There is an arms race to perform increasingly sophisticated data analysis on ever more varied types of data (text, audio, video, OCR, sensor data, etc.). Current data processing systems typically assume that the data have rigid, precise semantics, which these new data sources do not possess. On the other hand, many of the state-of-the-art approaches to both cope with variations in the structure of data and to deeply anlayze data are statistical. The Hazy project is exploring integrating statistical processing techniques with data processing systems with the goal of making such systems easier to build, to deploy, and to maintain.

The key technical hypothesis behind Hazy is that a large fraction of the processing performed by applications that use and analyze these new sources of data can be captured using a small handful of primitives. Identifying this small handful of primitives is one of Hazy's chief goals.

To understand this hypothesis, Professor Re's group is building several applications, including a system to read large amounts of text and answer sophisticated questions (see WiscI and GeoDeepDive) and a system to help find Neutrinos (see IceCube), along with building general primitives for data analytics.
