CBSE UGC NET July 2016 LIS Paper 2 (41-50)

1. 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.
Both (A) and (R) is true.
(A) is true, but (R) is false.
Both (A) and (R) are false.
(R) is true, but (A) is false.

2. Assertion (A) : Management is the efficiency in climbing the ladder of success.
Reason (R) : Leadership determines whether the ladder is leaning towards right wall.
(A) is true, but (R) is false.
(A) is false, but (R) is true.
Both (A) and (R) are true.
Both (A) and (R) are false.

3. 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 trans-formative force that is propelling libraries towards a new way to offer services.
A) is true, but (R) is false.
(A) is false, but (R) is true.
Both (A) and (R) are true.
Both (A) and (R) are false.

4. Assertion (A) : Consortia subscriptions are not always beneficial to libraries as publishers bundle irrelevant titles to inflate the number of titles for better price during negotiations.
Reason (R) : In bundled titles, libraries have not to pay for the titles which are not core to them.
(A) is true, but (R) is false.
(R) is true, but (A) is false.
Both (A) and (R) are true.
Both (A) and (R) are false.

5. 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.
(A) is true, but (R) is false.
(A) is false, but (R) is true.
Both (A) and (R) are false.
Both (A) and (R) are true.

Read the passage given below and answer the questions based on your understanding of the passage (Question Nos. 6 – 10) : 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-citations - the number of pages on the site having a link or links pointing to the same site. The difference between self-links and self-citations is that for self-citations a page with several self-links is counted with multiplicity one. The reason for counting self-citations 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-citation 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 self-citations (of authors in scientific publications), because self-links are often inserted for navigational purposes.

6. Self-links denote :
Links between two websites.
Links between two authors.
Links between source and the target of the page within the same site or domain.
Links between two articles written by two different authors.

7. Commercial search engines report
the number of pages with self-links
the number of self-links
the number of sites
the total number of total citations

8. Self-linking and self-linked measures calculate their rates for
Number of academic institutions on the web
Number of websites on the web
Number of databases available on a given site
Number of subject gateways on the web

9. Links in domain can lead to
a. different site on www
b. page in the same site
c. page in the different sites
d. all available e-documents
a and c are correct.
a and b are correct.
b and d are correct.
c and d are correct.

10. Reason for counting self-citations is
Academic
Classificatory
Technical
Non-technical
