Event Details

It’s in your browser. Your operating system. Your phone. Your car. Your automated home assistant. And of course, it’s on your institution's public website.

Search is everywhere.

But most users, and even most administrators or engineers, know very little about what happens behind the scenes when you type something into that proverbial textbox.

In this talk we’ll take a deep dive to understand how Search works from the ground up. We’ll cover classic information retrieval subjects like:

  • Inverted Index

  • Analysis

  • Tokenization

  • Character Normalization

  • Stemming / Lemmatization

  • Stopwords

  • Synonyms

  • Ranking

  • TFIDF/BM25


We’ll also briefly talk about the components that make modern search engines like Google orders of magnitude more intelligent and resilient than these classic technique
