| dc.description.abstract | As the internet is rapidly deployed, social media has become a part of people’s lives. The
well-known social media platforms, like Facebook and YouTube, make people search for
information from the server and publish their idea via the server. Such internet service is the
so-called social web or Web 2.0. Daily life has been changing by the internet, but new problems
emerge, one of which is big data companies benefit from personal information, but internet
information providers do not realize that they shall have ownership.
The development and discussion about internet information ownership have become an
important part of Web 3.0. To decrease the monopoly of centralization, decentralized network
technologies have received much attention. Nevertheless, the client-server-based service model
is still the major service model on the internet. How to smoothly transform the service model
from client-server to user-centric is ongoing. Various contemporary and distributed services
and applications have been proposed and developed in recent years.
This study aims to propose a new service model which is able to decrease the degree of
information centralization, lower the development cost and seamlessly transfer. Under the
traditional client-server service model, users often utilize the browser to connect to a designated
web server and input the keywords for searching the information he/she is interested in. This
study proposes to utilize the object management group (OMG) data distribution service (DDS)
technology in order not to change the familiar browser of users, but users can retrieve much
more information from all information providers via the publish/subscribe ability of the DDS
agent which is developed in this work. Specifically, the user still uses a browser to input
keywords, and the developed DDS agent will play the role of publisher to publish the keywords
on a specific topic. Then, those well-known search engines, such as Google, Bing, Baidu, etc.,
will play the role of subscribers to receive the keywords by means of a subscription of the topic.
iv
After then, each search engine will reply its search result to the DDS agent independently via
the same Pub/Sub model. Upon the DDS agent collects the corresponding replies, it returns the
re-organized web page to the user’s browser for rendering. From the user’s point of view, the
user obtains all of the results from those subscriptions after it uploads a keyword once.
As the majority of users and information providers participate in the proposed DDS-based
service model, users can easily and fast access information. Eventually, the network service
model is transformed from a network-centric client-server model to a user-centric peer-2-peer
model, and the monopoly of centralization in the past decades is resolved as desired. | en_US |
