This content can be split into various categories and usually content semantically related is placed in the same area. In this paper, a software technique is presented that allows the viewers of web sites to build their own personalized portals, using specific areas of their preferred sites. This technique saves users? time and reduces the cost of browsing the web by minimizing the volume of data that has to be downloaded. It is based on an algorithm, which fragments a web page in discrete fragments using the page?s internal structure. Users utilize a web interface to define which parts of selected web pages they desire to appear in their personalized portal. No additional software needs to be installed on the users? personal computers, since this technique is designed to function centrally as a data source for a Web Server. In addition, usage of this technique reduces user perceived latency during browsing sessions, since less data must be transferred to users? personal computers. %B Journal of Network and Computer Applications, Academic Press, Vol. 30, Issue 2 %P 563 - 585 %8 April %G eng %0 Conference Paper %B 3rd International Conference on Universal Access in Human - Computer Interaction, Las Vegas, Nevada, USA %D 2005 %T A Web Clipping Service’s Information Extraction Mechanism %A Christos Bouras %A Vassilis Poulopoulos %A Ioannis Misedakis %A G Kounenis %X Information overload is one of the most important problems of today’s WWW. Users are often lost in a wealth of information when searching about a topic. Although they have specific information needs, using a search engine or regularly browsing in popular news sites for updates can lead them to search in tens or hundreds of possibly relevant pages or loose some updates that were interesting for them. One promising solution for this problem is ‘web-clipping’ services. A service like this continuously searches the Web and whenever it finds a web page that might interest some users, it informs these users that they should visit this specific page. This paper describes the information extraction mechanism of a web-clipping service that is being designed as part of a larger project for information search and manipulation. This mechanism is used to extract information from web pages and find out which links should be followed. %B 3rd International Conference on Universal Access in Human - Computer Interaction, Las Vegas, Nevada, USA %8 22 - 27 July %G eng
