Reliable and Reproducible Evaluation of High-Dimensional Index Structures (QuEval)
Multimedia data, or high-dimensional data in general, have been subject to research for more than two decades and gain momentum even more in the communication technology age. From a database point of view, the myriads of gigabyte of data pose the problem of managing these data. In this course, query processing is a challenging task due to the high dimensionality of such data. In the past, dozens of index structures for high-dimensional data have been proposed and some of them are even standard-like references. However, it is still some kind of black magic to decide which index structure fits to a certain problem or outweighs other index structures.

QuEval
This is where QuEval, a framework for quantitative comparison and evaluation of high-dimensional index structures comes into play. QuEval is a Java-based framework that supports the comparison of index strucutres regarding certain characteristics such as dimensionality, accuracy, or performance. Currently, the framework contains six different index structures. However, a main focus of the framework is its extensibility and we encourage people to contribute to QuEval by providing more index structures or other interesting aspects for their comparison.
