(1 Mark)
What are the two essential dynamic components that are matched in a computerized Selective Dissemination of Information (SDI) system?
💡
Step-by-Step Explanation & Concept Rationale
An SDI system operates by continuously comparing 'User Interest Profiles' (keywords defining a patron's research scope) against 'Document Profiles' (metadata/abstract keywords of newly indexed publications) and generating notifications.

In library reference services, what is the key distinction between 'Ready Reference' and 'Long-Range Reference' service introduced by Dr. S. R. Ranganathan?
💡
Step-by-Step Explanation & Concept Rationale
Ranganathan classified reference services by duration: Ready reference provides rapid fact-finding (e.g., dates, definitions, capital cities) in under 5 minutes from almanacs/dictionaries, while Long-range reference requires extensive searching across diverse sources, taking hours, days, or weeks.

What Boolean operator is used in online information retrieval to broaden a search and retrieve records containing either of two terms?
💡
Step-by-Step Explanation & Concept Rationale
The Boolean OR operator widens search results (union of sets), retrieving documents containing term A, term B, or both. AND narrows the search (intersection), while NOT excludes unwanted records.
Q. 13
Library Science
Difficulty: Easy
(1 Mark)
Which Boolean search operator retrieves only those records where both specified terms appear simultaneously, thereby narrowing the search results?
💡
Step-by-Step Explanation & Concept Rationale
The AND operator specifies the intersection of two search concepts, restricting results to records that contain both keywords (e.g., 'pediatrics AND leukemia').
Q. 14
Library Science
Difficulty: Easy
(1 Mark)
In database search syntax, what is 'Truncation'?
💡
Step-by-Step Explanation & Concept Rationale
Truncation (wildcard searching at the end of a stem word) allows searching for all morphological variants and singular/plural forms of a root term simultaneously.
Q. 15
Library Science
Difficulty: Medium
(1 Mark)
What do 'Proximity Operators' (such as NEAR, ADJ, or WITHIN) accomplish in bibliographic search engines?
💡
Step-by-Step Explanation & Concept Rationale
Proximity operators specify the spatial closeness of terms in the document text (e.g., 'climate NEAR/3 change' ensures the words occur within 3 words of each other), providing much higher precision than simple AND.

Who is recognized as the pioneer of citation indexing for science and founder of the Institute for Scientific Information (ISI) and Science Citation Index (SCI)?
💡
Step-by-Step Explanation & Concept Rationale
Dr. Eugene Garfield launched the Science Citation Index (SCI) in 1964 and founded ISI, creating citation tracking and the Journal Impact Factor (JIF) to map the interconnected web of scientific literature.
Q. 17
Library Science
Difficulty: Medium
(1 Mark)
How is the annual Journal Impact Factor (JIF) of an academic journal calculated for a given year (e.g., Year 2025)?
💡
Step-by-Step Explanation & Concept Rationale
The 2-year Journal Impact Factor equals: Citations in year N to items published in years (N-1) and (N-2), divided by the number of citable items (articles and reviews) published in years (N-1) and (N-2).

Who proposed the 'h-index' in 2005 to measure both the scientific productivity and citation impact of an individual researcher?
💡
Step-by-Step Explanation & Concept Rationale
Physicist Jorge E. Hirsch introduced the h-index in 2005. A scientist has an index h if h of his or her N papers have at least h citations each, and the other (N - h) papers have <= h citations each.
Q. 19
Library Science
Difficulty: Medium
(1 Mark)
If a researcher has published 10 research papers, and their papers have received 25, 18, 14, 10, 8, 7, 5, 3, 2, and 1 citations respectively, what is the researcher's h-index?
💡
Step-by-Step Explanation & Concept Rationale
Ranking papers by citations: 1st=25 (>=1), 2nd=18 (>=2), 3rd=14 (>=3), 4th=10 (>=4), 5th=8 (>=5), 6th=7 (>=6). The 7th paper has 5 citations, which is NOT >= 7. Thus, exactly 6 papers have at least 6 citations: h-index = 6.

What does the 'i10-index', popularized by Google Scholar, measure for an author?
💡
Step-by-Step Explanation & Concept Rationale

What classic bibliometric law states that if scientific journals are arranged in order of decreasing productivity of articles on a given subject, they divide into a core of journals and succeeding zones containing equal numbers of articles in the ratio 1 : n : n^2?
💡
Step-by-Step Explanation & Concept Rationale
Samuel C. Bradford published Bradford's Law in 1934, showing that a small core group of journals publishes the bulk of key papers in a discipline, while peripheral journals publish scattered related articles according to geometric zones 1 : n : n^2.

What does Lotka's Law (Alfred J. Lotka, 1926) describe in bibliometrics?
💡
Step-by-Step Explanation & Concept Rationale
Lotka's Law states that the number of authors producing x contributions is proportional to 1/x^2 (roughly 60% of authors publish only 1 paper, ~15% publish 2, and very few publish large numbers of papers).

What does Zipf's Law (George Kingsley Zipf) describe regarding word frequencies in natural language texts?
💡
Step-by-Step Explanation & Concept Rationale
Zipf's Law states that in natural human language texts, the rank of a word multiplied by its frequency is roughly constant (r * f = C). The most frequent word occurs roughly twice as often as the 2nd most frequent, and three times as often as the 3rd.
