Abstract

Similarity query finds all the objects in the database that are similar to the query object according to a given similarity/distance function and a threshold. It plays a fundamental role in many areas such as data integration, pattern recognition, and biological or chemical informatics.

The talk will give an overview of our work in the area of similarity query processing, with an focus on some recent progress in error-tolerent autocompletion and c-approximate nearest neighbor search in high dimensional space.
