Visual Information Seeking: Tight Coupling of Dynamic Query Filters with Starfield Displays

by Christopher Ahlberg, Ben Shneiderman , 1994
"... This paper offers new principles for visual information seeking (VIS). A key concept is to support browsing, which is distinguished from familiar query composition and information retrieval because of its emphasis on rapid filtering to reduce result sets, progressive refinement of search parameters, ..."

Data Mining: Concepts and Techniques

by Jiawei Han, Micheline Kamber , 2000
"... Our capabilities of both generating and collecting data have been increasing rapidly in the last several decades. Contributing factors include the widespread use of bar codes for most commercial products, the computerization of many business, scientific and government transactions and managements, a ..."

Kernel-Based Object Tracking

by Dorin Comaniciu, Visvanathan Ramesh, Peter Meer , 2003
"... A new approach toward target representation and localization, the central component in visual tracking of non-rigid objects, is proposed. The feature histogram based target representations are regularized by spatial masking with an isotropic kernel. The masking induces spatially-smooth similarity fu ..."

A survey on visual surveillance of object motion and behaviors

by Weiming Hu, Tieniu Tan, Liang Wang, Steve Maybank - IEEE Transactions on Systems, Man and Cybernetics , 2004
"... Abstract—Visual surveillance in dynamic scenes, especially for humans and vehicles, is currently one of the most active research topics in computer vision. It has a wide spectrum of promising applications, including access control in special areas, human identification at a distance, crowd flux stat ..."

TileBars: Visualization of Term Distribution Information in Full Text Information Access

by Marti A. Hearst , 1995
"... The field of information retrieval has traditionally focused on textbases consisting of titles and abstracts. As a consequence, many underlying assumptions must be altered for retrieval from full-length text collections. This paper argues for making use of text structure when retrieving from full te ..."

. The patterns in a column of TileBars can be quickly scanned and deciphered, aiding users in making judgments about the potential relevance of the retrieved documents. KEYWORDS: Information retrieval, Full-length text, Visualization. INTRODUCTION Information access systems have traditionally focused

Visual Information Retrieval

by Amarnath Gupta, Retrieval Amarnath Gupta, Ramesh Jain , 1997
"... ND BUSINESSMAN CALVIN MOORES COINED the term information retrieval [10] to describe the process through which a prospective user of information can convert a request for information into a useful collection of references. "Information retrieval," he wrote, "embraces the intellectual a ..."
Abstract - Cited by 283 (2 self) - Add to MetaCart
: The information sought is inherently in the form of imagery that a textual language, however powerful, is unable to express adequately, making query processing inefficient. HE ROLE OF THE EMERGING FIELD OF visual information retrieval (VIR) systems is to go beyond text-based descri

Efficient Filtering of XML Documents for Selective Dissemination of Information

by Mehmet Altınel , 2000
"... Information Dissemination applications are gaining increasing popularity due to dramatic improvements in communications bandwidth and ubiquity. The sheer volume of data available necessitates the use of selective approaches to dissemination in order to avoid overwhelming users with unnecessaryi ..."

The advent of XML as a standard for information exchangeand the development of query languages for XML data enables the development of more

A Visual Information Retrieval System

by Ma. Liza Minerva Bautista, Canlas Percival Jordan, De La, De La , 2000
"... This paper describes a tool that will use image templates as search queries instead of conventional searching using keywords. The project tries to automate searching with use of a visually oriented interface. Lastly, part of the goals of the paper is to study, select, and use relevant visual informa ..."

Computationally private information retrieval with polylogarithmic communication

by Christian Cachin, Silvio Micali, Markus Stadler - Advances in Cryptology—EUROCRYPT ’99 , 1999
"... We present a single-database computationally private information retrieval scheme with polylogarithmic communication complexity. Our construction is based on a new, but reasonable intractability assumption, which we call the Φ-Hiding Assumption (ΦHA): essentially the difficulty of deciding whether a ..."
