With the development of the Internet, the World-WideWeb has become everyone’s invaluable information source. However, most of data on the Web is currently in the form of HTML pages, which is neither well-structured nor associated with schema. It is almost impossible to use such data efficiently. Web wrapper technology has been developed to transform unstructured /semi-structured data to semi-st...

Much of the world's information is stored electronically in data sources. The data sources can be full-edged databases, simple les, HTML pages or specialized data sources that possess diverse query processing capabilities. The common architecture to integrate such sources consists of mediators that give a global view over the content of all sources, and wrappers that give a local view of each s...

In a Web phishing attack, the phisher creates a forged or phishing website to deceive Web users in order to obtain their sensitive financial and personal information. Several conventiona...

Literature search and delivery in the World Wide Web becomes a rapidly expanding market. Up to now the search is mostly cost-free. But in the future we expect the appearance of more and more providers charging for their services. The main problems are finding the right provider and extracting the information. UniCats is a system for intelligent information search and extraction from multiple pr...

Current mediator and wrapper architectures do not have the flexibility to scale to multiple wrapped sources, where some sources may be redundant, and some sources may provide incomplete answers to a query. We propose a metawrapper component which is capable of handling multiple wrapped sources, in a particular domain, where the multiple sources provide related information. The metawrapper makes...

The routers are one of the critical components of Network on chip. Occurrence a failure in them causes crucial effects on communication of cores and reliability of NoC. In this paper we will propose a test wrapper for routers that testing the routers online and structurally. The proposed wrapper simulated and the results captured and showed in waveform figures.
