Similarity search for web services

by Xin Dong, Alon Halevy, Jayant Madhavan, Ema Nemes, Jun Zhang - In Proc. of VLDB , 2004
"... Web services are loosely coupled software components, published, located, and invoked across the web. The growing number of web services available within an organization and on the Web raises a new and challenging search problem: locating desired web services. Traditional keyword search is insuffici ..."

A Simple Algorithm for Nearest Neighbor Search in High Dimensions

by Sameer A. Nene, Shree K. Nayar - IEEE Transactions on Pattern Analysis and Machine Intelligence , 1997
"... Abstract—The problem of finding the closest point in high-dimensional spaces is common in pattern recognition. Unfortunately, the complexity of most existing search algorithms, such as k-d tree and R-tree, grows exponentially with dimension, making them impractical for dimensionality above 15. In ne ..."

. Object recognition is demonstrated as an example application. The simplicity of the algorithm makes it possible to construct an inexpensive hardware search engine which can be 100 times faster than its software equivalent. A C++ implementation of our algorithm is available upon request to search@cs.columbia.edu/CAVE/.
