This course offers a clear pathway to undertsand advanced tokenization and sentiment analysis—two core pillars of modern NLP. You'll learn how to convert raw text into structured input using subword, character-level, and adaptive tokenization techniques, and how to extract sentiment using rule-based, statistical, and deep learning models.

Through hands-on exercises, you’ll gain the skills to handle complex language input, model sentiment at fine granularity, and deploy systems that generalize across domains and languages. By the end of this course, you will be able to: - Explain and apply advanced tokenization techniques, including BPE, character-level, and streaming methods - Handle out-of-vocabulary terms and domain-specific language using adaptive and hybrid encoding strategies - Build sentiment analysis models using VADER, Naïve Bayes, BERT, and RoBERTa - Address challenges such as class imbalance, multilingual variation, and aspect-level sentiment - Evaluate sentiment systems using semantic similarity, temporal trends, and domain-specific metrics This course is ideal for NLP practitioners, data scientists, developers, and applied researchers aiming to build robust, ethical, and production-ready sentiment analysis systems. A basic understanding of Python, NLP fundamentals, and machine learning is recommended. Join us to learn how tokenization and sentiment analysis power the next generation of intelligent language technologies.

In this module, learners will explore advanced techniques for breaking down and encoding text for machine understanding. They will examine subword, byte-level, and adaptive tokenization methods used in modern NLP models. The module also introduces character-level and hybrid embeddings, as well as sentence embeddings for capturing semantic meaning in tasks like search, classification, and clustering.

Frequently asked questions

This course provides a deep dive into modern tokenization strategies and sentiment analysis techniques used in multilingual and domain-specific NLP tasks. It explores subword modeling methods like Byte-Pair Encoding (BPE), WordPiece, and SentencePiece, and examines character-level encoding approaches. Learners work with cross-lingual embeddings such as MUSE and LASER, and fine-tune models like mBERT and XLM-R for sentiment classification. The course also covers Aspect-Based Sentiment Analysis (ABSA), lexicon-based methods using VADER and SentiWordNet, and applies these techniques to real-world use cases like social media monitoring, political discourse analysis, and crisis event sentiment tracking.

Learners explore modern tokenization strategies, including Byte-Pair Encoding (BPE), WordPiece, SentencePiece, and character-level encoding, all crucial for subword-level text representation.

Yes. The course emphasizes multilingual and cross-lingual sentiment analysis, using shared subword vocabularies and models like mBERT and XLM-R to handle multiple languages effectively.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

The course may not offer an audit option. 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.

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. If you only want to read and view the course content, you can audit the course for free.
