Do you remember the last time you spoke to a customer service associate on call or via chat for an incorrect item delivered to you from Amazon, Flipkart, or Walmart? Most likely you would have had a conversation with a chatbot instead of a customer service agent. Gartner estimates that 85% of customer interactions will be handled by chatbots by 2021. So what exactly is a chatbot? How can you build an intelligent chatbot using Python?
A chatbot is an AI-based digital assistant that can understand human capabilities and simulate human conversations in natural language to give prompt answers to their questions just like a real human would. Chatbots help businesses increase their operational efficiency by automating customer requests.
The most important task of a chatbot is to analyze and understand the intent of a customer request to extract relevant entities. The bot then delivers an appropriate response to the user based on the analysis. Natural language processing plays a vital role in text analytics through chatbots making the interaction between the computer and human feel like a real human conversation. Every chatbot works by adopting the following three classification methods-
In this data science project, you will use a leading and powerful Python library NLTK (Natural Language Toolkit) to work with text data.
Are you excited to build a chatbot of your own? Build a conversational chatbot using Python from Scratch that understands what a customer is talking about and responds appropriately.
According to EuropeanBusinessReview, telecommunication providers lose close to $65 million a month from customer churn. Isn’t that expensive? With many emerging telecom giants, the competition in the telecom sector is increasing and the chances of customers discontinuing a service are high. This is often referred to as Customer Churn in Telecom. Telecommunication providers that focus on quality service, lower-cost subscription plans, availability of content and features whilst creating positive customer service experiences have high chances of customer retention. The good news is that all these factors can be measured with different layers of data about billing history, subscription plans, cost of content, network/bandwidth utilization, and more to get a 360-degree view of the customer. This 360-degree view of customer data can be leveraged for predictive analytics to identify patterns and various trends that influence customer satisfaction and help reduce churn in telecom.
Considering that customer churn in telecom is expensive and inevitable, leveraging analytics to understand the factors that influence customer attrition, identifying customers that are most likely to churn, and offering them discounts can be a great way to reduce it. In this data science project, you will build a logistic regression machine learning model to understand the correlation between the different variables in the dataset and customer churn. This end-to-end churn prediction machine learning model using R will tweak the problem of unsatisfied customers and make the revenue flowing for the telecom company.

Gone are the days when recruiters used to manually screen resumes for a long time. Sifting through thousands of candidates’ resumes for a job is no more a challenging task- all thanks to resume parsers. Resume parsers use machine learning technology to help recruiters search thousands of resumes in an intelligent manner so they can screen the right candidate for a job interview.
A resume parser or a CV parser is a program that analyses and extracts CV/ Resume data according to the job description and returns machine-readable output that is suitable for storage, manipulation, and reporting by a computer. A resume parser stores the extracted information for each resume with a unique entry thereby helping recruiters get a list of relevant candidates for a specific search of keywords and phrases (skills). Resume parsers help recruiters set a specific criterion for a job, and candidate resumes that do not match the set criteria are filtered out automatically.
In this data science project, you will build an NLP algorithm that parses a resume and looks for the words (skills) mentioned in the job description. You will use the Phrase Matcher feature of the NLP library Spacy that does “word/phrase” matching for the resume documents. The resume parser then counts the occurrence of words (skills) under various categories for each resume that helps recruiters screen ideal candidates for a job.
