A wide variety of valuable textual information resides on the Web, but very little is in a machineunderstandable form such as XML. Instead, the content is usually embedded in HTML markup or other encodings designed for human consumption. The information extraction task is to automatically populate a database with content gleaned from information sources such as Web pages. Wrappers are an import...

We present a solution for the development of multiplatform and web-oriented Java applications for biometric authentication based on the BioAPI framework. Our proposal is a single Java Native Interface wrapper that is compatible with the BioAPI instantiations of Windows and Linux/Unix operating systems. Following a study of existing wrappers, we extended the open-source Linux/Unix wrapper to inc...

In this paper we propose a method to generate pausible clock based GALS wrapper circuits from the synchronous module’s Verilog specification code automatically. We first parse the input module specification and produce wrapper circuit components based on the specification of entered synchronous module. Existing methods for generation of the wrapper circuit waste the die size because they instan...

Information distributed through the Web keeps growing faster day by day, and for this reason, several techniques for extracting Web data have been suggested during last years. Often, extraction tasks are performed through so called wrappers, procedures extracting information from Web pages, e.g. implementing logic-based techniques. Many fields of application today require a strong degree of rob...

Modern database management systems are supporting the inclusion and querying of nonrelational sources within a data federation environment via wrappers. Wrapper development for Web sources, however, is a convolution of code with extraction and query planning knowledge and becomes a daunting task. We use IBM DB2 federation engine to demonstrate the challenges of incorporating Web sources into a ...

Despite numerous efforts by various developers, web service composition is still a difficult problem to tackle. Lot of progressive research has been made on the development of suitable standards. These researches help to alleviate and overcome some of the web services composition issues. However, the legacy application wrappers generate nonstandard WSDL which hinder the progress. Indeed, in add...

This work explores the usage of Linked Data for Web scale Information Extraction, with focus on the task of Wrapper Induction. We show how to effectively use Linked Data to automatically generate training material and build a self-trained Wrapper Induction method. Experiments on a publicly available dataset demonstrate that for covered domains, our method can achieve F measure of 0.85, which is...

The goal of information extraction from the Web is to provide an integrated view on heterogeneous information sources. A main problem with current wrapper/mediator approaches is that they rely on very different formalisms and tools for wrappers and mediators, thus leading to an “impedance mismatch” between the wrapper and mediator level. Additionally, most approaches currently are tailored to a...

Recent work in machine learning for information extraction has focused on two distinct sub-problems: the conventional problem of filling template slots from natural language text, and the problem of wrapper induction, learning simple extraction procedures (“wrappers”) for highly structured text such as Web pages. For suitable regular domains, existing wrapper induction algorithms can efficientl...
