Nigeria has 169 universities approved by National University Commission (NUC) with 43 Federal Universities, 47 State Universities and 79 Private Universities. The universities are located in different geographical areas and collaboration among these universities is difficult and this makes accessibility to data and information resource of the universities a problem. As a result quite a number of knowledge built from these resources are locally managed within each university private network that is not shared with other universities due to lack of virtual collaboration on a grid computing platform. Knowledge building and management in a country is a function of the information that one could have access to with ease but non-collaboration of the universities in a virtual environment is a hindrance to quality national knowledge building and management. Thus the need arises to embrace grid system as platform for all universities to pool their resources together and hence make their information resources available and accessible for knowledge building and management. This report presents an overview of Nigeria universities’ operations as regard their research and innovation policies and vis-à-vis governance and resource management across public and private universities. Also we did a systematic review and analysis of knowledge grid (KG) technology vis-à-vis its use for knowledge management in Nigerian universities. We focused on identifying the strengths and challenges of knowledge grid development and implementation vis-à-vis the technological, economic and social implications involved in the process. Our future work is to develop a robust knowledge grid model that will allow collaboration among universities in Nigerian community and hence facilitates information and knowledge sharing and management among the universities.
In a knowledge based economy, universities are instrument for change and growth of the nation. According to National Policy on Education (2012) in Nigeria, university is responsible for developing people with skills and knowledge needed for economic development of a nation (Musa & Ibrahim, 2017). Studies were done by many authors to show the importance of skills acquisition and entrepreneurship development among university students. The vocational training allows students to acquire relevant knowledge, practical skills and empower them economically and aid industrialisation (Akuegwu, 2016; Baderinwa-Adejumo & Akrai, 2017; Esomonu, Esomonu, & Oluwatoyo, 2016; Ezeonwurie, 2017; Medugu, Abdulkarim, & Bashir, 2017). Moreover empirical studies were done to see the effect of technological tools on knowledge management (KM) which bring about effective instructional delivery of knowledge via mobile communication technology (Onwusuru, Uka, & Udeze, 2013), electronic learning (Ibezim, 2013; Oleabhiele, 2015), and grid and cloud computing (Abba & Bakon, 2016; Etim, Erema, & Ekpo, 2016; S. Misra & Adewumi, 2015; Nsofor, Bello, Umeh, & Oboh, 2015). Thus the use of Information and Communication Technology (ICT) is a key factor to achieving effective and efficient teaching and learning in institutions.
Furthermore, management of organisations is based on knowledge and it has become the most important resource more than land, labour, capital etc. (Owoc & Marciniak, 2013; Sanchez, 2001; Wang & Ji, 2005). Knowledge management entails the following functions (Brewster, Ciravegna, & Wilks, 2002; Marwick, 2001; McQueen, 1998; Uren et al., 2006; Zins, 2007): information classification for proper understanding; sharing of ideas; promotion of collaboration among organizations; and standardization of information vis-à-vis easy retrieval. The works of scholars from a multitude of disciplines have suggested that access to a rich diversity of information encourages organisation existence and maintain growth (Owoc & Weichbroth, 2015; Wang & Ji, 2005).
Several techniques have been used in tertiary institutions of learning outside Nigeria to meet up with the challenges and vis-a-vis promotes knowledge-driven economy to ensure good quality, efficiency and ultimately leverage on competitive edge. Examples are: Mauritius (Abbass, 2017), Iran (Yokhaneha & Baghoumian, 2014), Europe (Owoc & Weichbroth, 2015), Asia (Wang & Ji, 2005), Kenya (Murumba & Micheni, 2017), etc. Many studies have also proven that modern knowledge sharing and management system such as knowledge grid (KG) is more effective than traditional ways of sharing and managing knowledge (Sani, 2015; Yokhaneha & Baghoumian, 2014). Thus Knowledge Grid (KG) is an intelligent grid system that provides a sustainable interconnected platform whereby people and relevant digital devices can effectively capture, publish, share and manage knowledge resources (Ohiorenoya & Eboreime, 2014). Knowledge grid (KG) can be employed as a tool for collaboration, access and sharing of individual knowledge among Nigerian universities and hence enhancing research works and other benefits.
According to (Ohiorenoya & Eboreime, 2014), the implementation of KG is still low in Nigerian universities. Collaboration among these universities is difficult and this makes accessibility to information resource of the universities a problem (Ohiorenoya & Eboreime, 2014). As a result quite a number of knowledge built from these resource are locally managed within each university private network that is not shared with other universities due to lack of collaboration (Ohiorenoya & Eboreime, 2014). This work aimed at giving a report on the strengths and weaknesses of the use of Grid system in Nigerian universities. An overview of the operations of the Nigeria universities was reported in this research. Moreover, the technological, economic and social implications of implementing KG in Nigerian universities were presented.
The paper is organised as follows: Section 2 present a contextualized overview of the Nigerian Universities. Section 3 presents the literature review; Section 4 presents strength, challenges and implications of knowledge grid system for knowledge sharing in Nigerian universities. Conclusion and future research are presented in Section 5.
There are 169 universities approved by National University Commission in Nigeria (NUC). There are 43 Federal universities; 47 State owned universities = 43; and 79 Private universities. The universities are located in different geographical areas (www.nuc.edu.ng). In addition the universities are classified as follows: (1) Conventional universities – these universities run degree programmes in almost all disciplines; (2) Universities of Technology – these are specialized universities that run technology based degree programmes only; (3) Universities of science and Technology – these are also specialized universities that run only science and engineering based degree programmes; (4) University of Medical sciences – there is one University of Medical Sciences in Nigeria. It is also a specialized university that runs only medical oriented degree programmes; (5) Technical University – there is one Technical University in Nigeria. It is a specialized university that runs only Science and Engineering oriented degree programmes and emphasis is on hands-on training and entrepreneurship.
Research is the process of creating new knowledge or new insights on knowledge, or unlocking knowledge. Innovation is the generation, acceptance and implementation of new ideas, processes, methods and changes. The goal of National ICT Policy is to facilitate the transformation of Nigeria into a knowledge-based economy and becoming a top 20 economy by the year 2020 (National Information and Communication Technology (ICT) Policy, June 2012). National Information Communication Technology (ICT) Policy (2012), Science Technology and Innovation (STI) Policy (2011) (Nigeria, 2011), and other related policies have placed importance on research as an vital part of national developmental planning. The policy documents recognized the noteworthy contribution that the university education could make in this respect, both as warehouses of knowledge and as the nation’s leading research centres in collaboration with the research institutes.
Nigerian universities undertake more research than other institutions of learning such as Monotechnic, Polytechnic, College of Education etc. Though in conventional universities, their research works tend to be more academic than applied research. In the university, several academia have published their research works in journals and other scholarly publication outlets. Most of these research publications are for career progression and intellectual stature of the researchers. Moreover research outputs reside in individual computers or private servers or university server which are not interconnected for the purpose of information sharing. In addition many of the institutions are lagging behind in the area of research and innovation and are also unaware of the research data, outputs and other research materials available in each University. The need to encourage collaboration among researchers and universities led National University Commission (NUC) in Nigeria to propose the frameworks for the following computing systems: Nigeria University System Management Portal (NUSMAP) that acts primarily as a data collection portal from all the universities and Online Programme Accreditation Portal to automate accreditation process of universities (http://pubs.sciepub.com/ajse/2/2/3/index.html). None of these frameworks support collaboration, information and knowledge management among the Nigerian universities. Thus it is essential in the current time to have a grid system that is knowledge driven and hence help to facilitate data collection, data standardization and data and information sharing among researchers and the universities. In a study by (Yusuf, 2012), poor motivation, poor and irregular funding, obsolete research infrastructure, inadequacy of qualified research personnel, general lack of research focus and poor linkage between researchers and the industrial sector are factors that hinders Nigeria universities researches. These constraints affect the research capacity and thus the national development.
In Nigeria, there are government agencies responsible to manage research funds provided by the Federal and State government: National Science and Technology Fund (NSTF); Education Trust Fund (ETF) and Tertiary Education Trust Fund (TETFUND); NUC etc. Aside the aforementioned agencies, private companies and agencies also fund research works in the Universities. In addition, research projects are also occasionally funded by international and philanthropic organisations such as World Health Organization (WHO), United Nations Children’s Fund (UNICEF), Bill and Melinda Gates Foundation, Ford Foundation etc.
Research in the universities may take any of the following forms (i) individual research which is initiated and conducted by researcher(s) and who seek funding from internal or external funding agencies; (ii) Institutional research which is initiated and supervised by the institution(s), or faculty or department and the funding is internal; (iii) Contractual research by external bodies either government, private sector, Non-Governmental Organization etc, they fund the research and have the right of ownership; (iv) Collaborative research which is a joint research with same goals and involving sharing of ideas, facilities between researcher(s), institution(s), organization(s), countries or regions; and (v) Student research that can be an undergraduate or postgraduate student project, supervised by the student’s department and the result is reported in student’s thesis or dissertation and it is self-funded in most cases (Yusuf, 2012).
In Nigeria, the public universities are the Federal and State universities owned and funded by Federal and State government respectively and the private universities are owned and funded by individual, private organization, and religious organizations. National University Commission (NUC) is the government regulatory agency that oversees the proper running, approval and accreditation of academic programmes in Nigerian universities.
Governance and resource management in the Universities are autonomously done by the University internal management with the Vice Chancellor as the Chief Executive Officer. Other members of the university internal management are as follows: University Registrar, Bursar, Librarian, Deans, Directors and Heads of Departments. The internal management oversees the daily running of the university services. Other members of the University management that are external and make strategic decisions about the universities and also regulate the operations of the internal management are the: (i) Visitor, which is the Nigerian President in the case of Federal Universities and the State Governor in the case of State owned Universities; (ii) Chancellor which is appointed by the President for Federal Universities and State Governors for State Universities; (iii) Governing Council which is constituted by the President for Federal Universities and State Governor for State Universities.
There are many policies in Nigeria, among which are Information Policy, National Science and Technology policy (National Information and Communication Technology (ICT) Policy, June 2012; Yusufu, 2007) etc. Information policy is the rule, regulation, or practice that affects the conception, acquirement, organization, distribution, and evaluation of information (Yusufu, 2007). The goal of any policy is to circumvent some negative effect that has been noticed in the organization. The policies have affected positively the following associations, ministries and government parastatals: Librarians/Information Scientist, Nigeria Computer Society, Mass Media Practitioners, Ministry of Science and Technology, Ministry of Information, Youth and Culture etc. National Science and Technology Information Policy was established as one of the avenue for distribution of usable research findings to industrialists (UNO, 2011).
In 1988, the National Documentation and Information Centre for Science and Technology (NADICEST) was established to promoting information activities amongst higher institutions of learning in Nigeria (Ogunrombi, 1997; Yusufu, 2007). In 1990, Management Information System (MIS) policy was presented to Nigerian universities under the regulation of the National Universities Commission (NUC) (Bretschneider, 1990; Yusufu, 2007). The goal is to make use of information technology in the teaching and research activities of the universities. The impact of this today has brought about computerization in the processing of information and endowment of information services in Nigerian universities (Yusufu, 2007).
International agencies such as WHO (Dim & Onah, 2007), United Nations Educational, Scientific and Cultural Organization (UNESCO) (Meek, Teichler, & Kearney, 2009; Kearney, 2009; Meek & Teichler, 2009; UNESCO, 2009), European Commission (Commission, 2014), United States Agency for International Development (USAID) (USAID, 2015–2020), Ford Foundation (Oranu, 1977; Osemeobo, 2001; Smock & Smock, 1969), World Bank (Babalola, Sikwibele, & Suleiman, 2000; Banya & Elu, 2001) are involved in the activities of Nigerian universities. They support in funding of research, training, curriculum development and provision of technology driven teaching aids.
World Health Organization (WHO) had commission some health research projects for national development in Nigeria (Dim & Onah, 2007; Ike, 2008). European commission carried out many projects in Nigeria community (Commission, 2014). USAID supported education in accordance with National Policy on Education, the quality of and access to education improved equitability and sustainably in Northern part of Nigeria (USAID, 2015–2020). The Research and Development Centre of the University of Agriculture, Abeokuta, Nigeria is one of the projects done by UNESCO (Meek, Teichler, & Kearney, 2009; Kearney, 2009; Meek & Teichler, 2009; UNESCO, 2009). In 2005, the need to carry out reform was completed and implemented under the Nigeria/UNESCO Science, Technology and Innovation (STI) reform initiative (UNO, 2011; UNESCO, 2005). Ever since 2001, the UNESCO Forum has pursued its obligation to help understand, build and maintain knowledge systems through research, as basis for scientific innovation at national, regional and international levels (Meek, Teichler, & Kearney, 2009; Kearney, 2009; Meek & Teichler, 2009; UNESCO, 2009).
In recent times World Bank has selected 16 universities in Nigeria as African Centers of Excellence (NAN, 2018; Wahab, 2018). This is to support the recipients to promote regional specialization among participating universities in areas that address regional challenges and strengthening the capacities of these universities to deliver quality training and applied research. The following Nigerian Universities/institutions are recipients of this award: Lagos State University; Centre for Oilfield Chemicals Research (CEFOR); University of Port-Harcourt; ACE for Genomics of Infectious Diseases, Redeemer’s University; and ACE on Neglected Tropical Diseases and Forensic Biotechnology, Ahmadu Bello University etc.
Systematic Literature Review (SLR) (Keele, 2007; Khan, Niazi, & Ahmad, 2008) was carried out in this study and the search strategy adopted to get required literatures for this research was composed as follows: (a) Constructed search terms by identifying major keywords, required action and expected results; (b) Determined the synonyms or alternate words for the major keywords; (c) Established exclusion criteria to make exclusion in the course of search and (d) Applied Boolean operators to construct the required search term. Stated below are the results for each stage of the search strategy:
|Result for (a):||Nigeria, Tertiary, Institution, Management|
|Result for (b):||Knowledge, Grid, “knowledge sharing”|
|Result for (c):||library, blood, HIV, AIDS, Autism, Breast, Cancer, Aquaculture, Hospital, Water, Solar, Manufacturing, Vegetable, Human, Resource, Audit, Drug, Law, Bird, Property|
|Result for (d):||Nigeria Tertiary institution management Knowledge OR Grid OR “knowledge sharing” -library -blood -HIV -AIDS -Autism -Breast -Cancer -aquaculture -hospital -water -Solar -Manufacturing -Vegetable -Human -Resource -Audit -drug -law -bird -property|
The major search terms required to guide our literature search on Google scholar search engine are listed in results for (a) and (b) above. Our aim is to identify all the research works on knowledge management and application of grid technology in knowledge sharing. Our domain of concern is tertiary institutions in Nigeria and abroad. Lots of articles were listed based on the search terms stated in result for (a) and (b) above and many of the articles have no relevance to our research and therefore we excluded the irrelevant articles using the exclusion terms as listed in result for (c). The result for (d) gives the complete search string that we used for our literature search on Google scholar having all the included and excluded terms and terms that are synonyms. Logical operator “OR” helps to combine terms that are synonyms while the negation operator “-” preceding the excluded terms indicates that all articles focusing on such terms must be excluded from the search results.
In this research, selection was from peer-reviewed articles on Google scholar database and we accessed strictly articles gotten using the search term constructed. Resources checked are: conference proceedings, specific journals, book chapter and books. Systematically we reviewed studies on knowledge management using knowledge grid. Studies that met a priori defined inclusion and exclusion criteria were considered for review. Manuscripts that were comments, letters, and editorials were excluded. Studies were properly categorized.
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) (Moher, Liberati, Tetzlaff, & Altman, 2009) was adopted to detail the study selection process that established the studies included and those excluded for this research. Studies were properly categorized. Figure 1 presents the study selection process in PRISMA flow diagram.
Knowledge is a valuable resource and the key factor for any successful organisation and it should be properly managed; thus knowledge is power. Therefore KM is the process used to manage human intellectual assets; hence safeguard and propagate knowledge owned by individuals via a shared resource for people to have access to it. Knowledge Management (KM) process in organizations contains knowledge acquisition, creation, refinement, storage, sharing, and application with the view to ensuring better knowledge practices, enhanced organizational behaviours, better decisions and enhanced organizational performance (King, 2009). Knowledge Management is the act that enhances the growth of organisation and allows innovation and global competitiveness (Nickols 2000).
Universities are structured to be citadel of knowledge. That is academic institutions responsible to make correct knowledge from available and reliable knowledge sources and share with authorized users at the right time. Thus there are relevant mechanisms and technologies (such as Knowledge Grid, Courseware management system etc) that are put in place to facilitate knowledge acquisition, creation, refinement, storage and sharing with the view to ensure adequate scientific research, technological innovation, collaboration and cooperative teamwork. We focused on KG in this paper as an intelligent tool for knowledge management in Nigerian universities.
Knowledge Grid is an intelligent technology for sustainable interconnection of people and computers used to effectively capture, publish, share and manage knowledge resources in the grid of several computer networks of different organizations. It focuses on providing data, services and knowledge resources in a standardized format and hence give well-defined meaning that are understandable at both the machine and human levels (Zhuge and Li, 2004, Zhuge, 2008). According to (Zhuge, 2008): “The knowledge grid environment consists of autonomous individuals, self-organized semantic communities, an adaptive networking mechanism, an evolving semantic overlay keeping meaningful connection between individuals, flows for dynamic resource sharing, and mechanisms supporting effective resource management and providing appropriate knowledge services for problem-solving and innovation. It supports innovation and harmonious development of science, technology and culture”. Knowledge Grid is built on the use of high-bandwidth communication networks and high-performance parallel computers for the purpose of mining data (Foster, 2003; Foster & Kesselman, 1999; Foster & Kesselman, 2004; Foster, Kesselman, & Tuecke, 2001; Zaki, 2000). It is premised on computational grid that provides reliable and ubiquitous access to high-end computational resources. KG has been implemented as Parallel and Distributed Knowledge Discovery (PDKD) applications in geographically distributed environment. The KG architecture is built on top of grid toolkits and services and therefore uses basic grid services to construct precise knowledge mining services (Cannataro, Talia, & Trunfio, 2001). The KG services are organized in two hierarchic levels: Core K-grid layer and High-level K-grid layer (Zhuge, 2002). The Core K-grid layer are services directly implemented on the top of generic grid services while High-level k-grid layer are services used to describe, develop, and execute PDKD calculations over the Knowledge Grid. It uses the simple grid services and defines a set of additional layers to the services of distributed knowledge discovery on universally connected computers where each node can be a parallel machine. Knowledge grid allows the alliance of scientists, organizations and enterprises to mine data stored in diverse data warehouses located in different company or establishments (Cannataro & Talia, 2003; Cannataro, Talia, & Trunfio, 2001; Zaki, 2000).
Presently, the Grid is used for scientific applications as well as industrial and commercial applications (Cannataro & Talia, 2003). Computational grids are emerging substructure that enables the incorporated use of remote high-end computers, databases, scientific instruments, networks and other resources (Chervenak, Foster, Kesselman, Salisbury, & Tuecke, 2001; Foster & Kesselman, 2004). Grid applications involve large amounts of computing and/or data (Zhuge, 2002). The basic reason for the architecture design of the Knowledge Grid includes Data heterogeneity and large data-set-handling; Algorithm integration and independence; Compatibility with grid infrastructure and grid awareness; Openness; Scalability; Security and data privacy (Cannataro & Talia, 2003).
Knowledge Grid technology has been adopted to build efficient and effective intelligent platform for information retrieval, filtering and mining (Cannataro & Talia, 2003; Zhuge, 2002). Hence, a knowledge management system can be built based on the KG framework for extensive knowledge gathering, sharing, managing and coordination for Nigerian universities.
Grid technology has been in existence for many years and been implemented in many countries around the globe. Below are few examples: Zhuge in (Zhuge, 2002) developed a knowledge grid model for sharing and managing globally distributed knowledge resources. This model arranged knowledge in three dimensional knowledge spaces (i.e. Category, Level and Location) and provided a knowledge grid operational language (KGOL). The model enabled people to conveniently share knowledge on the internet with one another however the operation of the knowledge depends on the standardization of the knowledge categories to some level.
Owoc and Weichbroth in (Owoc & Weichbroth, 2015) developed a multi-dimensional knowledge space model that distributed and managed knowledge resources among scholars and students. This hybrid technique used web log analysis and context-aware knowledge. This model ensured fast search for data in a multi-way channel however there are some problems like sparsity, cold-start and efficiency issues.
Cannataro, Talia and Trunfio in (Cannataro et al., 2001) designed a parallel and distributed knowledge discovery system called Knowledge grid which combines data mining techniques and computational grid resources. This allowed the cooperation of scientists across different research centres to mine data and also use knowledge management system. Its main advantage is that, it speeds up headway on very large-scale geographically distributed data mining. Its shortcoming is that it cannot handle petabyte-scale application.
A summary of various applied grid technologies that have been developed and applied in countries abroad for knowledge management in different areas is presented in Table 1.

Deductions from Reviewed Literature
The follows are the deductions from the reviewed literature:
A number of factors have been reported in past works (Murumba & Micheni, 2017; Uzoka et al., 2011) to be responsible for poor adoption and use of grid technology as a platform for implementing knowledge management system in Nigerian tertiary institutions. Though there are few research works on development of conceptual frameworks for grid computing for information sharing in Nigerian context but none of these is implemented in real life. None adoption and implementation of KG is attributed to the following challenges (Awosan, 2014; Micheni & Murumba, 2016; Sanjay Misra & Adewumi, 2015; Ohiorenoya & Eboreime, 2014; Uzoka, Akinnuwesi, Olabiyisi, & Demilade, 2012): The cost of building knowledge Grid is very high; Building a knowledge Grid is complex; Tertiary institution wants to have autonomy, and Knowledge Grid allow resource sharing, which some institutions may not support because of issues of ownership, copyrights, and licensing; Poor Information Technology infrastructures that support Knowledge Grid Technology; Lack of awareness about the advantages of Knowledge Grid technologies; Lack of Information Technology professionals that can use knowledge grid technology; Knowledge Grid services are susceptible to attackers; Unstable power supply; Lack of trust of grid service provider, Inconsistency and high cost of internet, Future increase in cost of grid computing, Poor infrastructure, Lack of technical skilled personnel etc.
Knowledge Grid allows easy access to the centralized or distributed computing resources.
The KG technology fast-track progress for very large-scale geographically distributed knowledge mining by permitting the incorporation of numerous currently incoherent approaches and technologies (Cannataro & Talia, 2003). Knowledge Grid technology was adopted to build efficient and effective intelligent platform for information retrieval, filtering and mining (Cannataro & Talia, 2003; Zhuge, 2002).
Knowledge Grid had been developed for the implementation of Parallel and Distributed Knowledge Discovery (PDKD) systems on top of grid systems such as the Globus Toolkit and Legion (Cannataro & Talia, 2003). It allows executions of high-performance data intensive in distributed and parallel applications.
Knowledge-grid systems allow resource sharing. It brings faster and easier transfer of files between collaborators at different universities. It makes use of knowledge discovery and Grid technologies. Therefore, allow sharing of knowledge among the individual scholar and organisation in the grid platform.
Knowledge Grid technology allows virtual collaboration of resource across individual organisation that are linked together in the grid platform. Knowledge grid allows the alliance of researchers to mine data stored in different research centres and also analysts that use knowledge management system function on diverse data warehouses located in different universities (Cannataro & Talia, 2003; Cannataro et al., 2001). This in turn will increase research works among scholars and hence enhance global development.
Security and data privacy issues are important features in wide area distributed systems. The knowledge grid services have valid support to cope with user authentication, security and data privacy. Basic grid functionality (e.g., Globus security infrastructure – GSI) is able to provide secure client-server communications without affecting the usability of the grid infrastructure and services(Cannataro et al., 2001).
Knowledge grid allows the incorporation of different data mining algorithms and these algorithms are autonomous from the data mining algorithms used for knowledge mining (Cannataro et al., 2001).
Knowledge Grid system will promotes knowledge-driven economy to achieve quality, efficiency and ultimately leverage on competitive edge. The implementation of Knowledge Grid system will also bring global contributions to the world development, especially Nigerian economic development. Despite Knowledge Grid importance globally, the attention that Nigerian society had given to it is poor, feeble and unsteady, which in turn had affected its knowledge management efficiency and economic development (Ohiorenoya & Eboreime, 2014).
Knowledge grid is constructed on top of computational grid that provides reliable and ubiquitous access to high-end computational resources. KG is built on the use of high-bandwidth communication networks and high-performance parallel computers for the purpose of mining data. It uses the simple grid services and defines a set of additional layers for the services of distributed knowledge discovery on universally connected computers where each node can be a parallel machine. This technology is particularly useful for large organizations, environments and enterprises that manage and analyse data that are geographically distributed in different data repositories or warehouses (Micheni & Murumba, 2016). Grid applications often involve large amounts of data, and this requires much of Internet and Web infrastructures.
Knowledge Grid provide user-friendly interaction with users and make it easier for virtual collaboration among the Universities on the Grid. This will brings organisational efficiency, allow a platform to share and manage information/knowledge.
Other implications of implementing Knowledge Grid in Nigerian Universities include the followings: faster and easier transfer of files between the collaborators at different geographical location of their universities; Easier access to distributed computational resources on the Knowledge Grid; allow mining of knowledge from the Knowledge Grid; improve Nigerian economy and in turn global economy; permit virtual collaboration of individual University as a collaborator and can allow participation from their various locations.
The development and growth of any organisation is determined by the knowledge management system employed. Thus building a platform for collaboration and knowledge sharing among Nigerian Universities using knowledge Grid will be of great importance especially to the academic environment. Knowledge grid system had been implemented in developed nations in Europe and Asia as presented in Table 1, but had not yet been implemented in Nigeria as in Table 2. As mentioned above, there are numerous advantages of Knowledge grid to Nigerian Universities. Despite the importance of knowledge grid system globally, the attention that Nigerian universities give to knowledge management using knowledge grid is poor, feeble and unsteady and hence poor collaboration and knowledge sharing among the universities. Therefore, there is great need for Nigerian organisations especially academic institutions to decide and improve organizational practices, principles, procedures, and methodologies on how knowledge can be created, shared, managed, and distributed. There are research opportunities in this area, and thus our future work will be to develop a knowledge grid system for Nigerian Universities that will allow collaboration among the Universities in Nigeria and hence facilitate knowledge sharing.
