我們研究關於Latent Semantic Indexing 系統,並提供兩個方法與此系統做比較。
In this article we study the well-known information
retrieval(IR) system : the Latent Semantic Indexing(LSI) model. This method
projects document vectors into some specific subspace of the range of the
term-document matrix. We provide two new methods, called QR method and
Gram-Schmidt method, for projecting document vectors into different subspaces
and compare them with the LSI model. Furthermore, we show the numerical
experiment in using the LSI model, the vector space model, and the QR method
on Medline collection and Cranfield collection.
