Power consumed by the memory system becomes a serious issue as the size of installed memory increases. With various low power modes that can be applied to each memory unit, the operating system can reduce the number of active memory units by collocating active pages onto a few memory units. This paper presents a memory management scheme based on this observation, which differs from other approa...

Mobile platforms are becoming an increasingly important alternative for accessing web pages. Many Web pages are not suited to these platforms and need to be adapted, or rewritten from scratch. Adaptation can be made in two ways: either by a dynamic conversion or by a static reengineering. VAQUITA belongs to the second category by applying a model-based approach to reverse engineer web pages at ...

In this demo we present RDFauthor, an approach for authoring information that adheres to the RDF data model. RDFauthor completely hides syntax as well as RDF and ontology data model difficulties from end users and allows to edit information on arbitrary RDFaannotated web pages. RDFauthor is based on extracting RDF triples from RDFa-annoted Web pages and transforming the RDFa-annotated HTML view...

The Web is a context in which traditional Information Retrieval methods are challenged. Given the volume of the Web and its speed of change, the coverage of modern web search engines is relatively small. Search engines attempt to crawl the web exhaustively with crawler for new pages, and to keep track of changes made to pages visited earlier. The centralized design of crawlers introduces limita...

This article presents WebAnnotator, a new tool for annotating Web pages. WebAnnotator is implemented as a Firefox extension, allowing annotation of both offline and inline pages. The HTML rendering fully preserved and all annotations consist in new HTML spans with specific styles. WebAnnotator provides an easy and general-purpose framework and is made available under CeCILL free license (close ...

World Wide Web is growing at a very fast pace and makes a lot of information available to the public. Search engines used conventional methods to retrieve information on the Web; however, the search results of these engines are still able to be refined and their accuracy is not high enough. One of the methods for web mining is evolutionary algorithms which search according to the user interests...

In this paper we describe a method for the expansion of training sets made by XY trees representing page layout. This approach is appropriate when dealing with page classification based on MXY tree page representations. The basic idea is the use of tree grammars to model the variations in the tree which are caused by segmentation algorithms. A set of general grammatical rules are defined and us...

As so far, most of the information on the internet are designed for computer display, which can achieve the desired effect at 800*600 or higher resolution, but the normal TV’s resolution is much lower, so the web page looks abnormally on TV. Furthermore, it also can’t be browsed by phone and PDAs as PC does. Based on the analysis of the display principles of TV and computer, a new method which ...

Seas of web pages in the Internet contain free texts in natural language that are only read by human beings. To be understandable for machines, these pages should be annotated with semantic markups. Manually annotating large amounts of pages is an arduous work. This has made automatic semantic annotation an urgent challenge. In this paper, we propose a machine-learning based automatic annotatio...
