Elasticsearch at Yelp Yelp’s web servers log data from the millions of sessions that our users initiate with Yelp every day. Our engineering teams can learn a lot from this data and use it to help monitor many critical systems. If you know what you’re looking for, archiving log files and retrieving them manually might be sufficient, but this process is tedious. As your infrastructure scales, so does the volume of log files, and the need for a log management system becomes apparent. Having already used it very successfully for other purposes, we decided to use Elasticsearch for indexing our...

You can search directly for a category near your current location, or open up the app directly to search input. App Extensions Today Widgets are a type of app extension (which include action, share, and photo editing extensions, custom keyboards, and document pickers). An app extension is a separate binary from the...

Since the dawn of time – or a very long time at least – the Yelp Android app has relied on a springboard design pattern for its navigation. This once-popular pattern served us well through the years as it allowed users quick access to Yelp’s most-used features. However, the design came with a series of trade-offs. The Yelp Android app back in 2009 and 2011 Navigating Yelp is inherently a free-form action. Users may search for a business, look through some of that business’ reviews, then check Talk for the latest news in their community, before finally liking some of...

At Yelp, we use categories for businesses to help determine search results, improve search relevance, inform our users of what a business does, as well as help our sales team target groups of businesses. For example, Starbucks is categorized as Coffee & Tea, and Walgreens stores are often categorized as both Drugstores and Convenience Stores.   A number of our businesses don’t have categories, but they do hold other clues which can be used to infer categories. They tend to be businesses with relatively few reviews and photos, since more popular businesses would have eventually been assigned a category by...

6. An impressive number. It’s 1 x 2 x 3 AND 1 + 2 + 3. It’s brilliant AND the number of degrees of freedom a rigid object has to move in three dimensions. It’s where we are in the history of the Yelp Academic Dataset challenge. We’ve had 5 rounds, hundreds of academic papers written, and we are excited to go at it again. Our dataset for this iteration includes information about local businesses in 10 cities across 4 countries. This dataset contains 1.6M reviews and 500K tips by 366K users for 61K businesses. It also comes with rich...

Most of July was spent ramping up for our internal hackathon so it was a little slower for us. Last month, we hosted a small PyLadies workshop and celebrated the Designers + Geeks 4 year anniversary (2.5 years of which have been hosted at Yelp!). We also had Tera- Nicholle Nelson, the VP of Marketing for MyFitnessPal and Under Armour, stop by our office to discuss how to “disrupt” yourself. Since hackathon recently wrapped up, we’re slowly recovering from dinosaurs, hacking, and our food comas (look out for our official hackathon post coming out soon!). Coming up this month, we’ve...
