How Does Query Intent Classification Work?

So far our second season of Lucidworks has looked at NLP vs NLU, Learning to Rank, and the advent of neural IR search. This week, we’re jumping into query intent classification.

If I am shopping online for a shovel, there’s a big difference in my search results if I’m search for a garden shovel in the summer or a snow shovel in the winter.  How does the search engine know what I mean?

Older search systems would use a big long list of manually inputted rules and logic to decide that if it’s winter time then show the user snow shovels and if it’s summer then maybe a gardening trowel or sand bucket and shovel for the beach. But when you have thousands or millions of products this can get unwieldy fast.

what is query intent classification b

Query intent classification starts with a set of training data, which is a list of queries from users and important context like the user’s location and date it was when they clicked on a particular type of shovel. This data gets fed into your neural network for analysis and deep learning. Then the next time a similar user with a similar history and similar location starts a search, the system will automatically boost the intended results. This is one way neural networks help avoid hand-constructing rules, complex algorithms, potential human error, and overall headaches.
