The conventional indexing technique designed for the traditional database systems does not use the read-only characteristics of the data warehouse environment. Recently, Bitmap Indexing has been proposed as a candidate indexing structure suitable for the read-only environments, like those of decision support systems. The current paper presents a short literature survey of the various clone of t...

In large content-based image database applications, e cient information retrieval depends heavily on good indexing structures of the extracted features. While indexing techniques for text retrieval are well understood, e cient and robust indexing methodology for image retrieval is still in its infancy. In this paper, we present a non-hierarchical clustering scheme for index generation using the...

-Markovsemantic indexing algorithm based on the controlled Markov chain modeling framework. Controlled Markov chain models are used to describe the temporal evolution of low-level visual descriptors extracted from the semantic indexing model. Propose a semantic indexing algorithm which uses both text and image retrieval system.The entire user Queries selected by randomly. An image retrieval sys...

DEFINITION Multimedia (MM) data indexing refers to the problem of preprocessing a database of MM objects so that they can be efficiently searched for on the basis of their content. Due to the very nature of MM data, indexing solutions are needed to efficiently support similarity queries, where the similarity of two objects is usually defined by some expert of the domain and can vary depending o...

the aim of this study was comparative evaluation of iran scientific output in the field of food science and technology with five countries including ireland, turkey, egypt, argentina and malaysia during 1990-2010 in the web of science. the number of indexing scientific outputs in this database show that ireland, argentina and turkey ranked sequentially. articles have the largest share of scient...

This thesis focuses on the problem of fast sub-structure search and remote homology detection in proteins by finding similar (sub)structures. That is, for a given query protein and a large database of protein structures, we want to retrieve all the similar structures from the database rapidly. With the growing number of proteins deposited in the database, searching the database is a difficult a...

Fast retrieval using organ shapes is crucial in medical image databases since shape is a clinically prominent feature. In this paper, we propose that 2-D shapes in medical image databases can be indexed by embedding them into a vector space and using efficient vector space indexing. An optimal shape space embedding is proposed for this purpose. Experimental results of indexing vertebral shapes ...

We introduce indexing of tables referencing complex structures such as digraphs and spatial objects, appearing in genetics and other data intensive analysis. The indexing is achieved by extracting dimension schemas from the referenced structures. The schemas and their dimensionality are determined by proper coloring algorithms and the duality between all such schemas and all such possible prope...

In this paper, we present our experience in indexing the dropoff and pick-up locations of taxi trips in New York City. The paper presents a comprehensive experimental analysis of classic and state-ofthe-art spatial database indexing schemes. The paper evaluates a popular spatial tree indexing scheme (i.e., GIST-Spatial), a Block Range Index (BRIN-Spatial) provided by PostgreSQL as well as a new...

The Common Indexing Protocol (CIP) is used to pass indexing information from server to server in order to facilitate query routing. Query routing is the process of redirecting and replicating queries through a distributed database system towards servers holding the desired results. This document describes the CIP framework, including its architecture and the protocol specifics of exchanging ind...
