Q91.
A white space may act as a boundary to derive primitive sequence.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:When aggregated data is available, primitive sequence may be derived by selecting an atomic symbol as a boundary. In a text based system, a white space is regarded as a boundary for generating primitive sequence. For example, white spaces are employed to separate words in text.
Q92.
What application is supported by IBM research tool XTAG?

a.

Data analysis

b.

Natural Language Processing

c.

Machine learning

d.

Artificial Intelligence

Discuss
Answer: (b).Natural Language Processing Explanation:An XTAG system is a grammar development tool based on Tree Adjoining Grammar (TAG). It consists of a parser, an X-window grammar development interface, and a morphological analyser. Other tools include SNeps , AGFL, and PC KIMMO which may be employed for natural language processing.
Q93.
How does the cognitive radio access the a priori models?

a.

Chat box

b.

Handshake mechanism

c.

Requests

d.

Mappings

Discuss
Answer: (d).Mappings Explanation:The cognitive radio access the a priori models using mappings that exist between the word, phrase, dialog, and scene levels of the observation phase hierarchy and the encapsulated speech components.
Q94.
What is an architecture map?

a.

Architecture map describes the internal structure of cognitive radio

b.

Architecture map describes the sequence of events that occur between stimulus and response

c.

Architecture map describes the flow of inference from observation to act phase

d.

Architecture map represents cognition functions implemented using cognition components

Discuss
Answer: (d).Architecture map represents cognition functions implemented using cognition components Explanation:Architecture map represents cognition functions implemented using cognition components. It consists of data structures, processes, and flows which are represented using topological maps over abstract domains.
Q95.
Why should a cognitive radio be capable of differentiating “User” and “Things” entities?

a.

To properly filter the signals

b.

To offer different levels of priority

c.

To amplify the signals

d.

To re-direct the signals

Discuss
Answer: (b).To offer different levels of priority Explanation:The architecture model builds an environment consisting of world, cognitive radio, and a world model within the cognitive radio. The world is composed of entities such as user, home network, people, things, networks, etc. The cognitive radio must be capable differentiating these entities to respond in accordance to pre-determined priority levels.
Q96.
What is a known sequence?

a.

The known sequence refers to the currently recorded stimulus from the outside world

b.

The known sequence refers to the immediate past stimulus from the outside world

c.

The known sequence refers to a series of stimuli from the outside world

d.

The known sequence refers to integrated knowledge of the cognitive radio

Discuss
Answer: (d).The known sequence refers to integrated knowledge of the cognitive radio Explanation:The known sequence corresponds to context cluster sequence of the inference hierarchy. The known sequence refers to the integrated knowledge present in the cognitive behaviour model of cognitive radio.
Q97.
What are the constituents of a known sequence?

a.

Radio Knowledge Representation Language frames

b.

Knowledge Query and Manipulation Language frames

c.

Radio eXtensible Markup Language frames

d.

Web Ontology Language frames

Discuss
Answer: (a).Radio Knowledge Representation Language frames Explanation:Known sequence describes the integrated knowledge of cognitive radio. The known sequence is developed by embedding Radio Knowledge Representation Language (RKRL) frames in the cognitive radio. It is also possible to develop known sequence through independent machine learning.
Q98.
Which among the following is the definition of novel sequence?

a.

Novel sequence is a record of types of response generated by cognitive radio

b.

Novel sequence is a record of types of stimulus encountered by cognitive radio

c.

Novel sequence describes the current stimulus-response of cognitive radio

d.

Novel sequence is the integration of current stimulus-response and known sequence

Discuss
Answer: (c).Novel sequence describes the current stimulus-response of cognitive radio Explanation:Novel sequence corresponds to the content cluster level of inference hierarchy. It describes the current stimulus-response unit of cognitive behaviour model. The highest level of sequence unit “Scenes” is composed of known sequence and novel sequence.
Q99.
Which among the following is a data structure included in the architecture map in addition to the general structure of cognition cycle?

a.

Decide

b.

Dialog state

c.

Act

d.

Plan

Discuss
Answer: (b).Dialog state Explanation:The cognitive radio section of the architecture map is composed of sequences of inference hierarchy, world model composed of bindings between a-priori data structures and the current scene, and phases of cognition. Dialog states, action requests, plans, and action are additional data structures added to support the phases of cognition cycle.
Q100.
Which among the following is not a part context section of a RKRL frame?

a.

Uniform Resource Locator

b.

Time

c.

Location of frame

d.

Stimulus

Discuss
Answer: (d).Stimulus Explanation:The cognition functions and phases are represented using data structures. The data structures are mapped to RKRL frames which are made up of handle, model, body, resources, and context. The handle may correspond to a set or a stimulus. The body may correspond to a subset or a response. The context may correspond to a URL, source, time or location.
