This set of Information Retrival Techniques Multiple Choice Questions & Answers (MCQs) focuses on Information Retrival Techniques Set 5

Q1 | Walking off a man is an example of
  • resolution of forces
  • addition of vectors
  • subtraction of vectors
  • multiplication of vectors
Answer: resolution of forces
Explaination:
while walking, a person presses the ground with his feet slightly slanted in the backward direction. the ground exerts upon him an equal and opposite reaction. its horizontal component enables the person to move forward while the vertical component balances this weight.
Q2 | What is the extraction of the meaning of utterance?
  • syntactic
  • semantic
  • pragmatic
  • none of the mentioned
Answer: semantic
Explaination:
semantic analysis is used to extract the meaning from the group of sentences.
Q3 | What is the process of associating a FOL expression with a phrase?
  • interpretation
  • augmented reality
  • semantic interpretation
  • augmented interpretation
Answer: semantic interpretation
Explaination:
semantic interpretation is the process of associating a fol expression with a phrase.
Q4 | What is meant by compositional semantics?
  • determining the meaning
  • logical connectives
  • semantics
  • none of the mentioned
Answer: determining the meaning
Explaination:
compositional semantics is the process of determining the meaning of p*q from p, q and *.
Q5 | What is used to augment a grammar for arithmetic expression with semantics?
  • notation
  • dcg notation
  • constituent
  • all of the mentioned
Answer: dcg notation
Explaination:
dcg notation is used to augment a grammar for arithmetic expression with semantics and it is used to build a parse tree.
Q6 | How many verb tenses are there in the English language?
  • 1
  • 2
  • 3
  • 4
Answer: 3
Explaination:
there are three types of tenses available in english language are past, present and future.
Q7 | Which is used to mediate between syntax and semantics?
  • form
  • intermediate form
  • grammer
  • all of the mentioned
Answer: intermediate form
Explaination:
none.
Q8 | What is meant by quasi-logical form?
  • sits between syntactic and logical form
  • logical connectives
  • all of the mentioned
  • none of the mentioned
Answer: sits between syntactic and logical form
Explaination:
it can be translated into a regular first-order logical sentence, so that it sits between syntactic and logical form.
Q9 | interpretation?
  • logical term
  • complete logical sentence
  • both logical term & complete logical sentence
  • none of the mentioned
Answer: both logical term & complete logical sentence
Explaination:
some kind of sentence in the semantic interpretation can’t be logical term nor a complete logical sentence.
Q10 | What kind of interpretation is done by adding context-dependant information?
  • semantic
  • syntactic
  • pragmatic
  • none of the mentioned
Answer: pragmatic
Explaination:
none.
Q11 | Which of the following does not affect the software quality and organizational performance?
  • market
  • product
  • technology
  • people
Answer: market
Explaination:
market is a collection of competitors, stakeholders, users each having different views on the product. so it does not affect the software quality.
Q12 | The intent of project metrics is:
  • minimization of development schedule
  • for strategic purposes
  • assessing project quality on ongoing basis
  • minimization of development schedule and assessing project quality on ongoing basis
Answer: minimization of development schedule and assessing project quality on ongoing basis
Explaination:
a project metric is a quantitative measure of the degree to which a system, component or process possesses an attribute.
Q13 | Which of the following is not a direct measure of SE process?
  • efficiency
  • cost
  • effort applied
  • all of the mentioned
Answer: efficiency
Explaination:
efficiency is an indirect measure.
Q14 | Which of the following is an indirect measure of product?
  • quality
  • complexity
  • reliability
  • all of the mentioned
Answer: all of the mentioned
Explaination:
all the mentioned options are indirect measures of a product.
Q15 | In size oriented metrics, metrics are developed based on the                                         
  • number of functions
  • number of user inputs
  • number of lines of code
  • amount of memory usage
Answer: number of lines of code
Explaination:
none.
Q16 | Which of the following is not an information domain required for determining function point in FPA ?
  • number of user input
  • number of user inquiries
  • number of external interfaces
  • number of errors
Answer: number of errors
Explaination:
fpa includes five domains namely input, output, inquiries, interface and logical files.
Q17 | Usability can be measured in terms of:
  • intellectual skill to learn the system
  • time required to become moderately efficient in system usage
  • net increase in productivity
  • all of the mentioned
Answer: all of the mentioned
Explaination:
none.
Q18 | A graphical technique for finding if changes and variation in metrics data are meaningful is known as
  • dre (defect removal efficiency)
  • function points analysis
  • control chart
  • all of the mentioned
Answer: control chart
Explaination:
others options are formulas.
Q19 | Defects removal efficiency (DRE)depends on:
  • e – errors found before software delivery
  • d – defects found after delivery to user
  • both e and d
  • varies with project
Answer: both e and d
Explaination:
dre = e / (e + d).
Q20 | What’s the role of lyaopunov fuction?
  • to determine stability
  • to determine convergence
  • both stability & convergence
  • none of the mentioned
Answer: to determine stability
Explaination:
lyapunov is an energy function.
