Multimedia information retrieval poses both technical and design challenges beyond those of established text retrieval. These issues extend both to the entry of search requests, system interation and the browsing of retrieved content, and the methodologies and techniques for content indexing. Prototype multimedia information retrieval systems are currently being developed which enable the explo...

In this paper we discuss the problem of indexing a large collection of images where each image is described by several features. Each feature de nes a multidimensional space where images are points, and the similarity between images is computed as the distance between points. We propose to approach multiple features indexing by maintaining a separate index structure for each feature, and mergin...

Indexing is one of the most important tool for efficiency enhancement, available in DMBS today. The necessity of speeding up queries in very large database systems is unquestioned. The use of new-fashioned technologies and applications such as Multimedia, E-Commerce or Geographic Information Systems in combination with commercial database systems show the shortness of current indexing mechanism...

When Mr. Bergen asked me to speak on the “Design of Bibliographic Systems,” he suggested that I discuss the experiences of the Institute for Scientific Information in using and compiling citation indexes. I shall not take advantage of Mr. Bergen’s mandate simply to repeat to this audience the mechanics and philosophy of the Science Citation Index system. Naturally it is impossible to avoid some...

some of the library & information science as well as computer specialists are considering image indexing as one of the best ways for the appropriate image storage and retrieval. therefore each, of them has tried to use different approaches and methods for image indexing. although their efforts have solved some problems of image indexing. because of the unique features of images that distinguish...
