While this tutorial won’t dive too deeply into feature selection and feature engineering, you’ll be able to see their effects on the accuracy of classifiers. Beyond Python’s own string manipulation methods, NLTK provides nltk.word_tokenize(), a function that splits raw text into individual words. While tokenization is itself a bigger topic (and likely one of the steps you’ll take when creating a custom corpus), this tokenizer delivers simple word lists really well.

This targeted approach to SEO can significantly boost website visibility, organic traffic, and conversion rates. In AI and machine learning, semantic analysis helps in feature extraction, sentiment analysis, and understanding relationships in data, which enhances the performance of models. If you’re interested in a career that involves semantic analysis, working as a natural language processing engineer is a good choice.

Remember that punctuation will be counted as individual words, so use str.isalpha() to filter them out later. While you’ll use corpora provided by NLTK for this tutorial, it’s possible to build your own text corpora from any source. Building a corpus can be as simple as loading some plain text or as complex as labeling and categorizing each sentence. Refer to NLTK’s documentation for more information on how to work with corpus readers. For Example, Tagging Twitter mentions by sentiment to get a sense of how customers feel about your product and can identify unhappy customers in real-time. The meaning representation can be used to reason for verifying what is correct in the world as well as to extract the knowledge with the help of semantic representation.

However, many organizations struggle to capitalize on it because of their inability to analyze unstructured data.
