Hypersphere Indexer

Indexing high-dimensional data for efficient nearest-neighbor searches poses interesting research challenges. It is well known that when data dimension is high, the search time can exceed the time required for performing a linear scan on the entire dataset. To alleviate this dimensionality curse, indexing schemes such as locality sensitive hashing (LSH) and M-trees were proposed to perform appr...

Political News Indexer

In and around Washington D.C. today, one of the hottest buzzwords flying around is “digital government.” Millions of people are logging on to the web every day to get informed about, and get involved in the political process. They can register to vote, fill out their tax forms, join a grassroots campaign, donate money to political causes, read the news, read opinions, and voice their own for ev...

DNA sequencing by indexer walking.

BACKGROUND There is a need for DNA sequencing methods that are faster, more accurate, and less expensive than existing techniques. Here we present a new method for DNA analysis by means of indexer walking. METHODS For DNA sequencing by indexer walking, we ligated double-stranded synthetic oligonucleotides (indexers) to DNA fragments that were produced by type IIS restriction endonucleases, wh...

WINGS: A Parallel Indexer for Web Contents

In this paper we discuss the design of a parallel indexer for Web documents. By exploiting both data and pipeline parallelism, our prototype indexer efficiently builds a partitioned inverted compressed index, a suitable data structure commonly utilized by modern Web Search Engines. We discuss implementation issues and report the results of preliminary tests conducted on a SMP PCs.
