When we talk about method for link analysis, the issue that comes to one’s mind is the connection that is associated with gathering of methods that help with the operation of data used in the illustration in

119

nodes and links (Donoho, 2005). Some of the techniques according to Donoho (2005) comprises of subgraph matching, cliques and K-plexes, spread of effects, imagining, pivots and authorities, organisation, and alignment. The link analysis extends to presentation of social network analysis, virus-related, marketing strategy, Internet searches, fraud discovery, and crime deterrence (Donoho, 2005).

Another point of view according to Olson and Lauhoff (2019) was that, in link analysis, what is mostly considered is the relationship that exists between units in a network. This becomes fascinating when dealing with social network analysis. This has been used several times to find out the degree of proportion in social relationship that cut across social media and collaboration networks (Olson & Lauhoff, 2019). In this context, people could be characterised as nodes and the connection among them can be link to graph. Link analysis has been used in diverse context and subject areas, such as biological science, to examine protein interactions, law enforcement and terrorism, business and computer sciences. With the aid of link analysis, it is possible to determine the growth analysis through forecast of where the graph is going or possibly determine where the clients are heading, actually permitting the systems to intermingle with the customers to increase the likelihood of their purchasing goods or items (Olson & Lauhoff, 2019). Furthermore, link analysis could also be attributed to addition of web pages already in use based on direction of information or items. In order words, a crawler strategy or robot/spider performing a traversal of the network graph by means of attractive high-quality pages. When one page has been fetched, the link would have to decide which page available of the regular uncrawled pages to draw next (Olson & Lauhoff, 2019).

Loshin (n.d.), story is similar, but distinct compared to previously represent. Link analysis according to Loshin (n.d.) denotes the existence of link in different dimension and everywhere. There are basically two types of links, which are the internal and external. The internal link deals with when you are required to link one page on your website to another but not necessarily departing from the same area. While the external showcase the linkage of your website page to that of offline domain. However, in order to understand this scenario very well, below is the practical attestable method of link analysis. This comprises of physical (i) (people: family, friends, seminar or conference attendees), (ii) objects: telephones, computers, mobile phones etc), (iii) online:

Internet, graphs etc (Loshin, n.d.). The different kinds of link mentioned have some designation, breakdown and assessment performance patterns for their activities.

The view that surrounds the connectivity of the different link analysis mentioned is fascinating, particularly when we consider individuals and

120

additional kinds of parties, as well as the understanding that could be derived from the connections. For instance, if we have to examine the numbers of people that we are linked to, let say 1000 people. It could also be seen that this 1000 people are linked to other people whom we might not know of and this is how link analysis grows. Can we say that or is it accurate to say that the people you are connecting to, might be different from mine. Therefore, it could be deduced that link analysis is subject to the fact that, those who you are connected to might somehow be connected to me as well through the chain of social network analysis.

Relating this to library context, it is evident to know that, numerous applications of this nature is associated with social network being the backbone of enhanced service delivery in present day information and knowledge economy. Most of the users in libraries are also linked to one another hence some users share their resources with one another.

CONCLUSION

It is interesting to note that, social network analysis, its implications and network service providers has become a fascinating discourse in this study unit due to the intricacies surrounding its operations. There are no way libraries or any other organisation could survive without the strength which Internet service provider offer in reorganising their operations in service delivery. Librarians in the bid to perform their daily task rely heavily on social network. Therefore, based on the analysis surrounding activities of social network where nodes and algorithms are required, its incorporation in libraries becomes indispensable.

5.0 SUMMARY

This unit examined the social network analysis, implications and network service providers in libraries. The reason that necessitate this was based on the understanding that surrounds social network analysis (SNA), which involves analysing interactions and activities social network over a certain period of time. The feature of network incorporates nodes and algorithms. Since social network has the characteristic of different numerical methods its analysis of data usage

121

becomes imperative. It was established that, SNA measures the flow of data usage in social network in order to regulate its approach. This was based on the behaviour of personnel involved in associations within the network arrangement. In the light of the shrewd analogy, several implications regarding social network analysis were identified, to include: offers understanding among teams’ users, use of tactical methods, treaties with social systemic, analysis of electronic traces and join diverse groups of people together, among others. Recall that, social network analysis is significant; therefore, the need to have a network service provider cannot be undermined in proper reorganisation of the effect expected from social network.

The network service provider (NSP) being a recognised institution licence for such operations is expected to proffer connectivity of internet services to the individual and organisation, of which libraries are inclusive. Among the NSP registered in Nigeria for operations are:

Spectranet, Tizeti, Ipnx, Cobranet Limited, VDT communications, Vodacom, Hyperia, MainOne, Information Connectivity Solutions Limited (ICSL), Excelsimo Networks, Telkom and MTN. In the same vein, large scale network data, models for network structure and methods for link analysis were also discussed.
