Abstract
The hyperlinked display list of search results from any given search
engine is an illusion of the real order in priority if its position is
based on a pageRank computation. This is because, several factors
governs the pageRank computation. Besides the fact that different
search engines fashions their ranking model, it is an established fact
that, the hub and authority factor must be considered. This paper
considered the effects of an in-bound (authority) and out-bound (hub)
links on the rank of a page. Hyperlink-Induced Topic Search (HITS)
(also known as hubs and authorities) is a link analysis algorithm that
rates Web pages, developed by Jon Kleinberg (1999). It was a precursor
to PageRank. The idea behind Hubs and Authorities stemmed from a
particular insight into the creation of web pages when the Internet was
originally forming; that is, certain web pages, known as hubs, served
as large directories that were not actually authoritative in the
information that it held, but were used as compilations of a broad
catalog of information that led users directly to other authoritative
pages. In other words, a good hub represented a page that pointed to
many other pages, and a good authority represented a page that was
linked by many different hubs. A good hub page is one that points to
many good authorities; a good authority page is one that is pointed to
by many good hub pages. We focused on the Google’s Toolbar with
regard to pages given a certain toolbar Page Rank, but with an inbound
link from a page that has a toolbar Page Rank, which is higher by one.
This is done to alleviate the effect of the removal from the
database(s), pages with no outbound links as proposed by Page and Brin,
and applied by Google for the normalization of the dangling links. We
considered, six (6) Web site clips scenarios to show the effects of
inbound and outbound links, vis a vis the number of Pages in the Web,
and the influence of the Damping Factor. We observed that the linkage
of sets of dangling sites/pages (PDF, MS-word infested pages) and the
application of a new ranking model for them is better in smoothening,
the hub and authority complimentary effects in page ranking. We gave
recommendations on how search engines and crawlers could weight and
produce a better ranking of pages for users. Thus, users can within the
first few search results, get to their expected search results.
