An index-based algorithm for fast on-line query processing of latent semantic analysis. [PDF]
PLoS ONE, 2017 Latent Semantic Analysis (LSA) is widely used for finding the documents whose semantic is similar to the query of keywords. Although LSA yield promising similar results, the existing LSA algorithms involve lots of unnecessary operations in similarity ...

Complex Spatial Query Processing [PDF]
GeoInformatica, 2004 The user of a Geographical Information System is not limited to conventional spatial selections and joins, but may also pose more complicated and descriptive queries. In this paper, we focus on the efficient processing and optimization of complex spatial queries that involve combinations of spatial selections and joins. Our contribution is manifold; we
