This paper presents a new feature selection (FS) algorithm based on the wrapper approach using neural networks (NNs). The vital aspect of this algorithm is the automatic determination of NN architectures during the FS process. Our algorithm uses a constructive approach involving correlation information in selecting features and determining NN architectures. We call this algorithm as constructiv...

Semi-automatic wrapper generation tools aim to ease the task of building structured views over web sources. But the wrapper generation techniques presented up to date show several weaknesses when dealing with the complex commercial web sources of today, specially when constructing advanced navigational sequences for accessing data. We present Wargo, a semi-automatic wrapper generation tool, whi...

The proliferation of online information sources has accentuated the need for tools that automatically validate and recognize data. We present an efficient algorithm that learns structural information about data from positive examples alone. We describe two Web wrapper maintenance applications that employ this algorithm. The first application detects when a wrapper is not extracting correct data...

The premise, upon which I evaluate the TCP-friendliness of VOIP traffic, is content and the necessary justification. In the reminder of this paper I will give a description of the paper as well as the assumptions and claims of the authors. Also I will give my own personal conclusions about the authors’ work along with sufficient justifications.

Extracting information from tables is essential for Internet information extraction. However, most web tables are designed in HTML format. To decipher their semantic meanings a system needs to deal with various layouts, which is quite cumbersome. Previous works have two major approaches: layout enumeration approach and wrapper approach. The first approach is to match the table with presorted la...

There are multiple scenarios where at-speed coverage over core boundaries is difficult. The idea is to resolve this problem using two stage wrapper. Generally single stage wrapper is used in the present design techniques, and is used in industries. Here two stage wrapper is used in which test coverage has been increased. Additional scan compression architecture is introduced to reduce the patte...

In this paper we demonstrate how to formalize UML-based development of protective wrappers for tolerating transient faults. In particular, we focus on the fault tolerance mechanisms common in the avionics domain and show the development of a protective wrapper, called Failure Management System. We demonstrate how to integrate the formal refinement approach proposed earlier into the UML-based de...
