,Q1 ANALYZE COMPLEX INFORMATION NEEDS AND FORMULATE EFFECTIVE SEARCH
STRATEGIES
A researcher seeks studies on the effect of social media on adolescent mental
health, but a preliminary search returns mostly opinion pieces. Which search
tactic BEST leverages controlled vocabulary to improve precision?
A. Use free-text terms with truncation to broaden recall.
B. Apply a subject heading like 'Social Media' combined with 'Adolescent Psychology' and
restrict to peer-reviewed. CORRECT
C. Search only in full-text databases to capture all mentions.
D. Skip controlled vocabulary and rely on citation chasing.
RATIONALE: Controlled vocabulary (subject headings) organizes content by concept, improving
precision. Broadening recall (A) or full-text (C) increases noise. Citation chasing (D) is
supplementary, not a primary precision tactic.
Q2 ANALYZE COMPLEX INFORMATION NEEDS AND FORMULATE EFFECTIVE SEARCH
STRATEGIES
In a Boolean search, a user runs 'apple AND fruit' and retrieves 500 results. To
reduce false drops caused by polysemy, which refinement is MOST effective?
A. Change AND to OR to include more synonyms.
B. Use phrase searching: 'apple fruit'.
C. Add NOT with 'computer' to exclude the tech company. CORRECT
D. Use a field tag like 'apple' in the title field.
RATIONALE: Polysemy (multiple meanings) is addressed by excluding irrelevant contexts (NOT
'computer'). Phrase searching (B) doesn't resolve ambiguity. Title field (D) may miss relevant
items. OR (A) worsens recall.

,Q3 ANALYZE COMPLEX INFORMATION NEEDS AND FORMULATE EFFECTIVE SEARCH
STRATEGIES
Given a query 'cancer treatment', a search engine returns 100 documents.
Precision is 0.8 and recall is 0.6. How many relevant documents exist in the
collection?
A. 80
B. 60
C. 120
D. 133 CORRECT
RATIONALE: Precision = relevant retrieved / total retrieved -> 0.8 = relevant retrieved / 100 ->
relevant retrieved = 80. Recall = relevant retrieved / total relevant -> 0.6 = 80 / total relevant ->
total relevant = .6 = 133.33 133.
Q4 ANALYZE COMPLEX INFORMATION NEEDS AND FORMULATE EFFECTIVE SEARCH
STRATEGIES
A librarian is designing a search for a systematic review on 'telemedicine in rural
areas'. Which search structure BEST balances sensitivity and specificity?
A. Use a single broad term 'telemedicine'.
B. Combine synonyms with OR, then AND with 'rural'. CORRECT
C. Limit to one database and use 'rural' as a keyword.
D. Use only MeSH terms without free-text.
RATIONALE: Systematic reviews require high recall; OR-ing synonyms captures variations, and
AND with 'rural' maintains specificity. A single term (A) misses synonyms; one database (C) limits
coverage; MeSH only (D) may miss newer terms.

, Q5 ANALYZE COMPLEX INFORMATION NEEDS AND FORMULATE EFFECTIVE SEARCH
STRATEGIES
In a vector space model, query 'information retrieval' is represented as (0.5, 0.8,
0.2) and a document as (0.4, 0.6, 0.1). What is the cosine similarity?
A. 0.98 CORRECT
B. 0.92
C. 0.85
D. 0.79
RATIONALE: Cosine = dot product / (||q|| * ||d||). Dot = 0.5*0.4 + 0.8*0.6 + 0.2*0.1 = 0.20 + 0.48
+ 0.02 = 0.70. ||q|| = sqrt(0.25+0.64+0.04)=sqrt(0.93)=0.964. ||d|| =
sqrt(0.16+0.36+0.01)=sqrt(0.53)=0.728. Product = 0.702. Cosine = 0.70/0.702 0.997 0.98.
Q6 ANALYZE COMPLEX INFORMATION NEEDS AND FORMULATE EFFECTIVE SEARCH
STRATEGIES
Which of the following is the PRIMARY purpose of stemming in search systems?
A. To reduce index size by removing stop words.
B. To conflate morphological variants to improve recall. CORRECT
C. To rank results by term frequency.
D. To eliminate synonyms from the vocabulary.
RATIONALE: Stemming reduces words to root forms (e.g., 'running' to 'run'), improving recall by
matching variants. It doesn't remove stop words (A), rank (C), or handle synonyms (D).
