A Semantic Web Based Scientific News Aggregator




ABSTRACT


Scientists want to stay connected with everything that is new in scientific world, so they
constantly read

several online scientific magazines and
newspapers. However, not all the
subjects are of interest to everyone.

Consequently, a user is forced to do a lot of browsing to find
the articles which are important to him. This paper presents a scientific news aggregator,
structured as an online magazin
e. The content is automatically withdrawn from several online
publications, available on the Internet.
A
ll the information about the items posted on the site is
stored in a
database,
which is automatically updated.


EXISTING SYSTEM


The existing system has

many shortcomings associated with it.

The Web is now a huge, dynamic
and interactive platform, providing millions of users the chance to collaborate and to exchange
information. The number of users, the number of sites and the amount of information availa
ble
on the Internet has grown drastically and things are becoming more and more difficult to
manage.

Scientists are very difficult to update the day to day news.

Nowadays, we seem to be
overwhelmed with information: on TV, at the radio, but mostly on the I
nternet. Sometimes, the
user needs to do a lot of searching and browsing in order to find what he is looking for. In this
context, the idea of news aggregators becomes more and more popular.


PROPOSED SYSTEM


This paper presents a scientific news
aggregator,

structured as an online magazine.

The content is

automatically withdrawn from several online publications, available on the Internet. We called
our site

Science NEWS”. Although for the moment, the site is dedicated to a public who is
intereste
d in the scientific subjects, it can be easily extended or adapted to other preferences. The
application is implemented in J2EE and uses a knowledge database built on the concept of
Semantic Web. The idea of a news aggregator is not new. A news aggregator
is a software
application, which periodically

reads several news sources and displays them on a separate page.

The “Science NEWS” site is divided into 6 main categories of articles: Time & Space, Mind &
Brain, Plants & Animals, Computers & Math and Earth &

Climate. They are accessible from the
main page.However, the number and type of categories can be modified. They are stored in the
knowledge database, so they can be added and updated. The main page contains a selection of
News.
