Whether you're new to NLP or looking to build foundational skills, this course provides a clear and practical path into one of the most exciting areas of AI and data science.
Through guided lessons and real-world examples, you'll learn how to clean, structure, and analyze text data, apply feature extraction techniques, and build basic NLP models for tasks like text classification and named entity recognition.
By the end of this course, you will be able to:
• Understand NLP basics and key language concepts like morphology, syntax, semantics, and pragmatics.
• Apply text cleaning and preprocessing techniques using NLTK and SpaCy, including tokenization, stemming, lemmatization, and embeddings.

NLP (Natural Language Processing) is a branch of artificial intelligence designed to help computers understand, interpret, and generate human language. It is an extensive field with many applications, such as machine translation, chatbots, text analysis, and sentiment analysis.
What are the key components of NLP?
The key components of NLP are:
Natural Language Understanding (NLU): The process of mapping human language input to a representation that can be understood by the computer.
Natural Language Generation (NLG): The process of generating human language output from a representation that can be understood by the computer.
What are some common applications of NLP?
Some common applications of NLP are:
Machine Translation: The process of translating text from one language to another.
Chatbots: Interactive systems that can communicate with users in natural language.
Text Analysis: The process of extracting information and insights from text data.
Sentiment analysis: Determining the emotional tone of text.
Question Answering: The development of systems that are capable of responding to inquiries regarding a specific text or knowledge base.
What are some challenges in NLP?
Some common challenges in NLP include:
Ambiguity: Words and phrases can have multiple meanings, making it difficult for computers to understand the intended meaning.
Context: The meaning of words and phrases can vary depending on the context in which they are used.
Computational Complexity: Processing large amounts of text data can be computationally expensive.
Bias: NLP models can reflect the biases present in the data they are trained on.
What problems does NLP solve?
Sentiment analysis, language translation, and named entity recognition are just a few examples of tasks classified as NLP problems. To enhance NLP solutions and applications, identifying these examples is crucial.
Does ChatGPT use NLP?
Indeed, ChatGPT implements natural language processing (NLP). In reality, NLP is a fundamental technology that enables ChatGPT to comprehend, generate, and respond to human language in a meaningful manner.
When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
