Dataset Search launches publicly with an index of 25 million datasets, helping scientists, journalists, students, data geeks to find data.

What’s new in Dataset Search?
Based on what weve learned from the early adopters of Dataset Search, weve added new features. You can now filter the results based on the types of dataset that you want (e.g., tables, images, text), or whether the dataset is available for free from the provider. If a dataset is about a geographic area, you can see the map. Plus, the product is now available on mobile and weve significantly improved the quality of dataset descriptions. One thing hasn’t changed however: anybody who publishes data can make their datasets discoverable in Dataset Search by using an open standard (schema.org) to describe the properties of their dataset on their own web page.
We have also learned how many different types of people look for data. There are academic researchers, finding data to develop their hypotheses (e.g., try oxytocin), students looking for free data in a tabular format, covering the topic of their senior thesis (e.g., try incarceration rates with the corresponding filters), business analysts and data scientists looking for information on mobile apps or fast food establishments, and so on. There is data on all of that! And what do our users ask? The most common queries include “education,” “weather,” “cancer,” “crime,” “soccer,” and, yes, “dogs”.
