NSF CAREER Award #1552538: "CAREER: FIREFLY - Rich Explanations for Database Queries"

Overview

The recent popularity of Big Data has inspired a range of users to seek high level explanations for trends and anomalies
in different applications. Such a user will typically run some queries on the datasets, compute some aggregates,
plot the answers as a graph, and look for explanations for what she observes: "Why are two graphs similar/different?"
"Why is a sequence of points increasing/decreasing?" "Why is there a sudden spike or dip in a graph" etc. The FireFly project
aims to introduce a fresh perspective to data analysis and help users understand query results with fast, rich, insightful explanations.
