In this paper, the latent semantic indexing (LSI) based method was used to the various image feature extracted matrix in order to perform content-based image retrieval. The feature extraction techniques include color histogram, color auto-gram, color moment, gray-scale, and wavelet moment. The implementation of LSI here is to achieve an improved image retrieval performance, because it reduces t...

Latent Semantic Indexing (LSI), a variant of classical Vector Space Model (VSM), is an Information Retrieval (IR) model that attempts to capture the latent semantic relationship between the data items. Mathematical lattices, under the framework of Formal Concept Analysis (FCA), represent conceptual hierarchies in data and retrieve the information. However, both LSI and FCA use the data represen...

We have analyzed the image formation and dynamic properties in laser speckle imaging (LSI) both experimentally and with Monte Carlo simulation. We show for the case of a liquid inclusion that the spatial resolution and the signal itself are both significantly affected by scattering from the turbid environment. Multiple scattering leads to blurring of the dynamic inhomogeneity as detected by LSI...

In this paper we describe linguistic models and methods, which are being developed for semi{ automatic exploitation and enriching of a large and comprehensive (existing) corpus of English mathematical key{phrases. The starting point is the need for enhanced comparison of key{phrases, meaning, among others, abstraction over intersectivity and movement of modiiers, resolution of prepositional phr...

MOTIVATION A major challenge in the interpretation of high-throughput genomic data is understanding the functional associations between genes. Previously, several approaches have been described to extract gene relationships from various biological databases using term-matching methods. However, more flexible automated methods are needed to identify functional relationships (both explicit and im...

Due to the growth of large data collections, information retrieval or database searching is of vital importance. Lexical matching techniques may retrieve irrelevant or inaccurate results because of synonyms and polysemous words, so effective concept-based techniques are needed. One such technique is latent semantic indexing (LSI) which uses a vector-space approach by identifying documents whose...
