The Aho-Corasick algorithm can be used to efficiently search for multiple patterns in a large blob of text, making it a really useful algorithm in data science and many other areas.

In this article, Toptal Freelance Software Engineer Roman Vashchegin shows how the Aho-Corasick algorithm uses a trie data structure to efficiently match a dictionary of words against any text.
