The field of e-government has always been a distinct area of standard testing for software research. To expound further, the e-government field presents a variety of principled elements, which makes the system more challenging and further encouraging than other electronic scenarios (e.g., e-business and e-commerce).
To a certain extent, selecting an appropriate Web modelling technique (e.g., ontology) illustrates the critical role of establishing a successful e-government system. Ontology has been used in e-government to describe and define services provided to citizens. In addition, ontology technology is expected to play a pivotal role in enabling semantic web services.
While creating the ontology for e-government remains a significant task concerning its planning and implementation, there are still a few investigations to deal with the ontology technology’s effect on the government’s capability to deliver its due services.

Because of the noticeable failure in large parts of e-government projects, the current study stands out as an attempt to improve their performance in terms of service delivery, appropriateness of applying modern technologies, and finally, a research-driven application. Factors for conducting academic research will lead to refining knowledge-building related to design procedures and setting up the ontological framework within the e-government domain.

This research aims to verify whether the ontology technology can be described and considered a reference technology for providing e-government services over the Internet. Consequently, the research presents a practical method established on experimental research that moves nearer to the fact of the true function of ontological procedure in the field of e-government.
In this study, the educational system in Singapore is used to represent the domain of egovernment in which research questions are raised and addressed; also, general impressions can be tested and originated.
The research methodology utilised in the research has the advantage of being consistent in the case study. Inside the case study, both quantitative and qualitative methods are applied to collect data and gain access to an answer to the research question.

Concerning the establishment of ontology for the Singapore education system (OSE), which creates the educational system in Singapore, an implementation of Methontology seems to be an extremely suitable methodology for applying ontology for the Singapore education system (OSE) structure in this research. Methonlogy defines a comprehensive ontology development methodology. Moreover, the separate actions for ontology structure achieved the problem in seven stages.

The ontology evaluation of Singapore’s education system (OSE) will be based on the ontology assessment process implemented by Gómez-Pérez’s approach, which comprises the binary essentials: specifically, verification and validation of the (OSE) system. However, the criteria for the evaluation concerned with delivering services to perform efficiently, performance, and easy access of services in e-government; more specifically, system recall, semantic search, data/service integration, response time, and natural language interface. Ontology (OSE) is reviewed by experts in the field where experts fill values assessment in a survey which consists of several questions related to these criteria.
Although the domain experts have the knowledge and were able to evaluate ontology in various concentrations, for example, philological, language, concept, and data to ensure that the expected ontology conducted components are established.

The research study is involved in and tailored for the following contributions:

- Creating an ontology model for the Singapore education system (OSE) environment to integrate e-government with design science.
- The educational system model is a practical foundation for building the egovernment framework, as the study relies on the ontology analysis of the educational model in the e-government framework.
- Identify the priority of services.
- Design the Ontology for Singapore Education system Website (OSEW).
- Adapting Methontology that appears to be an extremely suitable methodology for applying ontology for the Singapore education system (OSE) structure in this research.
- Evaluation and testing of the (OSE) system.

The study's findings found that the ontological technique can be employed to reach a successful electronic system.
The OSE ontology indicates the fulfilment quantities of specialists, including OSE ontology. The system showed a high rate of acceptance and satisfaction in the four layers of the evaluation represented in clarity\ vocabulary and lexical, structural, representational, and semantic, and data \ application layers.
