41. Assertion (A) : Results from popular
web search engines are usually having high
recall, but an indexing database can provide high precision.
Reason
(R) : Indexing databases use controlled vocabulary which is a carefully
selected list of words and phrases which are used to tag units
of
information (document or
work) so that they may be more easily
retrieved.
Codes :
(1)
Both (A) and (R) is true.
(2) (A)
is true, but (R) is false.
(3)
Both (A) and (R) are false.
(4) (R)
is true, but (A) is false.
Ans: 1
42. Assertion (A) : Management is the
efficiency in climbing the ladder of success.
Reason
(R)
: Leadership determines whether the ladder is leaning towards right
wall.
Codes :
(1) (A)
is true, but (R) is false.
(2) (A) is false, but (R) is true.
(3)
Both (A) and (R) are true.
(4)
Both (A) and (R) are false.
Ans: 3
43. Assertion (A) : Web 2.0 is a good set
of economic, social and technological trend
that
collectively form the basis of the next
generation of the
Internet.
Reason
(R) : More than just the latest technology buzzword, Web 2.0 is a
transformative force
that is propelling libraries towards a new way to
offer services.
Codes :
(1) (A)
is true, but (R) is false.
(2) (A)
is false, but (R) is true.
(3)
Both (A) and (R) are true.
(4)
Both (A) and (R) are false.
Ans: 3
44. Assertion (A) : Consortia subscriptions
are not always beneficial to libraries as
publishers bundle irrelevant titles to inflate
the number of titles fr
better price
during negotiations.
Reason
(R) : In bundled titles, libraries have not to pay for the titles which are
not
core to them.
Codes :
(1) (A)
is true, but (R) is false.

is true, but (A) is false.
(3)
Both (A) and (R) are true.

Ans: 1
45. Assertion (A) : Chain procedure is a
systematic and almost mechanical method
of deriving
subject headings.
Reason (R)
: It does not always operate well only with a faceted scheme of
classification.
Codes :
(1) (A)
is true, but (R) is false.
(2) (A)
is false, but (R) is true.
(3)
Both (A) and (R) are false.

Read
the passage given below and answer the questions based on your understanding of
the passage (Question Nos. 46 – 50):
One
of the major features of the World Wide Web is the capability to create links
between pages. These links are often viewed as analogues of citations in
scientific publications (e.g. ROUSSEAU, 1997; BJORNEBORN & INGWERSEN, 2001;
CRONIN, 2001). Links can lead to a different site or may lead to a page in the
same site. Links for which the source and the target of the page are within the
same site or domain are called self-links. Instead of counting self-links, we
count self-sitations - the number of pages on the site having a link or links pointing
to the same site. The difference between self-links and self-sitations is that
for self-sitations a page with several self-links is counted with multiplicity
one. The reason for counting self-sitations instead of self-links is technical:
commercial search engines report the number of pages with self-links and not
the number of self-links. The term-sitation has been coined by ROUSSEAU (1997).
In this paper we develop the measures self-linking and self-linked, which
correspond to the classical measures for journals : self-citing and self-cited.
We calculate these rates for a number of academic institutions on the Web.
Self-links seems to be more problematic than selfcitations (of authors in
scientific publications), because self-links are often inserted for
navigational purposes.
46.
Self-links denote :
(1)
Links between two websites.
(2)
Links between two authors.
(3)
Links between source and the target of the page within the same site or domain.
(4)
Links between two articles written by two different authors.
Ans: 3
47.
Commercial search engines report
(1)
the number of pages with self-links
(2)
the number of self-links
(3)
the number of sites
(4)
the total number of total citations
Ans: 1
48.
Self-linking and self-linked measures calculate their rates for
