Exercise

Semantic similarity for categorizing text

The main objective of semantic similarity is to measure the distance between the semantic meanings of a pair of words, phrases, sentences, or documents. For example, the word “car” is more similar to “bus” than it is to “cat”. In this exercise, you will find similar sentences to the word sauce from an example text in Amazon Fine Food Reviews. You can use spacy to calculate the similarity score of the word sauce and any of the sentences in a given texts string and report the most similar sentence's score.

A texts string is pre-loaded that contains all reviews' Text data. You'll use en_core_web_md English model for this exercise which is already available as nlp.
