testing time for a system-on-chip (SOC) is determined to a large extent by the design of test wrappers and the test access mechanism (TAM). Wrapper/TAM co-optimization is therefore necessary for minimizing SOC testing time. We recently proposed an exact technique for co-optimization based on a combination of integer linear programming (ILP) and exhaustive enumeration. However, this approach...

The wrapper feature selection approach is useful in identifying informative feature subsets from high-dimensional datasets. Typically, an inductive algorithm “wrapped” in a search algorithm is used to evaluate the merit of the selected features. However, significant bias may be introduced when dealing with highly imbalanced dataset. That is, the selected features may favour one class while bein...

We introduce an innovative approach to wrapping semi-structured web pages in order to generate structured data. Unlike other work in this area based on physically specifying the location of information, our approach is based on human design psychology that captures more stable features across web pages, which we believe renders a more robust result in coping with changes in the web pages. In th...

The worker/wrapper transformation is a general technique for improving the performance of recursive programs by changing their types. The previous formalisation (Gill & Hutton, 2009) was based upon a simple fixed point semantics of recursion. In this article we develop a more structured approach, based upon initial algebra semantics. In particular, we show how the worker/wrapper transformation ...

There exist two types of wrappers: the string based wrapper such as the LR wrapper, and the tree based wrapper. A tree based wrapper designates extraction regions by nodes on the trees of semistructured documents. The tree based wrapper seems to be more powerful than the string based one. There exist, however, many HTML documents on the Web such that a standard tree based wrapper fails to extra...

The amount of useful semi-structured data on the web continues to grow at a stunning pace. Often interesting web data are not in database systems but in HTML pages, XML pages, or text les. Data in these formats is not directly usable by standard SQL-like query processing engines that support sophisticated querying and reporting beyond keyword-based retrieval. Hence, the web users or application...

In this paper, we focus on the problem in information integration system of obtaining data from heterogeneous data source accurately and effectively. XML is used as data exchange format of the wrapper. We design the wrapper architecture based on the conversion and management of the views as the bridge from global schema to local schema of various data sources. Our wrapper has two main subsystem...

Wrapper is a traditional method to extract useful information from Web pages. Most previous works rely on the similarity between HTML tag trees and induced template-dependent wrappers. When hundreds of information sources need to be extracted in a specific domain like news, it is costly to generate and maintain the wrappers. In this paper, we propose a novel templateindependent news extraction ...

In this paper, we present a generic wrapper that enables the optimization of legacy codes assembled in application workflows on grid infrastructures. We first describe advantages of a service-based approach for job management. We then introduce our wrapper, that works at execution time, thus allowing service grouping strategies to optimize the execution. We demonstrate performance results on a ...
