  1. ASHAKEY
  2. BSRI
  3. CNLP
  4. DNone of these
Show answerHide answer

Correct answer: (C) NLP

Explanation

STRIPs was devised SRI in the early 1970s to control a robot called SHAKEY strips is not related with NLP (Natural Language Processing).

Q2UGC NET Computer Science, December 2014 (Paper II & III, Selected Questions)
_____ model is designed to bring prices down by increasing the number of customers who buy a particular product at once.
  1. AEconomic Order Quantity
  2. BInventory
  3. CData Mining
  4. DDemand-Sensitive Pricing
Show answerHide answer

Correct answer: (D) Demand-Sensitive Pricing

Explanation

Inventory and data mining have nothing to do with price. Economic Order Quantity (EOQ) is the order quantity that minimizes total holding and ordering costs. The demand-sensitive pricing model brings prices down as more customers buy the product at once.

Q3UGC NET Computer Science, June 2015 (Paper II & III, Selected Questions)
In which testing strategy requirements established during requirements analysis are validated against developed software?
  1. AValidation testing
  2. BIntegration testing
  3. CRegression testing
  4. DSystem testing
Show answerHide answer

Correct answer: (A) Validation testing

Explanation

Validation is "Are we building the right product? According to the capability maturity model Software validation : The process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements.

Q4UGC NET Computer Science, December 2015 (Paper II & III, Selected Questions)
_____ system is market oriented and is used for data analysis by knowledge workers including managers, Executives and analysts.
  1. AOLTP
  2. BOLAP
  3. CData system
  4. DMarket system
Show answerHide answer

Correct answer: (B) OLAP

Explanation

OLAP (Online Analytical Processing) is market oriented and used for data analysis by knowledge workers. It is characterized by a relatively low volume of transactions; queries are often very complex and involve aggregations; response time is an effectiveness measure; OLAP applications are widely used by data mining techniques.

Q5UGC NET Computer Science, August 2016 (Paper II & III, Selected Questions)
In Data mining, _____ is a method of incremental conceptual clustering.
  1. ASTRING
  2. BCOBWEB
  3. CCORBA
  4. DOLAD
Show answerHide answer

Correct answer: (B) COBWEB

Explanation

COBWEB is an incremental system for hierarchical conceptual clustering. COBWEB incrementally organizes observations into a classification tree. Each node in the classification tree represents a class (concept) and is labeled by a probabilistic concept that summarizes the attribute-value distribution of objects classified under the node.

Q6UGC NET Computer Science, August 2016 (Paper II & III, Selected Questions)
Criticism free idea generation is a factor of ______.
  1. ADecision Support System
  2. BGroup Decision Support System
  3. CEnterprise Resource Support System
  4. DArtificial Intelligence
Show answerHide answer

Correct answer: (B) Group Decision Support System

Explanation

Criticism-free idea generation is a feature of a group decision support system (GDSS).

Q7UGC NET Computer Science, November 2017 (Paper II & III, Selected Questions)
Which of the following is not a clustering method?
  1. AK–Mean method
  2. BSelf Organizing feature map method
  3. CK – nearest neighbor method
  4. DAgglomerative method
Show answerHide answer

Correct answer: (C) K – nearest neighbor method

Explanation

K-means, self-organizing feature maps and agglomerative methods are clustering methods. The k-nearest neighbour (K-NN) algorithm is a non-parametric method used for classification and regression, not clustering.

Q8UGC NET Computer Science, November 2017 (Paper II & III, Selected Questions)
In Artificial Intelligence (Al), which agent deals with happy and unhappy state?
  1. ASimple reflex agent
  2. BModel based agent
  3. CLearning agent
  4. DUtility based agent
Show answerHide answer

Correct answer: (B) Model based agent

Explanation

Note: a utility-based agent, which uses a utility function to distinguish happy and unhappy states, is the usual answer (option d); the book keys (b). The book states that the model-based agent deals with happy and unhappy states.
