Online retailers have taken steps during the pandemic to improve their search and recommendation engines by building predictive models with high levels of accuracy.
Gartner's Bob Hetu said online retailers increasingly are turning to computer vision models to index products in their virtual catalog using visual cues and natural-language processing to aggregate and learn from words used in shoppers' searches.
These tools rely on algorithms powered by machine learning, which continually use the results they produce to fine-tune the models.
Wayfair's computer-vision algorithm captures design features, materials, styles, color, vintage, and other elements to tag items, and the richer the list of keywords tagged to a product, the more relevant the search results.
Meanwhile, Etsy's search engine uses natural-language process to learn from customers' past queries and purchases, and the company plans to train algorithms to combine product and search data over time to gauge a shopper's overall taste.
