Abstract
Using current information retrieval system,
users expect more precise result like paragraphs,
lists, etc.. In order to solve the problem of
passage retrieval, a passage retrieval system is
implemented by using LSI (Latent Semantics
Indexing). At the same time the properties of LSI
under passage retrieval is investigated. These
properties includes optimal query length, optimal
word segmentation, optimal document
segmentation, impact when appending new
documents, and the benefit of relevance feed-back.
