Natural language understanding (NLU) is a branch of artificial intelligence that uses computer software to understand human language input. A basic form of NLU is called parsing, which takes written text and converts it into a structured format for computers to understand. This allows computers to comprehend and respond to human language instead of relying on computer programming languages. Key components of NLU include intent recognition, which identifies a user's objective from their text, and entity recognition, which identifies and extracts information about important entities mentioned in a message. NLU plays a vital role in developing artificial intelligence for chatbots by enabling them to understand human language.
Natural language processing (NLP) is a way for computers to analyze, understand, and derive meaning from human language. NLP utilizes machine learning to automatically learn rules by analyzing large datasets rather than requiring hand-coding of rules. Common NLP tasks include summarization, translation, named entity recognition, sentiment analysis, and speech recognition. NLP works by applying algorithms to identify and extract natural language rules to convert unstructured language into a form computers can understand. Main techniques used in NLP are syntactic analysis to assess language alignment with grammar rules and semantic analysis to understand meaning and interpretation of words.

1. Turing Test:
The Turing Test, proposed by Alan Turing TURING TEST (1950),
was designed to provide a satisfactory operational definition of
intelligence.
A computer passes the test if a human interrogator, after posing
some written questions, cannot tell whether the written
responses come from a person or from a computer.
The computer would need to possess the following capabilities:
• natural language processing to enable it to communicate
successfully in English;
• knowledge representation to store what it knows or hears;
• automated reasoning to use the stored information to answer
questions and to draw
• machine learning to adapt to new circumstances and to detect
and extrapolate patterns.
• computer vision to perceive objects, and
• robotics to manipulate objects and move about.
Turing’s test deliberately avoided direct physical interaction
between the interrogator and the computer, because physical
simulation of a person is unnecessary for intelligence. However,
the so-called total Turing Test includes a video signal so that
the interrogator can test the subject’s perceptual abilities, as well
as the opportunity for the interrogator to pass physical objects
“through the hatch.”
Drawbacks of the Turing test
Human vs. general intelligence (humans sometimes act
unintelligently, while intelligent behaviour does not
necessarily have to be human)
Real vs. simulated intelligence (a philosophical argument for
Behaviourally oriented AI)
Naivety of the question asker (proven in the case of ELIZA-
bot)
Irrelevance of the test
Irrelevance of the test
Aeronautics textbooks don't define aeronautics as:
Building machines that y so similarly to pigeons that they can
fool other pigeons."
2. TT is perhaps more significant for the philosophy than for
the development of AI
What is Artificial Intelligence?
According to the father of Artificial Intelligence, John McCarthy,
it is “The science and engineering of making intelligent machines,
especially intelligent computer programs”.
Artificial Intelligence is a way of making a computer, a
computer-controlled robot, or a software think intelligently,
in the similar manner the intelligent humans think.
AI is accomplished by studying how human brain thinks, and how
humans learn, decide, and work while trying to solve a problem,
and then using the outcomes of this study as a basis of developing
intelligent software and systems.
Goals of AI
To Create Expert Systems − The systems which exhibit
intelligent behavior, learn, demonstrate, explain, and advice
its users.
To Implement Human Intelligence in Machines − Creating
systems that understand, think, learn, and behave like
humans.
What is AI Technique?
AI Technique is a manner to organize and use the knowledge
efficiently in such a way that −
It should be perceivable by the people who provide it.
It should be easily modifiable to correct errors.
It should be useful in many situations though it is
incomplete or inaccurate.
Applications of AI
AI has been dominant in various fields such as −

Structure And Types of Intelligent Agents
An agent is anything that can perceive its environment
through sensors and acts upon that environment
through effectors. It is a device with sensors and actuators, for
example : a robotic car, a camera, a PC. Agent program is an
implementation of an agent function. An agent function is a map
from the percept sequence(history of all that an agent has
perceived till date) to an action.
Agent = Architecture + Agent Program
perceiving its environment through sensors and
acting upon that environment through actuators
4. A human agent has sensory organs such as eyes, ears, nose,
tongue and skin parallel to the sensors, and other organs
such as hands, legs, mouth, for effectors.
A robotic agent replaces cameras and infrared range finders
for the sensors, and various motors and actuators for
effectors.
A software agent has encoded bit strings as its programs
and actions.
The Structure of Intelligent Agents
Agent’s structure can be viewed as −
Agent = Architecture + Agent Program
Architecture = the machinery that an agent executes on.
Agent Program = an implementation of an agent function.
Simple Reflex Agents
They choose actions only based on the current percept.
They are rational only if a correct decision is made only on
the basis of current precept.
Their environment is completely observable.
Condition-Action Rule − It is a rule that maps a state (condition) to
an action.
5. Model Based Reflex Agents
They use a model of the world to choose their actions. They
maintain an internal state.
Model − The knowledge about “how the things happen in the
world”.
Internal State − It is a representation of unobserved aspects of
current state depending on percept history.
Updating the state requires the information about −
How the world evolves.
How the agent’s actions affect the world.
6. Goal Based Agents
They choose their actions in order to achieve goals. Goal-based
approach is more flexible than reflex agent since the knowledge
supporting a decision is explicitly modeled, thereby allowing for
modifications.
Goal − It is the description of desirable situations.
Utility Based Agents
They choose actions based on a preference (utility) for each state.
Goals are inadequate when −
7. There are conflicting goals, out of which only few can be
achieved.
Goals have some uncertainty of being achieved and you need
to weigh likelihood of success against the importance of a
goal.
What is NLP?
Natural Language Processing (NLP) refers to AI method of
communicating with an intelligent systems using a natural
language such as English.
Processing of Natural Language is required when you want an
intelligent system like robot to perform as per your instructions,
when you want to hear decision from a dialogue based clinical
expert system, etc.The field of NLP involves making computers to
perform useful tasks with the natural languages humans use.
The input and output of an NLP system can be −
Speech
Written Text
8. Components of NLP
There are two components of NLP as given −
Natural Language Understanding (NLU)
Understanding involves the following tasks −
Mapping the given input in natural language into useful
representations.
Analyzing different aspects of the language.
Natural Language Generation (NLG)
It is the process of producing meaningful phrases and sentences
in the form of natural language from some internal
representation.
It involves −
Text planning − It includes retrieving the relevant content
from knowledge base.
Sentence planning − It includes choosing required words,
forming meaningful phrases, setting tone of the sentence.
Text Realization − It is mapping sentence plan into
sentence structure.
The NLU is harder than NLG.
Difficulties in NLU
NL has an extremely rich form and structure.
It is very ambiguous. There can be different levels of ambiguity −
Lexical ambiguity − It is at very primitive level such as
word-level.
For example, treating the word “board” as noun or verb?
Syntax Level ambiguity − A sentence can be parsed in
different ways.
For example, “He lifted the beetle with red cap.” − Did he use
cap to lift the beetle or he lifted a beetle that had red cap?
9. Referential ambiguity − Referring to something using
pronouns. For example, Rima went to Gauri. She said, “I am
tired.” − Exactly who is tired?
One input can mean different meanings.
Many inputs can mean the same thing.
*For INFORMATION Only NLP Terminology
Phonology − It is study of organizing sound systematically.
Morphology − It is a study of construction of words from
primitive meaningful units.
Morpheme − It is primitive unit of meaning in a language.
Syntax − It refers to arranging words to make a sentence. It
also involves determining the structural role of words in the
sentence and in phrases.
Semantics − It is concerned with the meaning of words and
how to combine words into meaningful phrases and
sentences.
Pragmatics − It deals with using and understanding
sentences in different situations and how the interpretation
of the sentence is affected.
Discourse − It deals with how the immediately preceding
sentence can affect the interpretation of the next sentence.
World Knowledge − It includes the general knowledge about
the world.
Steps in NLP
There are general five steps −
Lexical Analysis − It involves identifying and analyzing the
structure of words. Lexicon of a language means the
collection of words and phrases in a language. Lexical
analysis is dividing the whole chunk of txt into paragraphs,
sentences, and words.
10. Syntactic Analysis (Parsing) − It involves analysis of words
in the sentence for grammar and arranging words in a
manner that shows the relationship among the words. The
sentence such as “The school goes to boy” is rejected by
English syntactic analyzer.
Semantic Analysis − It draws the exact meaning or the
dictionary meaning from the text. The text is checked for
meaningfulness. It is done by mapping syntactic structures
and objects in the task domain. The semantic analyzer
disregards sentence such as “hot ice-cream”.
Discourse Integration − The meaning of any sentence
depends upon the meaning of the sentence just before it. In
addition, it also brings about the meaning of immediately
succeeding sentence.
Pragmatic Analysis − During this, what was said is re-
interpreted on what it actually meant. It involves deriving
those aspects of language which require real world
knowledge.
11. What is Reasoning And its types?
Reasoning − It is the set of processes that enables us to
provide basis for judgement, making decisions, and
prediction. There are broadly two types –
Table 2
Inductive Reasoning Deductive Reasoning
It conducts specific
observations to makes
broad general
statements.
Even if all of the
premises are true in a
statement, inductive
reasoning allows for the
conclusion to be false.
Example − "Nita is a
teacher. Nita is
studious. Therefore, All
teachers are studious."
It starts with a general
statement and examines
the possibilities to reach a
specific, logical conclusion.
If something is true of a
class of things in general, it
is also true for all members
of that class.
Example − "All women of
age above 60 years are
grandmothers. Shalini is
65 years. Therefore, Shalini
is a grandmother."
Hill Climbing And Its limitations
The hill-climbing search algorithm (steepest-ascent
version) .It is simply a loop that continually moves in the
direction of increasing value—that is, uphill. It terminates
when it reaches a “peak” where no neighbor has a higher
value.
The algorithm does not maintain a search tree, so the data
structure for the current node need only record the state
and the value of the objective function.
Hill climbing does not look ahead beyond the immediate
neighbors of the current state. This resembles trying to find
the top of Mount Everest in a thick fog while suffering from
amnesia.
12. Hill-climbing algorithms typically choose randomly among
the set of best successors if there is more than one.
Hill climbing is sometimes called greedy local search
because it grabs a good neighbour state without thinking
ahead about where to go next. Although greed is considered
one of the seven deadly sins, it turns out that greedy
algorithms often perform quite well.
Hill climbing often makes rapid progress toward a solution
because it is usually quite easy to improve a bad state.
Limitations
Unfortunately, hill climbing often gets stuck for the following
reasons:
Local maxima: a local maximum is a peak that is higher
than each of its neighboring states but lower than the global
maximum. Hill-climbing algorithms that reach the vicinity
of a local maximum will be drawn upward toward the peak
but will then be stuck with nowhere else to go.
Ridges: Ridges result in a sequence of local maxima that is
very difficult for greedy algorithms to navigate.
Plateaux: a plateau is a flat area of the state-space
landscape. It can be a flat local maximum, from which no
uphill exit exists, or a shoulder, from which progress is
possible. A hill-climbing search might get lost on the
plateau.
13. Prove Dfs and Bfs are special case for best for
search
14. Uniform Cost Search reduces to Breadth First Search when all
edges have the same cost.
15. best-first search reduces to Breadth-First Search when
f(n) = number of edges from start node to n,
to UCS when f(n) = g(n); it can be reduced to DFS by, for example,
setting f(n) = -g(n) (thus forcing deep nodes on the current branch
to be searched before shallow nodes on other branches).
A*Search reduces to UCS when the heuristic function is zero
everywhere, i.e. h(n) = 0 for all n;
this heuristic is clearly admissible since it always (grossly!)
underestimates the distance remaining to reach the goal.
