The internet has become an attractive avenue for global e-business, e-learning, knowledge sharing, etc. Due to continuous increase in the volume of web content, it is not practically possible for a user to extract information by browsing and integrating data from a huge amount of web sources retrieved by the existing search engines. The semantic web technology enables advancement in information...

Next Generation Network envisions convergence of different wireless networks to provide ubiquitous communication environment to the mobile user. The ubiquity is achieved by enabling a mobile user to switch to a network with better QoS (Quality of Service), by a mechanism called vertical handoff. We propose a vertical handoff management architecture which handles TCP adaptation and ensure effici...

This vignette demonstrates the use of simPopulation for simulating population data in an application to the EU-SILC example data from the package. It presents a wrapper function tailored specifically towards EU-SILC data for convenience and ease of use, as well as detailed instructions for performing each of the four involved data generation steps separately. In addition, the generation of diag...

My research field is highly diverse. It interweaves many different areas in information technology and bioinformatics. The system I propose to implement can automatically locate, understand, and extract online biological data independent of the source and also make it available for Semantic web agents. This research field requires background knowledge from (1) Information Extraction, (2) Schema...

In this paper we describe IRS-II (Internet Reasoning Service) a framework and implemented infrastructure, whose main goal is to support the publication, location, composition and execution of heterogeneous web services, augmented with semantic descriptions of their functionalities. IRS-II has three main classes of features which distinguish it from other work on semantic web services. Firstly, ...

Because much of the information on the web is presented in some sort of regular, repeated format, “understanding” web pages often requires recognizing and using structure, where structure is typically defined by hyperlinks between pages and HTML formatting commands within a page. We survey some of the ways in which structure within a web page can be used to help machines understand pages. Speci...

Web data analysis applications such as extracting mutual funds information from a website, daily extracting opening and closing price of stock from a web page involves web data extraction. Every time you need analyze data, you need to visit number of web sites. It is very time consuming process to construct wrapper to visit those sites and collect data. In this paper, we propose technique calle...

Template-generated Web pages contain most of structured data on the Web. Clustering these pages according to their template structure is an important problem in wrapper-based structured data extraction systems. These systems extract structured data using wrappers that must be matched to only particular template pages. Selecting single type of template from all crawled Web pages is a time consum...

We study the core fragment of the Elog wrapping language used in the Lixto system (a visual wrapper generator) and formally compare Elog to other wrapping languages proposed in the literature.
