Latent Semantic Indexing is a novel information retrieval model that will become more and more valuable as the amount of electronic information increases. It has been used effectively in a variety of applications, including information filtering [9] and cross-language information retrieval [25]. With the recent explosion in the amount of information available on the World-Wide Web, the advent of electronic commerce, and the ability of LSI to find information similar to (rather than literally matching) other information, LSI has the potential to become the information retrieval method of choice by those who desire an alternative to keyword searching.
LSI++ is an efficient, flexible, and extensible implementation of LSI. Its object-oriented design makes it easy to maintain and modify. In addition, the LSI++ Application Programming Interface allows it to be used in a variety of applications without modification. The LSI++ WWW interface provides a highly-portable, simple, and powerful interface to the LSI++ search engine. It completely hides the details of the LSI model, allowing even a naive user the ability to harness the full power of LSI. Coupled with the high performance of LSI++, the LSI++ WWW interface can provide access to a large amount of information quickly and intuitively.
