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.1 aBouras, Christos1 aMisedakis, Ioannis1 aKounenis, G  uhttp://telematics.upatras.gr/telematics/publications/web-content-manipulation-technique-based-page-fragmentation?language=en01491nas a2200145   4500008004100000245006400041210006000105260001700165520094400182100002101126700002601147700002301173700001601196856013301212       2005                        eng d00aA Web Clipping Service’s Information Extraction Mechanism0 aWeb Clipping Service s Information Extraction Mechanism  c22 - 27 July3 aInformation 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.1 aBouras, Christos1 aPoulopoulos, Vassilis1 aMisedakis, Ioannis1 aKounenis, G  uhttp://telematics.upatras.gr/telematics/publications/web-clipping-service%E2%80%99s-information-extraction-mechanism?language=en
