Abstract
Accessibility of information on the web is the main feature of knowledge acquisition .
Currently, the knowledge is facing several problems relating to integration of sharing
information and systems, also representation across heterogeneous organizations. The e-
government is the civil and political conduct of the government, which involves use
information and communication technologies (K’T). E-government encounters big
challenges in achieving interoperability and integration differences in laws, regulations,
services, administrative processes , along with the different languages spoken across
different regions and countries .
There are numerous approaches. proposals. frameworks- and projects available to
achieve semantic interoperability in the e-Government domain; especially dealing with the
creation and management of semantic web services. There is a lack of supporting
methodology, specialized tools, and guidelines which describe how much formal semantic
description of these services in practical applications can be create and maintained.
Moreover, in the e-Government paradigm, it is expected to have formatted information
available in different means, and can easily presented to senior citizens, government
officials, and others.
Therefore, the e-government services need to provide information with format and
methods of delivery in convenience with the users requirements and the alerted situations,
that can facilitate end-user access to Public Administration (P A) services. This can be
established by assembling service for browsing, discovery, and execution easier and more
effective.
Integrating information system in any domain for E-government is facing several
difficulties, such as structural and semantic sharing in similar information for applications
and services, in addition, representation across heterogeneous organizations. In this respect,
the semantic web plays a dynamic role in knowledge sharing and managing. Semantic
Web technologies based on ontology have brought about promising solutions to the
semantic integration information difficulties. While ontology is an explicit specification of
conceptualization , it has defines the terms with specified relationships between the
concepts, and interpret by both humans and computers software.
