Description:-
A chatbot is a computer program that simulates human conversation through text or voice interactions. Chatbots are increasingly used in applications such as customer service, marketing, and education. They can be used to answer simple questions, provide customer support, and even interact with other applications.
In this tutorial, we will learn how to create an AI chatbot in Python using the Natural Language Toolkit (NLTK) library. NLTK is a leading platform for building Python programs to work with human language data.
What is Lemmatization?
Lemmatization is the process of grouping together the inflected forms of a word so they can be analysed as a single item. It is quite similar to stemming, with the only difference that lemmatization looks beyond word reduction, and considers a language’s full vocabulary to apply a morphological analysis to words. This results in the lemma of the word which is the dictionary form of the word, and typically the base form of the word.
How to Create AI Chatbot In Python Using NLP (NLTK)
Step 1 – import lemmatizer function
Import necessary lemmatizer from nltk.stem wordnet lemmatizer.
Step 2 – find stem root words
Define an example_sentence for finding stem root words by lemmatizer.
output:-
Step 3. Initialize WordnetLemmatizer() function.
Find stem root words in filter sentence words
Note: In the above output, you must be wondering why no actual root form has been given for any word, this is because they are given without context. You need to provide the context in which you want to lemmatize which is the parts-of-speech (POS). This is done by giving the value for pos parameter in wordnet_lemmatizer.lemmatize.
Output:-
Applications of Stemming and Lemmatization:
Stemming and Lemmatization are themselves forms of NLP and widely used for:
Text Classification: Stemming and lemmatization help to reduce the size of the feature space and so, speed up the process of text classification.
Information Retrieval: Stemming and lemmatization are used for efficient information retrieval in search engines and other applications.
Natural Language Processing: Stemming and lemmatization are used for natural language processing tasks such as part-of-speech tagging, parsing, and machine translation.
Spell Checking: Stemming and lemmatization are used for spell checking and other related tasks.
POS(Part of Speech)
POS stands for Part of Speech. It is a category of words that are defined according to their syntactic functions in a sentence. There are eight main parts of speech: nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections. Every word in a sentence is associated with grammar relations and a part of speech (pos) tag (nouns, verbs, adjectives, adverbs etc).
Part of speech tags are labels assigned to words in a sentence for the purpose of indicating the part of speech of the word. Common tags include noun, verb, adjective, adverb, pronoun, preposition, conjunction, and interjection.
Step 5. Import POS tags from nltk. Also, initialize POS tags.
Step 6. Define a sample string for tokenization and give POS tags to each word.
CC coordinating conjunction
CD cardinal digit
DT determiner
EX existential there (like: “there is” … think of it like “there exists”)
FW foreign word
IN preposition/subordinating conjunction
JJ adjective ‘big’
JJR adjective, comparative ‘bigger’
JJS adjective, superlative ‘biggest’
LS list marker 1)
MD modal could, will
NN noun, singular ‘desk’
NNS noun plural ‘desks’
NNP proper noun, singular ‘Harrison’
NNPS proper noun, plural ‘Americans’
PDT predeterminer ‘all the kids’
POS possessive ending parent’s
PRP personal pronoun I, he, she
PRP$ possessive pronoun my, his, hers
RB adverb very, silently,
RBR adverb, comparative better
RBS adverb, superlative best
RP particle give up
TO, to go ‘to’ the store.
UH interjection, errrrrrrrm
VB verb, base form take
VBD verb, past tense took
VBG verb, gerund/present participle taking
VBN verb, past participle taken
VBP verb, sing. present, non-3d take
VBZ verb, 3rd person sing. present takes
WDT wh-determiner which
WP wh-pronoun who, what
WP$ possessive wh-pronoun whose
WRB wh-adverb where, when
Output:-
Conclusion:-
With this, you have successfully created an AI Chatbot in Python using NLTK. Your chatbot is now ready to interact with users and engage in natural conversations.

Coding is generally considered a boring activity. After all, who wants to sit in front of a computer all day writing in a language that can’t even be read? But that is not all there is to code. It can be used for some really fun coding facts stuff, and there is so much amazing work that you can do only if you knew how to code.
5 Coding Facts That Blow Your Mind
Let us look at five great fun coding facts you might not know about coding.
You Can Make Games With Code
Coding is an umbrella term for the scores of languages and their versions that programmers use to make their applications. We have all played games, on consoles, our mobile phones, or our desktop computers and laptops, at some point in our life. It might not surprise you to know that these games are also created using code. The complex physics of the characters in these games, the design of the environment of the games, and each minute movement in the games have a piece of code behind them.
Game designers typically write in languages such as C++, C#, and Java. These are also some of the most popular kids coding languages, especially for children who like gaming. Coding courses are available widely in all of these languages and the broad domain of game design.
You Do Better At School If You Code
Making games and indulging in the fun applications of coding is all fine, but coding can have great advantages at school as well. Once you start taking classes that teach coding for kids, you will realize that coding requires a lot of brainpower as well. Coding even for the most fun tasks requires you to think quite a bit, and this sharpens your mind and increases your capability to think logically.
This logical capability can be of a lot of use to you at school. Especially in subjects like mathematics, you might find yourself topping the class simply because of the practice you got during coding! In fact, coding and mathematics have a kind of symbiotic relationship – what you learn in maths comes of use in code and vice versa.
You Can Follow Your Interest Using Coding
Regardless of what your favorite subject is, or what fields you are interested in, you will find a use for code everywhere. Be it through developing software, creating an all-new app, making a game, or building a simple utility, you will find that coding facts can be a way to enable you to follow your interests through a different path.
All subjects from science to social studies and from mathematics to philosophy use coding in some way for research or education. Be it sports or music, art or architecture, utilities that are made using code are prevalent in every field that you can think of. Taking simple online coding courses can qualify you and build your interest in creating such utilities.
You Can Predict Future Events Through Code
Did you know that predicting the future is an application of coding! Predictive modeling is a field of programming in which code is used to try and predict what will happen in the future on the basis of events that took place in the past. It uses concepts of artificial intelligence and machine learning to create algorithms that learn the behavior of past data and determine the course of future data.
Predictive modeling is one of the most futuristic applications of code and is used to determine everything from the next movie you will like on Netflix to whether it will rain tomorrow. You can opt for closing classes in machine learning to know more about the field, and create your own utilities to predict the future!
Coding Is Free!
You don’t need any sophisticated apparatus except your laptop for coding. All you need is the will to learn more and follow your interests through code. To learn to code you do not need to go to a special school or have any special capabilities. You can opt for free coding classes for kids which are held completely online and follow a completely hands-off approach in helping kids learn to code. There are also a vast number of coding sites for kids on which they can log in to learn basic coding facts for kids without even having to enroll in a class.
Conclusion
The future is already being written, and it is being written in code. Coding for kids classes can help kids of all ages currently going to school not just learn to code but also to have fun in the process. The above applications of code can be a major stepping stone to build the interest of kids in coding, after which they can hone their interests and new skills on even more advanced applications. A platform such as Learningbix can be an excellent way for you to get started.
