Python is one of the fastest growing programming languages. It has undergone more than 28 years of the successful span. Python itself reveals its success story and a promising future ahead. Python programming language is presently being used by a number of high traffic websites including Google, Yahoo Groups, Yahoo Maps, Shopzilla, Web Therapy, Facebook, NASA, Nokia, IBM, SGI Inc, Quora, Dropbox, Instagram and Youtube. Similarly, Python also discovers a countless use for creating gaming, financial, scientific and instructive applications.

 

Python is a fast, flexible, and powerful programing language that's freely available and used in many application domains. Python is known for its clear syntax, concise code, fast process, and cross-platform compatibility.

 

Python is considered to be in the first place in the list of all AI and machine learning development languages due to the simplicity. The syntaxes belonging to python are terribly easy and can be easily learn. Therefore, several AI algorithms will be easily implemented in it. Python takes short development time as compared to different languages like Java, C++ or Ruby. Python supports object oriented, functional as well as procedure oriented styles of programming. There are lots of libraries in python that make our tasks easier.

 

Some technologies relying on python:

Python has become the core language as far as the success of following technologies is concerned. Let’s dive into the technologies which use python as a core element for research, production and further developments.

 

  1. Networking: Networking is another field in which python has a brighter scope in the future. Python programming language is used to read, write and configure routers and switches and perform other networking automation tasks in a cost-effective and secure manner.
  2. Big Data: The future scope of python programming language can also be predicted by the way it has helped big data technology to grow. Python has been successfully contributing in analyzing a large number of data sets across computer clusters through its high-performance toolkits and libraries.
  3. Artificial Intelligence (AI): There are plenty of python frameworks, libraries, and tools that are specifically developed to direct Artificial Intelligence to reduce human efforts with increased accuracy and efficiency for various development purposes. It is only the Artificial Intelligence that has made it possible to develop speech recognition system, interpreting data like images, videos etc.

 

Why Choose Python for Artificial Intelligence and Machine Learning?

Whether a startup or associate MNC, Python provides a large list of benefits to all. The usage of Python is specified it cannot be restricted to only one activity. Its growing popularity has allowed it to enter into some of the most popular and complicated processes like artificial intelligence (AI), Machine Learning (ML), natural language process, data science etc. The question is why Python is gaining such momentum in AI? And therefore the answer lies below:

 

Flexibility: Flexibility is one of the core advantages of Python. With the option to choose between OOPs approach and scripting, Python is suitable for every purpose. It works as a perfect backend and it also suitable for linking different data structures together.

 

Platform agnostic: Python provides developer with the flexibility to provide an API from the existing programming language. Python is also platform independent, with just minor changes in the source codes, you can get your project or application up and running on different operating systems.

 

Support: Python is a completely open source with a great community. There is a host of resources available which can get any developer up to speed in no time. Not to forget, there is a huge community of active coders willing to help programmers in every stage of developing cycle.

 

Prebuilt Libraries: Python has a lot of libraries for every need of your AI project. Few names include Numpy for scientific computation, Scipy for advanced computing and Pybrain for machine learning.

 

Less Code: Python provides ease of testing - one of the best among competitors. Python helps in easy writing and execution of codes. Python can implement the same logic with as much as 1/5th code as compared to other OOPs languages.

 

Applications of Python:

There are so many applications of Python in the real world. But over time we’ve seen that there are three main applications for Python

Web Development: Web frameworks that are based on Python like Django and Flask have recently become very popular for web development.

Data Science (including Machine Learning): Machine Learning with Python has made it possible to recognize images, videos, speech recognition and much more.

Data Analysis/Visualization: Python is also better for data manipulation and repeated tasks. Python helps in the analysis of a large amount of data through its high-performance libraries and tools. One of the most popular Python libraries for the data visualization is Matplotlib.

 

A chatbot is an artificial intelligence powered piece of software in a device, application, web site or alternative networks that try to complete consumer’s needs and then assist them to perform a selected task. Now a days almost every company has a chatbot deployed to interact with the users.

 

Chatbots are often used in many departments, businesses and every environment. They are artificial narrow intelligence (ANI). Chatbots only do a restricted quantity of task i.e. as per their design. However, these Chatbots make our lives easier and convenient. The trend of Chatbots is growing rapidly between businesses and entrepreneurs, and are willing to bring chatbots to their sites. You might also produce it yourself using Python.

 

How do chatbots work?

There are broadly two variants of chatbotsRule-Based and Self learning.

  1. In a Rule-based approach, a bot answers questions based on some rules on that it is trained on. The rules outlined could be very easy to very complicated. The bots will handle easy queries but fail to manage complicated ones.
  2. The Self learning bots are those that use some Machine Learning-based approaches and are positively a lot of economical than rule-based bots. These bots may be of additional two types: Retrieval based or Generative.
    1. In retrieval-based models, Chatbot uses the message and context of conversation for selecting the best response from a predefined list of bot messages.
    2. Generative bots can generate the answers and not always reply with one of the answers from a set of answers. This makes them more intelligent as they take word by word from the query and generates the answers.

 

Building a chatbot using Python

NLP:

The field of study that focuses on the interactions between human language and computers is called Natural Language Processing. NLP is a way for computers to analyze, understand, and derive meaning from human language in a smart and useful way. However, if you are new to NLP, you can read Natural Language Processing in Python.

 

NLTK:

NLTK (Natural Language Toolkit) is a leading platform for building Python programs to work with human language data. It provides easy-to-use lexical resources such as WordNet, along with a suite of text processing libraries.

 

Importing necessary libraries

import nltk 

import numpy as np 

import random 

import string # to process standard python strings

 

Copy the content in text file named ‘chatbot.txt’, read in the text file and convert the entire file content into a list of sentences and a list of words for further pre-processing.

 

f=open('chatbot.txt','r',errors = 'ignore')

raw=f.read()

raw=raw.lower()# converts to lowercase

nltk.download('punkt') # first-time use only

nltk.download('wordnet') # first-time use only

sent_tokens = nltk.sent_tokenize(raw)# converts to list of sentences 

word_tokens = nltk.word_tokenize(raw)# converts to list of words

 

Pre-processing the raw text

We shall now define a function called LemTokens which will take as input the tokens and return normalized tokens.

 

lemmer = nltk.stem.WordNetLemmatizer()

#WordNet is a semantically-oriented dictionary of English included in NLTK.

def LemTokens(tokens):     

return [lemmer.lemmatize(token) for token in tokens]

remove_punct_dict = dict((ord(punct), None) for punct in string.punctuation) 

def LemNormalize(text):     

return LemTokens(nltk.word_tokenize(text.lower().translate(remove_punct_dict)))

 

Keyword matching

Define a function for greeting by bot i.e. if user’s input is greeting, the bot shall return a greeting response.

GREETING_INPUTS = ("hello", "hi", "greetings", "sup", "what's up","hey",)

GREETING_RESPONSES = ["hi", "hey", "*nods*", "hi there", "hello", "I am glad! You are talking to me"]

def greeting(sentence):

for word in sentence.split():

if word.lower() in GREETING_INPUTS:

return random.choice(GREETING_RESPONSES)

 

Generate responses

To generate a response from our bot for input queries, the concept of document similarity is used. Therefore, we start by importing necessary modules.

From scikit learn library, import the TFidf vector to convert a collection of raw documents to a matrix of TF-IDF features

from sklearn.feature_extraction.text import TfidfVectorizer

Also, import cosine similarity module from scikit learn library

from sklearn.metrics.pairwise import cosine_similarity

This will be used to find the similarity between words entered by the user and therefore the words within the corpus. This can be the simplest possible implementation of a chatbot.

Define a function response that searches the user’s vocalization for one or more known keywords and returns one of several possible responses. If it doesn’t find the input matching any of the keywords, it returns a response: “I’m sorry! I don’t understand you”

 

def response(user_response):

robo_response=''

sent_tokens.append(user_response)

TfidfVec = TfidfVectorizer(tokenizer=LemNormalize, stop_words='english')

tfidf = TfidfVec.fit_transform(sent_tokens)

vals = cosine_similarity(tfidf[-1], tfidf)

idx=vals.argsort()[0][-2]

flat = vals.flatten()

flat.sort()

req_tfidf = flat[-2]

if(req_tfidf==0):

robo_response=robo_response+"I am sorry! I don't understand you"

return robo_response

else:  robo_response = robo_response+sent_tokens[idx]

return robo_response

 

I have tried to explain in simple steps how you can build your own chatbot using NLTK and of course it’s not an intelligent one.

I hope you guys have enjoyed reading.

Happy Learning!!!

Picking the right company structure for your business is as important as any other business-related activity. The right business structure can allow your enterprise to control efficiently and meet your required business targets. In India, each business should register themselves as a part of the necessary legal compliance. Before we tend to learn how to register a company, let’s try and understand the types of business structures in India.

Types of business structure in India:

  1. One Person Company (OPC): It is the simplest way to start a company if there exists only 1 promoter or owner. It allows a sole-proprietor to hold on his work and still be a part of the company framework.
  2. Limited Liability Partnership (LLP): This kind of business structure was essentially formed to provide limited liability to its owners. To become a partner of LLP doesn’t involve a huge lengthy complicated method. It’s simple to form as well as simple to become a partner. In it, each partner has limited liability to the extent of capital contributed by them. They don’t have to suffer on behalf of its other partners.
  3. Private Limited Company: A Private Limited Company is that company which is owned privately by the individuals. It is more flexible and easy to form than a Public company. It can be formed with just 2 members and 2 directors. But there is a restriction in the maximum number of its partners which is restricted to 200. The number of shareholders is limited to 50 only. A Private company cannot invite public to apply for its shares. This kind of company is more preferred by investors because they can buy/sell stakes easily.
  4. Public Limited Company: A Public Limited Company is that company which is owned by public or in which the public can subscribe. The minimum number of directors is 3 and the minimum number of shareholders is 7. There is no limit on the maximum number of shareholders. The shareholders have limited liability to the extent of the face value of its shares and the premium respectively.

Steps for registration of new company

Obtain Director Identification Number

Director identification number is a unique number allotted by Central Government to any person assuming to be a director or existing director of company in India. Director identification number is 8 digit unique number which has a lifetime validity, details of director are maintained in database through this number.

Whenever a return, an application or any information associated with a corporation or company are going to be submitted under any law, the director signing such return, application or information will mention his Director Identification Number underneath his signature.

Procedure to obtain DIN: There are three different forms

1.      Spice Form (Application Of First Directors In Case Of New Companies): SPICe form is used by the first directors of new companies. The intended person who has not obtained DIN shall make an application through eForm SPICe. The documents which  need to be attached are

·         Proof of identity

·         Proof of address

2.      DIR-3 Form: Any person intending to become a director in an already existing company shall have to make an application in eForm DIR-3 for allotment of DIN.

·         Procedure to obtain DIR-3 Form: The form shall be mandatorily signed by the applicant and the same shall be verified digitally by a:

·   Company Secretary (who is fulltime employment of the company)

·   Managing director or manager.

·   Chief Executive Officer or Chief Financial Officer.

Two supporting documents need to be attached that is:

·   Photograph of the concerned applicant.

·   Proof of identity and Proof of residence.

3.      DIR-6 Form: DIR-6 Form is used by the directors when there are any changes in the particulars of the directors. The form shall be signed by the applicant and certified by a Chartered Accountant, Company Secretary, Cost accountant (whole time practice), Director of an existing company.

Obtain Digital Signature Certificate

A Digital Signature Certificate is a secure digital key that is issued by the certifying authorities for the purpose of validating and certifying the identity of the person holding this certificate. Digital Signatures make use of the general public key encryptions to create the signatures. A digital signature certificate (DSC) contains information concerning the user’s name, pin code, country, email address, date of issuance of certificate and name of the certifying authority.

A Digital Signature Certificate (DSC) explicitly associates the identity of an individual/device with a two keys - public and private keys. The certificate contains data about a user's identity (for example, their name, pincode, country, email address, the date the certificate was issued and also the name of the CA. These keys will not work in the absence of the other. They’re used by browsers and servers to encode and decode data concerning the identity of the certificate user.

The private key is stored on the user's computer hard disk or on an external device like a USB token. The user retains control of the private key; it will solely be used with the issued password. The public key is disseminated with the encrypted data. The authentication method fails if either one of these keys in not available or do not match. This means that the encrypted information cannot be decrypted and so, is inaccessible to unauthorized parties.

Procedure to obtain digital signature certificate

  1. Submission of DSC Application form duly filled in by the applicant. Any individual applying for a Digital Signature Certificate is required to fill an Application Form for online submission and verification of personal details by the certifying authority.
  2. Producing Photo ID proof
  3. Producing  Address proof
  4. To fill in the Application form the please log in to the website of the Certifying Authority.

Register a Company Name

Tips for naming your startup company:

  1. Avoid hard to spell, you don’t want potential customers getting confused concerning how to find your business on-line. You would like to avoid having to continually correct the misspelled version of your name. Keep it simple.
  2. Don’t pick a name that could be limiting as your business grows.
  3. Once you have determined a name you like, do a web search on the name. You will find that someone else is already using that business name.
  4. Use the most secure “.com” domain name for your business rather than alternatives such as .net, .org, .biz, or other possible domain extensions.
  5. You want the business name to convey something meaningful and positive related to your business.
  6. Make sure you are personally happy with the name.

To register your company, you will file your completed application online with the Indian government’s Registrar of Companies, or RoC. The RoC, which is under the jurisdiction of the Ministry of Corporate Affairs, oversees the incorporation of new companies and the administration of businesses under the statutory regulations of the Companies Act.

Check online to see if your choice of company name is available. Before you file your application to register your company, it’s a good idea to have your company names firmly in place to ensure the registration process isn’t hindered.

Get Certificate of Incorporation

A Certificate of Incorporation (COI) is a legal document that is issued by Ministry of Corporate Affairs (MCA) once a Company is successfully registered with them. The COI is a proof that the company is now registered with the Registrar of Companies (ROC).

COI issued consists of a date which depicts the date from which the company is deemed to be official registered. It can then commence its business and start working. Unlike sole proprietorship registration of private limited company is mandatory. It is the duty of the promoter to apply for a COI.

Obtain Permanent Account Number

Permanent Account number (PAN) refers to a ten-digit alphanumeric number, issued in the form of a laminated card, by the income tax Department in India. it is a must to have a PAN number for all those who file their income tax returns, because from 2005 onward, it has been made mandatory by the income tax Department to quote the PAN on return of income as well as on all correspondence with any income tax authority in the country.

Registration of GST

GST is the biggest tax reform in India, tremendously improving ease of doing business and increasing the taxpayer base in India by bringing in millions of small businesses in India. By abolishing and subsuming multiple taxes into a single system, tax complexities would be reduced while tax base is increased substantially. Under the new GST regime, all entities involved in buying or selling goods or providing services or both are required to register for GST. Entities without GST registration would not be allowed to collect GST from a customer or claim an input tax credit of GST paid and/or could be penalized. Further, registration under GST is mandatory once an entity crosses the minimum threshold turnover of starts a new business that is expected to cross the prescribed turnover.
