Google (GOOGL  ) is adding new features to its search engine, including smart videos that are relevant to user searches, an activity card, and a personalized "collections" facet.

"Featured Videos," or "smart videos," will return video search results that only show the short parts of videos that are relevant to your search. Google is also using artificial intelligence to "intelligently construct" Accelerated Mobile Pages (AMP) Stories - an interactive, visually rich, mobile-focused format for content. These new AMP stories appear in knowledge panels in search results for actors, athletes, musicians, and other famous people.

Google said on Monday, "Starting today with stories about notable people - like celebrities and athletes - providing a glimpse into facts and important moments from their lives in a rich, visual format. This format lets you easily tap to the articles for more information and provides a new way to discover content from the web."

Google is also introducing an activity card that will show up at the top of search results. It will show pages you've visited, as well as your queries about the certain area, Google vice president of product management Nick Fox said. One can delete items right from this activity card.The tech behemoth is also introducing something called "Collections." A person will be able to save content from the activity card to their collections. Google will then use things saved, and your history, in order to recommend new content for the collections.

The site's primary feed will now be called "Discover," and it will show videos, among other things, for the first time. When you search for an interest - hiking, let's say - at the top of Google search results you'll see a way to add hiking to the existing list of interests, and then content about the relevant subject will appear in your feed, said Emily Moxley, director of product for search. Google is bringing the Discover feed to the Google homepage on all mobile browsers in the next few weeks, according to Moxley.

The company is consistently thinking about new ways to upgrade and improve its search engine. Last year it ran more than 200,000 experiments for its search engine and initiated 2,500 changes to it, Google vice president of search Ben Gomes said at the event.

However, the AMP stories are a probably the feature that has got people most excited. "We've been able to do this in part thanks to advancements in computer vision, which help[s] us extract concepts from images," explained Cathy Edwards, director of engineering for Google Images, in a blog post Monday. "We model hundreds of millions of fine-grained concepts for every image and video that we have in our index. For example, an image of a tiger might generate concepts like 'feline,' 'animal' or 'big cat.' This lets us identify a picture by looking at its pixels, without needing to be told by the words on a page."
